From 404571525db92bafeddb0cf9febb21aac6613dca Mon Sep 17 00:00:00 2001
From: Jesper Nilsson <jesper@jni.nu>
Date: Mon, 14 Jul 2008 08:59:48 +0200
Subject: [CRIS] Rename boot-linkscripts and fix the path to them.

This makes the CRIS-port directories follow the same naming
convention as the rest of the kernel.

From 6902c0bead4ce266226fc0c5b3828b850bdc884a Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Subject: Input: gameport - make gameport_register_driver() return errors

Perform actual driver registration right in gameport_register_driver()
instead of offloading it to kgameportd and return proper error code to
callers if driver registration fails.

Note that driver <-> port matching is still done by kgameportd.

Subject: Input: ati_remote2 - add loadable keymap support

Support for loadable keymaps. The driver now supports individual
keymaps for each of the five modes (AUX1-AUX4 and PC) of the
remote. To achieve this the keymap scancode is interpreted as a
combination of the mode and actual button scancode. The original
keycode patches were done by Peter Stokes <linux@dadeos.co.uk>
but I modified it quite a lot.

Subject: Input: add keycodes for remote controls/phone keypads

The new keys are separate from normal numeric keys and standard
numeric keypads. The userspace should not attempt to apply modifiers
like shift and NumLock to these so tey work properly regardless of
the language mapping used.

Subject: pcmcia: only copy CIS override data once

Instead of copying CIS override data in socket_sysfs.c or ds.c, and then again
in cistpl.c, only do so once. Also, cisdump_t is now only used by the
deprecated ioctl.

By passing a gpio_button_data structure to the handler instead of the

For now this only saves a few instructions (for gpio_keys_report_event,
gpio_keys_isr and gpio_check_button one instraction each on ARM using
arm-linux-gnu-gcc 4.2.3---I assume this is similar for other arch/compiler
combinations).

Date: Tue, 19 Aug 2008 11:08:40 +0300
Subject: ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain code

This patch creates an interface to the powerdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

Each powerdomain will be defined in later patches as static
structures.  Also defined are dependencies between powerdomains,
used for adding and removing PM_WKDEP and CM_SLEEPDEP bits.  The
powerdomain structures are linked into a list at boot by
pwrdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

From d459bfe01f523983a822de8c2d3fe0bd2f2c194e Mon Sep 17 00:00:00 2001

Subject: ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain code

This patch creates an interface to the clockdomain registers in the
PRM/CM modules on OMAP2/3.  This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.

The patch also adds clockdomain usecount tracking.  This is intended
to be called whenever the first clock in a clockdomain is enabled, or
when the last enabled clock in a clockdomain is disabled.  If the
clockdomain is in software-supervised mode, the code will force-wakeup
or force-sleep the clockdomain.  If the clockdomain is in
hardware-supervised mode, the first clock enable will add sleep and
wakeup dependencies on a user-selectable set of parent domains (usually
MPU & IVA2), and the disable will remove them.

Each clockdomain will be defined in later patches as static
structures.  The clockdomain structures are linked into a list at boot
by clkdm_register(), similar to the OMAP clock code.

The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().

Subject: ARM: OMAP2: Clockdomain: Connect clockdomain code to powerdomain code

Thie patch adds code to the powerdomain layer to track the
clockdomains associated with each powerdomain.

It also modifies the clockdomain code to register clockdomains
with their corresponding powerdomain when the clockdomain is registered.

From d1b03f615ae7ede957551dd26bf8929bdc2bb786 Mon Sep 17 00:00:00 2001
From: Paul Walmsley <paul@pwsan.com>
Date: Tue, 19 Aug 2008 11:08:44 +0300
Subject: ARM: OMAP2: Clockdomain: Associate clocks with clockdomains

Associate each OMAP24xx clock in arch/arm/mach-omap2/clock24xx.h
with a clockdomain.

Also move the L4 clock up higher in the file in preparation to
define the SSI L4 iclk.

From 333943ba9e1716a3751af82f2dcc7620b83091ed Mon Sep 17 00:00:00 2001
From: Paul Walmsley <paul@pwsan.com>
Date: Tue, 19 Aug 2008 11:08:45 +0300
Subject: ARM: OMAP2: Clockdomain: Integrate OMAP3 clocks with clockdomain code

This patch integrates the OMAP3 clock tree with the clockdomain code.
This patch:

- marks OMAP34xx clocks with their corresponding clockdomain.

- adds code to convert the clockdomain name to a clockdomain pointer in the
  struct clk during clk_register().

- modifies OMAP2 clock usecounting to call into the clockdomain code
  when clocks are enabled or disabled.

From 5955902fb5c31f6a784ddb7aa16079a2bec588f5 Mon Sep 17 00:00:00 2001

Subject: ARM: OMAP2: Clock: Combine 34xx l3_icks and l4_icks

E.g dss_l3_ick and dss_l4_ick have same gating control. Having own
clock for both of them causes race condition between enable / disable.

This patch combines this kind of clocks and names new clock as <module>_ick.

Subject: powerpc: Streamline ret_from_except_lite for non-iSeries platforms

There is a small passage of code in ret_from_except_lite which is
only required on iSeries.  For a multi-platform kernel on non-iSeries
machines this means we end up executing ~15 nops in ret_from_except_lite.

It would be nicer if non-iSeries could skip the code entirely, and on
iSeries we can jump out of line to execute the code.

I have no performance numbers to justify this, other than the assertion
that executing 15 nops takes longer than executing 0.

Subject: powerpc: Split-out common MSI bitmap logic into msi_bitmap.c

There are now two almost identical implementations of an MSI bitmap
allocator, one in mpic_msi.c and the other in fsl_msi.c.

Merge them together and put the result in msi_bitmap.c.  Some of the
MPIC bits will remain to provide a nicer interface for the MPIC users.

In the process we fix two buglets.  The first is that the allocation
routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result,
even though they use -1 to indicate allocation failure.  Although all
the callers were checking correctly, it is much better for the routine
to just return an int.  At least until someone wants > ~2 billion MSIs.

The second buglet is that the device tree reservation logic only
allowed power-of-two reservations.  AFAICT that didn't effect any
existing code but it's nicer if we can reserve arbitrary irqs from MSI
use.

We also add some selftests, which exposed the two buglets and now test

when CONFIG_DEBUG_KERNEL=y.

Subject: powerpc: Convert the FSL MSI code to use msi_bitmap

This is 90% straight forward, although we have to change a few
printk format strings as well because of the change in type of hwirq.

Subject: powerpc: Convert the MPIC MSI code to use msi_bitmap

This affects the U3 MSI code as well as the PASEMI MSI code.  We keep
some of the MPIC routines as helpers, and also the U3 best-guess
reservation logic.  The rest is replaced by the generic code.

And a few printk format changes due to hwirq type change.

Subject: powerpc: Update in-kernel dtc and libfdt to version 1.2.0

Some time ago, a copies of the upstream dtc and libfdt sources were
included in the kernel tree to avoid having these as external
dependencies for building the kernel.  Since then development on the
upstream dtc and libfdt has continued.  This updates the in-kernel
versions to match the recently released upstream dtc version 1.2.0.
This includes a number of bugfixes, many cleanups and a few new
features.

Subject: powerpc: Remove redundant sysfs_remove_file calls for cache info

When removing a directory, the sysfs core takes care of removing files
in the directory (see sysfs_remove_dir()).  So when we are about to
delete a kobject (and thus cause its sysfs directory to be removed),
we don't have to explicitly remove the files attached to it, although
it's harmless to do so.

Subject: powerpc: Expose PMCs & cache topology in sysfs on 32-bit

The file arch/powerpc/kernel/sysfs.c is currently only compiled for
64-bit kernels.  It contain code to register CPU sysdevs in sysfs and
add various properties such as cache topology and raw access by root
to performance monitor counters (PMCs).  A lot of that can be re-used
as is on 32-bits.

This makes the file be built for both, with appropriate ifdef'ing
for the few bits that are really 64-bit specific, and adds some
support for the raw PMCs for 75x and 74xx processors.

Subject: [ARM] OMAP3 pwrdm: add hardware save-and-restore (SAR) support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OMAP3430ES2+ introduces a new feature: optional powerdomain context
hardware save-and-restore (SAR).  Currently, this feature only applies
to USBHOST and USBTLL module context when the USBHOST or CORE
powerdomains enter a low-power sleep state[1].  This feature avoids
re-enumeration of USB devices when the powerdomains return from idle,
which is potentially time-consuming.

This patch adds support for enabling and disabling hardware
save-and-restore to the powerdomain code.  Three new functions are
added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and
pwrdm_can_hdwr_sar().  A new struct powerdomain "flags" field is
added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with
SAR support.

Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an
earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com>
for clarifying the purpose of these bits.

1.  For the USBHOST controller module, context loss occurs when the
    USBHOST powerdomain enters off-idle.  For USBTLL, context loss
    occurs either if CORE enters off-idle, or if the CORE logic is
    configured to turn off when CORE enters retention-idle (OSWR).

Subject: pcmcia: add pcmcia_loop_config() helper

By calling pcmcia_loop_config(), a pcmcia driver can iterate over all
available configuration options. During a driver's probe() phase, one
doesn't need to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data
and pcmcia_parse_tuple directly in most if not all cases.

From 498ac1899b62626bf6879a251d75c22ec564c559 Mon Sep 17 00:00:00 2001
From: Dominik Brodowski <linux@dominikbrodowski.net>
Date: Sat, 2 Aug 2008 14:59:13 +0200
Subject: pcmcia: pcmcia_config_loop() ConfigIndex unification

Almost all drivers set p_dev->conf.ConfigIndex to cfg->index in
the pcmcia_config_loop() callback function. Therefore, factor it out.

From 8e2fc39ddea7fe8c6798837da282db88a09af793 Mon Sep 17 00:00:00 2001
From: Dominik Brodowski <linux@dominikbrodowski.net>
Date: Sat, 2 Aug 2008 15:30:31 +0200
Subject: pcmcia: pcmcia_config_loop() default CIS entry handling

Many drivers use the default CIS entry within their pcmcia_config_loop()
callback function. Therefore, factor the default CIS entry handling out.

From ad913c11928f51abb6174f165db8d8d205b22e21 Mon Sep 17 00:00:00 2001
From: Dominik Brodowski <linux@dominikbrodowski.net>
Date: Sat, 2 Aug 2008 16:12:00 +0200
Subject: pcmcia: pcmcia_config_loop() improvement by passing vcc

By passing the current Vcc setting to the pcmcia_config_loop callback
function, we can remove pcmcia_get_configuration_info() calls from many
drivers.

Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

Remove the three remaining pcmcia_get_configuration_info() users:
- pcmciamtd is marked broken anyway.
- serial_cs.c can access the relevant structs directly
- ipwireless didn't use the output

From 4c89e88bfde6a3c179790e21004f24e09a058290 Mon Sep 17 00:00:00 2001
From: Dominik Brodowski <linux@dominikbrodowski.net>
Date: Sun, 3 Aug 2008 10:07:45 +0200
Subject: pcmcia: deprecate CS_SUCCESS

Instead of using own error or success codes, the PCMCIA code should rely on
the generic return values. Therefore, replace all occurrences of CS_SUCCESS
with 0.

Subject: pcmcia: deprecate CS_OUT_OF_RESOURCE

CS_OUT_OF_RESOURCE was almost only used to note -ENOMEM situations.
Therefore, use -ENOMEM explicitely, and also print out warnings.

CS_BAD_HANDLE means that something went badly wrong: no parameter was passed,
or the paramater passed wasn't the correct one. Therefore, replace it with
-EINVAL.

If a resource is already in use, mark it with -EBUSY. Same for cards already
asleep.

Subject: pcmcia: deprecate CS_NO_MORE_ITEMS

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.

CS_BAD_TYPE was only used in cs.c and already properly annotated by error

ds_dbg() output and -EINVAL seems to be enough.

Subject: pcmcia: deprecate CS_BAD_BASE, CS_BAD_IRQ, CS_BAD_OFFSET and
 CS_BAD_SIZE

These four error values mostly mean a badly written driver, so ds_dbg()
output and -EINVAL seems to be enough.

Subject: pcmcia: remove CS_ error codes alltogether

Remoe the CS_ error codes. Drivers are expected to use default
error definitions (errno.h etc.).

Only one CS_ error code -- CS_IN_USE -- is used internally by the
(deprecated) pcmcia-cs userspace package. Therefore, keep this one
around so that it still compiles.

Subject: pcmcia: use dev_printk for cs_error()

Use dev_printk() in cs_error()-based error reporting. While this
function-turned-macro will hopefully go away soon, using dev_printk
simplifies the code much.

Subject: powerpc/44x: Add PowerPC 44x simple platform support

This adds a common board file for almost all of the "simple" PowerPC 44x
boards that exist today.  This is intended to be a single place to add
support for boards that do not differ in platform support from most of the
evaluation boards that are used as reference platforms.  Boards that have
specific requirements or custom hardware setup should still have their own
board.c file.

Subject: pcmcia: cleanup device driver header file

The header file primarily used for (in-kernel) PCMCIA device drivers
also deserved a major cleanup. This header file also serves as the dumping
ground for all typedefs and definitions only used by the deprecated PCMCIA
ioctl and the deprecated PCMCIA userspace tools using this ioctl.

Subject: pcmcia: encapsulate ioaddr_t

By now, ioaddr_t should only be used by the deprecated ioctl, as it does not
correctly reflect the maximum ioport range at least on some architectures.

Subject: pcmcia: device_id header cleanup

Wrap in #ifdef to include header just once, and wrap in another #ifdef
to avoid it being used in userspace. Also, format the header similar to
the other PCMCIA header files.

From 2f3061eb1086f98990d6495b8c63a1b83f2f59aa Mon Sep 17 00:00:00 2001
From: Dominik Brodowski <linux@dominikbrodowski.net>
Date: Sun, 31 Aug 2008 15:50:33 +0200
Subject: pcmcia: remove unused argument to pcmcia_parse_tuple()

Since we're just parsing the tuple being passed to this function, we don't
need any device-specific information.

Also, remove the call to pcmcia_validate_cis() from pcmciamtd.c, since it
is already called by the PCMCIA core.

From: Ilya Yanok <yanok@emcraft.com>
Date: Mon, 1 Sep 2008 17:53:22 +1000
Subject: powerpc/4xx: Necessary fixes to PCI for 4GB RAM size

The declaration of total_memory removed.  Now including <mm/mmu_decl.h>
instead.  Since total_memory is a phys_addr_t which is 64-bit on 44x and
is_power_of_2() works with u32 so I just inlined (size & (size-1)) != 0
instead.

Also this patch fixes default initialization: res->end should be 0x7fffffff
not 0x80000000.

We don't have any suitable value to put in f_fsid. Using EFS_MAGIC
really isn't a good idea, because all EFS file systems will have the
same f_fsid then.

Also, stop looking at the NAND controller (0x4100) and checking the

chip had the same ID. We made them fix that fairly promptly, and we can
forget about it now.

Subject: Make <asm-generic/statfs.h> suitable for 64-bit platforms.

At the moment, 64-bit platforms (other than Alpha) are all redefining
things for themselves instead of using <asm-generic/statfs.h>.

As is ARM, since it has special requirements w.r.t. padding.

Make <asm-generic/statfs.h> more generic, and they can use it directly.

Subject: IO resources: fix/remove printk

Andrew Morton noticed that the printk in kernel/resource.c was buggy:

| start and end have type resource_size_t.  Such types CANNOT be printed
| unless cast to a known type.
|
| Because there is a %s following an incorrect %lld, the above code will
| crash the machine.

... and it's probably quite unneeded as well, so remove it.

Subject: [ARM] omap: Fix IO_ADDRESS() macros

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers.  Therefore,
these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

Subject: [ARM] omap: fix inappropriate casting in gpio.c

gpio.c wilfully casts physical addresses to void __iomem * and then
fixes them up at runtime using:

	bank->base = IO_ADDRESS(bank->base);

where accesses prior to this fixup are via omap_read/omap_write, and
after are by __raw_read/__raw_write.  This doesn't lend itself to
static checking, nor to easy understanding of the code.

And so, OMAP_MPUIO_BASE gets to be the right type - integer like since
it's a physical address, not a MMIO pointer.

Subject: Introduce HAVE_AOUT symbol to remove hard-coded arch list for
 BINFMT_AOUT

HAVE_AOUT doesn't quite do the same thing as the recently removed
ARCH_SUPPORTS_AOUT config option. That was set even on platforms where
binfmt_aout isn't supported, although it's not entirely clear why.

So it's best just to introduce a new symbol, handled consistently with
other similar HAVE_xxx symbols; with a simple 'select' in the arch Kconfig.

Subject: Input: convert drivers to use strict_strtoul()

strict_strtoul() allows newline character at the end of the the input
string and therefore is more user-friendly.

Subject: Input: atkbd - expand Latitude's force release quirk to other Dells

Dell laptops fail to send key up events for several of their special
keys. There's an existing quirk in the kernel to handle this, but it's
limited to the Latitude range. This patch extends it to cover all
portable Dells.

Subject: Input: serio_raw - allow attaching to translated (SERIO_I8042XL)
 ports

serio_raw only binds to non-translated devices. Enable serio_raw to
bind to normal (translated) keyboards which can have non-standard
extensions (like POS Keyboards). With this it is possible to send
commands to the device over /dev/serio_raw<n>.

Subject: Input: ads7846 - introduce .gpio_pendown to get pendown state

The GPIO connected to ADS7846 nPENIRQ signal is usually used to get
the pendown state as well. Introduce a .gpio_pendown, and use this
to decide the pendown state if .get_pendown_state is NULL.

Subject: generic: add phys_addr_t for holding physical addresses

Add a kernel-wide "phys_addr_t" which is guaranteed to be able to hold
any physical address.  By default it equals the word size of the
architecture, but a 32-bit architecture can set ARCH_PHYS_ADDR_T_64BIT
if it needs a 64-bit phys_addr_t.

Subject: generic: make PFN_PHYS explicitly return phys_addr_t

PFN_PHYS, as its name suggests, turns a pfn into a physical address.
However, it is a macro which just operates on its argument without
modifying its type.  pfns are typed unsigned long, but an unsigned
long may not be long enough to hold a physical address (32-bit systems
with more than 32 bits of physcial address).

Make sure we cast to phys_addr_t to return a complete result.

There's no good reason why a resource_size_t shouldn't just be a
physical address, so simply redefine it in terms of phys_addr_t.

Subject: powerpc: Add new CPU feature: CPU_FTR_CP_USE_DCBTZ

Add a new CPU feature bit, CPU_FTR_CP_USE_DCBTZ, to be added to the
64bit powerpc chips that benefit from having dcbt and dcbz
instructions used in their memory copy routines.

This will be used in a subsequent patch that updates copy_4K_page().
The new bit is added to Cell, PPC970 and Power4 because they show
better performance with the new copy_4K_page() when dcbt and dcbz
instructions are used.

Subject: powerpc: New copy_4K_page()

This new copy_4K_page() function was originally tuned for the best
performance on the Cell processor, but after testing on more 64bit
powerpc chips it was found that with a small modification it either
matched the performance offered by the current mainline version or
bettered it by a small amount.

It was found that on a Cell-based QS22 blade the amount of system
time measured when compiling a 2.6.26 pseries_defconfig decreased
by 4%. Using the same test, a 4-way 970MP machine saw a decrease of
2% in system time. No noticeable change was seen on Power4, Power5
or Power6.

The 4096 byte page is copied in thirty-two 128 byte strides. An
initial setup loop executes dcbt instructions for the whole source
page and dcbz instructions for the whole destination page. To do
this, the cache line size is retrieved from ppc64_caches.

A new CPU feature bit, CPU_FTR_CP_USE_DCBTZ, (introduced in the
previous patch) is used to make the modification to this new copy
routine - on Power4, 970 and Cell the feature bit is set so the
setup loop is executed, but on all other 64bit chips the setup
loop is nop'ed out.

Subject: powerpc: Check rc of notifier chain for memory remove

The return code from invocation of the notifier for
pSeries_reconfig_chain during update of the device tree is not
checked.  This causes writes to /proc/ppc64/ofdt to update memory
properties (i.e. ibm,dyamic-reconfiguration-memory) to always
return success, instead of the result of the notifier chain.

This happens specifically when we remove/add memory from the
device tree on machines using memory specified in the
ibm,dynamic-reconfiguration-memory property of the device tree.

Subject: powerpc: Add support for dynamic reconfiguration memory in
 kexec/kdump kernels

Kdump kernel needs to use only those memory regions that it is allowed
to use (crashkernel, rtas, tce, etc.).  Each of these regions have
their own sizes and are currently added under 'linux,usable-memory'
property under each memory@xxx node of the device tree.

The ibm,dynamic-memory property of ibm,dynamic-reconfiguration-memory
node (on POWER6) now stores in it the representation for most of the
logical memory blocks with the size of each memory block being a
constant (lmb_size).  If one or more or part of the above mentioned
regions lie under one of the lmb from ibm,dynamic-memory property,
there is a need to identify those regions within the given lmb.

This makes the kernel recognize a new 'linux,drconf-usable-memory'
property added by kexec-tools.  Each entry in this property is of the
form of a count followed by that many (base, size) pairs for the above
mentioned regions.  The number of cells in the count value is given by
the #size-cells property of the root node.

Subject: powerpc: Rearrange head_64.S to move interrupt handler code to the
 beginning

This rearranges head_64.S so that we have all the first-level exception
prologs together starting at 0x100, followed by all the second-level
handlers that are invoked from the first-level prologs, followed by
other code.  This doesn't make any functional change but will make
following changes for relocatable kernel support easier.

Subject: powerpc: Make it possible to move the interrupt handlers away from
 the kernel

This changes the way that the exception prologs transfer control to
the handlers in 64-bit kernels with the aim of making it possible to
have the prologs separate from the main body of the kernel.  Now,
instead of computing the address of the handler by taking the top
32 bits of the paca address (to get the 0xc0000000........ part) and
ORing in something in the bottom 16 bits, we get the base address of
the kernel by doing a load from the paca and add an offset.

This also replaces an mfmsr and an ori to compute the MSR value for
the handler with a load from the paca.  That makes it unnecessary to
have a separate version of EXCEPTION_PROLOG_PSERIES that forces 64-bit
mode.

We can no longer use a direct branches in the exception prolog code,
which means that the SLB miss handlers can't branch directly to
.slb_miss_realmode any more.  Instead we have to compute the address
and do an indirect branch.  This is conditional on CONFIG_RELOCATABLE;
for non-relocatable kernels we use a direct branch as before.  (A later
change will allow CONFIG_RELOCATABLE to be set on 64-bit powerpc.)

Since the secondary CPUs on pSeries start execution in the first 0x100
bytes of real memory and then have to get to wherever the kernel is,
we can't use a direct branch to get there.  Instead this changes
__secondary_hold_spinloop from a flag to a function pointer.  When it
is set to a non-NULL value, the secondary CPUs jump to the function
pointed to by that value.

Finally this eliminates one code difference between 32-bit and 64-bit
by making __secondary_hold be the text address of the secondary CPU
spinloop rather than a function descriptor for it.

From e31aa453bbc4886a7bd33e5c2afa526d6f55bd7a Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Sat, 30 Aug 2008 11:41:12 +1000
Subject: powerpc: Use LOAD_REG_IMMEDIATE only for constants on 64-bit

Using LOAD_REG_IMMEDIATE to get the address of kernel symbols
generates 5 instructions where LOAD_REG_ADDR can do it in one,
and will generate R_PPC64_ADDR16_* relocations in the output when
we get to making the kernel as a position-independent executable,
which we'd rather not have to handle.  This changes various bits
of assembly code to use LOAD_REG_ADDR when we need to get the
address of a symbol, or to use suitable position-independent code
for cases where we can't access the TOC for various reasons, or
if we're not running at the address we were linked at.

It also cleans up a few minor things; there's no reason to save and
restore SRR0/1 around RTAS calls, __mmu_off can get the return
address from LR more conveniently than the caller can supply it in
R4 (and we already assume elsewhere that EA == RA if the MMU is on
in early boot), and enable_64b_mode was using 5 instructions where
2 would do.

From 549e8152de8039506f69c677a4546e5427aa6ae7 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Sat, 30 Aug 2008 11:43:47 +1000
Subject: powerpc: Make the 64-bit kernel as a position-independent executable

This implements CONFIG_RELOCATABLE for 64-bit by making the kernel as
a position-independent executable (PIE) when it is set.  This involves
processing the dynamic relocations in the image in the early stages of
booting, even if the kernel is being run at the address it is linked at,
since the linker does not necessarily fill in words in the image for
which there are dynamic relocations.  (In fact the linker does fill in
such words for 64-bit executables, though not for 32-bit executables,
so in principle we could avoid calling relocate() entirely when we're
running a 64-bit kernel at the linked address.)

The dynamic relocations are processed by a new function relocate(addr),
where the addr parameter is the virtual address where the image will be
run.  In fact we call it twice; once before calling prom_init, and again
when starting the main kernel.  This means that reloc_offset() returns
0 in prom_init (since it has been relocated to the address it is running
at), which necessitated a few adjustments.

This also changes __va and __pa to use an equivalent definition that is
simpler.  With the relocatable kernel, PAGE_OFFSET and MEMORY_START are
constants (for 64-bit) whereas PHYSICAL_START is a variable (and
KERNELBASE ideally should be too, but isn't yet).

With this, relocatable kernels still copy themselves down to physical
address 0 and run there.

Subject: powerpc: Separate the irq radix tree insertion and lookup

irq_radix_revmap() currently serves 2 purposes, irq mapping lookup
and insertion which happen in interrupt and process context respectively.

Separate the function into its 2 components, one for lookup only and one
for insertion only.

Fix the only user of the revmap tree (XICS) to use the new functions.

Also, move the insertion into the radix tree of those irqs that were
requested before it was initialized at said tree initialization.

Mutual exclusion between the tree initialization and readers/writers is
handled via a state variable (revmap_trees_allocated) set to 1 when the tree
has been initialized and set to 2 after the already requested irqs have been
inserted in the tree by the init path. This state is checked before any reader
or writer access just like we used to check for tree.gfp_mask != 0 before.

Finally, now that we're not any longer inserting nodes into the radix-tree
in interrupt context, turn the GFP_ATOMIC allocations into GFP_KERNEL ones.

Subject: powerpc: Make the irq reverse mapping radix tree lockless

The radix trees used by interrupt controllers for their irq reverse
mapping (currently only the XICS found on pSeries) have a complex
locking scheme dating back to before the advent of the lockless radix
tree.

This takes advantage of the lockless radix tree and of the fact that
the items of the tree are pointers to a static array (irq_map)
elements which can never go under us to simplify the locking.

Concurrency between readers and writers is handled by the intrinsic
properties of the lockless radix tree.  Concurrency between writers is
handled with a global mutex.

Subject: powerpc: Clean up hugepage pagetable allocation for powerpc with 16G
 pages

There is a small bug in the handling of 16G hugepages recently added
to the kernel.  This doesn't cause a crash or other user-visible
problems, but it does mean that more levels of pagetable are allocated
than makes sense for 16G pages.  The hugepage pagetables for the 16G
pages are allocated much lower in the pagetable tree than they should
be, with the intervening levels allocated with full pmd and pud pages
which will only ever have one entry filled in.

This corrects this problem, at the same time cleaning up the handling
of which level 64k versus 16M hugepage pagetables are allocated at.
The new way of formatting the tests should be more robust against
changes in pagetable structure, or any newly added hugepage sizes.

Subject: powerpc: Fix major revision number for Freescale cores

Some 74xx cores by Freescale are using the configuration field instead
of the major revision field for their revision number.  This corrects
the wrong behaviour for those ppc cores including my one.

There is a reference document at Freecale.  It describes the PVR
register.  This is based on that pdf.  You can find the document at:

http://www.freescale.com/files/archives/doc/support_info/PPCPVR.pdf

Subject: serial/cpm_uart: Remove dead Kconfig options

With the change to device tree based setup we no longer need the explicit
Kconfig options for each SCC{1,4} or SMC{1,2} port.

Subject: powerpc/83xx: mpc836x_mds: add support for the nor flash

This patch adds the localbus node, moves the bcsr node into the
localbus node, and adds the flash node.

Also enable MTD support in the defconfig.

Subject: powerpc/85xx: fix build warning, remove silly cast

This fixes a build warning when PHYS_64BIT is enabled, and removes an
unnecessary cast to phys_addr_t (the variable being cast is already
a phys_addr_t)

Subject: math-emu: Add support for reporting exact invalid exception

Some architectures (like powerpc) provide status information on the exact
type of invalid exception.  This is pretty straight forward as we already
report invalid exceptions via FP_SET_EXCEPTION.

We add new flags (FP_EX_INVALID_*) the architecture code can define if it
wants the exact invalid exception reported.

We had to split out the INF/INF and 0/0 cases for divide to allow reporting
the two invalid forms properly.

From f1eaf16a9e843aa915b86594b60ec6cd66c9eac7 Mon Sep 17 00:00:00 2001
From: Jochen Friedrich <jochen@scram.de>
Date: Wed, 27 Aug 2008 12:32:25 +0200
Subject: powerpc/cpm1: Fix race condition in CPM1 GPIO library.

The CPM1 GPIO library code uses the non thread-safe clrbits32/setbits32
macros. This patch protects them with a spinlock.

Based on the CPM2 patch from Laurent Pinchart <laurentp@cse-semaphore.com>,
commit 639d64456e20cbfc866b18dc03cf9f9babc9c7cd.

Subject: powerpc: add SSI-to-DMA properties to Freescale MPC8610 HPCD device
 tree

Add the fsl,playback-dma and fsl,capture-dma properties to the Freescale
MPC8610 HPCD device tree.  These properties connect the SSI nodes to the
DMA nodes for the DMA channels that the SSI should use.  Also update the
ssi.txt documentation.

These properties will be needed when the ASoC V2 version of the Freescale
MPC8610 device drivers are merged into the mainline.

+Notes on fsl,playback-dma and fsl,capture-dma:
+
+On SOCs that have an SSI, specific DMA channels are hard-wired for playback
+and capture.  On the MPC8610, for example, SSI1 must use DMA channel 0 for
+playback and DMA channel 1 for capture.  SSI2 must use DMA channel 2 for
+playback and DMA channel 3 for capture.  The developer can choose which
+DMA controller to use, but the channels themselves are hard-wired.  The
+purpose of these two properties is to represent this hardware design.

Subject: dmi scan: warn about too early calls to dmi_check_system()

It happened to me recently that i added a dmi_check_system() quirk
in a too early codepath, and it was silently ignored because all the
DMI tables and strings were still empty.

As this situation is clearly a programming error / kernel bug,
warn when it happens, instead of silently ignoring quirks.

Subject: Input: psmouse - add psmouse_queue_work() for ps/2 extension to make
 use of

psmouse_queue_work is passed a delayed_work struct, and queues up the work
with kpsmouse_wq.  Since we're dealing with delayed_work stuff, this
also switches resync_work to a delayed_work struct as well, and makes
use of psmouse_queue_work when doing a resync within psmouse-base.

Subject: Input: psmouse - tweak PSMOUSE_DEFINE_ATTR to support raw set
 callbacks

We want to support attr->set callbacks that may need psmouse->state to
not be updated, or may want to manually deal w/ enabling and disabling
the device.  To do that, we create __PSMOUSE_DEFINE_ATTR which enables
us to set a 'protect' argument specifying whether or not the set
callback should be protected with psmouse_disable and state setting.

Subject: Input: psmouse - add OLPC touchpad driver

This adds support for OLPC's touchpad.  It has lots of neat features,
none of which are enabled because the hardware is too buggy.  Instead,
we use it like a normal touchpad, but with a number of workarounds in
place to deal with the frequent hardware spasms.  Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

+GPIO controllers on MPC8xxx SoCs
+
+This is for the non-QE/CPM/GUTs GPIO controllers as found on
+8349, 8572, 8610 and compatible.
+
+Every GPIO controller node must have #gpio-cells property defined,
+this information will be used to translate gpio-specifiers.
+
+Required properties:
+- compatible : "fsl,<CHIP>-gpio" followed by "fsl,mpc8349-gpio" for
+  83xx, "fsl,mpc8572-gpio" for 85xx and "fsl,mpc8610-gpio" for 86xx.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+  second cell is used to specify optional parameters (currently unused).
+ - interrupts : Interrupt mapping for GPIO IRQ (currently unused).
+ - interrupt-parent : Phandle for the interrupt controller that
+   services interrupts for this device.
+- gpio-controller : Marks the port as GPIO controller.
+
+Example of gpio-controller nodes for a MPC8347 SoC:
+
+	gpio1: gpio-controller@c00 {
+		#gpio-cells = <2>;
+		compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
+		reg = <0xc00 0x100>;
+		interrupts = <74 0x8>;
+		interrupt-parent = <&ipic>;
+		gpio-controller;
+	};
+
+	gpio2: gpio-controller@d00 {
+		#gpio-cells = <2>;
+		compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
+		reg = <0xd00 0x100>;
+		interrupts = <75 0x8>;
+		interrupt-parent = <&ipic>;
+		gpio-controller;
+	};
+
+See booting-without-of.txt for details of how to specify GPIO
+information for devices.

Subject: powerpc: convert CONFIG_PPC_MERGE to CONFIG_PPC for legacy io checks

Now that arch/ppc is dead CONFIG_PPC_MERGE is always defined for all
powerpc platforms and we want to get rid of CONFIG_PPC_MERGE use
CONFIG_PPC instead.

From ee1130197e7d64a436dbf7feab0bb77065baf5e8 Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>
Date: Tue, 23 Sep 2008 23:32:32 -0500
Subject: powerpc/86xx: Introduce a generic mpc86xx_defconfig

Introduced a mpc86xx_defconfig that enables all 86xx boards and moved
all other 86xx related defconfigs under configs/86xx to match 83xx
and 85xx.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Subject: powerpc: Move 8xxx GPIO Kconfig under the platform menu

The initial patch had the option at the top level which wasn't
quite right.  Moving under the platform options is a bit better.

From 8dd0e95206f7c33bed2aed33ac668335174684e8 Mon Sep 17 00:00:00 2001
From: Becky Bruce <becky.bruce@freescale.com>
Date: Mon, 8 Sep 2008 09:09:53 +0000
Subject: powerpc: Move iommu dma ops from dma.c to dma-iommu.c

32-bit platforms are about to start using dma.c; move the iommu
dma ops into their own file to make this a bit cleaner.

From 4fc665b88a79a45bae8bbf3a05563c27c7337c3d Mon Sep 17 00:00:00 2001
From: Becky Bruce <becky.bruce@freescale.com>
Date: Fri, 12 Sep 2008 10:34:46 +0000
Subject: powerpc: Merge 32 and 64-bit dma code

We essentially adopt the 64-bit dma code, with some changes to support
32-bit systems, including HIGHMEM.  dma functions on 32-bit are now
invoked via accessor functions which call the correct op for a device based
on archdata dma_ops.  If there is no archdata dma_ops, this defaults
to dma_direct_ops.

In addition, the dma_map/unmap_page functions are added to dma_ops
because we can't just fall back on map/unmap_single when HIGHMEM is
enabled. In the case of dma_direct_*, we stop using map/unmap_single
and just use the page version - this saves a lot of ugly
ifdeffing.  We leave map/unmap_single in the dma_ops definition,
though, because they are needed by the iommu code, which does not
implement map/unmap_page.  Ideally, going forward, we will completely
eliminate map/unmap_single and just have map/unmap_page, if it's
workable for 64-bit.

Subject: powerpc: Introduce local (non-broadcast) forms of tlb invalidates

Introduced a new set of low level tlb invalidate functions that do not
broadcast invalidates on the bus:

_tlbil_all - invalidate all
_tlbil_pid - invalidate based on process id (or mm context)
_tlbil_va  - invalidate based on virtual address (ea + pid)

On non-SMP configs _tlbil_all should be functionally equivalent to _tlbia and
_tlbil_va should be functionally equivalent to _tlbie.

The intent of this change is to handle SMP based invalidates via IPIs instead
of broadcasts as the mechanism scales better for larger number of cores.

On e500 (fsl-booke mmu) based cores move to using MMUCSR for invalidate alls
and tlbsx/tlbwe for invalidate virtual address.

Subject: powerpc: Fixes for CONFIG_PTE_64BIT for SMP support

There are some minor issues with support 64-bit PTEs on a 32-bit processor
when dealing with SMP.

* We need to order the stores in set_pte_at to make sure the flag word
  is set second.
* Change pte_clear to use pte_update so only the flag word is cleared
* Added a WARN_ON to set_pte_at to ensure the pte isn't present for
  the 64-bit pte/SMP case (to ensure our assumption of this fact).

Subject: powerpc/mm: Implement _PAGE_SPECIAL & pte_special() for 32-bit

Implement _PAGE_SPECIAL and pte_special() for 32-bit powerpc. This bit will
be used by the fast get_user_pages() to differenciate PTEs that correspond
to a valid struct page from special mappings that don't such as IO mappings
obtained via io_remap_pfn_ranges().

We currently only implement this on sub-arch that support SMP or will so
in the future (6xx, 44x, FSL-BookE) and not (8xx, 40x).

Subject: POWERPC: Allow 32-bit hashed pgtable code to support 36-bit physical

This rearranges a bit of code, and adds support for
36-bit physical addressing for configs that use a
hashed page table.  The 36b physical support is not
enabled by default on any config - it must be
explicitly enabled via the config system.

This patch *only* expands the page table code to accomodate
large physical addresses on 32-bit systems and enables the
PHYS_64BIT config option for 86xx.  It does *not*
allow you to boot a board with more than about 3.5GB of
RAM - for that, SWIOTLB support is also required (and
coming soon).

Subject: IO resources, x86: ioremap sanity check to catch mapping requests
 exceeding the BAR sizes

Go through the iomem resource tree to check if any of the ioremap()
requests span more than any slot in the iomem resource tree and do
a WARN_ON() if we hit this check.

This will raise a red-flag, if some driver is mapping more than what
is needed. And hopefully identify possible corruptions much earlier.

initcall ibmphp_init+0x0/0x360 returned -19 after 144 msecs
calling  zt5550_init+0x0/0x6a @ 1

the problem is this code:

        io_mem = ioremap (ebda_seg<<4, 65000);

it assumes that the EBDA is 65000 bytes. But BIOS EBDA pointers are
at most 1K large.

_if_ the Rio code truly extends upon the customary EBDA size it needs
to iounmap() this memory and ioremap() it larger, once it knows it from
the generic descriptors that a Rio system is around.

For many of the embedded boards, "model" and "Machine" are printing
the same thing; remove the redundant code and allow the generic
show_cpuinfo to print the model information.

Subject: powerpc: Correct USB support for GE Fanuc SBC610

Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC
MPC8641D).

Fixup to correctly reconfigure USB, provided by an NEC uPD720101, after
device is reset. This requires a set of chip specific registers in the
devices configuration space to be correctly written, enabling all ports
and switching the device to use an external 48-MHz Oscillator.

Subject: SUNRPC: Use proper INADDR_ANY when setting up RPC services on IPv6

Teach svc_create_xprt() to use the correct ANY address for AF_INET6 based
RPC services.

No caller uses AF_INET6 yet.

Subject: nfsd: permit unauthenticated stat of export root

RFC 2623 section 2.3.2 permits the server to bypass gss authentication
checks for certain operations that a client may perform when mounting.
In the case of a client that doesn't have some form of credentials
available to it on boot, this allows it to perform the mount unattended.
(Presumably real file access won't be needed until a user with
credentials logs in.)

Being slightly more lenient allows lots of old clients to access
krb5-only exports, with the only loss being a small amount of
information leaked about the root directory of the export.

This affects only v2 and v3; v4 still requires authentication for all
access.

Thanks to Peter Staubach testing against a Solaris client, which
suggesting addition of v3 getattr, to the list, and to Trond for noting
that doing so exposes no additional information.

Subject: Configure out file locking features

This patch adds the CONFIG_FILE_LOCKING option which allows to remove
support for advisory locks. With this patch enabled, the flock()
system call, the F_GETLK, F_SETLK and F_SETLKW operations of fcntl()
and NFS support are disabled. These features are not necessarly needed
on embedded systems. It allows to save ~11 Kb of kernel code and data:

   text          data     bss     dec     hex filename
1125436        118764  212992 1457192  163c28 vmlinux.old
1114299        118564  212992 1445855  160fdf vmlinux

Subject: nfsd: fix nfsd4_encode_open buffer space reservation

nfsd4_encode_open first reservation is currently for 36 + sizeof(stateid_t)
while it writes after the stateid a cinfo (20 bytes) and 5 more 4-bytes
words, for a total of 40 + sizeof(stateid_t).

Subject: nfsd: don't declare p in ENCODE_SEQID_OP_HEAD

After using the encode_stateid helper the "p" pointer declared
by ENCODE_SEQID_OP_HEAD is warned as unused.
In the single site where it is still needed it can be declared
separately using the ENCODE_HEAD macro.

Subject: knfsd: allocate readahead cache in individual chunks

I had a report from someone building a large NFS server that they were
unable to start more than 585 nfsd threads. It was reported against an
older kernel using the slab allocator, and I tracked it down to the
large allocation in nfsd_racache_init failing.

It appears that the slub allocator handles large allocations better,
but large contiguous allocations can often be problematic. There
doesn't seem to be any reason that the racache has to be allocated as a
single large chunk. This patch breaks this up so that the racache is
built up from separate allocations.

(Thanks also to Takashi Iwai for a bugfix.)

Subject: locks: allow lockd to process blocked locks during grace period

The check here is currently harmless but unnecessary, since, as the
comment notes, there aren't any blocked-lock callbacks to process
during the grace period anyway.

And eventually we want to allow multiple grace periods that come and go
for different filesystems over the course of the lifetime of lockd, at
which point this check is just going to get in the way.

Subject: lockd: don't depend on lockd main loop to end grace

End lockd's grace period using schedule_delayed_work() instead of a
check on every pass through the main loop.

After a later patch, we'll depend on lockd to end its grace period even
if it's not currently handling requests; so it shouldn't depend on being
woken up from the main loop to do so.

Also, Nakano Hiroaki (who independently produced a similar patch)
noticed that the current behavior is buggy in the face of jiffies
wraparound:

	"lockd uses time_before() to determine whether the grace period
	has expired. This would seem to be enough to avoid timer
	wrap-around issues, but, unfortunately, that is not the case.
	The time_* family of comparison functions can be safely used to
	compare jiffies relatively close in time, but they stop working
	after approximately LONG_MAX/2 ticks. nfsd can suffer this
	problem because the time_before() comparison in lockd() is not
	performed until the first request comes in, which means that if
	there is no lockd traffic for more than LONG_MAX/2 ticks we are
	screwed.

	"The implication of this is that once time_before() starts
	misbehaving any attempt from a NFS client to execute fcntl()
	will be received with a NLM_LCK_DENIED_GRACE_PERIOD message for
	25 days (assuming HZ=1000). In other words, the 50 seconds grace
	period could turn into a grace period of 50 days or more.

	"Note: This bug was analyzed independently by Oda-san
	<oda@valinux.co.jp> and myself."

Subject: SUNRPC: Set V6ONLY socket option for RPC listener sockets

My plan is to use an AF_INET listener on systems that support only IPv4,
and an AF_INET6 listener on systems that can support IPv6. Incoming
IPv4 packets will be posted to an AF_INET6 listener with a mapped IPv4
address.

Max Matveev <makc@sgi.com> says:
  Creating a single listener can be dangerous - if net.ipv6.bindv6only
  is enabled then it's possible to create another listener in v4
  namespace on the same port and steal the traffic from the "unifed"
  listener. You need to disable V6ONLY explicitly via a sockopt to stop
  that.

Set appropriate socket option on RPC server listener sockets to prevent
this.

Subject: SUNRPC: Simplify rpcb_register() API

Bruce suggested there's no need to expose the difference between an error
sending the PMAP_SET request and an error reply from the portmapper to
rpcb_register's callers.  The user space equivalent of rpcb_register() is
pmap_set(3), which returns a bool_t : either the PMAP set worked, or it
didn't.  Simple.

So let's remove the "*okay" argument from rpcb_register() and
rpcb_v4_register(), and simply return an error if any part of the call
didn't work.

Subject: SUNRPC: Split portmap unregister API into separate function

Create a separate server-level interface for unregistering RPC services.

The mechanics of, and the API for, registering and unregistering RPC
services will diverge further as support for IPv6 is added.

Subject: SUNRPC: Support IPv6 when registering kernel RPC services

In order to advertise NFS-related services on IPv6 interfaces via
rpcbind, the kernel RPC server implementation must use
rpcb_v4_register() instead of rpcb_register().

A new kernel build option allows distributions to use the legacy
v2 call until they integrate an appropriate user-space rpcbind
daemon that can support IPv6 RPC services.

I tried adding some automatic logic to fall back if registering
with a v4 protocol request failed, but there are too many corner
cases.  So I just made it a compile-time switch that distributions
can throw when they've replaced portmapper with rpcbind.

Subject: lockd: address-family independent printable addresses

Knowing which source address is used for communicating with remote NLM
services can be helpful for debugging configuration problems on hosts
with multiple addresses.

Keep the dprintk debugging here, but adapt it so it displays AF_INET6
addresses properly.  There are also a couple of dprintk clean-ups as
well.

At some point we will aggregate the helpers that display presentation
format addresses into a single set of shared helpers.

Subject: lockd: Specify address family for source address

Make sure an address family is specified for source addresses passed to
nlm_lookup_host().  nlm_lookup_host() will need this when it becomes
capable of dealing with AF_INET6 addresses.

Subject: lockd: Use sockaddr_storage for h_saddr field

To store larger addresses in the nlm_host structure, make h_saddr a
sockaddr_storage.  And let's call it something more self-explanatory:
"saddr" could easily be mistaken for "server address".

"struct sockaddr_in *" arguments.

Subject: lockd: Support AF_INET6 when hashing addresses in nlm_lookup_host

Adopt an approach similar to the RPC server's auth cache (from Aurelien
Charbon and Brian Haley).

Note nlm_lookup_host()'s existing IP address hash function has the same
issue with correctness on little-endian systems as the original IPv4 auth
cache hash function, so I've also updated it with a hash function similar
to the new auth cache hash function.

Subject: SUNRPC: Register both netids for AF_INET6 servers

TI-RPC is a user-space library of RPC functions that replaces ONC RPC
and allows RPC to operate in the new world of IPv6.

TI-RPC combines the concept of a transport protocol (UDP and TCP)
and a protocol family (PF_INET and PF_INET6) into a single identifier
called a "netid."  For example, "udp" means UDP over IPv4, and "udp6"
means UDP over IPv6.

For rpcbind, then, the RPC service tuple that is registered and
advertised is:

  [RPC program, RPC version, service address and port, netid]

instead of

  [RPC program, RPC version, port, protocol]

Service address is typically ANYADDR, but can be a specific address
of one of the interfaces on a multi-homed host.  The third item in
the new tuple is expressed as a universal address.

The current Linux rpcbind implementation registers a netid for both
protocol families when RPCB_SET is done for just the PF_INET6 version
of the netid (ie udp6 or tcp6).  So registering "udp6" causes a
registration for "udp" to appear automatically as well.

We've recently determined that this is incorrect behavior.  In the
TI-RPC world, "udp6" is not meant to imply that the registered RPC
service handles requests from AF_INET as well, even if the listener
socket does address mapping.  "udp" and "udp6" are entirely separate
capabilities, and must be registered separately.

The Linux kernel, unlike TI-RPC, leverages address mapping to allow a
single listener socket to handle requests for both AF_INET and AF_INET6.
This is still OK, but the kernel currently assumes registering "udp6"
will cover "udp" as well.  It registers only "udp6" for it's AF_INET6
services, even though they handle both AF_INET and AF_INET6 on the same
port.

So svc_register() actually needs to register both "udp" and "udp6"
explicitly (and likewise for TCP).  Until rpcbind is fixed, the
kernel can ignore the return code for the second RPCB_SET call.

Please merge this with commit 15231312:

Subject: SUNRPC: Use short-hand IPv6 ANYADDR for RPCB_SET

Clean up: When doing an RPCB_SET, make the kernel's rpcb client use the
shorthand "::" for the universal form of the IPv6 ANY address.

Without this patch, rpcbind will advertise:

  0000:0000:0000:0000:0000:0000:0000:0000.x.y

This is cosmetic only.  It cleans up the display of information from
/sbin/rpcinfo.

Subject: SUNRPC: Fix up svc_unregister()

With the new rpcbind code, a PMAP_UNSET will not have any effect on
services registered via rpcbind v3 or v4.

Implement a version of svc_unregister() that uses an RPCB_UNSET with
an empty netid string to make sure we have cleared *all* entries for
a kernel RPC service when shutting down, or before starting a fresh
instance of the service.

Use the new version only when CONFIG_SUNRPC_REGISTER_V4 is enabled;
otherwise, the legacy PMAP version is used to ensure complete
backwards-compatibility with the Linux portmapper daemon.

Subject: SUNRPC: Clean up debug messages in rpcb_clnt.c

The RPCB XDR functions are used for multiple procedures.  For instance,
rpcb_encode_getaddr() is used for RPCB_GETADDR, RPCB_SET, and
RPCB_UNSET.  Make the XDR debug messages more generic so they are less
confusing.

And, unlike in other RPC consumers in the kernel, a single debug flag
enables all levels of debug messages in the RPC bind client, including
XDR debug messages.  Since the XDR decoders already report success or
failure in this case, remove redundant debug messages in the mid-level
rpcb_register_call() function.

Subject: nfsd: do_probe_callback should not clear rpc stats

Now that cb_stats are static (since commit
ff7d9756b501744540be65e172d27ee321d86103)
there's no need to clear them.

Initially I thought it might make sense to do
that every callback probing but since the stats
are per-program and they are shared between possibly
several client callback instances, zeroing them out
seems like the wrong thing to do.

Note that that commit also introduced a bug
since stats.program is also being cleared in the process
and it is not restored after the memset as it used to be.

Subject: nfsd: use nfs client rpc callback program

since commit ff7d9756b501744540be65e172d27ee321d86103
"nfsd: use static memory for callback program and stats"
do_probe_callback uses a static callback program
(NFS4_CALLBACK) rather than the one set in clp->cl_callback.cb_prog
as passed in by the client in setclientid (4.0)
or create_session (4.1).

This patches introduces rpc_create_args.prognumber that allows
overriding program->number when creating rpc_clnt.

Subject: ibm_newemac: Allow the "no flow control" EMAC feature to work

Some PowerPC 40x chips have errata that force us not to use the integrated
flow control.  We have the feature defined, but it currently can't be used
because it is never added to EMAC_FTRS_POSSIBLE.

This adds a Kconfig option for affected platforms to select and puts the
feature in the EMAC_FTRS_POSSIBLE list.  This is set for PowerPC 405EZ
platforms as well.

Subject: ibm_newemac: Introduce mal_has_feature

There are some PowerPC SoCs that do odd things with the MAL handling.  In
order to accommodate them, we need to introduce a feature mechanism that is
similar to the existing emac_has_feature function.

This adds a feature variable to the mal_instance structure, and adds a
mal_has_feature function.  Two features are defined and are guarded
by Kconfig options that are selected by the affected platforms.

MAL_FTR_CLEAR_ICINSTAT is used for platforms that need to clear the
interrupt bits in the ICINTSTAT SDR for txeob/rxeob.  This is common
on MAL implementations that have interrupt coalescing.

MAL_FTR_COMMON_ERR_INT is used for platforms that have SERR, TXDE,
and RXDE OR'd into a single interrupt bit.

Subject: ibm_newemac: MAL support for PowerPC 405EZ

The PowerPC 405EZ SoC has some differences in the interrupt layout and
handling for the MAL.  The SERR, TXDE, and RXDE interrupts are OR'd into
a single interrupt.  Also, due to the possibility for interrupt coalescing,
the TXEOB and RXEOB interrupts require an interrupt bit to be cleared in
the ICINTSTAT SDR.

This sets the proper MAL feature bits for 405EZ boards, and adds a common
shared handler for SERR, TXDE, and RXDE.  The defines for the ICINTSTAT DCR
are added to the proper header file as well.

This has been adapted from code originally written by Stefan Roese.

Subject: powerpc/math-emu: Use kernel generic math-emu code

The math emulation code is centered around a set of generic macros that
provide the core of the emulation that are shared by the various
architectures and other projects (like glibc).  Each arch implements its
own sfp-machine.h to specific various arch specific details.

For historic reasons that are now lost the powerpc math-emu code had
its own version of the common headers.  This moves us to using the
kernel generic version and thus getting fixes when those are updated.

Also cleaned up exception/error reporting from the FP emulation functions.

- * Basic four-word fraction declaration and manipulation.
- *
- * When adding quadword support for 32 bit machines, we need
- * to be a little careful as double multiply uses some of these
- * macros: (in op-2.h)
- * _FP_MUL_MEAT_2_wide() uses _FP_FRAC_DECL_4, _FP_FRAC_WORD_4,
- * _FP_FRAC_ADD_4, _FP_FRAC_SRS_4
- * _FP_MUL_MEAT_2_gmp() uses _FP_FRAC_SRS_4 (and should use
- * _FP_FRAC_DECL_4: it appears to be broken and is not used
- * anywhere anyway. )
- *
- * I've now fixed all the macros that were here from the sparc64 code.
- * [*none* of the shift macros were correct!] -- PMM 02/1998
- *
- * The only quadword stuff that remains to be coded is:
- * 1) the conversion to/from ints, which requires
- * that we check (in op-common.h) that the following do the right thing
- * for quadwords: _FP_TO_INT(Q,4,r,X,rsz,rsg), _FP_FROM_INT(Q,4,X,r,rs,rt)
- * 2) multiply, divide and sqrt, which require:
- * _FP_MUL_MEAT_4_*(R,X,Y), _FP_DIV_MEAT_4_*(R,X,Y), _FP_SQRT_MEAT_4(R,S,T,X,q),
- * This also needs _FP_MUL_MEAT_Q and _FP_DIV_MEAT_Q to be defined to
- * some suitable _FP_MUL_MEAT_4_* macros in sfp-machine.h.
- * [we're free to choose whatever FP_MUL_MEAT_4_* macros we need for
- * these; they are used nowhere else. ]

Subject: softirqs, debug: preemption check

if a preempt count leaks out of a softirq handler it can be very hard
to figure it out. Add a debug check for this.

Subject: powerpc/4xx: Allow 4xx PCI bridge to be disabled via device tree

This patch allows the 4xx (conventional) PCI bridge to be disabled
via the device tree. This is needed for 4xx PCI adapter hardware.

Use the PCI node's status property to disable the PCI bridge.

Subject: powerpc/44x: Add AMCC Arches eval board support

The Arches Evaluation board is based on the AMCC 460GT SoC chip.
This board is a dual processor board with each processor providing
independent resources for Rapid IO, Gigabit Ethernet, and serial
communications.  Each 460GT has it's own 512MB DDR2 memory, 32MB NOR FLASH,
UART, EEPROM and temperature sensor, along with a shared debug port.
The two 460GT's will communicate with each other via shared memory,
Gigabit Ethernet and x1 PCI-Express.

Subject: softirq, warning fix: correct a format to avoid a warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Last -tip gives this warning:

kernel/softirq.c: Dans la fonction «__do_softirq» :
kernel/softirq.c:216: attention : format «%ld» expects type «long int», but argument 2 has type «int»

This patch corrects the format type, and a small mistake in the "softirq" word.

Subject: nfsd: common grace period control

Rewrite grace period code to unify management of grace period across
lockd and nfsd.  The current code has lockd and nfsd cooperate to
compute a grace period which is satisfactory to them both, and then
individually enforce it.  This creates a slight race condition, since
the enforcement is not coordinated.  It's also more complicated than
necessary.

Here instead we have lockd and nfsd each inform common code when they
enter the grace period, and when they're ready to leave the grace
period, and allow normal locking only after both of them are ready to
leave.

We also expect the locks_start_grace()/locks_end_grace() interface here
to be simpler to build on for future cluster/high-availability work,
which may require (for example) putting individual filesystems into
grace, or enforcing grace periods across multiple cluster nodes.

Subject: lockd: move grace period checks to common code

Do all the grace period checks in svclock.c.  This simplifies the code a
bit, and will ease some later changes.

Subject: lockd: reject reclaims outside the grace period

The current lockd does not reject reclaims that arrive outside of the
grace period.

Accepting a reclaim means promising to the client that no conflicting
locks were granted since last it held the lock.  We can meet that
promise if we assume the only lockers are nfs clients, and that they are
sufficiently well-behaved to reclaim only locks that they held before,
and that only reclaim locks have been permitted so far.  Once we leave
the grace period (and start permitting non-reclaims), we can no longer
keep that promise.  So we must start rejecting reclaims at that point.

Subject: svcrdma: Add Fast Reg MR Data Types

Add data types to track Fast Reg Memory Regions. The core data type is
svc_rdma_fastreg_mr that associates a device MR with a host kva and page
list. A field is added to the WR context to keep track of the FRMR
used to map the local memory for an RPC.

An FRMR list and spin lock are added to the transport instance to keep
track of all FRMR allocated for the transport. Also added are device
capability flags to indicate what the memory registration
capabilities are for the underlying device and whether or not fast
memory registration is supported.

Subject: lockd: Adjust nlmclnt_lookup_host() signature to accomodate
 non-AF_INET

Pass a struct sockaddr * and a length to nlmclnt_lookup_host() to
accomodate non-AF_INET family addresses.

As a side benefit, eliminate the hostname_len argument, as the hostname
is always NUL-terminated.

Subject: lockd: Add helper to sanity check incoming NOTIFY requests

lockd accepts SM_NOTIFY calls only from a privileged process on the
local system.  If lockd uses an AF_INET6 listener, the sender's address
(ie the local rpc.statd) will be the IPv6 loopback address, not the
IPv4 loopback address.

Make sure the privilege test in nlmsvc_proc_sm_notify() and
nlm4svc_proc_sm_notify() works for both AF_INET and AF_INET6 family
addresses by refactoring the test into a helper and adding support for
IPv6 addresses.

Subject: lockd: Remove unused fields in the nlm_reboot structure

The nlm_reboot structure is used to store information provided by the
NSM_NOTIFY procedure.  This procedure is not specified by the NLM or NSM
protocols, other than to say that the procedure can be used to transmit
information private to a particular NLM/NSM implementation.

For Linux, the callback arguments include the name of the monitored host,
the new NSM state of the host, and a 16-byte private opaque.

As a clean up, remove the unused fields and the server-side XDR logic that
decodes them.

Subject: NLM: Always start both UDP and TCP listeners

Commit 24e36663, which first appeared in 2.6.19, changed lockd so that
the client side starts a UDP listener only if there is a UDP NFSv2/v3
mount.  Its description notes:

    This... means that lockd will *not* listen on UDP if the only
    mounts are TCP mount (and nfsd hasn't started).

    The latter is the only one that concerns me at all - I don't know
    if this might be a problem with some servers.

Unfortunately it is a problem for Linux itself.  The rpc.statd daemon
on Linux uses UDP for contacting the local lockd, no matter which
protocol is used for NFS mounts.  Without a local lockd UDP listener,
NFSv2/v3 lock recovery from Linux NFS clients always fails.

Revert parts of commit 24e36663 so lockd_up() always starts both
listeners.

From 1835f1d720786138c43147448f4527dd380c1e33 Mon Sep 17 00:00:00 2001

Subject: ARM: OMAP2: Move sleep.S into sleep24xx.S

Some register offsets are different for 242x and 243x. This
will allow compiling sleep code for both chips into the same
kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the
omap24xx_cpu_suspend instead of loading the values since the only.

Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL
instead of the address as that's what omap24xx_cpu_suspend expects to
determine between DDR and SDR. This bug has not been noticed as
the boards seem to have DDR instead of SDR.

Note that some PM patches are still missing. The PM patches will
be added later on once the base files are in sync with linux-omap
tree.

Subject: ARM: OMAP2: Misc updates from linux-omap tree

Misc updates from linux-omap tree, mostly to update common
device initialization and add missing defines from linux-omap
tree. Also some changes to make room for adding 34xx in
following patches.

Note that the I2C resources are now set up in
arch/arm/plat-omap/i2c.c helper, and can be removed
from devices.c.

Subject: svcrdma: Query device for Fast Reg support during connection setup

Query the device capabilities in the svc_rdma_accept function to determine
what advanced memory management capabilities are supported by the device.
Based on the query, select the most secure model available given the
requirements of the transport and capabilities of the adapter.

Subject: svcrdma: Modify post recv path to use local dma key

Update the svc_rdma_post_recv routine to use the adapter's global LKEY
instead of sc_phys_mr which is only valid when using a DMA MR.

Subject: svcrdma: Add support to svc_rdma_send to handle chained WR

WR can be submitted as linked lists of WR. Update the svc_rdma_send
routine to handle WR chains. This will be used to submit a WR that
uses an FRMR with another WR that invalidates the FRMR.

Subject: svcrdma: Modify the RPC recv path to use FRMR when available

RPCRDMA requests that specify a read-list are fetched with RDMA_READ. Using
an FRMR to map the data sink improves NFSRDMA security on transports that
place the RDMA_READ data sink LKEY on the wire because the valid lifetime
of the MR is only the duration of the RDMA_READ. The LKEY is invalidated
when the last RDMA_READ WR completes.

Mapping the data sink also allows for very large amounts to data to be
fetched with a single WR, so if the client is also using FRMR, the entire
RPC read-list can be fetched with a single WR.

Subject: svcrdma: Modify the RPC reply path to use FRMR when available

Use FRMR to map local RPC reply data. This allows RDMA_WRITE to send reply
data using a single WR. The FRMR is invalidated by linking the LOCAL_INV WR
to the RDMA_SEND message used to complete the reply.

Subject: svcrdma: Fix IRD/ORD polarity

The inititator/responder resources in the event have been swapped. They
no represent what the local peer would set their values to in order to
match the peer. Note that iWARP does not exchange these on the wire and
the provider is simply putting in the local device max.

Subject: NFS: Fix nfs_file_llseek()

After the BKL removal patches were applied to the rest of the NFS code, the
BKL protection in nfs_file_llseek() is no longer sufficient to ensure that
inode->i_size is read safely in generic_file_llseek_unlocked().

In order to fix the situation, we either have to replace the naked read of
inode->i_size in generic_file_llseek_unlocked() with i_size_read(), or the
whole thing needs to be executed under the inode->i_lock;
In order to avoid disrupting other filesystems, avoid touching
generic_file_llseek_unlocked() for now...

Subject: NFS: Clean up nfs_sb_active/nfs_sb_deactive

Instead of causing umount requests to block on server->active_wq while the
asynchronous sillyrename deletes are executing, we can use the sb->s_active
counter to obtain a reference to the super_block, and then release that
reference in nfs_async_unlink_release().

Subject: powerpc: Avoid integer overflow in page_is_ram()

Commit 8b150478 ("ppc: make phys_mem_access_prot() work with pfns
instead of addresses") fixed page_is_ram() in arch/ppc to avoid overflow
for addresses above 4G on 32-bit kernels.  However arch/powerpc's
page_is_ram() is missing the same fix -- it computes a physical address
by doing pfn << PAGE_SHIFT, which overflows if pfn corresponds to a page
above 4G.

In particular this causes pages above 4G to be mapped with the wrong
caching attribute; for example many ppc440-based SoCs have PCI space
above 4G, and mmap()ing MMIO space may end up with a mapping that has
caching enabled.

Fix this by working with the pfn and avoiding the conversion to
physical address that causes the overflow.  This patch compares the
pfn to max_pfn, which is a semantic change from the old code -- that
code compared the physical address to high_memory, which corresponds
to max_low_pfn.  However, I think that was is another bug, since
highmem pages are still RAM.

-                 Information about /proc/ppc_htab
-=====================================================================
-
-This document and the related code was written by me (Cort Dougan), please
-email me (cort@fsmlabs.com) if you have questions, comments or corrections.
-
-Last Change: 2.16.98
-
-This entry in the proc directory is readable by all users but only
-writable by root.
-
-The ppc_htab interface is a user level way of accessing the
-performance monitoring registers as well as providing information
-about the PTE hash table.
-
-1. Reading
-
-  Reading this file will give you information about the memory management
-  hash table that serves as an extended tlb for page translation on the
-  powerpc.  It will also give you information about performance measurement
-  specific to the cpu that you are using.
-
-  Explanation of the 604 Performance Monitoring Fields:
-    MMCR0 - the current value of the MMCR0 register
-    PMC1
-    PMC2 - the value of the performance counters and a
-           description of what events they are counting
-           which are based on MMCR0 bit settings.
-  Explanation of the PTE Hash Table fields:
-
-    Size - hash table size in Kb.
-    Buckets -  number of buckets in the table.
-    Address - the virtual kernel address of the hash table base.
-    Entries - the number of ptes that can be stored in the hash table.
-    User/Kernel - how many pte's are in use by the kernel or user at that time.
-    Overflows - How many of the entries are in their secondary hash location.
-    Percent full - ratio of free pte entries to in use entries.
-    Reloads - Count of how many hash table misses have occurred
-              that were fixed with a reload from the linux tables.
-              Should always be 0 on 603 based machines.
-    Non-error Misses - Count of how many hash table misses have occurred
-              that were completed with the creation of a pte in the linux
-              tables with a call to do_page_fault().
-    Error Misses - Number of misses due to errors such as bad address
-              and permission violations.  This includes kernel access of
-              bad user addresses that are fixed up by the trap handler.
-
-  Note that calculation of the data displayed from /proc/ppc_htab takes
-  a long time and spends a great deal of time in the kernel.  It would
-  be quite hard on performance to read this file constantly.  In time
-  there may be a counter in the kernel that allows successive reads from
-  this file only after a given amount of time has passed to reduce the
-  possibility of a user slowing the system by reading this file.
-
-2. Writing
-
-  Writing to the ppc_htab allows you to change the characteristics of
-  the powerpc PTE hash table and setup performance monitoring.
-
-  Resizing the PTE hash table is not enabled right now due to many
-  complications with moving the hash table, rehashing the entries
-  and many many SMP issues that would have to be dealt with.
-
-  Write options to ppc_htab:
-  
-   - To set the size of the hash table to 64Kb:
-
-      echo 'size 64' > /proc/ppc_htab
-
-     The size must be a multiple of 64 and must be greater than or equal to
-     64.
-
-   - To turn off performance monitoring:
-
-      echo 'off' > /proc/ppc_htab
-
-   - To reset the counters without changing what they're counting:
-
-      echo 'reset' > /proc/ppc_htab
-
-     Note that counting will continue after the reset if it is enabled.
-
-   - To count only events in user mode or only in kernel mode:
-
-      echo 'user' > /proc/ppc_htab
-       ...or...
-      echo 'kernel' > /proc/ppc_htab
-
-     Note that these two options are exclusive of one another and the
-     lack of either of these options counts user and kernel.
-     Using 'reset' and 'off' reset these flags.
-
-   - The 604 has 2 performance counters which can each count events from
-     a specific set of events.  These sets are disjoint so it is not
-     possible to count _any_ combination of 2 events.  One event can
-     be counted by PMC1 and one by PMC2.
-
-     To start counting a particular event use:
-
-      echo 'event' > /proc/ppc_htab
-
-     and choose from these events:
-
-     PMC1
-     ----
-      'ic miss' - instruction cache misses
-      'dtlb' - data tlb misses (not hash table misses)
-
-     PMC2
-     ----
-      'dc miss' - data cache misses
-      'itlb' - instruction tlb misses (not hash table misses)
-      'load miss time' - cycles to complete a load miss
-
-3. Bugs
-
-  The PMC1 and PMC2 counters can overflow and give no indication of that
-  in /proc/ppc_htab.

-    The code makes the assumption of only two processors.  The changes
-    necessary to work with any number would not be overly difficult but
-    I don't have any machines with >2 processors so it's not high on my
-    list of priorities.  If anyone else would like do to the work email
-    me and I can point out the places that need changed.  If you have >2
-    processors and don't want to add support yourself let me know and I
-    can take a look into it.
-
-  BeBox
-    BeBox support hasn't been added to the 2.1.X kernels from 2.0.X
-    but work is being done and SMP support for BeBox is in the works.
-
-  CHRP
-    CHRP SMP works and is fairly solid.  It's been tested on the IBM F50
-    with 4 processors for quite some time now.

Subject: powerpc: Enforce sane MAX_ORDER

powerpc uses CONFIG_FORCE_MAX_ZONEORDER, and some things depend on it
being at least 10 when 64k pages are not configured (notably the dart
iommu code with CONFIG_PM). The defaults are fine, but when going from a
64K pages config to one without 64K pages, MAX_ORDER stays at 9 which is
too low for 4K pages.

This patch makes the Kconfig enforce at least the defaults.

Subject: powerpc: Honor O_NONBLOCK flag when reading RTAS log

rtas_log_read() doesn't check file flags for O_NONBLOCK and blocks
non-blocking readers of /proc/ppc64/rtas/error_log when there is
no data available. This fixes it.

Also rtas_log_read() returns now with ENODATA to prevent suspending of
process in wait_event_interruptible() when logging facility was
switched off and log is already empty.

Subject: powerpc: Fix sysfs pci mmap on 32-bit machines with 64-bit PCI

When manipulating 64-bit PCI addresses, the code would lose the
top 32-bit in a couple of places when shifting a pfn due to missing
type casting from the 32-bit pfn to a 64-bit resource before the
shift.

This breaks using newer X servers for example on 440 machines
with the PCI bus above 32-bit.

+	  If an exception is caused while executing code within the exception
+	  handler, the NMI handler, the reset vector, or in emulator mode,
+	  a double fault occurs. On the Blackfin, this is a unrecoverable
+	  event. You have two options:
+	  - RESET exactly when double fault occurs. The excepting
+	    instruction address is stored in RETX, where the next kernel
+	    boot will print it out.
+	  - Print debug message. This is much more error prone, although
+	    easier to handle. It is error prone since:
+	    - The excepting instruction is not committed.
+	    - All writebacks from the instruction are prevented.
+	    - The generated exception is not taken.
+	    - The EXCAUSE field is updated with an unrecoverable event
+	    The only way to check this is to see if EXCAUSE contains the
+	    unrecoverable event value at every exception return. By selecting
+	    this option, you are skipping over the faulting instruction, and 
+	    hoping things stay together enough to print out a debug message.
+
+	  This does add a little kernel code, but is the only method to debug
+	  double faults - if unsure say "Y"

Subject: Blackfin arch: fixing bug - under IRQ stress, running applications
 may wrongly trigger an ICPLB miss and be killed

Disable IRQs while frobbing the CPLB registers, to avoid accessing the
data in current_rwx_mask while it isn't covered by CPLBs.

Subject: NFS: Add options for finer control of the lookup cache

Add the flag NFS_MOUNT_LOOKUP_CACHE_NONEG to turn off the caching of
negative dentries. In reality what we do is to force
nfs_lookup_revalidate() to always discard negative dentries.

Add the flag NFS_MOUNT_LOOKUP_CACHE_NONE for enforcing stricter
revalidation of dentries. It forces the revalidate code to always do a
lookup instead of just checking the cached mtime of the parent directory.

Subject: NFS: Don't apply NFS_MOUNT_FLAGMASK to text-based mounts

The point of introducing text-based mounts was to allow us to add
functionality without having to worry about legacy binary mount formats.
The mask should be there in order to ensure that binary formats don't start
enabling features that they cannot support. There is no justification for
applying it to the text mount path.

Subject: NFS: Add mount options for controlling the lookup cache

Add the following NFS-specific mount options to the parser.

    -o lookupcache=all          /* Default: cache positive & negative
                                   dentries */
    -o lookupcache=pos[itive]   /* Don't cache negative dentries */
    -o lookupcache=none         /* Strict revalidation of all dentries */

Subject: [ARM] S3C24XX: Move files out of include/asm-arm/plat-s3c*

First move of items out of include/asm-arm/plat-s3c* to their
new homes under arch/arm/plat-s3c/include/plat and
arch/arm/plat-s3c24xx/include/plat directories.

Note, we have to create a dummy arch/arm/plat-s3c/Makefile to
allow us to add arch/arm/plat-s3c/include/plat to the path.

Try to avoid taking and dropping the inode->i_lock more than once. Do so by
moving the code in nfs_refresh_inode() that needs to be done under the
spinlock into a function nfs_refresh_inode_locked(), and then having both
nfs_refresh_inode() and nfs_post_op_update_inode() call it directly.

Subject: NFS: Fix the NFS attribute update

Currently nfs_refresh_inode() will only update the inode metadata if it
sees that the RPC call that returned the nfs_fattr was started
after the last update of the inode. This means that if we have parallel
RPC calls to the same inode (when sending WRITE calls, for instance), we
may often miss updates.

This patch attempts to recover those missed updates by also accepting
them if the ctime in the nfs_fattr is more recent than the inode's
cached ctime.
It also recovers the case where the file size has increased, but the
ctime has not been updated due to limited ctime resolution.

Subject: NFS: Fix nfs_post_op_update_inode_force_wcc()

If we believe that the attributes are old (see nfs_refresh_inode()), then
we shouldn't force an update.
Also ensure that we hold the inode->i_lock across attribute checks and the
call to nfs_refresh_inode_locked() to ensure that we don't race with other
attribute updates.

Subject: NFS: Convert __nfs_revalidate_inode() to use nfs_refresh_inode()

In the case where there are parallel RPC calls to the same inode, we may
receive stale metadata due to the lack of ordering, hence the sanity
checking of metadata in nfs_refresh_inode().
Currently, __nfs_revalidate_inode() is calling nfs_update_inode() directly,
without any further sanity checks, and hence may end up setting the inode
up with stale metadata.

Fix is to use nfs_refresh_inode() instead of nfs_update_inode().

Subject: NFS: Don't clear nfsi->cache_validity in nfs_check_inode_attributes()

If we're merely checking the inode attributes because we suspect that the
'updated' attributes returned by the RPC call are stale, then we shouldn't
be doing weak cache consistency updates or clearing the cache_validity
flags.

Currently, if two processes are both trying to revalidate metadata for the
same inode, they will find themselves being serialised. There is no good
justification for this now that we have improved our ability to detect
stale attribute data, so we should remove that serialisation.

Subject: nfs: BUG_ON in nfs_follow_mountpoint

Unfortunately, BUG_ON(IS_ROOT(dentry)) can happen inside
nfs_follow_mountpoint with NFS running Fedora 8 using a
specific setup.
https://bugzilla.redhat.com/show_bug.cgi?id=458622

So, the situation should be handled on NFS client gracefully.

Subject: NFS: missing nfs_fattr_init in nfs3_proc_getacl and nfs3_proc_setacls
 (resend #2)

The fattrs used in the NFSv3 getacl/setacl calls are not being properly
initialized. This occasionally causes nfs_update_inode to fall into
NFSv4 specific codepaths when handling post-op attrs from these calls.

Thanks to Cai Qian for noticing the spurious NFSv4 messages in debug
output from a v3 mount...

Subject: nfs: authenticated deep mounting

Allow mount to do authenticated mounts below the root of the exported tree.
The wording in RFC 2623, sec 2.3.2. allows fsinfo with UNIX authentication
on the root of the export. Mounts are not always done on the root
of the exported tree. Especially autoumounts often mount below the root of
the exported tree.
Some server implementations (justly) require full authentication for the
so-called deep mounts. The old code used AUTH_SYS only. This caused deep
mounts to fail on systems requiring stronger authentication..
The client should try both authentication types and use the first one that
succeeds.
This method was already partially implemented. This patch completes
the implementation for NFS2 and NFS3.
This patch was developed to allow Debian systems to automount home directories
on Solaris servers with krb5 authentication.

Tested on kernel 2.6.24-etchnhalf.1

remove 8 bytes of padding from struct nfs_fattr on 64 bit builds

This also removes padding from several nfs structures, including
16 bytes from  nfs4_opendata, nfs4_createdata,nfs3_createdata
& 8 bytes from nfs_read_data,nfs_write_data,nfs_removeres,nfs4_closedata

This also reduces the reported stack usage of many nfs functions (30+).

This patch is against the latest git 2.6.27-rc4.
I've built & run this on my AMD64 desktop, & successfully run _simple_
tests with a  64 bit client => 32 bit server & 32 bit client to 64 bit
server.

On fedora with gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8) checkpatch
reports 33 functions with reduced stack usage.
e.g.
__nfs_revalidate_inode [nfs] 216 => 200
_nfs4_proc_access [nfs] 304 => 288
_nfs4_proc_link [nfs] 536 => 504
_nfs4_proc_remove [nfs] 304 => 288
_nfs4_proc_rename [nfs] 584 => 552
nfs3_proc_access [nfs] 272 => 256
nfs3_proc_getacl [nfs] 384 => 368
nfs3_proc_link [nfs] 496 => 464
etc
I can supply the complete list if anyone is interested.

Subject: NFS: SETCLIENTID truncates client ID and netid

The sc_name field is currently 56 bytes long.  This is not large enough
to hold a pair of IPv6 addresses, the authentication type, the protocol
name, and a uniquifier number.  The maximum possible size of the name
string using IPv6 addresses is just under 110 bytes, so I increased the
size of the sc_name field to accomodate this maximum.

In addition, the strings in the nfs4_setclientid structure are
constructed with scnprintf(), which wants to terminate its output with
'\0'.  The sc_netid field was large enough only for a three byte netid
string and a '\0' so inet6 netids were being truncated.  Perhaps we
don't need the overhead of scnprintf() to do a simple string copy, but
I fixed this by increasing the size of the buffer by one byte.

Since all three of the string buffers in nfs4_setclientid are
constructed with scnprintf(), I increased the size of all three by one
byte to document the requirement, although I don't think either the
universal address field or the name field will be so small that these
strings get truncated in this way.

The size of the Linux client's client ID on the wire will be larger
than before.  RFC 3530 suggests the size limit for client IDs is 1024,
and we are still well below that.

Subject: SUNRPC: Fix autobind on cloned rpc clients

Despite the fact that cloned rpc clients won't have the cl_autobind flag
set, they may still find themselves calling rpcb_getport_async(). For this
to happen, it suffices for a _parent_ rpc_clnt to use autobinding, in which
case any clone may find itself triggering the !xprt_bound() case in
call_bind().

The correct fix for this is to walk back up the tree of cloned rpc clients,
in order to find the parent that 'owns' the transport, either because it
has clnt->cl_autobind set, or because it originally created the
transport...

Subject: NFS: Client mounts hang when exported directory do not exist

This patch fixes a regression that was introduced by the string based mounts.

nfs_mount() statically returns -EACCES for every error returned
by the remote mounted. This is incorrect because -EACCES is
an non-fatal error to the mount.nfs command. This error causes
mount.nfs to retry the mount even in the case when the exported
directory does not exist.

This patch maps the errors returned by the remote mountd into
valid errno values, exactly how it was done pre-string based
mounts. By returning the correct errno enables mount.nfs
to do the right thing.

Subject: sunrpc: fix oops in rpc_create when the mount namespace is unshared

On a system with nfs mounts, if a task unshares its mount namespace,
a oops can occur when the system is rebooted if the task is the last
to unreference the nfs mount. It will try to create a rpc request
using utsname() which has been invalidated by free_nsproxy().

The patch fixes the issue by using the global init_utsname() which is
always valid. the capability of identifying rpc clients per uts namespace
stills needs some extra work so this should not be a problem.

-			A Simple Guide to Configure KGDB
-
-			Sonic Zhang <sonic.zhang@analog.com>
-				Aug. 24th 2006
-
-
-This KGDB patch enables the kernel developer to do source level debugging on
-the kernel for the Blackfin architecture.  The debugging works over either the
-ethernet interface or one of the uarts.  Both software breakpoints and
-hardware breakpoints are supported in this version.
-http://docs.blackfin.uclinux.org/doku.php?id=kgdb
-
-
-2 known issues:
-1. This bug:
-       http://blackfin.uclinux.org/tracker/index.php?func=detail&aid=544&group_id=18&atid=145
-   The GDB client for Blackfin uClinux causes incorrect values of local
-   variables to be displayed when the user breaks the running of kernel in GDB.
-2. Because of a hardware bug in Blackfin 533 v1.0.3:
-       05000067 - Watchpoints (Hardware Breakpoints) are not supported
-   Hardware breakpoints cannot be set properly.
-
-
-Debug over Ethernet:
- 
-1. Compile and install the cross platform version of gdb for blackfin, which
-   can be found at $(BINROOT)/bfin-elf-gdb.
-
-2. Apply this patch to the 2.6.x kernel.  Select the menuconfig option under
-   "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
-   With this selected, option "Full Symbolic/Source Debugging support" and 
-   "Compile the kernel with frame pointers" are also selected.
-
-3. Select option "KGDB: connect over (Ethernet)".  Add "kgdboe=@target-IP/,@host-IP/" to
-   the option "Compiled-in Kernel Boot Parameter" under "Kernel hacking".
-
-4. Connect minicom to the serial port and boot the kernel image.
-
-5. Configure the IP "/> ifconfig eth0 target-IP"
-
-6. Start GDB client "bfin-elf-gdb vmlinux".
-
-7. Connect to the target "(gdb) target remote udp:target-IP:6443".
-
-8. Set software breakpoint "(gdb) break sys_open".
-
-9. Continue "(gdb) c".
-
-10. Run ls in the target console "/> ls".
-
-11. Breakpoint hits. "Breakpoint 1: sys_open(..."
-
-12. Display local variables and function paramters.
-    (*) This operation gives wrong results, see known issue 1.
-
-13. Single stepping "(gdb) si".
-
-14. Remove breakpoint 1. "(gdb) del 1"
-
-15. Set hardware breakpoint "(gdb) hbreak sys_open".
-
-16. Continue "(gdb) c".
-
-17. Run ls in the target console "/> ls".
-
-18. Hardware breakpoint hits. "Breakpoint 1: sys_open(...".
-    (*) This hardware breakpoint will not be hit, see known issue 2.
-
-19. Continue "(gdb) c".
-
-20. Interrupt the target in GDB "Ctrl+C".
-
-21. Detach from the target "(gdb) detach".
-
-22. Exit GDB "(gdb) quit".
-
-
-Debug over the UART:
-
-1. Compile and install the cross platform version of gdb for blackfin, which
-   can be found at $(BINROOT)/bfin-elf-gdb.
-
-2. Apply this patch to the 2.6.x kernel.  Select the menuconfig option under
-   "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
-   With this selected, option "Full Symbolic/Source Debugging support" and 
-   "Compile the kernel with frame pointers" are also selected.
-
-3. Select option "KGDB: connect over (UART)".  Set "KGDB: UART port number" to be
-   a different one from the console.  Don't forget to change the mode of
-   blackfin serial driver to PIO.  Otherwise kgdb works incorrectly on UART.
- 
-4. If you want connect to kgdb when the kernel boots, enable
-   "KGDB: Wait for gdb connection early" 
-
-5. Compile kernel.
-
-6. Connect minicom to the serial port of the console and boot the kernel image.
-
-7. Start GDB client "bfin-elf-gdb vmlinux".
-
-8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
-
-9. Connect to the target on the second serial port "(gdb) target remote /dev/ttyS1".
-
-10. Set software breakpoint "(gdb) break sys_open".
-
-11. Continue "(gdb) c". 
-
-12. Run ls in the target console "/> ls". 
-
-13. A breakpoint is hit. "Breakpoint 1: sys_open(..."
-
-14. All other operations are the same as that in KGDB over Ethernet. 
-
-
-Debug over the same UART as console:
-
-1. Compile and install the cross platform version of gdb for blackfin, which
-   can be found at $(BINROOT)/bfin-elf-gdb.
-
-2. Apply this patch to the 2.6.x kernel.  Select the menuconfig option under
-   "Kernel hacking" -> "Kernel debugging" -> "KGDB: kernel debug with remote gdb".
-   With this selected, option "Full Symbolic/Source Debugging support" and 
-   "Compile the kernel with frame pointers" are also selected.
-
-3. Select option "KGDB: connect over UART".  Set "KGDB: UART port number" to console.
-   Don't forget to change the mode of blackfin serial driver to PIO.
-   Otherwise kgdb works incorrectly on UART.
- 
-4. If you want connect to kgdb when the kernel boots, enable
-   "KGDB: Wait for gdb connection early" 
-
-5. Connect minicom to the serial port and boot the kernel image. 
-
-6. (Optional) Ask target to wait for gdb connection by entering Ctrl+A. In minicom, you should enter Ctrl+A+A.
-
-7. Start GDB client "bfin-elf-gdb vmlinux".
-
-8. Set the baud rate in GDB "(gdb) set remotebaud 57600".
-
-9. Connect to the target "(gdb) target remote /dev/ttyS0".
-
-10. Set software breakpoint "(gdb) break sys_open".
-
-11. Continue "(gdb) c". Then enter Ctrl+C twice to stop GDB connection.
-
-12. Run ls in the target console "/> ls". Dummy string can be seen on the console.
-
-13. Then connect the gdb to target again. "(gdb) target remote /dev/ttyS0".
-    Now you will find a breakpoint is hit. "Breakpoint 1: sys_open(..."
-
-14. All other operations are the same as that in KGDB over Ethernet.  The only
-    difference is that after continue command in GDB, please stop GDB
-    connection by 2 "Ctrl+C"s and connect again after breakpoints are hit or
-    Ctrl+A is entered.

Subject: Blackfin arch: Better error handling of unknown exceptions

Better error handling of unknown exceptions, allows userspace to do a
EXCPT n instruction for a not installed exception handler, and the
kernel doesn't crash (like it use to before this).

Subject: Fix sections for omap-mcbsp platform driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Don't use __init but __devinit to define probe function.  A pointer to
omap_mcbsp_probe is passed to the core via platform_driver_register and
so the function must not disappear when the init code is freed.  Using
__init and having HOTPLUG=y the following probably oopses:

	echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/unbind
	echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/bind

While at it move the remove function to the .devexit.text section.

Subject: ARM: OMAP: Allocate McBSP devices dynamically

Based on Chandra's earlier patches in linux-omap tree.

Note that omap1_mcbsp_check and omap2_mcbsp_check are no longer
needed as there's now omap_mcbsp_check_valid_id() defined.

Also some functions can now be marked __init.

Subject: ARM: OMAP: Fixes to omap_mcbsp_request function

Bootloader may let McBSP logic running so make sure that block is idle
before requesting IRQs. Also make sure that TX and RX waitqueues are
initialized before request_irq.

Subject: Blackfin arch: rename blackfin_sram.c to sram-alloc.c

rename blackfin_sram.c to sram-alloc.c (we know it is a blackfin file,
since it is in arch/blackfin) - and there is no "driver" code in there,
it is just an allocator/deallocator for L1 and L2 sram.

Also fix a problem that checkpatch pointed out

Subject: powerpc/mpc5200: fix build warnings on mpc52xx_psc_spi driver

The register definitions have been changed for the mpc5200 PSC ports
to cover some of the changes in the mpc5200b.  One change is that the
ccr register is now a u32 instead of a u16.  However, for the purposes
of this driver we want to continue to use 16 bit access to avoid
changing the existing (working) behaviour.

This patch allows the driver to continue to do 16 bit accesses without
the compiler complaining about it.

Subject: i2c-mpc: suppress I2C device probing

This patch suppresses I2C device probing by clearing the class field
of the "struct i2c_adapter" for the MPC I2C bus adapters. Some board
configurations which rely on probing must be fixed up by adding a
proper I2C device node to the DTS file, like the TQM85xx modules.

Subject: OF: add fsl,mcu-mpc8349emitx to the exception list

of/base.c matches on the first (most specific) entries, which isn't
quite practical but it was discussed[1] that this won't change.

The bindings specifies verbose information for the devices, but
it doesn't fit in the I2C ID's 20 characters limit. The limit won't
change[2], and the bindings won't change either as they're correct.

So we have to put an exception for the MPC8349E-mITX-compatible
MCUs.

Subject: Input: ads7846 - fix cache line sharing issue

We had a report a while back that the ads7846 driver had some issues
when used with DMA-based SPI controllers (like atmel_spi) on systems
where main memory is not DMA-coherent (most non-x86 boards). Allocate
memory potentially used for DMA separately to avoid cache line issues.

Subject: Blackfin arch: Fix bug - HW Errors never recover on BF548

The kernel does not properly clear the EBIU Error Master (EBIU_ERRMST) Register
on BF548, which causes the kernel to panic.

We need to make sure that we clear the EBIU_ERRMST (necessary on BF54x)

Subject: ARM: OMAP2: Fix sparse, checkpatch warnings in OMAP2/3 IRQ code

Fix sparse warnings in mach-omap2/irq.c. Fix by defining
intc_bank_write_reg() and intc_bank_read_reg(), and convert INTC module
register access to use them rather than __raw_{read,write}l.

Also clear up some checkpatch warnings involving includes from asm/
rather than linux/.

From cc26b3b01bc96a8b8c36671b0dc4898b2a152ea8 Mon Sep 17 00:00:00 2001
From: "Syed Mohammed, Khasim" <khasim@ti.com>
Date: Thu, 9 Oct 2008 17:51:41 +0300
Subject: ARM: OMAP3: Add minimal omap3430 support

Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.

Also do following changes that make 34xx support usable:

- Remove unused sram.c functions for 34xx

- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
  in entry-macro.S

- Update mach-omap2/io.c to support 2420, 2430, and 34xx

- Also merge in 34xx GPMC changes to add fields wr_access and
  wr_data_mux_bus from Adrian Hunter

- Remove memory initialization call omap2_init_memory() until
  until more generic memory initialization patches are posted.
  It's OK to rely on bootloader initialization until then.

Subject: NFS: Fix attribute updates

This fixes a regression seen when running the Connectathon testsuite
against an ext3 filesystem. The reason was that the inode was constantly
being marked as 'just updated' by the jiffy wraparound test.
This again meant that newer GETATTR calls were failing to pass the
nfs_inode_attrs_need_update() test unless the changes caused a ctime update
on the server, since they were perceived as having been started before the
latest inode update.

Given that nfs_inode_attrs_need_update() already checks for wraparound
of nfsi->last_updated, we can drop the buggy "protection" in
nfs_update_inode().

Also make a slight micro-optimisation of nfs_inode_attrs_need_update(): we
are more often going to see time_after(fattr->time_start, nfsi->last_updated)
be true, rather than seeing an update of ctime/size, so put that test
first to ensure that we optimise away the ctime/size tests.

Subject: powerpc/spufs: set nlink count for spufs root correctly

Currently, an empty spufs root inode has nlink count of 1. However,
the directory has two links; / -> spu and /spu/ -> .

This change increments the link count of the root inode in spufs.

Subject: powerpc/spufs: add a missing mutex_unlock

A mutex_unlock(&gang->aff_mutex) in spufs_create_context() is missing
in case spufs_context_open() fails.  As a result, spu_create syscall
and spu_get_idle() may block.

This patch adds the mutex_unlock.

Subject: proc: fix return value of proc_reg_open() in "too late" case

If ->open() wasn't called, returning 0 is misleading and, theoretically,
oopsable:
1) remove_proc_entry clears ->proc_fops, drops lock,
2) ->open "succeeds",
3) ->release oopses, because it assumes ->open was called (single_release()).

Subject: [PATCH] signal, procfs: some lock_task_sighand() users do not need
 rcu_read_lock()

lock_task_sighand() make sure task->sighand is being protected,
so we do not need rcu_read_lock().
[ exec() will get task->sighand->siglock before change task->sighand! ]

But code using rcu_read_lock() _just_ to protect lock_task_sighand()
only appear in procfs. (and some code in procfs use lock_task_sighand()
without such redundant protection.)

Other subsystem may put lock_task_sighand() into rcu_read_lock()
critical region, but these rcu_read_lock() are used for protecting
"for_each_process()", "find_task_by_vpid()" etc. , not for protecting
lock_task_sighand().

Subject: powerpc: Oops in pseries_lmb_remove()

Testing hotplug memory remove has revealed that we can oops in
pseries_lmb_remove().  The incorrect shift causes a NULL pointer
dereference in the page_zone() inline routine.

I have only been able to reproduce the oops on kernels with large pages
enabled.

Tested on Power5 and Power6 with and without large pages enabled.

Subject: powerpc: Fix no interrupt handling in pata_of_platform

When no interrupt is specified the pata_of_platform fills the irq_res
resource with -1, which is wrong to do for two reasons:

1. By definition, 'no irq' should be IRQ 0, not some negative integer;
2. pata_platform checks for irq_res.start > 0, but since irq_res.start
   is unsigned type, the check will be true for `-1'.

Offset is unsigned and when an address isn't found in the vma map
vma_map_lookup() returns the vma physical address + 0x10000000.

vma_map_lookup used to return 0xffffffff on a failed lookup, but
a change was made to return the vma physical address + 0x10000000
There are two callers of vam_map_lookup: one of them correctly
deals with this new return value, but the other (below) did not.

Subject: powerpc: Fix error path in kernel_thread function

The powerpc 32-bit and 64-bit kernel_thread functions don't properly
propagate errors being returned by the clone syscall.  (In the case of
error, the syscall exit code returns a positive errno in r3 and sets
the CR0[SO] bit.)

This patch fixes that by negating r3 if CR0[SO] is set after the syscall.

Compatible property values in the form linux,<modalias> is not documented
anywhere and using it leaks Linux implementation details into the device
tree data (which is bad).  Remove support for compatible values of this
form.

If any platforms exist which depended on this code (and I don't know of
any), then they can be fixed up by adding legacy translations to the
lookup table in this file.

Subject: powerpc: Sync RPA note in zImage with kernel's RPA note

Commit 9b09c6d909dfd8de96b99b9b9c808b94b0a71614 ("powerpc: Change the
default link address for pSeries zImage kernels") changed the
real-base value in the CHRP note added by the addnote program from
12MB to 32MB to give more space for Open Firmware to load the zImage.
(The real-base value says where we want OF to position itself in
memory.)  However, this change was ineffective on most pSeries
machines, because the RPA note added by addnote has the "ignore me"
flag set to 1.  This was intended to tell OF to ignore just the RPA
note, but has the side effect of also making OF ignore the CHRP note
(at least on most pSeries machines).

To solve this we have to set the "ignore me" flag to 0 in the RPA
note.  (We can't just omit the RPA note because that is equivalent to
having an RPA note with default values, and the default values are not
what we want.)  However, then we have to make sure the values in the
zImage's RPA note match up with the values that the kernel supplies
later in prom_init.c with either the ibm,client-architecture-support
call or the process-elf-header call in prom_send_capabilities().

So this sets the "ignore me" flag in the RPA note in addnote to 0, and
adjusts the RPA note values in addnote.c and in prom_init.c to be
consistent with each other and with the values in ibm_architecture_vec.

However, since the wrapper is independent of the kernel, this doesn't
ensure that the notes will stay consistent.  To ensure that, this adds
code to addnote.c so that it can extract the kernel's RPA note from
the kernel binary and put that in the zImage.  To that end, we put the
kernel's fake ELF header (which contains the kernel's RPA note) into
its own section, and arrange for wrapper to pull out that section with
objcopy and pass it to addnote, which then extracts the RPA note from
it and transfers it to the zImage.

Subject: powerpc: Reserve in bootmem lmb reserved regions that cross NUMA
 nodes

If there are multiple reserved memory blocks via lmb_reserve() that are
contiguous addresses and on different NUMA nodes we are losing track of which
address ranges to reserve in bootmem on which node.  I discovered this
when I recently got to try 16GB huge pages on a system with more then 2 nodes.

When scanning the device tree in early boot we call lmb_reserve() with
the addresses of the 16G pages that we find so that the memory doesn't
get used for something else.  For example the addresses for the pages
could be 4000000000, 4400000000, 4800000000, 4C00000000, etc - 8 pages,
one on each of eight nodes.  In the lmb after all the pages have been
reserved it will look something like the following:

lmb_dump_all:
    memory.cnt            = 0x2
    memory.size           = 0x3e80000000
    memory.region[0x0].base       = 0x0
                      .size     = 0x1e80000000
    memory.region[0x1].base       = 0x4000000000
                      .size     = 0x2000000000
    reserved.cnt          = 0x5
    reserved.size         = 0x3e80000000
    reserved.region[0x0].base       = 0x0
                      .size     = 0x7b5000
    reserved.region[0x1].base       = 0x2a00000
                      .size     = 0x78c000
    reserved.region[0x2].base       = 0x328c000
                      .size     = 0x43000
    reserved.region[0x3].base       = 0xf4e8000
                      .size     = 0xb18000
    reserved.region[0x4].base       = 0x4000000000
                      .size     = 0x2000000000

The reserved.region[0x4] contains the 16G pages.  In
arch/powerpc/mm/num.c: do_init_bootmem() we loop through each of the
node numbers looking for the reserved regions that belong to the
particular node.  It is not able to identify region 0x4 as being a part
of each of the 8 nodes.  It is assuming that a reserved region is only
on a single node.

This patch takes out the reserved region loop from inside
the loop that goes over each node.  It looks up the active region containing
the start of the reserved region.  If it extends past that active region then
it adjusts the size and gets the next active region containing it.

Subject: sched_clock: prevent scd->clock from moving backwards

When sched_clock_cpu() couples the clocks between two cpus, it may
increment scd->clock beyond the GTOD tick window that __update_sched_clock()
uses to clamp the clock.  A later call to __update_sched_clock() may move
the clock back to scd->tick_gtod + TICK_NSEC, violating the clock's
monotonic property.

This patch ensures that scd->clock will not be set backward.

Subject: netlabel: Fix some sparse warnings

Fix a few sparse warnings.  One dealt with a RCU lock being held on error,
another dealt with an improper type caused by a signed/unsigned mixup while
the rest appeared to be caused by using rcu_dereference() in a
list_for_each_entry_rcu() call.  The latter probably isn't a big deal, but
I derive a certain pleasure from knowing that the net/netlabel is nice and
clean.

Thanks to James Morris for pointing out the issues and demonstrating how
to run sparse.

Subject: selinux: Cleanup the NetLabel glue code

We were doing a lot of extra work in selinux_netlbl_sock_graft() what wasn't
necessary so this patch removes that code.  It also removes the redundant
second argument to selinux_netlbl_sock_setsid() which allows us to simplify a
few other functions.

Subject: selinux: Correctly handle IPv4 packets on IPv6 sockets in all cases

We did the right thing in a few cases but there were several areas where we
determined a packet's address family based on the socket's address family which
is not the right thing to do since we can get IPv4 packets on IPv6 sockets.
This patch fixes these problems by either taking the address family directly
from the packet.

Subject: netlabel: Remove unneeded in-kernel API functions

After some discussions with the Smack folks, well just Casey, I now have a
better idea of what Smack wants out of NetLabel in the future so I think it
is now safe to do some API "pruning".  If another LSM comes along that
needs this functionality we can always add it back in, but I don't see any
LSMs on the horizon which might make use of these functions.

Thanks to Rami Rosen who suggested removing netlbl_cfg_cipsov4_del() back
in February 2008.

Subject: selinux: Better local/forward check in selinux_ip_postroute()

It turns out that checking to see if skb->sk is NULL is not a very good
indicator of a forwarded packet as some locally generated packets also have
skb->sk set to NULL.  Fix this by not only checking the skb->sk field but also
the IP[6]CB(skb)->flags field for the IP[6]SKB_FORWARDED flag.  While we are
at it, we are calling selinux_parse_skb() much earlier than we really should
resulting in potentially wasted cycles parsing packets for information we
might no use; so shuffle the code around a bit to fix this.

Subject: selinux: Fix a problem in security_netlbl_sid_to_secattr()

Currently when SELinux fails to allocate memory in
security_netlbl_sid_to_secattr() the NetLabel LSM domain field is set to
NULL which triggers the default NetLabel LSM domain mapping which may not
always be the desired mapping.  This patch fixes this by returning an error
when the kernel is unable to allocate memory.  This could result in more
failures on a system with heavy memory pressure but it is the "correct"
thing to do.

Subject: selinux: Fix missing calls to netlbl_skbuff_err()

At some point I think I messed up and dropped the calls to netlbl_skbuff_err()
which are necessary for CIPSO to send error notifications to remote systems.
This patch re-introduces the error handling calls into the SELinux code.

Subject: netlabel: Replace protocol/NetLabel linking with refrerence counts

NetLabel has always had a list of backpointers in the CIPSO DOI definition
structure which pointed to the NetLabel LSM domain mapping structures which
referenced the CIPSO DOI struct.  The rationale for this was that when an
administrator removed a CIPSO DOI from the system all of the associated
NetLabel LSM domain mappings should be removed as well; a list of
backpointers made this a simple operation.

Unfortunately, while the backpointers did make the removal easier they were
a bit of a mess from an implementation point of view which was making
further development difficult.  Since the removal of a CIPSO DOI is a
realtively rare event it seems to make sense to remove this backpointer
list as the optimization was hurting us more then it was helping.  However,
we still need to be able to track when a CIPSO DOI definition is being used
so replace the backpointer list with a reference count.  In order to
preserve the current functionality of removing the associated LSM domain
mappings when a CIPSO DOI is removed we walk the LSM domain mapping table,
removing the relevant entries.

Subject: netlabel: Add a generic way to create ordered linked lists of network
 addrs

Create an ordered IP address linked list mechanism similar to the core
kernel's linked list construct.  The idea behind this list functionality
is to create an extensibile linked list ordered by IP address mask to
ease the matching of network addresses.  The linked list is ordered with
larger address masks at the front of the list and shorter address masks
at the end to facilitate overriding network entries with individual host
or subnet entries.

Subject: netlabel: Add network address selectors to the NetLabel/LSM domain
 mapping

This patch extends the NetLabel traffic labeling capabilities to individual
packets based not only on the LSM domain but the by the destination address
as well.  The changes here only affect the core NetLabel infrastructre,
changes to the NetLabel KAPI and individial protocol engines are also
required but are split out into a different patch to ease review.

From 948bf85c1bc9a84754786a9d5dd99b7ecc46451e Mon Sep 17 00:00:00 2001
From: Paul Moore <paul.moore@hp.com>
Date: Fri, 10 Oct 2008 10:16:32 -0400
Subject: netlabel: Add functionality to set the security attributes of a
 packet

This patch builds upon the new NetLabel address selector functionality by
providing the NetLabel KAPI and CIPSO engine support needed to enable the
new packet-based labeling.  The only new addition to the NetLabel KAPI at
this point is shown below:

 * int netlbl_skbuff_setattr(skb, family, secattr)

... and is designed to be called from a Netfilter hook after the packet's
IP header has been populated such as in the FORWARD or LOCAL_OUT hooks.

This patch also provides the necessary SELinux hooks to support this new
functionality.  Smack support is not currently included due to uncertainty
regarding the permissions needed to expand the Smack network access controls.

From 014ab19a69c325f52d7bae54ceeda73d6307ae0c Mon Sep 17 00:00:00 2001
From: Paul Moore <paul.moore@hp.com>
Date: Fri, 10 Oct 2008 10:16:33 -0400
Subject: selinux: Set socket NetLabel based on connection endpoint

Previous work enabled the use of address based NetLabel selectors, which while
highly useful, brought the potential for additional per-packet overhead when
used.  This patch attempts to solve that by applying NetLabel socket labels
when sockets are connect()'d.  This should alleviate the per-packet NetLabel
labeling for all connected sockets (yes, it even works for connected DGRAM
sockets).

Subject: selinux: Cache NetLabel secattrs in the socket's security struct

Previous work enabled the use of address based NetLabel selectors, which
while highly useful, brought the potential for additional per-packet overhead
when used.  This patch attempts to mitigate some of that overhead by caching
the NetLabel security attribute struct within the SELinux socket security
structure.  This should help eliminate the need to recreate the NetLabel
secattr structure for each packet resulting in less overhead.

Subject: netlabel: Changes to the NetLabel security attributes to allow LSMs
 to pass full contexts

This patch provides support for including the LSM's secid in addition to
the LSM's MLS information in the NetLabel security attributes structure.

Subject: cipso: Add support for native local labeling and fixup mapping names

This patch accomplishes three minor tasks: add a new tag type for local
labeling, rename the CIPSO_V4_MAP_STD define to CIPSO_V4_MAP_TRANS and
replace some of the CIPSO "magic numbers" with constants from the header
file.  The first change allows CIPSO to support full LSM labels/contexts,
not just MLS attributes.  The second change brings the mapping names inline
with what userspace is using, compatibility is preserved since we don't
actually change the value.  The last change is to aid readability and help
prevent mistakes.

Subject: NFS: fix nfs_parse_ip_address() corner case

Bruce observed that nfs_parse_ip_address() will successfully parse an
IPv6 address that looks like this:

  "::1%"

A scope delimiter is present, but there is no scope ID following it.
This is harmless, as it would simply set the scope ID to zero.  However,
in some cases we would like to flag this as an improperly formed
address.

We are now also careful to reject addresses where garbage follows the
address (up to the length of the string), instead of ignoring the
non-address characters; and where the scope ID is nonsense (not a valid
device name, but also not numeric).  Before, both of these cases would
result in a harmless zero scope ID.

Subject: RPC/RDMA: check selected memory registration mode at runtime.

At transport creation, check for, and use, any local dma lkey.
Then, check that the selected memory registration mode is in fact
supported by the RDMA adapter selected for the mount. Fall back
to best alternative if not.

Subject: RPC/RDMA: support FRMR client memory registration.

Configure, detect and use "fastreg" support from IB/iWARP verbs
layer to perform RPC/RDMA memory registration.

Make FRMR the default memreg mode (will fall back if not supported
by the selected RDMA adapter).

This allows full and optimal operation over the cxgb3 adapter, and others.

From b334eaabf4f92226d2df13c613888a507f03da99 Mon Sep 17 00:00:00 2001
From: Tom Tucker <tom@opengridcomputing.com>

Subject: RPC/RDMA: fix connection IRD/ORD setting

This logic sets the connection parameter that configures the local device
and informs the remote peer how many concurrent incoming RDMA_READ
requests are supported. The original logic didn't really do what was
intended for two reasons:

- The max number supported by the device is typically smaller than
any one factor in the calculation used, and

- The field in the connection parameter structure where the value is
stored is a u8 and always overflows for the default settings.

So what really happens is the value requested for responder resources
is the left over 8 bits from the "desired value". If the desired value
happened to be a multiple of 256, the result was zero and it wouldn't
connect at all.

Given the above and the fact that max_requests is almost always larger
than the max responder resources supported by the adapter, this patch
simplifies this logic and simply requests the max supported by the device,
subject to a reasonable limit.

This bug was found by Jim Schutt at Sandia.

Subject: RPC/RDMA: suppress retransmit on RPC/RDMA clients.

An RPC/RDMA client cannot retransmit on an unbroken connection,
doing so violates its flow control with the server.

Subject: RPC/RDMA: avoid an oops due to disconnect racing with async upcalls.

RDMA disconnects yield an upcall from the RDMA connection manager,
which can race with rpc transport close, e.g. on ^C of a mount.
Ensure any rdma cm_id and qp are fully destroyed before continuing.

Subject: RPC/RDMA: adhere to protocol for unpadded client trailing write
 chunks.

The RPC/RDMA protocol allows clients and servers to avoid RDMA
operations for data which is purely the result of XDR padding.
On the client, automatically insert the necessary padding for
such server replies, and optionally don't marshal such chunks.

Subject: RPC/RDMA: return a consistent error, when connect fails.

The xprt_connect call path does not expect such errors as ECONNREFUSED
to be returned from failed transport connection attempts, otherwise it
translates them to EIO and signals fatal errors. For example, mount.nfs
prints simply "internal error". Translate all such errors to ENOTCONN
from RPC/RDMA to match sockets behavior.

Subject: RPC/RDMA: reformat a debug printk to keep lines together.

The send marshaling code split a particular dprintk across two
lines, which makes it hard to extract from logfiles.

Subject: RPC/RDMA: correct the reconnect timer backoff

The RPC/RDMA code had a constant 5-second reconnect backoff, and
always performed it, even when re-establishing a connection to a
server after the RPC layer closed it due to being idle. Make it
an geometric backoff (up to 30 seconds), and don't delay idle
reconnect.

Subject: The tpm_dev_release function is only called for platform devices, not
 pnp devices, so we implemented the .remove function for pnp ones.  Since it's
 code is very similar to the one inside tpm_dev_release, we've created a
 helper function tpm_dev_vendor_release, which is called by both.

Subject: Staging: add TAINT_CRAP for all drivers/staging code

We need to add a flag for all code that is in the drivers/staging/
directory to prevent all other kernel developers from worrying about
issues here, and to notify users that the drivers might not be as good
as they are normally used to.

Based on code from Andreas Gruenbacher and Jeff Mahoney to provide a
TAINT flag for the support level of a kernel module in the Novell
enterprise kernel release.

This is the kernel portion of this feature, the ability for the flag to
be set needs to be done in the build process and will happen in a
follow-up patch.

Subject: Staging: add et131x network driver

This is a driver for the ET1310 network device.

Based on the driver found at https://sourceforge.net/projects/et131x/

Cleaned up immensely by Olaf Hartman <o.hartmann@telovital.com> and Christoph
Hellwig <hch@infradead.org>

Note, the powermanagement options were removed from the vendor provided
driver as they did not build properly at the time.

TODO:
	- kernel coding style cleanups
	- forward port for latest network driver changes
	- kill useless typecasts (e.g. in et1310_phy.c)
	- alloc_etherdev is initializing memory with zero?!?
	- add_timer call in et131x_netdev.c is correct?
	- Add power saving functionality (suspend, sleep, resume)
	- Implement a few more kernel Parameter (set mac )

+This is a driver for the ET1310 network device.
+
+Based on the driver found at https://sourceforge.net/projects/et131x/
+
+Cleaned up immensely by Olaf Hartman <o.hartmann@telovital.com> and Christoph
+Hellwig <hch@infradead.org>
+
+Note, the powermanagement options were removed from the vendor provided
+driver as they did not build properly at the time.
+
+TODO:
+	- kernel coding style cleanups
+	- forward port for latest network driver changes
+	- kill useless typecasts (e.g. in et1310_phy.c)
+	- alloc_etherdev is initializing memory with zero?!?
+	- add_timer call in et131x_netdev.c is correct?
+	- Add power saving functionality (suspend, sleep, resume)
+	- Implement a few more kernel Parameter (set mac )
+
+Please send patches to:
+	Greg Kroah-Hartman <gregkh@suse.de>
+
+And Cc: Olaf Hartmann <o.hartmann@telovital.com> as he has this device and can
+test any changes.

+	 *
+	 * Single Byte Writes
+	 *
+	 * For an EEPROM, an I2C single byte write is defined as a START
+	 * condition followed by the device address, EEPROM address, one byte
+	 * of data and a STOP condition.  The STOP condition will trigger the
+	 * EEPROM's internally timed write cycle to the nonvolatile memory.
+	 * All inputs are disabled during this write cycle and the EEPROM will
+	 * not respond to any access until the internal write is complete.
+	 * The steps to execute a single byte write are as follows:
+	 *
+	 * 1. Check LBCIF Status Register for bits 6 & 3:2 all equal to 0 and
+	 *    bits 7,1:0 both equal to 1, at least once after reset.
+	 *    Subsequent operations need only to check that bits 1:0 are
+	 *    equal to 1 prior to starting a single byte write.
+	 *
+	 * 2. Write to the LBCIF Control Register:  bit 7=1, bit 6=1, bit 3=0,
+	 *    and bits 1:0 both =0.  Bit 5 should be set according to the
+	 *    type of EEPROM being accessed (1=two byte addressing, 0=one
+	 *    byte addressing).
+	 *
+	 * 3. Write the address to the LBCIF Address Register.
+	 *
+	 * 4. Write the data to the LBCIF Data Register (the I2C write will
+	 *    begin).
+	 *
+	 * 5. Monitor bit 1:0 of the LBCIF Status Register.  When bits 1:0 are
+	 *    both equal to 1, the I2C write has completed and the internal
+	 *    write cycle of the EEPROM is about to start. (bits 1:0 = 01 is
+	 *    a legal state while waiting from both equal to 1, but bits
+	 *    1:0 = 10 is invalid and implies that something is broken).
+	 *
+	 * 6. Check bit 3 of the LBCIF Status Register.  If  equal to 1, an
+	 *    error has occurred.
+	 *
+	 * 7. Check bit 2 of the LBCIF Status Register.  If equal to 1 an ACK
+	 *    error has occurred on the address phase of the write.  This
+	 *    could be due to an actual hardware failure or the EEPROM may
+	 *    still be in its internal write cycle from a previous write.
+	 *    This write operation was ignored and must be repeated later.
+	 *
+	 * 8. Set bit 6 of the LBCIF Control Register = 0. If another write is
+	 *    required, go to step 1.

From 4d6f6af8d6e76443f298ac030b0fc4fe84bdbd6a Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Wed, 19 Mar 2008 14:27:25 -0700
Subject: Staging: add Alacritech slicoss network driver

This adds the Alacritech slicoss driver to the tree.

This driver is supposed to support:

	Mojave cards (single port PCI Gigabit) both copper and fiber
	Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
	Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber

The driver was acutally tested on Oasis and Kalahari cards.

TODO:
	- move firmware loading to request_firmware()
	- remove direct memory access of structures
	- any remaining sparse and checkpatch.pl warnings
	- any netdev recommended changes

Many thanks to Lior Dotan <liodot@gmail.com> for help with the cleanup
of this driver.

Subject: Staging: add sxg network driver

This is the first rough cut at a driver for the Alacritech SLIC
Technology Non-Accelerated 10Gbe network driver

TODO:
  - lindent the code
  - remove typedefs
  - remove wrappers
  - checkpatch.pl cleanups
  - new functionality that the card needs

+ * Receive data buffers
+ *
+ * Receive data buffers are given to the Sahara card 128 at a time.
+ * This is accomplished by filling in a "receive descriptor block"
+ * with 128 "receive descriptors".  Each descriptor consists of
+ * a physical address, which the card uses as the address to
+ * DMA data into, and a virtual address, which is given back
+ * to the host in the "HostHandle" portion of an event.
+ * The receive descriptor data structure is defined below
+ * as SXG_RCV_DATA_DESCRIPTOR, and the corresponding block
+ * is defined as SXG_RCV_DESCRIPTOR_BLOCK.
+ *
+ * This receive descriptor block is given to the card by filling
+ * in the Sgl field of a SXG_CMD entry from pAdapt->RcvRings[0]
+ * with the physical address of the receive descriptor block.
+ *
+ * Both the receive buffers and the receive descriptor blocks
+ * require additional data structures to maintain them
+ * on a free queue and contain other information associated with them.
+ * Those data structures are defined as the SXG_RCV_DATA_BUFFER_HDR
+ * and SXG_RCV_DESCRIPTOR_BLOCK_HDR respectively.
+ *
+ * Since both the receive buffers and the receive descriptor block
+ * must be accessible by the card, both must be allocated out of
+ * shared memory.  To ensure that we always have a descriptor
+ * block available for every 128 buffers, we allocate all of
+ * these resources together in a single block.  This entire
+ * block is managed by a SXG_RCV_BLOCK_HDR, who's sole purpose
+ * is to maintain address information so that the entire block
+ * can be free later.
+ *
+ * Further complicating matters is the fact that the receive
+ * buffers must be variable in length in order to accomodate
+ * jumbo frame configurations.  We configure the buffer
+ * length so that the buffer and it's corresponding SXG_RCV_DATA_BUFFER_HDR
+ * structure add up to an even boundary.  Then we place the
+ * remaining data structures after 128 of them as shown in
+ * the following diagram:

+// The following definition specifies the amount of shared memory to allocate
+// for the SCATTER_GATHER_LIST portion of the SXG_SCATTER_GATHER data structure.
+// The following considerations apply when setting this value:
+// - First, the Sahara card is designed to read the Microsoft SGL structure
+// 	 straight out of host memory.  This means that the SGL must reside in
+//	 shared memory.  If the length here is smaller than the SGL for the
+//	 NET_BUFFER, then NDIS will allocate its own buffer.  The buffer
+//	 that NDIS allocates is not in shared memory, so when this happens,
+//	 the SGL will need to be copied to a set of SXG_SCATTER_GATHER buffers.
+//	 In other words.. we don't want this value to be too small.
+// - On the other hand.. we're allocating up to 16k of these things.  If
+//	 we make this too big, we start to consume a ton of memory..
+// At the moment, I'm going to limit the number of SG entries to 150.
+// If each entry maps roughly 4k, then this should cover roughly 600kB
+// NET_BUFFERs.  Furthermore, since each entry is 24 bytes, the total
+// SGE portion of the structure consumes 3600 bytes, which should allow
+// the entire SXG_SCATTER_GATHER structure to reside comfortably within
+// a 4k block, providing the remaining fields stay under 500 bytes.
+//
+// So with 150 entries, the SXG_SCATTER_GATHER structure becomes roughly

+// manageable.

From 866b8695d67e83f47194731d3a7ba55826a7ec70 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Fri, 15 Feb 2008 16:53:09 -0800
Subject: Staging: add the go7007 video driver

Todo:
	- checkpatch.pl cleanups
	- sparse cleanups
	- lots of little modules, should be merged together
	  and added to the build.
	- testing?
	- handle churn in v4l layer.

Many thanks to Ross Cohen <rcohen@snurgle.org> for cleanup patches on
this driver.

+ *
+ * When a new go7007 device is connected, we can look up in a board info

+ * itself here, and then we can call the registered detect_client function
+ * to force-load a new client at the address listed in the board info table.
+ *
+ * Really the I2C subsystem should have a way to force-load I2C client
+ * drivers when we have a priori knowledge of what's on the bus, especially
+ * since the existing I2C auto-probe mechanism is so hokey, but we'll use
+ * our own mechanism for the time being. */

Subject: Staging: USB/IP: add common functions needed

This adds the common functions needed by both the host and client side
of the USB/IP code.

Brian Merrell cleaned up a lot of this code and submitted it for
inclusion.  Greg also did a lot of cleanup.

Subject: Staging: add w35und wifi driver

This is driver for w35und usb wifi -- also in kohjinsha
subnotebook. It should work well enough to associate and ping, but it
obviously needs to be rewritten two more times...

OTOH worst horrors (like embedded wifi stack) should have been fixed
already...

Subject: Staging: add wlan-ng prism2 usb driver

This adds the wlan-ng prism2 USB driver to the drivers/staging tree.

The code was originally written by the linux-wlan-ng team, patched by
some Novell engineers to properly work on newer kernels, and then hacked
into place in order to get it to build properly in a single subdirectory
within the kernel tree by me.

It supports a wide range of older USB prism2 devices, and contains a
80211 stack to support this single driver.

+*
+* --------------------------------------------------------------------
+*
+* This file implements functions that correspond to the prism2/hfa384x
+* 802.11 MAC hardware and firmware host interface.
+*
+* The functions can be considered to represent several levels of
+* abstraction.  The lowest level functions are simply C-callable wrappers
+* around the register accesses.  The next higher level represents C-callable
+* prism2 API functions that match the Intersil documentation as closely
+* as is reasonable.  The next higher layer implements common sequences
+* of invokations of the API layer (e.g. write to bap, followed by cmd).
+*
+* Common sequences:
+* hfa384x_drvr_xxx	Highest level abstractions provided by the
+*			hfa384x code.  They are driver defined wrappers
+*			for common sequences.  These functions generally
+*			use the services of the lower levels.
+*
+* hfa384x_drvr_xxxconfig  An example of the drvr level abstraction. These
+*			functions are wrappers for the RID get/set
+*			sequence. They 	call copy_[to|from]_bap() and
+*			cmd_access().	These functions operate on the
+*			RIDs and buffers without validation.  The caller
+*			is responsible for that.
+*
+* API wrapper functions:
+* hfa384x_cmd_xxx	functions that provide access to the f/w commands.
+*			The function arguments correspond to each command
+*			argument, even command arguments that get packed
+*			into single registers.  These functions _just_
+*			issue the command by setting the cmd/parm regs
+*			& reading the status/resp regs.  Additional
+*			activities required to fully use a command
+*			(read/write from/to bap, get/set int status etc.)
+*			are implemented separately.  Think of these as
+*			C-callable prism2 commands.
+*
+* Lowest Layer Functions:
+* hfa384x_docmd_xxx	These functions implement the sequence required
+*			to issue any prism2 command.  Primarily used by the
+*			hfa384x_cmd_xxx functions.
+*
+* hfa384x_bap_xxx	BAP read/write access functions.
+*			Note: we usually use BAP0 for non-interrupt context
+*			 and BAP1 for interrupt context.
+*
+* hfa384x_dl_xxx	download related functions.
+*
+* Driver State Issues:
+* Note that there are two pairs of functions that manage the
+* 'initialized' and 'running' states of the hw/MAC combo.  The four
+* functions are create(), destroy(), start(), and stop().  create()
+* sets up the data structures required to support the hfa384x_*
+* functions and destroy() cleans them up.  The start() function gets
+* the actual hardware running and enables the interrupts.  The stop()
+* function shuts the hardware down.  The sequence should be:
+* create()
+*  .
+*  .  Self contained test routines can run here, particularly
+*  .  corereset() and test_hostif().
+*  .
+* start()
+*  .
+*  .  Do interesting things w/ the hardware
+*  .
+* stop()
+* destroy()
+*
+* Note that destroy() can be called without calling stop() first.

+ * a paged address space where the upper 16 bits are the page number
+ * and the lower 7 bits are the offset.  There are various Host API
+ * elements that require two 16-bit quantities to specify a MAC
+ * internal memory address.  Unfortunately, some of the API's use a
+ * page/offset format where the offset value is JUST the lower seven
+ * bits and the page is  the remaining 16 bits.  Some of the API's
+ * assume that the 23 bit address has been split at the 16th bit.  We
+ * refer to these two formats as AUX format and CMD format.  The
+ * macros below help handle some of this.

+* --------------------------------------------------------------------
+*
+* This file implements functions that correspond to the prism2/hfa384x
+* 802.11 MAC hardware and firmware host interface.
+*
+* The functions can be considered to represent several levels of
+* abstraction.  The lowest level functions are simply C-callable wrappers
+* around the register accesses.  The next higher level represents C-callable
+* prism2 API functions that match the Intersil documentation as closely
+* as is reasonable.  The next higher layer implements common sequences
+* of invokations of the API layer (e.g. write to bap, followed by cmd).
+*
+* Common sequences:
+* hfa384x_drvr_xxx	Highest level abstractions provided by the
+*			hfa384x code.  They are driver defined wrappers
+*			for common sequences.  These functions generally
+*			use the services of the lower levels.
+*
+* hfa384x_drvr_xxxconfig  An example of the drvr level abstraction. These
+*			functions are wrappers for the RID get/set
+*			sequence. They 	call copy_[to|from]_bap() and
+*			cmd_access().	These functions operate on the
+*			RIDs and buffers without validation.  The caller
+*			is responsible for that.
+*
+* API wrapper functions:
+* hfa384x_cmd_xxx	functions that provide access to the f/w commands.
+*			The function arguments correspond to each command
+*			argument, even command arguments that get packed
+*			into single registers.  These functions _just_
+*			issue the command by setting the cmd/parm regs
+*			& reading the status/resp regs.  Additional
+*			activities required to fully use a command
+*			(read/write from/to bap, get/set int status etc.)
+*			are implemented separately.  Think of these as
+*			C-callable prism2 commands.
+*
+* Lowest Layer Functions:
+* hfa384x_docmd_xxx	These functions implement the sequence required
+*			to issue any prism2 command.  Primarily used by the
+*			hfa384x_cmd_xxx functions.
+*
+* hfa384x_bap_xxx	BAP read/write access functions.
+*			Note: we usually use BAP0 for non-interrupt context
+*			 and BAP1 for interrupt context.
+*
+* hfa384x_dl_xxx	download related functions.
+*
+* Driver State Issues:
+* Note that there are two pairs of functions that manage the
+* 'initialized' and 'running' states of the hw/MAC combo.  The four
+* functions are create(), destroy(), start(), and stop().  create()
+* sets up the data structures required to support the hfa384x_*
+* functions and destroy() cleans them up.  The start() function gets
+* the actual hardware running and enables the interrupts.  The stop()
+* function shuts the hardware down.  The sequence should be:
+* create()
+* start()
+*  .
+*  .  Do interesting things w/ the hardware
+*  .
+* stop()
+* destroy()
+*
+* Note that destroy() can be called without calling stop() first.

+*  the p80211 request/confirm/indicate interfaces on Linux.  The
+*  request/confirm interface is, in fact, normally implemented as an
+*  ioctl.  The indicate interface on the other hand, is implemented
+*  using the Linux 'netlink' interface.
+*
+*  The reason I say that request/confirm is 'normally' implemented
+*  via ioctl is that we're reserving the right to be able to send
+*  request commands via the netlink interface.  This will be necessary
+*  if we ever need to send request messages when there aren't any
+*  wlan network devices present (i.e. sending a message that only p80211
+*  cares about.

+*
+* This file declares the constants and types used in the interface
+* between a wlan driver and the user mode utilities.
+*
+* Notes:
+*  - Constant values are always in HOST byte order.  To assign
+*    values to multi-byte fields they _must_ be converted to
+*    ieee byte order.  To retrieve multi-byte values from incoming
+*    frames, they must be converted to host order.
+*
+*  - The len member of the frame structure does NOT!!! include
+*    the MAC CRC.  Therefore, the len field on rx'd frames should
+*    have 4 subtracted from it.
+*
+* All functions declared here are implemented in p80211.c
+*
+* The types, macros, and functions defined here are primarily
+* used for encoding and decoding management frames.  They are
+* designed to follow these patterns of use:
+*
+* DECODE:
+* 1) a frame of length len is received into buffer b
+* 2) using the hdr structure and macros, we determine the type
+* 3) an appropriate mgmt frame structure, mf, is allocated and zeroed
+* 4) mf.hdr = b
+*    mf.buf = b
+*    mf.len = len
+* 5) call mgmt_decode( mf )
+* 6) the frame field pointers in mf are now set.  Note that any
+*    multi-byte frame field values accessed using the frame field
+*    pointers are in ieee byte order and will have to be converted
+*    to host order.
+*
+* ENCODE:
+* 1) Library client allocates buffer space for maximum length
+*    frame of the desired type
+* 2) Library client allocates a mgmt frame structure, called mf,
+*    of the desired type
+* 3) Set the following:
+*    mf.type = <desired type>
+*    mf.buf = <allocated buffer address>
+* 4) call mgmt_encode( mf )
+* 5) all of the fixed field pointers and fixed length information element
+*    pointers in mf are now set to their respective locations in the
+*    allocated space (fortunately, all variable length information elements
+*    fall at the end of their respective frames).
+* 5a) The length field is set to include the last of the fixed and fixed
+*     length fields.  It may have to be updated for optional or variable
+* 	length information elements.
+* 6) Optional and variable length information elements are special cases
+*    and must be handled individually by the client code.

+* cases but has different behavior.

+/* Implementation Notes
+   David Rowe
+   April 2007
+
+   This code started life as Steve's NLMS algorithm with a tap
+   rotation algorithm to handle divergence during double talk.  I
+   added a Geigel Double Talk Detector (DTD) [2] and performed some
+   G168 tests.  However I had trouble meeting the G168 requirements,
+   especially for double talk - there were always cases where my DTD
+   failed, for example where near end speech was under the 6dB
+   threshold required for declaring double talk.
+
+   So I tried a two path algorithm [1], which has so far given better
+   results.  The original tap rotation/Geigel algorithm is available
+   in SVN http://svn.rowetel.com/software/oslec/tags/before_16bit.
+   It's probably possible to make it work if some one wants to put some
+   serious work into it.
+
+   At present no special treatment is provided for tones, which
+   generally cause NLMS algorithms to diverge.  Initial runs of a
+   subset of the G168 tests for tones (e.g ./echo_test 6) show the
+   current algorithm is passing OK, which is kind of surprising.  The
+   full set of tests needs to be performed to confirm this result.
+
+   One other interesting change is that I have managed to get the NLMS
+   code to work with 16 bit coefficients, rather than the original 32
+   bit coefficents.  This reduces the MIPs and storage required.
+   I evaulated the 16 bit port using g168_tests.sh and listening tests
+   on 4 real-world samples.
+
+   I also attempted the implementation of a block based NLMS update
+   [2] but although this passes g168_tests.sh it didn't converge well
+   on the real-world samples.  I have no idea why, perhaps a scaling
+   problem.  The block based code is also available in SVN
+   http://svn.rowetel.com/software/oslec/tags/before_16bit.  If this
+   code can be debugged, it will lead to further reduction in MIPS, as
+   the block update code maps nicely onto DSP instruction sets (it's a
+   dot product) compared to the current sample-by-sample update.
+
+   Steve also has some nice notes on echo cancellers in echo.h

+/*! \page echo_can_page Line echo cancellation for voice
+
+\section echo_can_page_sec_1 What does it do?
+This module aims to provide G.168-2002 compliant echo cancellation, to remove
+electrical echoes (e.g. from 2-4 wire hybrids) from voice calls.
+
+\section echo_can_page_sec_2 How does it work?
+The heart of the echo cancellor is FIR filter. This is adapted to match the
+echo impulse response of the telephone line. It must be long enough to
+adequately cover the duration of that impulse response. The signal transmitted
+to the telephone line is passed through the FIR filter. Once the FIR is
+properly adapted, the resulting output is an estimate of the echo signal
+received from the line. This is subtracted from the received signal. The result
+is an estimate of the signal which originated at the far end of the line, free
+from echos of our own transmitted signal.
+
+The least mean squares (LMS) algorithm is attributed to Widrow and Hoff, and
+was introduced in 1960. It is the commonest form of filter adaption used in
+things like modem line equalisers and line echo cancellers. There it works very
+well.  However, it only works well for signals of constant amplitude. It works
+very poorly for things like speech echo cancellation, where the signal level
+varies widely.  This is quite easy to fix. If the signal level is normalised -
+similar to applying AGC - LMS can work as well for a signal of varying
+amplitude as it does for a modem signal. This normalised least mean squares
+(NLMS) algorithm is the commonest one used for speech echo cancellation. Many
+other algorithms exist - e.g. RLS (essentially the same as Kalman filtering),
+FAP, etc. Some perform significantly better than NLMS.  However, factors such
+as computational complexity and patents favour the use of NLMS.
+
+A simple refinement to NLMS can improve its performance with speech. NLMS tends
+to adapt best to the strongest parts of a signal. If the signal is white noise,
+the NLMS algorithm works very well. However, speech has more low frequency than
+high frequency content. Pre-whitening (i.e. filtering the signal to flatten its
+spectrum) the echo signal improves the adapt rate for speech, and ensures the
+final residual signal is not heavily biased towards high frequencies. A very
+low complexity filter is adequate for this, so pre-whitening adds little to the
+compute requirements of the echo canceller.
+
+An FIR filter adapted using pre-whitened NLMS performs well, provided certain
+conditions are met:
+
+    - The transmitted signal has poor self-correlation.
+    - There is no signal being generated within the environment being
+      cancelled.
+
+The difficulty is that neither of these can be guaranteed.
+
+If the adaption is performed while transmitting noise (or something fairly
+noise like, such as voice) the adaption works very well. If the adaption is
+performed while transmitting something highly correlative (typically narrow
+band energy such as signalling tones or DTMF), the adaption can go seriously
+wrong. The reason is there is only one solution for the adaption on a near
+random signal - the impulse response of the line. For a repetitive signal,
+there are any number of solutions which converge the adaption, and nothing
+guides the adaption to choose the generalised one. Allowing an untrained
+canceller to converge on this kind of narrowband energy probably a good thing,
+since at least it cancels the tones. Allowing a well converged canceller to
+continue converging on such energy is just a way to ruin its generalised
+adaption. A narrowband detector is needed, so adapation can be suspended at
+appropriate times.
+
+The adaption process is based on trying to eliminate the received signal. When
+there is any signal from within the environment being cancelled it may upset
+the adaption process. Similarly, if the signal we are transmitting is small,
+noise may dominate and disturb the adaption process. If we can ensure that the
+adaption is only performed when we are transmitting a significant signal level,
+and the environment is not, things will be OK. Clearly, it is easy to tell when
+we are sending a significant signal. Telling, if the environment is generating
+a significant signal, and doing it with sufficient speed that the adaption will
+not have diverged too much more we stop it, is a little harder.
+
+The key problem in detecting when the environment is sourcing significant
+energy is that we must do this very quickly. Given a reasonably long sample of
+the received signal, there are a number of strategies which may be used to
+assess whether that signal contains a strong far end component. However, by the
+time that assessment is complete the far end signal will have already caused
+major mis-convergence in the adaption process. An assessment algorithm is
+needed which produces a fairly accurate result from a very short burst of far
+end energy.
+
+\section echo_can_page_sec_3 How do I use it?
+The echo cancellor processes both the transmit and receive streams sample by
+sample. The processing function is not declared inline. Unfortunately,
+cancellation requires many operations per sample, so the call overhead is only
+a minor burden.

+   Blackfin NOTES & IDEAS:
+
+   A simple dot product function is used to implement the filter.  This performs
+   just one MAC/cycle which is inefficient but was easy to implement as a first
+   pass.  The current Blackfin code also uses an unrolled form of the filter
+   history to avoid 0 length hardware loop issues.  This is wasteful of
+   memory.
+
+   Ideas for improvement:
+
+   1/ Rewrite filter for dual MAC inner loop.  The issue here is handling
+   history sample offsets that are 16 bit aligned - the dual MAC needs
+   32 bit aligmnent.  There are some good examples in libbfdsp.
+
+   2/ Use the hardware circular buffer facility tohalve memory usage.
+
+   3/ Consider using internal memory.
+
+   Using less memory might also improve speed as cache misses will be
+   reduced. A drop in MIPs and memory approaching 50% should be
+   possible.
+
+   The foreground and background filters currenlty use a total of
+   about 10 MIPs/ch as measured with speedtest.c on a 256 TAP echo
+   can.

Looks like there is one more instance where ext4dev should be changed
to ext4 because the module name will be "ext4" unless EXT4DEV_COMPAT

With this patch we track the block freed during a transaction using
red-black tree.  We also make sure contiguous blocks freed are collected
in one node in the tree.

Subject: V4L/DVB (8554): media/video/Kconfig: cosmetic changes and convert
 select into depends on

It seems cosmetically better to let USB drivers be the last one.

Also, two SOC drivers were using select, instead of depends on SOC_CAMERA.

Since select has some drawbacks when checking for dependencies, convert those
two into depends on.

Subject: V4L/DVB (8613): v4l: move BKL down to the driver level.

The BKL is now moved from the video_open function in v4l2-dev.c to the
various drivers. It seems about a third of the drivers already has a
lock of some sort protecting the open(), another third uses
video_exclusive_open (yuck!) and the last third required adding the
BKL in their open function.

Subject: V4L/DVB (8625): saa7134: Add NEC prococol IR decoding capability

This patch adds the capability of decoding NEC protocol, received via GPIO18 line.
This GPIO port can trigger saa7134 IRQ.

A future improvement would be to make it a little more generic to work also
with GPIO16 line.

A pure IRQ code didn't work, since some delays were introduced on the tests we
did.

A possible approach would be to use polling at a rate of 2.5 ms or less. If a
new code were taken, a code similar to nec_task() could be used. However, this
would add an extra overhead to kernel, and will consume more power.

Due to that, we took an hybrid approach: an IRQ upper half to trigger when a
new key is received and a bottom half to convert pulse-distance into a keycode.

The bottom half is polling based, to improve performance. During the bottom
half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and
improving performance a little bit.

Thanks to Sistema Fenix (http://www.sistemafenix.com.br/) for sponsoring this
development.

Add function that returns the control name. Allows this to be used in
places where the normal v4l2_ctrl_query_fill() function cannot be
used (e.g. uvc).

Subject: V4L/DVB (8637): v4l2: add v4l2_ctrl_query_menu_valid_items support
 function

v4l2_ctrl_query_menu_valid_items() makes it easy to handle control menus
that have a lot of invalid 'holes'. For example, many MPEG encoders only
support a limited subset of audio bitrates. In that case a driver can
specify an array listing the set of valid bitrates and pass that to
this function.

Subject: V4L/DVB (8642): cx23885: Factor out common cx23885 tuner callback

Tuners currently hook different things to the private pointer in their
callback function. Longer term we should make that private pointer
consistent, but for now separate out the guts of the cx23885 tuner callback
so we can reuse it.

Subject: V4L/DVB (8654): cxusb: add support for DViCO FusionHDTV DVB-T Dual
 Digital 4 (rev 2)

Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4
which has new tuners and demodulators (2 x DIB7070p). With this patch
both DVB reception and IR works.

The dib7000p driver currently hardwires the output mode to
OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow
OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the
check completely and set the output mode correctly in all the callers.

Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled.
It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but
this is what the other DIB7070 module does (there are a number of
module dependencies in the attach code).

From dfbdce04905d3196c828ca36f01ef06e6fdb2428 Mon Sep 17 00:00:00 2001

Subject: V4L/DVB (8657): cxusb: add lgs8gl5 and support for Magic-Pro DMB-TH
 usb stick

Add support for Magic-Pro DMB-TH usb stick.  DMB-TH is the HDTV broadcast
standard used in Hong Kong and China.
[...]
I've also attached a second patch against the dvb-apps repository which
adds a DMB-TH scan file for Hong Kong.

Since the ProHDTV stick contains a DMB-TH decoder (lgs8gl5) onboard,
it outputs MPEG-TS to the PC.

Adds support for Micron MT9M111 camera chip, with basic
features :
 - view rectangle configurable
 - some output formats (bayer8, bayer10, rgb565, rgb555, ycbycr)
 - autoexposure
 - only highpower mode context used (ie. context B)

Subject: V4L/DVB (8685): mt9m001, mt9v022: Simplify return code checking

i2c_smbus_write_word_data() returns 0 or a negative error, hence no need to
check for "> 0".

Subject: V4L/DVB (8689): dpc7146: remove dpc7146 demonstration board driver

Old driver for the dpc7146 demonstration board that is no longer
relevant. The last time this was tested on actual hardware was
probably around 2002. Since this is a driver for a demonstration
board the decision was made (after discussing this with the original
author, Michael Hunold) to remove it rather than spending a
lot of effort continually updating this driver to stay in sync
with the latest internal V4L2 or I2C API.

Subject: V4L/DVB (8690): tuner-3036: remove driver

This driver is for VERY old i2c-over-parallel port teletext receiver
boxes. Rather then spending effort on converting this driver to V4L2,
and since it is extremely unlikely that anyone still uses one of these
devices, it was decided to drop it (after discussing this as well with
the original author, Phil Blundell).

Subject: V4L/DVB (8724): dvb: drx397xD: checkpatch.pl cleanups

This driver sure needs some rework. For now, let's
try to clean it up a bit before start reimplementing
anything.

checkpatch.pl still not happy with this driver after
this patch, but the most annoying errors are gone,
comments now use C-style only, labels are well placed
and some other minor fixes.

Some more clean up patches will come as I work on this
driver. Please review it carefully.

Subject: V4L/DVB (8754): uvcvideo: Implement the USB power management
 reset_resume method.

When a suspended device has been reset instead of being resumed, USB core
calls the reset_resume method if available instead of unbinding and rebinding
the device.

This patch implements reset_resume by reusing the current resume
implementation and simplifies the resume method by skipping the controls
restore stage. Resuming from autosuspend should be faster.

Subject: V4L/DVB (8771): cx18: Remove redundant struct cx18_queue length
 member.

cx18: Remove redundant struct cx18_queue length member. It can be trivially
computed from queue->buffers * stream->buf_size, if ever really needed.

cx18: Fix cx18_find_handle() and add error checking.  cx18_find_handle() did
not find a good task handle and would use the invalid task handle under common
conditions.  Added a define for the invalid task handle and added error checking
as well.

Subject: V4L/DVB (8774): cx18: Have CX23418 release buffers at end of capture.

cx18: Have CX23418 release buffers at end of capture.  The CX23418 reuses task
handles so we need to have it release the buffers associated with a task handle
at the end of a capture.  If we don't, buffer ids used for one type of stream
in the driver (MPEG, TS, PCM), could be used for another type of stream by the
CX23418, if a previously used handle is assigned to a different type of stream.
The driver would drop valid buffers when this happened.

Subject: V4L/DVB (8782): v4l2-dev: add video_device_release_empty

Add a second release function: video_device_release_empty
It can be used by drivers that have statically allocated
video_device structs.

Its use usually, but not always, indicates laziness on the
part of the driver programmer.

Subject: V4L/DVB (8783): v4l: add all missing video_device release callbacks

All drivers that call video_device_register where checked to see if they
set the release callback of struct video_device. Where that callback was
missing it was added.

Subject: V4L/DVB (8784): v4l2-dev: make the video_device's release callback
 mandatory

Now that all drivers set the release callback in the video_device
struct we can put in a BUG_ON in video_register_device to ensure that
the callback is always there.

Subject: V4L/DVB (8786): v4l2: remove the priv field, use dev_get_drvdata

Remove the priv field and let video_get/set_drvdata use dev_get_drvdata
and dev_set_drvdata instead.

Convert all drivers that still used priv directly.

Subject: V4L/DVB (8791): v4l2-dev: do not clear the driver_data field

The driver_data field of the device structure was zeroed, thus losing
this information. Many drivers set this up before calling
video_device_register, so we have to ensure that it isn't lost.

Subject: V4L/DVB (8797): A simple state machine was added to saa7134_ts.

A simple state machine was added to saa7134_ts. It has three states:

        SAA7134_TS_STOPPED
        SAA7134_TS_BUFF_DONE
        SAA7134_TS_STARTED

When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED.
When all buffers are prepared we write data into DMA register and set
SAA7134_TS_BUFF_DONE.
When the first buffer is active start TS and set SAA7134_TS_STARTED.
When ts_release is called stop TS and set SAA7134_TS_STOPPED.

+			Soc-Camera Subsystem
+			====================
+
+Terminology
+-----------
+
+The following terms are used in this document:
+ - camera / camera device / camera sensor - a video-camera sensor chip, capable
+   of connecting to a variety of systems and interfaces, typically uses i2c for
+   control and configuration, and a parallel or a serial bus for data.
+ - camera host - an interface, to which a camera is connected. Typically a
+   specialised interface, present on many SoCs, e.g., PXA27x and PXA3xx, SuperH,
+   AVR32, i.MX27, i.MX31.
+ - camera host bus - a connection between a camera host and a camera. Can be
+   parallel or serial, consists of data and control lines, e.g., clock, vertical
+   and horizontal synchronization signals.
+
+Purpose of the soc-camera subsystem
+-----------------------------------
+
+The soc-camera subsystem provides a unified API between camera host drivers and
+camera sensor drivers. It implements a V4L2 interface to the user, currently
+only the mmap method is supported.
+
+This subsystem has been written to connect drivers for System-on-Chip (SoC)
+video capture interfaces with drivers for CMOS camera sensor chips to enable
+the reuse of sensor drivers with various hosts. The subsystem has been designed
+to support multiple camera host interfaces and multiple cameras per interface,
+although most applications have only one camera sensor.
+
+Existing drivers
+----------------
+
+As of 2.6.27-rc4 there are two host drivers in the mainline: pxa_camera.c for
+PXA27x SoCs and sh_mobile_ceu_camera.c for SuperH SoCs, and four sensor drivers:
+mt9m001.c, mt9m111.c, mt9v022.c and a generic soc_camera_platform.c driver. This
+list is not supposed to be updated, look for more examples in your tree.
+
+Camera host API
+---------------
+
+A host camera driver is registered using the
+
+soc_camera_host_register(struct soc_camera_host *);
+
+function. The host object can be initialized as follows:
+
+static struct soc_camera_host pxa_soc_camera_host = {
+	.drv_name	= PXA_CAM_DRV_NAME,
+	.ops		= &pxa_soc_camera_host_ops,
+};
+
+All camera host methods are passed in a struct soc_camera_host_ops:
+
+static struct soc_camera_host_ops pxa_soc_camera_host_ops = {
+	.owner		= THIS_MODULE,
+	.add		= pxa_camera_add_device,
+	.remove		= pxa_camera_remove_device,
+	.suspend	= pxa_camera_suspend,
+	.resume		= pxa_camera_resume,
+	.set_fmt_cap	= pxa_camera_set_fmt_cap,
+	.try_fmt_cap	= pxa_camera_try_fmt_cap,
+	.init_videobuf	= pxa_camera_init_videobuf,
+	.reqbufs	= pxa_camera_reqbufs,
+	.poll		= pxa_camera_poll,
+	.querycap	= pxa_camera_querycap,
+	.try_bus_param	= pxa_camera_try_bus_param,
+	.set_bus_param	= pxa_camera_set_bus_param,
+};
+
+.add and .remove methods are called when a sensor is attached to or detached
+from the host, apart from performing host-internal tasks they shall also call
+sensor driver's .init and .release methods respectively. .suspend and .resume
+methods implement host's power-management functionality and its their
+responsibility to call respective sensor's methods. .try_bus_param and
+.set_bus_param are used to negotiate physical connection parameters between the
+host and the sensor. .init_videobuf is called by soc-camera core when a
+video-device is opened, further video-buffer management is implemented completely
+by the specific camera host driver. The rest of the methods are called from
+respective V4L2 operations.
+
+Camera API
+----------
+
+Sensor drivers can use struct soc_camera_link, typically provided by the
+platform, and used to specify to which camera host bus the sensor is connected,
+and arbitrarily provide platform .power and .reset methods for the camera.
+soc_camera_device_register() and soc_camera_device_unregister() functions are
+used to add a sensor driver to or remove one from the system. The registration
+function takes a pointer to struct soc_camera_device as the only parameter.
+This struct can be initialized as follows:
+
+	/* link to driver operations */
+	icd->ops	= &mt9m001_ops;
+	/* link to the underlying physical (e.g., i2c) device */
+	icd->control	= &client->dev;
+	/* window geometry */
+	icd->x_min	= 20;
+	icd->y_min	= 12;
+	icd->x_current	= 20;
+	icd->y_current	= 12;
+	icd->width_min	= 48;
+	icd->width_max	= 1280;
+	icd->height_min	= 32;
+	icd->height_max	= 1024;
+	icd->y_skip_top	= 1;
+	/* camera bus ID, typically obtained from platform data */
+	icd->iface	= icl->bus_id;
+
+struct soc_camera_ops provides .probe and .remove methods, which are called by
+the soc-camera core, when a camera is matched against or removed from a camera
+host bus, .init, .release, .suspend, and .resume are called from the camera host
+driver as discussed above. Other members of this struct provide respective V4L2
+functionality.
+
+struct soc_camera_device also links to an array of struct soc_camera_data_format,
+listing pixel formats, supported by the camera.

Subject: V4L/DVB (8807): Add DVB support for the Leadtek Winfast PxDVR3200 H

This patch is on behalf of Stephen Backway <stev391@email.com>, and
represents two patches I received (and some subsequent whitespace
cleanup I had due to how I pulled the patches).

From the original author:

a) Add DVB support for the Leadtek Winfast PxDVR3200 H.

b) The tuner callback previously checked the command 3 times:
1) To see if it was the XC2028_RESET_CLK
2) To see if it was not the XC2028_RESET_TUNER
3) To see if it was the XC2028_RESET_TUNER
This patch removes the third check.

Subject: V4L/DVB (8838): CRED: Wrap task credential accesses in video input
 drivers

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

Subject: V4L/DVB (8852): v4l2: use register_chrdev_region instead of
 register_chrdev

Replace the old register_chrdev with the more flexible register_chrdev_region.

Ensure that the release() is called when the very last chardev usage was
released, and not when the sysfs devices were removed. This should simplify
hotpluggable drivers considerably.

Subject: V4L/DVB (8879): bttv: Don't unmask VPRES interrupt

When the input is set to tuner and no antenna is connected, the BT848
can flood VPRES interrupts. So we don't want to enable this type of
interrupts when the input it set to tuner.

As we don't do anything when receiving such an interrupt anyway, the
easiest fix is to simply not unmask this specific interrupt.

Subject: V4L/DVB (8889): dvb-ttpci: Support full-ts hardware modification

Add support for the 'full-ts' hardware modification.

On full-featured cards the data throughput is limited by the hardware
design. The full-ts mod removes this bottleneck, i.e. the card is able
to deliver the complete transport stream of a transponder.

For details see http://www.escape-edv.de/endriss/dvb-full-ts-mod

Subject: V4L/DVB (8894): pvrusb2: Remove BKL

The earlier change from Hans Verkuil that pushed the BKL from
video_open() down into the drivers should be unneeded for the pvrusb2
driver.  This driver's implementation for open already protects its
internal structures through other means, thus the BKL is not required.
This change reverses Hans' previous change, for the pvrusb2 driver.

It probably would have been a good idea for Hans to previously have
asked for my ack before committing his change.

Subject: V4L/DVB (8895): pvrusb2: Fail gracefully if an alien USB ID is used

The driver includes an internal table specifying additional
information on a per device-type basis.  This works great until
somebody tries to run-time associate another USB ID with the driver.
This change should hopefully allow the driver to fail gracefully under
such a circumstance.

Subject: V4L/DVB (8898): pvrusb2: Be able to programmatically retrieve a
 control's default value

The pvrusb2 control mechanism up until now has used a constant int to
hold a control's default value.  This change makes it possible to
retrieve the control's default through some other means, e.g. as a
result of a query from lower level software.

From 432907f750b27aa2b41e1bf398e6eb711ead448f Mon Sep 17 00:00:00 2001

Subject: V4L/DVB (8900): pvrusb2: Implement cropping pass through

This builds upon the previous pvrusb2 change to more formally
implement full cropping support.  This enables access from the
driver's V4L interface, and enables access to full capabilities from
sysfs as well.  Note that this is only effective when in analog mode.
It also will only work when the underlying digitizer's driver (saa7115
or cx25840 depending on the hardware) also implements the appropriate
functions.

Subject: V4L/DVB (8901): pvrusb2: Disable virtual IR device when not needed.

Disable "virtual" IR receiver on for 24xxx devices that have an
internal IR blaster.  In that case there's another another IR
receiver present and to leave the virtual receiver available
just causes confusion.  This means that 24xxx users will no
longer see a phantom IR chip.

From d45b9b8ab43c8973a9630ac54f4ede6c3e009f9e Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Thu, 4 Sep 2008 03:33:43 -0300
Subject: V4L/DVB (8906): v4l-dvb: fix assorted sparse warnings

Fix sparse warnings. None are serious, but cutting down on these helps find
future serious sparse warnings/errors.

Redid the av7710.c patch based on a suggestion by Oliver Endriss.

Subject: V4L/DVB (8912): cx18: Correct CX23418 PCI configuration settings.

cx18: Correct CX23418 PCI configuration settings.  The CX23418 doesn't have
I/O space registers, so there was no need to try and turn them on (the card
ignores the attempt to set the bit anyway).  Also removed incorrect config
space register setting that was errantly borrowed from ivtv.

From c641d09c60bfa36c7cf70444f24265090e51f5ce Mon Sep 17 00:00:00 2001
From: Andy Walls <awalls@radix.net>

Subject: V4L/DVB (8914): cx18: Throttle mmio to/from the CX23418 so boards
 work in older systems

cx18: Throttle mmio to/from the CX23418 so boards work in older systems.  The
CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was
attempting to access the chip.  The PCI bridge arrangements and settings on
modern motherboards still allowed the CX23418 to work OK, but it didn't work
well on many older motherboards: mysterious I2C errors, firmware loading errors,
etc.  This patch adds a throttle to *all* mmio access to the CX23418.  It
defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm.
My HVR-1600 and Raptor PAL/SECAM card now function for analog capture on a
motherboard with an Intel 82810E Northbridge and 82801AA Southbridge.

Subject: V4L/DVB (8915): cx18: Increment u8 pointers not void pointers.

cx18: Increment u8 pointers not void pointers.  Incrementing void pointers
is dubious and the real intent in cx18_memcpy_fromio() and cx18_memset_io() is
to increment by bytes, so use u8 pointers instead.

Subject: V4L/DVB (8917): saa7134-empress: fix changing the capture standard
 for non-tuner inputs

When changing the standard the saa6752hs was not updated unless the input
was the TV tuner. The saa6752hs should be updated regardless of the input.

In addition the S_STD and G_STD ioctls for the mpeg video device didn't do
anything. This is now fixed: they behave just like S_STD and G_STD on the
video0 device.

Subject: V4L/DVB (8921): ivtv: fix incorrect capability and assorted sliced
 vbi and video out fmt fixes

- V4L2_CAP_VBI_OUTPUT is not supported by ivtv, remove it.
- ivtv_try_fmt_vid_out also needed to constrain the width/height of MPEG decoder
  window sizes.
- allow empty sliced services.

Subject: V4L/DVB (8940): saa7115: fix saa7111(a) support

The saa7111 support in saa7115.c was missing some features and did not
properly take some of the differences into account. With this patch
saa7115 can be used in the mxb driver instead of saa7111.c.

From 707ecf4603a9439dcf409e13c5e9ed4e164ddfff Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sat, 6 Sep 2008 15:40:25 -0300
Subject: V4L/DVB (8941): mxb/tda9840: cleanups, use module saa7115 instead of
 saa7111.

Cleanup tda9840 and use a v4l2 API to get the tuner subchannels.
Do some cleanups in mxb and switch to saa7115 instead of the saa7111
module.

From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 08:31:13 -0300
Subject: V4L/DVB (8943): saa5246a: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

Subject: V4L/DVB (8944): saa5249: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

Subject: V4L/DVB (8946): dib7000m: fix powerpc build error

The dib7000m_i2c_enumeration() function is not used by any public drivers,
however some prototype board use it. So '#if 0' for now, but don't remove it.

Thanks to Patrick Boettcher for clarifying this.

Subject: V4L/DVB (8950): xc5000: prevent an OOPS if analog driver is unloaded
 while digital is in use

Prevent an OOPS if xc5000_attach was called by tuner.ko before being called by
the DVB adapter driver. The OOPS occurs when a digital tune request is made
after tuner.ko is unloaded.

When tuner.ko is unloaded, it takes the xc5000_config structure with it.

Rather than storing a pointer to the xc5000_config structure, just store the
if_khz and tuner_callback inside the xc5000_priv internal state structure.

Subject: V4L/DVB (8951): xc5000: dont pass devptr in xc5000_attach()

Dont pass devptr in xc5000_attach, dont store it in xc5000_priv.
This pointer is passed into the tuner_callback function, which always
expects a pointer to fe->dvb->priv or i2c_adapter->algo_data.

This prevents future possible bugs in new drivers, such as using a "devptr"
other that the standard fe->dvb->priv in a DVB driver.

Subject: V4L/DVB (8956): bttv: Turn video_nr, vbi_nr and radio_nr into arrays

With video_nr, vbi_nr and radio_nr being simple integers, it is not
possible to use these parameters on a system with multiple bttv
adapters (which happens to be my case.) video_register_device() will
always fail on the second and later adapters. Turn these parameters
into arrays, as many other V4L drivers are already doing, so that they
can be used on such systems.

Subject: V4L/DVB (8985): S2API: Added dvb frontend changes to support a newer
 tuning API

This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.

The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.

known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.

This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

For testing and exercise purposes, see the latest tune.c tool
available from http://www.steventoth.net/linux/s2

Subject: V4L/DVB (8988): S2API: Allow the properties to call legacy ioctls

SET_TONE and SET_VOLTAGE were not previously implemented. Two options
existed. Either cut/paste from the previous ioctl handler into the
process_properties function, which is code duplication. Or, split
the current ioctl handler into it's two major pieces.

Piece 1, responsible for input validation and semaphore acquiring
Piece 2 the processing of the previous ioctls

and finally, a new third pieces where the array of properties
is processed, and can freely call the legacy ioctl handler without
having to re-acquire the fepriv->sem semaphore. This is a clean approach
and ensures the existing legacy ioctls are processed as they were previously
(but with an extra function call) and allows the new API to share code
without duplication.

From e7fee0f3aa111d42cdcfc1470cfdc21dde0cdbe2 Mon Sep 17 00:00:00 2001
From: Steven Toth <stoth@linuxtv.org>
Date: Thu, 11 Sep 2008 10:23:01 -0300
Subject: V4L/DVB (8996): S2API: typedefs replaced, _SEQ_'s removed, fixed 16
 command arrays replaced

After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
   switch to a flexible variable length API. For practical reasons
   a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
   of commands.

tune-v0.0.3.c is required to use this API, it contains the interface changes.

Subject: V4L/DVB (8999): S2API: Reduce demod driver complexity by using a
 cache sync

For demod drivers, we want a single tuning function (set_frontend) to have
access to the properly constructed dvb_frontend_parameters structure, or
the cache values - regardless of whether the legacy or new API is being used.

This cuts down on redundant code in the demod drivers and ensures the
tuning parameters are consistent regardless of the API entry type.

From 363429a089590f3f4071ebc492b3712fdcba770b Mon Sep 17 00:00:00 2001
From: Steven Toth <stoth@linuxtv.org>
Date: Fri, 12 Sep 2008 01:34:28 -0300
Subject: V4L/DVB (9003): S2API: Remove the DTV_SET_ and DTV_GET_ prefixes

The API now assumes that ioctl calls for FE_SET_PROPERTY and all
set commands, and FE_GET_PROPERTY are get commands.

Simplification.

Subject: V4L/DVB (9004): S2API: Implement GET/SET handing to the demods

The frontends will be notified (if they chose) of all _get and _set commands
so they can help determine result or action. Results are now returned
to userspace correctly.

From 490c868408bc57a756550148313ac8582fe501ef Mon Sep 17 00:00:00 2001
From: Darron Broad <darron@kewl.org>
Date: Sat, 13 Sep 2008 19:42:16 -0300
Subject: V4L/DVB (9011): S2API: A number of cleanusp from the last 24 months.

I was given these changes by Darron Broad and Igor Liplianin and represent a series
of patches they've been making to the cx24116 driver over the last two years.

Changes for handling symbolrates >30Ksps
Tone handling changes.
Diseqc support.
Sleep support, shutting down the clocks correctly.
Cleanup on ROLL_OFF and PILOT support.

*** ST - We need to cleanup the sysclt control, this is abnormal
    in a demod driver. We should work towards understanding the missing
    API's and ensure we have them in S2API.  ***

Subject: V4L/DVB (9014): History update: MPEG initialization in cx24116.

Adjust MPEG initialization in cx24116 in order to accomodate different
MPEG CLK position and polarity in different cards. For example, HVR4000
uses 0x02 value, but DvbWorld & TeVii USB cards uses 0x01. Without it MPEG
stream was broken on that cards for symbol rates > 30000 kSyms/s.

Subject: V4L/DVB (9016): HVR3000/4000 Hauppauge related IR cleanups

From the author:
This patch-set fixes remote control issues I have experienced
with hauppauge drivers in Linux since the PVR-350 and now
with both a NOVA-S+ and HVR-4000. It has also been confirmed
to work with an HVR-1300 user who had exactly the same issue.

Hauppage remote controls use RC5. RC5 has a bit-field which
represents the target device. The hauppauge windows drivers
have a registry key which can enable filtering, but the linux
drivers will accept any target device in this bit field for
internal processing.

This causes problems with setups such as mythtv where remote
control key presses destined for the TV (target = 0) are
interpreted by the kernel and subsequenctly LIRC then mythtv.

Of the remote controls I have to hand (wintv black, pvr/hvr
silver) the hauppauge remotes send one of two device targets
ids, these are interpreted by the patch which then filters
out any non hauppauge addresses.

Subject: V4L/DVB (9025): S2API: Deactivate the ISDB-T definitions

We don't want to push the ISDB-T definitions into the kernel until
we have a high level of confidence in the ISDB-T API. More testing
is required before this code is released.

Subject: V4L/DVB (9028): saa7134: add support for the triple Asus Tiger 3in1

after looking it up, all rants about the 80 columns restriction seem to
be in vain. After changing the card's name it are now "only" seven new
lines in the tiny DVB-T/DVB-S switch function.

DVB: registering new adapter (saa7133[0])
DVB: registering frontend 0 (Philips TDA10086 DVB-S)...

The board init gpio is 0x0, 0x200000 is from previously unloading with
antenna_switch = 1.

It needs firmware for the tda10046 and analog sound needs saa7134-alsa.

I have support for one more board and need to fix the first revision of
the Asus Tiger DVB-T hybrid. DVB-T currently hangs on the male radio
antenna input, also some small other stuff.

Please report any issues with this patch, the next are depending on this
one.

Subject: V4L/DVB (9031): uvcvideo: Fix incomplete frame drop when switching to
 a variable size format.

When streaming in a fixed size format the driver sets a flag in the uvc_queue
structure to drop incomplete incoming frames. The flag wasn't cleared when
switching to a variable size format, which resulted in a broken
'MJPEG after YUV'.

Subject: V4L/DVB:usbvideo:don't use part of buffer for USB transfer #4

The status[] is part of  uvc_device structure. We can't make sure
the address of status is at a cache-line boundary in all archs,so
status[] might share a cache-line with some fields in uvc_structure.
This can lead to some cache coherence issues(http://lwn.net/Articles/2265/).
Use dynamically allocated buffer instead.

Subject: V4L/DVB (9034): With the recent patch to v4l2 titled "v4l2: use
 register_chrdev_region

instead of register_chrdev", the internal reference count is no longer
necessary in order to free the internal stk_webcam struct. This patch
removes the reference counter from the stk_webcam struct and frees the
struct via the video_device release callback. It also fixes an
associated bug in stk_camera_probe which could result from
video_unregister_device being called before video_register_device.
Lastly, it simplifies access to the stk_webcam struct in several
places. This patch should apply cleanly against the "working" branch
of the v4l-dvb git repository.

This patch is identical to the patch I sent a couple of months back
titled "stk-webcam: Fix video_device handling" except that it has been
rebased against current modifications to stk-webcam and it no longer
depends on any other outstanding patches.

Subject: V4L/DVB (9036): uvcvideo: Fix control cache access when setting
 composite auto-update controls

Auto-update controls are never marked is loaded to prevent uvc_get_ctrl from
loading the control value from the cache. When setting a composite (mapped to
several V4L2 controls) auto-update UVC control, the driver updates the control
cache value before processing each V4L2 control, overwriting the previously
set V4L2 control.

This fixes the problem by marking all controls as loaded in uvc_set_ctrl
regardless of their type and resetting the loaded flag in uvc_commit_ctrl for
auto-update controls.

Thanks to Ilia Penev for the tip-off that this device is much the same as
(identical to?) a Terratec Cinergy HT USB XE, and for the firmware hints:
http://linuxtv.org/pipermail/linux-dvb/2008-August/028108.html

DVB functionality tested OK with xine using the usual dib0700 firmware.

This diff is based on the latest latest linuxtv.org v4l-dvb mercurial

Subject: V4L/DVB (9039): Add support for new i2c API provided in firmware
 version 1.20

The Pinnacle PCTV HD Pro has an xc5000, which exposed a bug in the dib0700's
i2c implementation where it did not properly support a single i2c read request
(sending it as an i2c write request instead).  Version 1.20 of the firmware
added support for a new i2c API which supported such requests.

This change defaults to fw 1.20 for all devices, but does not default to using
the new i2c API (since initial testing suggests problems interacting with the
mt2060).  Maintainers can enable the use of the new i2c API by putting
the following into their frontend initialization:

struct dib0700_state *st = adap->dev->priv;
st->fw_use_new_i2c_api = 1;

Also note that the code expects i2c repeated start to be supported.  If the
i2c slave does not support repeated start, i2c messsages should have the
I2C_M_NOSTART flag set.

Thanks to Patrick Boettcher <patrick.boettcher@desy.de> for providing new
firmware fixing the issue as well as example i2c code utilizing the interface.

Subject: V4L/DVB (9040): TTUSB-DEC DVB-S: claim to have lock

As reported by BOUWSMA Barry the readout of the signal status doesn't work
on dec3000-s models. Since we don't know how to do it better, revert back
to the old behaviour and always report a signal lock.

Subject: V4L/DVB (9046): Add support for Non-Pro version of Pinnacle PCTV HD
 USB Stick

Add USB ID for Pinnacle PCTV HD USB Stick.  According to the USB trace and
photos, the only difference is the removal of the port for the analog
S-video/audio input.

Thanks to Mike Pringle <oblongd@gmail.com> for providing the USB trace of the
device starting up, and testing the support.

Subject: V4L/DVB (9047): [PATCH] Add remote control support to Nova-TD (52009)

This patch adds remote control support for the Hauppauge WinTV Nova-TD
(Diversity) model. (That's the 52009 version.) It also adds the
key-codes for the credit-card style remote control that comes with
this particular adapter.

Subject: V4L/DVB (9048): add a general-purpose callback pointer to struct
 dvb_frontend

Remove tuner_callback pointers from tuner driver configuration
and private state structures, replaced with a general-purpose
callback pointer within struct dvb_frontend.

A new parameter is added to the callback function, called
component. This allows us to use this callback pointer by
frontend components other than the tuner, if need be. So
far, this is only used by tuner drivers.

Subject: V4L/DVB (9051): dib0700: use dvb_frontend->callback for xc5000 gpio
 reset

The tuner_callback function pointer from struct xc5000_config has been removed.
Use dvb_frontend->callback instead.

Also, mark function dib0700_xc5000_tuner_callback as static int.

Subject: V4L/DVB (9055): tuner-xc2028: Do a better job selecting firmware type

Firmware selection is very tricky on this device. This patch do a better
selection of the proper firmware type, by using a code to hint if the
firmware to be loaded should be D2620 or D2633.

It also allows overriding the hint at the control structure.

Subject: V4L/DVB (9066): Pinnacle Hybrid PCTV Pro (pctv310c) DVB-T support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch against latest mercurial makes DVB-T working on Pinnacle
Hybrid PCTV Pro (pctv310c).

In cx88-dvb.c, a specific zl10353_config is created with the if2
inferred from the old comment in the currently used config. It is then
used for attach, and i2c_gate_ctrl is set to NULL.

The entry in cx88-cards.c is modified with GPIO gathered from windows
with regspy, and DVB enabled. The frontend is set to
XC3028_FE_ZARLINK456 to match the zl10353_config.

It is working great with the freeview channels I can receive.

Subject: V4L/DVB (9069): cx88: Bugfix: all client disconnects put the frontend
 to sleep.

From the author:

"This fixes the problem where previously all client disconnects
put the analogue frontend into standby.

In the following example, the first command is succesfully
watching TV but the second command which returns EBUSY
detunes the receiver by entering it into the standby state.

tvtime -d /dev/video0 &
cat /dev/video0
"

Date: Mon, 29 Sep 2008 05:57:32 -0300
Subject: V4L/DVB (9087): gspca: Image transfer by bulk uses altsetting 0 with
 any buffer size.

- gspca_dev field 'bulk_size' added.
- when only one altsetting usable, do image transfer by bulk.

Subject: V4L/DVB (9091): gspca: Subdriver m5602 (ALi) added.

This patch adds support for the ALi m5602 usb bridge and is based on
the gspca framework.
It contains code for communicating with 5 different sensors:
OmniVision OV9650, Pixel Plus PO1030, Samsung S5K83A, S5K4AA and
finally Micron MT9M111.

+This driver mimics the windows drivers, which have a braindead implementation sending bayer-encoded frames at VGA resolution.
+In a perfect world we should be able to reprogram the m5602 and the connected sensor in hardware instead, supporting a range of resolutions and pixelformats

 radio devices

This patch creates a new usb-radio driver, radio-mr800.c, that
supports the AverMedia MR 800 USB FM radio devices.
This device plugs into both the USB and an analog audio input, so this
thing only deals with initialization and frequency setting, the audio
data has to be handled by a sound driver.

+ *
+ * Many things to do:
+ * 	- Correct power managment of device (suspend & resume)
+ * 	- Make x86 independance (little-endian and big-endian stuff)
+ * 	- Add code for scanning and smooth tuning
+ * 	- Checked and add stereo&mono stuff
+ * 	- Add code for sensitivity value
+ * 	- Correct mistakes
+ * 	- In Japan another FREQ_MIN and FREQ_MAX

Subject: V4L/DVB (9110): cx18: Add default behavior of checking and retrying
 PCI MMIO accesses

cx18: Add default behavior of checking and retrying PCI MMIO accesses.
The concept of checking and retrying PCI MMIO accesses for better reliability
in older motherboards was suggested by Steve Toth <stoth@linuxtv.org>.  This
change implements MMIO retries and the retry_mmio module parameter that is
enabled by default.  Limited experiments have shown this is more reliable than
the mmio_ndelay parameter.  mmio_ndelay has insignificant effect with retries
enabled.

Subject: V4L/DVB (9111): cx18: Up the version to 1.0.1

cx18: Up the version to 1.0.1.  This will make it easy to tell if retries
of MMIO access are implemented or not in trouble reports.  First course of
action for I2C and other initialization problem reports will be to have user
upgrade to v1.0.1 of driver.

Subject: V4L/DVB (9113): saa7134: fixes for the Asus Tiger Revision 1.00

In opposite to the P7131 Dual this early OEM card has a male
radio antenna connector and also no remote.

We currently switch the DVB-T RF feed to the radio input, like
on the P7131 with female radio connector used also for DVB-T
and should improve this.

 dib0700_xc5000_tuner_callback after return call

Put callback definition before function return and cleanup callback:

Fix a bug where the xc5000 callback was being set *after* the
return call (essentially resulting in dead code).

Also cleanup the callback function to detect unknown commands.

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.

cx18: Add entries for the Leadtek PVR2100 and Toshiba Qosmio DVB-T/Analog
capture cards.  Both cards are hybrids cards, but no digital capture
functionality has been added yet.  These entries are a first guess at the card
entries to get analog working, given the information available.  Terry Wu
<terrywu at leadtek.com.tw> provided a pointer to information for the PVR2100.
Martin Juhl <mj at casalogic.dk>, an owner of the Toshiba DVB-T/Analog tuner
card, provided the DDR timing information from his Windows inf file.

cx18: Fix warning message for DMA done notification for inactive stream.  The
warning message would always gripe that the radio stream was to blame, which
was misleading and wrong (/dev/radioN nodes never transfer data).

Subject: V4L/DVB (9133): v4l: disconnect kernel number from minor

The v4l core creates four different video devices (video, vbi, radio, vtx)
and each has its own range of minor numbers. However, modern devices keep
increasing the number of devices that they need so a maximum of 64 video
devices will not be enough in the future. In addition this scheme makes
it very hard to add new device types.

This patch disconnects the kernel number allocation (e.g. video0, video1,
etc.) from the actual minor number (just pick the first free minor).

This allows for much more flexibility in the future. However, it does
require the use of udev. For those who cannot use udev a new CONFIG option
was created that changes the allocation scheme back to the old behavior.

Thanks to Greg KH for suggesting this approach during the 2008 LPC.

In addition, several bugs were fixed in the ivtv and cx18 drivers: these
drivers try to allocate specific kernel numbers but that scheme contained
a bug which caused what should have been e.g. video17 to appear as e.g.
video2.

Subject: V4L/DVB (9135): cx88 Dvico FusionHDTV Pro

Well, one thing you encouraged me to do was re-test some of my cards
which contained the xc3028-zarlink combo.

Which led me to test a Dvico FusionHDTV Pro.

Almost a year ago, Chris Pascoe did a patch for this which can be found
at his ~pascoe/xc-test at Linuxtv.
This worked very well, however that was using his version of firmware.

Alas, someone attempted to use this and patch v4l-dvb, and messed it up.
So I've fixed it.
I enclose the patch against today's tree (containing your latest
tuner-xc2028.c patch).

The card now works very well, well with DVB-T anyway.

Subject: V4L/DVB (9129): zoran: move zoran sources into a zoran subdirectory

Prevent the zoran driver sources from cluttering the video directory.
This changeset only moves the drivers and it does not fix any of the
checkpatch warnings/errors to keep the changeset clean.

-/* general description */
-/* =================== */

-/* Should ease the (re-)usage of drivers supporting cards with (different)
-   video codecs. The codecs register to this module their functionality,
-   and the processors (masters) can attach to them if they fit.
-
-   The codecs are typically have a "strong" binding to their master - so I
-   don't think it makes sense to have a full blown interfacing as with e.g.
-   i2c. If you have an other opinion, let's discuss & implement it :-)))
-
-   Usage:
-
-   The slave has just to setup the videocodec structure and use two functions:
-   videocodec_register(codecdata);
-   videocodec_unregister(codecdata);
-   The best is just calling them at module (de-)initialisation.
-
-   The master sets up the structure videocodec_master and calls:
-   codecdata=videocodec_attach(master_codecdata);
-   videocodec_detach(codecdata);
-
-   The slave is called during attach/detach via functions setup previously
-   during register. At that time, the master_data pointer is set up
-   and the slave can access any io registers of the master device (in the case
-   the slave is bound to it). Otherwise it doesn't need this functions and
-   therfor they may not be initialized.
-
-   The other fuctions are just for convenience, as they are for sure used by
-   most/all of the codecs. The last ones may be ommited, too.
-
-   See the structure declaration below for more information and which data has
-   to be set up for the master and the slave.
-
-   ----------------------------------------------------------------------------
-   The master should have "knowledge" of the slave and vice versa.  So the data
-   structures sent to/from slave via set_data/get_data set_image/get_image are
-   device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

-/*
-   ==== master setup ====
-   name -> name of the device structure for reference and debugging
-   master_data ->  data ref. for the master (e.g. the zr36055,57,67)
-   readreg -> ref. to read-fn from register (setup by master, used by slave)
-   writereg -> ref. to write-fn to register (setup by master, used by slave)
-	       this two functions do the lowlevel I/O job
-
-   ==== slave functionality setup ====
-   slave_data -> data ref. for the slave (e.g. the zr36050,60)
-   check -> fn-ref. checks availability of an device, returns -EIO on failure or
-	    the type on success
-	    this makes espcecially sense if a driver module supports more than
-	    one codec which may be quite similar to access, nevertheless it
-	    is good for a first functionality check
-
-   -- main functions you always need for compression/decompression --
-
-   set_mode -> this fn-ref. resets the entire codec, and sets up the mode
-	       with the last defined norm/size (or device default if not
-	       available) - it returns 0 if the mode is possible
-   set_size -> this fn-ref. sets the norm and image size for
-	       compression/decompression (returns 0 on success)
-	       the norm param is defined in videodev.h (VIDEO_MODE_*)
-
-   additional setup may be available, too - but the codec should work with
-   some default values even without this
-
-   set_data -> sets device-specific data (tables, quality etc.)
-   get_data -> query device-specific data (tables, quality etc.)
-
-   if the device delivers interrupts, they may be setup/handled here
-   setup_interrupt -> codec irq setup (not needed for 36050/60)
-   handle_interrupt -> codec irq handling (not needed for 36050/60)
-
-   if the device delivers pictures, they may be handled here
-   put_image -> puts image data to the codec (not needed for 36050/60)
-   get_image -> gets image data from the codec (not needed for 36050/60)
-		the calls include frame numbers and flags (even/odd/...)
-		if needed and a flag which allows blocking until its ready

-   Currently there is only a information display planned, as the layer

-   Information is available via procfs. The current entry is "/proc/videocodecs"

+
+/* Should ease the (re-)usage of drivers supporting cards with (different)
+   video codecs. The codecs register to this module their functionality,
+   and the processors (masters) can attach to them if they fit.
+
+   The codecs are typically have a "strong" binding to their master - so I
+   don't think it makes sense to have a full blown interfacing as with e.g.
+   i2c. If you have an other opinion, let's discuss & implement it :-)))
+
+   Usage:
+
+   The slave has just to setup the videocodec structure and use two functions:
+   videocodec_register(codecdata);
+   videocodec_unregister(codecdata);
+   The best is just calling them at module (de-)initialisation.
+
+   The master sets up the structure videocodec_master and calls:
+   codecdata=videocodec_attach(master_codecdata);
+   videocodec_detach(codecdata);
+
+   The slave is called during attach/detach via functions setup previously
+   during register. At that time, the master_data pointer is set up
+   and the slave can access any io registers of the master device (in the case
+   the slave is bound to it). Otherwise it doesn't need this functions and
+   therfor they may not be initialized.
+
+   The other fuctions are just for convenience, as they are for sure used by
+   most/all of the codecs. The last ones may be ommited, too.
+
+   See the structure declaration below for more information and which data has
+   to be set up for the master and the slave.
+
+   ----------------------------------------------------------------------------
+   The master should have "knowledge" of the slave and vice versa.  So the data
+   structures sent to/from slave via set_data/get_data set_image/get_image are
+   device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

+   ==== master setup ====
+   name -> name of the device structure for reference and debugging
+   master_data ->  data ref. for the master (e.g. the zr36055,57,67)
+   readreg -> ref. to read-fn from register (setup by master, used by slave)
+   writereg -> ref. to write-fn to register (setup by master, used by slave)
+	       this two functions do the lowlevel I/O job
+
+   ==== slave functionality setup ====
+   slave_data -> data ref. for the slave (e.g. the zr36050,60)
+   check -> fn-ref. checks availability of an device, returns -EIO on failure or
+	    the type on success
+	    this makes espcecially sense if a driver module supports more than
+	    one codec which may be quite similar to access, nevertheless it
+	    is good for a first functionality check
+
+   -- main functions you always need for compression/decompression --
+
+   set_mode -> this fn-ref. resets the entire codec, and sets up the mode
+	       with the last defined norm/size (or device default if not
+	       available) - it returns 0 if the mode is possible
+   set_size -> this fn-ref. sets the norm and image size for
+	       compression/decompression (returns 0 on success)
+	       the norm param is defined in videodev.h (VIDEO_MODE_*)
+
+   additional setup may be available, too - but the codec should work with
+   some default values even without this
+
+   set_data -> sets device-specific data (tables, quality etc.)
+   get_data -> query device-specific data (tables, quality etc.)
+
+   if the device delivers interrupts, they may be setup/handled here
+   setup_interrupt -> codec irq setup (not needed for 36050/60)
+   handle_interrupt -> codec irq handling (not needed for 36050/60)
+
+   if the device delivers pictures, they may be handled here
+   put_image -> puts image data to the codec (not needed for 36050/60)
+   get_image -> gets image data from the codec (not needed for 36050/60)
+		the calls include frame numbers and flags (even/odd/...)
+		if needed and a flag which allows blocking until its ready

+ *       I don't understand why many other drivers first allocate them with

+ *       On big-endian architectures (such as ppc) some extra steps

+ *       endian values. The use of cpu_to_le32() and le32_to_cpu()
+ *       in this function (and one or two others in zoran_device.c)
+ *       ensure that these values are always stored in little-endian
+ *       form, regardless of architecture. The zr36057 does Very Bad

- *       On big-endian architectures (such as ppc) some extra steps

- *       endian values. The use of cpu_to_le32() and le32_to_cpu()
- *       in this function (and one or two others in zoran_device.c)
- *       ensure that these values are always stored in little-endian
- *       form, regardless of architecture. The zr36057 does Very Bad

From f9b9796ade7609cd62571d38f064e20c77d31281 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Sat, 13 Sep 2008 09:36:06 -0700
Subject: Add a script to visualize the kernel boot process / time

When optimizing the kernel boot time, it's very valuable to visualize
what is going on at which time. In addition, with some of the initializing
going asynchronous soon, it's valuable to track/print which worker thread
is executing the initialization.

This patch adds a script to turn a dmesg into a SVG graph (that can be
shown with tools such as InkScape, Gimp or Firefox) and a small change
to the initcall code to print the PID of the thread calling the initcall
(so that the script can work out the parallelism).

Subject: fastboot: fix issues and improve output of bootgraph.pl

David Sanders reported some issues with bootgraph.pl's display
of his sytems bootup; this commit fixes these by scaling the graph
not from 0 - end time but from the first initcall to the end time;
the minimum display size etc also now need to scale with this, as does
the axis display.

The regexp used to match the start and the end of an initcall

a number in them. This patch is fixing that.

Subject: fastboot: make the raid autodetect code wait for all devices to init

The raid autodetect code really needs to have all devices probed before
it can detect raid arrays; not doing so would give rather messy situations
where arrays would get detected as degraded while they shouldn't be etc.

This is in preparation of removing the "wait for everything to init"
code that makes everyone pay, not just raid users.

As requested/suggested by Neil Brown: make the raid code print that it's
about to wait for probing to be done as well as give a suggestion on how
to disable the probing if the user doesn't use raid.

also, use the opportunity to put the RAID autodetection code

Subject: raid: make RAID autodetect default a KConfig option

RAID autodetect has the side effect of requiring synchronisation
of all device drivers, which can make the boot several seconds longer
(I've measured 7 on one of my laptops).... even for systems that don't
have RAID setup for the root filesystem (the only FS where this matters).

This patch makes the default for autodetect a config option; either way
the user can always override via the kernel command line.

Subject: powerpc/xics: EOI unmapped irqs after disabling them

When reciving an irq vector that does not have a linux mapping, the kernel
prints a message and calls RTAS to disable the irq source.   Previously
the kernel did not EOI the interrupt, causing the source to think it is
still being processed by software.  While this does add an additional
layer of protection against interrupt storms had RTAS failed to disable
the source, it also prevents the interrupt from working when a driver
later enables it.  (We could alternatively send an EOI on startup, but
that strategy would likely fail on an emulated xics.)

All interrupts should be disabled when the kernel starts, but this can
be observed if a driver does not shutdown an interrupt in its reboot
hook before starting a new kernel with kexec.

Michael reports this can be reproduced trivially by banging the keyboard
while kexec'ing on a P5 LPAR: even though the hvc_console driver request's
the console irq later in boot, the console is non-functional because
we're receiving no console interrupts.

Subject: powerpc/xics: Update default_server during migrate_irqs_away

Currently, every time we determine which irq server to use, we check if
default_server, which is the id of the bootcpu, is still online.  But
default_server is a hardware cpu, not the logical cpu id needed to index
cpu_online_map.

Since the default server can only go offline during a cpu hotplug event,
explicitly check the default server and choose the new one when we move
irqs away from the cpu being offlined.

This has the added benefit of only needing the boot_cpuid to be updated
and not relying on the cpu being marked offline during migrate_irqs_away.

Also, since xics_update_irq_servers only reads device tree information, we
can call it before xics_init_host in xics_init_IRQ and then default_server
will always be valid when we can reach get_irq_server via the host ops.

Subject: ALSA: ASoC: Allow machine drivers to mark pins as not connected

Add a new API call snd_soc_dapm_nc_pin() which allows machine drivers to
mark pins as being permanently disabled.  At present this is identical
to snd_soc_dapm_disable_pin() except in terms of improving the internal
documentation of machine drivers that use it.  The intention is that in
future it will be extended to provide additional features such as hiding
controls that are only relevant to paths using the disconnected pin.

Subject: ALSA: ASoC: Remove references to Endrelia ETI-B1 board

The ASoC machine drivers for this board were only provided as examples
for the new AT91 ASoC platform driver.  Since the ETI-B1 board is
proprietary and there are other AT91 ASoC machine drivers available,
it makes sense to remove these drivers.

Subject: ALSA: ASoC Blackfin: fix bug - Audio Latency on AD1981 with MMAP
 enabled

With MMAP enabled (DMA mode) on the AD1981, there is +/- 250ms of delay between
writing data to alsa and audio starts coming out of the AD1981.

Copy more data to local buffer before starting DMA

Subject: ALSA: ASoC: Add WM8753 SPI support

Implement SPI support for WM8753, cut'n'pasting from the support for
WM8731 contributed by Cliff Cai and Alan Horstmann since the wire format
is the same for both codecs.

Subject: ALSA: ASoC: Implement WM8510 bias level control

The WM8510 bias level configuration blindly overwrites the power
management registers, interfering with the operation of DAPM.
Only adjust the specific bits required, implementing use of the VMID
resistor string configuration control as we go.

Subject: ALSA: ASoC: Make WM8510 microphone input a DAPM mixer

The WM8510 microphone input PGA was represented as a DAPM PGA but in
DAPM terms the functionality is that of a mixer since it takes three
switchable inputs and produces one output. Representing it as an input
was causing its controls to be misinterpreted as gain controls and
would cause some required DAPM updates to be missed.

Subject: ALSA: ASoC: Make TLV320AIC26 user-visible

The TLV320AIC26 Kconfig option is unusual in that it supports the
OpenFirmware machine driver which doesn't have a hard binding to the
codec driver but discovers the codec via the device tree.  This makes it
meaningful to select the codec without a machine driver.

Ideally there would be a proxy entry so that this option was only
visible on OpenFirmware systems.

Subject: ALSA: ASoC: Drop device registration from GTA01 lm4857 driver

Device registration should be handled at the machine level and not
in the driver code itself.  This patch removes the device registration
from the driver code in preparation for moving it to the machine
definition.

[Squashed down two parts to this patch for bisectability - there's also
a third part adding registration of the device to the out of tree GTA01
machine driver -- broonie]

Subject: md: Fix rdev_size_store with size == 0

Fix rdev_size_store with size == 0.
size == 0 means to use the largest size allowed by the
underlying device and is used when modifying an active array.

This fixes a regression introduced by
 commit d7027458d68b2f1752a28016dcf2ffd0a7e8f567

Subject: md: Allow metadata_version to be updated for externally managed
 metadata.

For externally managed metadata, the 'metadata_version' sysfs
attribute is really just a channel for user-space programs to
communicate about how the array is being managed.
It can be useful for this to be changed while the array is active.

Normally changes to metadata_version are not permitted while the array
is active.  Change that so that if the metadata is externally managed,
the metadata_version can be changed to a different flavour of external
management.

Subject: md: Don't try to set an array to 'read-auto' if it is already in that
 state.

'read-auto' is a variant of 'readonly' which will switch to writable
on the first write attempt.

Calling do_md_stop to set the array readonly when it is already readonly
returns an error.  So make sure not to do that.

Date: Mon, 13 Oct 2008 11:55:12 +1100
Subject: md: Convert remaining 1k representations in linear.c to sectors.

This patch renames hash_spacing and preshift to  spacing and
sector_shift respectively with the following change of semantics:

Case 1: (sizeof(sector_t) <= sizeof(u32)).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In this case, we have sector_shift = preshift = 0 and spacing =
2 * hash_spacing.

Hence, the index for the hash table which is computed by the new code
in which_dev() as sector / spacing equals the old value which was
(sector/2) / hash_spacing.

Note also that the value of nb_zone stays the same because both sz
and base double.

Case 2: (sizeof(sector_t) > sizeof(u32)).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(aka the shifting dance case). Here we have sector_shift = preshift +
1 and

spacing = 2 * hash_spacing

during the computation of nb_zone and curr_sector, but

spacing = hash_spacing

in which_dev() because in the last hunk of the patch for linear.c we
shift down conf->spacing (= 2 * hash_spacing) by one more bit than
in the old code.

Hence in the computation of nb_zone, sz and base have the same value
as before, so nb_zone is not affected. Also curr_sector in the next
hunk stays the same.

In which_dev() the hash table index is computed as

(sector >> sector_shift) / spacing

In view of sector_shift = preshift + 1 and spacing = hash_spacing,
this equals

((sector/2) >> preshift) / hash_spacing

which is the value computed by the old code.

Subject: md: remove space after function name in declaration and call.

Having
   function (args)
instead of
   function(args)

make is harder to search for calls of particular functions.
So remove all those spaces.

From 4bbf3771ca40d0aaec8316d0e7476b16010288e5 Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.de>
Date: Mon, 13 Oct 2008 11:55:12 +1100
Subject: md: Relax minimum size restrictions on chunk_size.

Currently, the 'chunk_size' of an array must be at-least PAGE_SIZE.

This makes moving an array to a machine with a larger PAGE_SIZE, or
changing the kernel to use a larger PAGE_SIZE, can stop an array from
working.

For RAID10 and RAID4/5/6, this is non-trivial to fix as the resync
process works on whole pages at a time, and assumes them to be wholly
within a stripe.  For other raid personalities, this restriction is
not needed at all and can be dropped.

So remove the test on chunk_size from common can, and add it in just
the places where it is needed: raid10 and raid4/5/6.

Subject: r8169: NULL pointer dereference on r8169 load

mmio_addr in r8169 needs to be initialized before use

Maybe that all tp-> initialization should be moved before rtl_init_mac_address call,
but this is enough to get rid of crash in rtl_rar_set due to mmio_addr being uninitialized.

Subject: sky2: Fix WOL regression

Since dev->power.should_wakeup bit is used by the PCI core to
decide whether the device should wake up the system from sleep
states, set/unset this bit whenever WOL is enabled/disabled using
sky2_set_wol().

Remove an open-coded reference to the standard PCI PM registers that
is not used any more.

Subject: powerpc/xics: Consolidate ipi message encode and decode

xics supports only one ipi per cpu, and expects software to use some
queue to know why the interrupt was sent.  In Linux, we use a an array
of bitmaps indexed by cpu to identify the message.  Currently the bits
are set in smp.c and decoded in xics.c, with the data structure in a
header file.   Consolidate the code in xics.c similar to mpic and other
interrupt controllers.

Also, while making the the array static, the message word doesn't need
to be volatile as set_bit and test_clear_bit take care of it for us, and
put it under ifdef smp.

From 0641cc91b08937578263589feb15182b9ad2b0fc Mon Sep 17 00:00:00 2001
From: Milton Miller <miltonm@bga.com>
Date: Fri, 10 Oct 2008 01:56:30 +0000
Subject: powerpc/xics: Rearrange file to group code by function

Now that xics_update_irq_servers is called only from init and hotplug
code, it becomes possible to clean up the ordering of functions in the
file, grouping them but the interfaces they implement.

Subject: powerpc/xics: Change *_xirr_info_set() prototype to avoid casts

The xirr is 32 bits in hardware, but the hypervisor requries the upper
bits of the register to be clear on the hcall.  By changing the type
from signed to unsigned int we can drop masking it back to 32 bits.

Trim unneeded includes from xics.c.  We don't use signals or gfp
flags, we use only OF functions and don't need prom, and the 8259

Subject: powerpc/xics: Initialization code cleanups

We only need to check the ibm,interrupt-server#-size property once, not
once per global server and thread.

We can use !CONFIG_SMP cpu masks and hard_smp_processor_id() to avoid an ifdef.
Put the node when breaking out of the loop on lpar systems.

Subject: powerpc/xics: Factor out cpu joining/unjoining the GIQ

This factors out processors joining and unjoining the Global Interrupt
Queue into a separate function.

There is a bit of math to calculate the arguments to rtas to join
or leave the global interrupt queue, and a warning on failure
afterwards.  Make a helper for the 3 callers.

Subject: powerpc/xics: EOI xics ipi by hand in kexec

EOI normally has the side effect of returning the cpu to the base
priority to recieve the next interrupt.  This is actually controlled
by the top byte of the xirr register.   When we are exiting the
kernel in kexec we must eoi the ipi for the next kernel because we
never return from the handler, but we want to leave interrupt
delivery blocked until the next kernel takes action.

Since the hardware ipi vector is fixed, its easiest to just do the
eoi explicitly.

A single full sync (mb()) is requrired to order the mmio to the qirr reg
with the set or clear of the message word.  However, test_and_clear_bit
has the effect of smp_mb() and we are not doing any other io from here,
so we don't need a mb per bit processed.

The comment in the code was asking "Do we have to do this?", and according
to x86 and s390 the answer is no, the scheduler will do it before calling
the arch hook.

Subject: net/mac80211/rx.c: fix build error

older versions of gcc do not recognize that ieee80211_rx_h_mesh_fwding()
is unused when CONFIG_MAC80211_MESH is disabled:

  net/built-in.o: In function `ieee80211_rx_h_mesh_fwding':
  rx.c:(.text+0xd89af): undefined reference to `mpp_path_lookup'
  rx.c:(.text+0xd89c6): undefined reference to `mpp_path_add'

as this code construct:

        if (ieee80211_vif_is_mesh(&sdata->vif))
                CALL_RXH(ieee80211_rx_h_mesh_fwding);

still causes ieee80211_rx_h_mesh_fwding() to be linked in.

Protect these places with an #ifdef.

commit b0dee578 ("Fix modpost failure when rx handlers are not inlined.")
solved part of this problem - this patch is still needed.

Commit e545a6140b698b2494daf0b32107bdcc5e901390 ("kernel/cpu.c: create
a CPU_STARTING cpu_chain notifier") added a notify_cpu_starting()
notifier event, and hit every arch except sparc64.

Fix that missed case.

Subject: chmc: Mark %ver register inline asm with __volatile__

Otherwise GCC can try to do the register read before the guarding test
on us3mc_platform() being true.

If that happens we can take an exception, because %ver register reads
are not allowed in privileged more on hypervisor platforms.

Subject: V4L/DVB (9160): v4l: remove vidioc_enum_fmt_vbi_cap

Remove the vidioc_enum_fmt_vbi_cap ops: it was scheduled for removal in
2.6.28 since the v4l2 specification says that V4L2_BUF_TYPE_VBI_CAPTURE should
not support VIDIOC_ENUM_FMT. It's also pretty pointless.

Subject: V4L/DVB (9162): ivtv: fix raw/sliced VBI mixup

The service_set field was used in saa7115 and cx25840 to determine
whether raw or sliced VBI was desired. This is incorrect since it is
perfectly valid to select sliced VBI with a service_set of 0.

Instead these drivers should checked on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.

Updated ivtv accordingly.

Subject: V4L/DVB (9166): ivtv - Fix potential race condition in yuv handler

Modified yuv register update handling to remove a potential race condition
which could occur with the first video frame.

Also removed a forced yuv position update, since changing the source video
dimensions or interlace settings doesn't affect the frame already being
displayed.

Subject: V4L/DVB (9168): Add support for MSI TV@nywhere Plus remote

The IR controller has a couple quirks. It won't respond until some other
device on the bus is probed. To work around that, probe 0x50 first.
Then, since it won't respond to a zero-byte read, probe with a one-byte
read.

Subject: [SCSI] Add helper code so transport classes/driver can control
 queueing (v3)

SCSI-ml manages the queueing limits for the device and host, but
does not do so at the target level. However something something similar
can come in userful when a driver is transitioning a transport object to
the the blocked state, becuase at that time we do not want to queue
io and we do not want the queuecommand to be called again.

The patch adds code similar to the exisiting SCSI_ML_*BUSY handlers.
You can now return SCSI_MLQUEUE_TARGET_BUSY when we hit
a transport level queueing issue like the hw cannot allocate some
resource at the iscsi session/connection level, or the target has temporarily
closed or shrunk the queueing window, or if we are transitioning
to the blocked state.

bnx2i, when they rework their firmware according to netdev
developers requests, will also need to be able to limit queueing at this
level. bnx2i will hook into libiscsi, but will allocate a scsi host per
netdevice/hba, so unlike pure software iscsi/iser which is allocating
a host per session, it cannot set the scsi_host->can_queue and return
SCSI_MLQUEUE_HOST_BUSY to reflect queueing limits on the transport.

The iscsi class/driver can also set a scsi_target->can_queue value which
reflects the max commands the driver/class can support. For iscsi this
reflects the number of commands we can support for each session due to
session/connection hw limits, driver limits, and to also reflect the
session/targets's queueing window.

Changes:
v1 - initial patch.
v2 - Fix scsi_run_queue handling of multiple blocked targets.
Previously we would break from the main loop if a device was added back on
the starved list. We now run over the list and check if any target is
blocked.
v3 - Rediff for scsi-misc.

Subject: [SCSI] qla4xxx: return SCSI_MLQUEUE_TARGET_BUSY when driver has
 detected session error

When qla4xxx begins recovery and the iscsi class is firing up to handle
it, we need to retrn SCSI_MLQUEUE_TARGET_BUSY from the driver instead
of host busy, because the session recovery only affects the one target.

Subject: [SCSI] qla2xxx: return SCSI_MLQUEUE_TARGET_BUSY when driver has
 detected rport error or race

If the fcport is not online then we do not want to block IO to all ports on
the host. We just want to stop IO on port not online, so we should be using
the SCSI_MLQUEUE_TARGET_BUSY return value.

For the case where we race with the rport memset initialization
we do not want the queuecommand to be called again so we can just use
SCSI_MLQUEUE_TARGET_BUSY for this.

Subject: [SCSI] fc class: unblock target after calling terminate callback
 (take 2)

When we block a rport and the driver implements the terminate
callback we will fail IO that was running quickly. However
IO that was in the scsi_device/block queue sits there until
the dev_loss_tmo fires, and this can make it look like IO is
lost because new IO will get executed but that IO stuck in
the blocked queue sits there for some time longer.

With this patch when the fast io fail tmo fires, we will
fail the blocked IO and any new IO. This patch also allows
all drivers to partially support the fast io fail tmo. If the
terminate io callback is not implemented, we will still fail blocked
IO and any new IO, so multipath can handle that.

This patch also allows the fc and iscsi classes to implement the
same behavior. The timers are just unfornately named differently.

This patch also fixes the problem where drivers were unblocking
the target in their terminate callback, which was needed for
rport removal, but for fast io fail timeout it would cause
IO to bounce arround the scsi/block layer and the LLD queuecommand.
And it for drivers that could have IO stuck but did not have
a terminate callback the unblock calls in the class will fix
them.

v2.
- fix up bit setting style to meet JamesS's pref.
- Broke out new host byte error changes to make it easier to read.
- added JamesS's ack from list.
v1
- initial patch

Subject: [SCSI] ibmvfc, qla2xxx, lpfc: remove scsi_target_unblock calls in
 terminate callbacks

The fc class now calls scsi_target_unblock after calling the
terminate callback, so this patch removes the calls from the
drivers.

Subject: [SCSI] scsi: add transport host byte errors (v3)

Currently, if there is a transport problem the iscsi drivers will return
outstanding commands (commands being exeucted by the driver/fw/hw) with
DID_BUS_BUSY and block the session so no new commands can be queued.
Commands that are caught between the failure handling and blocking are
failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values.
When the recovery_timeout fires, the iscsi drivers then fail IO with
DID_NO_CONNECT.

For fcp, some drivers will fail some outstanding IO (disk but possibly not
tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry
and hits the scsi_error.c failfast check, block the rport, and commands
caught in the race are failed with DID_IMM_RETRY. Other drivers, may
hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk
to be called.

The following patches attempt to unify what upper layers will see drivers
like multipath can make a good guess. This relies on drivers being
hooked into their transport class.

This first patch just defines two new host byte errors so drivers can
return the same value for when a rport/session is blocked and for
when the fast_io_fail_tmo fires.

The idea is that if the LLD/class detects a problem and is going to block
a rport/session, then if the LLD wants or must return the command to scsi-ml,
then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue
the IO into the same scsi queue it came from, until the fast io fail timer
fires and the class decides what to do.

When using multipath and the fast_io_fail_tmo fires then the class
can fail commands with DID_TRANSPORT_FAILFAST or drivers can use
DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or
the equivlent in iscsi if we ever implement more advanced recovery methods.
A LLD, like lpfc, could continue to return DID_ERROR and then it will hit
the normal failfast path, so drivers do not have fully be ported to
work better. The point of the patches is that upper layers will
not see a failure that could be recovered from while the rport/session is
blocked until fast_io_fail_tmo/recovery_timeout fires.

V3
Remove some comments.
V2
Fixed patch/diff errors and renamed DID_TRANSPORT_BLOCKED to
DID_TRANSPORT_DISRUPTED.
V1
initial patch.

Subject: [SCSI] qla2xxx: use new host byte transport errors.

This has qla2xxx use the new transport error values instead of
DID_BUS_BUSY. I am not sure if all the errors
in qla_isr.c I changed are transport related. We end up blocking/deleting
the rport for all of them so it is better to use the new transport error since
the fc classs will decide when to fail the IO.

With this patch if I pull a cable then IO that had reached
the driver, will be failed with DID_TRANSPORT_DISRUPTED (not including
tape). The fc class will then fail the IO when the fast io fail tmo
has fired, and the driver will flush any other commands running.

Subject: [SCSI] block: separate failfast into multiple bits.

Multipath is best at handling transport errors. If it gets a device
error then there is not much the multipath layer can do. It will just
access the same device but from a different path.

This patch breaks up failfast into device, transport and driver errors.
The multipath layers (md and dm mutlipath) only ask the lower levels to
fast fail transport errors. The user of failfast, read ahead, will ask
to fast fail on all errors.

Note that blk_noretry_request will return true if any failfast bit
is set. This allows drivers that do not support the multipath failfast
bits to continue to fail on any failfast error like before. Drivers
like scsi that are able to fail fast specific errors can check
for the specific fail fast type. In the next patch I will convert
scsi.

Subject: [SCSI] modify scsi to handle new fail fast flags.

This checks the errors the scsi-ml determined were retryable
and returns if we should fast fail it based on the request
fail fast flags.

Without the patch, drivers like lpfc, qla2xxx and fcoe would return
DID_ERROR for what it determines is a temporary communication problem.
There is no loss of connectivity at that time and the driver thinks
that it would be fast to retry at the driver level. SCSI-ml will however
sees fast fail on the request and DID_ERROR and will fast fail the io.
This will then cause dm-multipath to fail the path and possibley switch
target controllers when we should be retrying at the scsi layer.

We also were fast failing device errors to dm multiapth when
unless the scsi_dh modules think otherwis we want to retry at
the scsi layer because multipath can only retry the IO like scsi
should have done. multipath is a little dumber though because it
does not what the error was for and assumes that it should fail
the paths.

From: James Smart <James.Smart@Emulex.Com>
Date: Sun, 24 Aug 2008 21:50:00 -0400
Subject: [SCSI] lpfc 8.2.8 : Miscellaneous Bug Fixes

Miscellaneous Fixes:
- Fix the wrong variable name used for checking node active usage status
- Fix numerous duplicate log message numbers
- Fix change KERN_WARNING messages to KERN_INFO.
- Stop sending erroneous LOGO to fabric after vport is already terminated
- Fix HBQ allocates that were kalloc'ing w/ GFP_KERNEL while holding a lock.
- Fix gcc 4.3.2 compiler warnings and a sparse warning
- Fix bugs in handling unsolicited ct event queue
- Reorder some of the initial link up checks, to remove odd VPI states.
- Correct poor VPI handling
- Add debug messages
- Expand Update_CFG mailbox definition
- Fix handling of VPD data offsets
- Reorder loopback flags
- convert to use offsetof()

Subject: [SCSI] scsi_dh_alua: remove REQ_NOMERGE

We do not need to set REQ_NOMERGE because when the module calls
blk_execute_rq -> blk_execute_rq_nowait, blk_execute_rq_nowait sets
it for us. This brings all the modules in sync for those bits.

From ea2151b4e142fa2de0319d9dd80413a997bf435a Mon Sep 17 00:00:00 2001
From: James Smart <James.Smart@Emulex.Com>
Date: Sun, 7 Sep 2008 11:52:10 -0400
Subject: [SCSI] lpfc 8.2.8 v2 : Add statistical reporting control and
 additional fc vendor events

Added support for new sysfs attributes: lpfc_stat_data_ctrl and
lpfc_max_scsicmpl_time. The attributes control statistical reporting
of io load.

Added support for new fc vendor events for error reporting.

Subject: [SCSI] scsi_error: fix target reset handling

There's a target reset bug.

This loop:

	for (id = 0; id <= shost->max_id; id++) {

Never terminates if shost->max_id is set to ~0, like aic94xx does.

It's also pretty inefficient since you mostly have compact target
numbers, but the max_id can be very high.  The best way would be to
sort the recovery list by target id and skip them if they're equal,
but even a worst case O(N^2) traversal is probably OK here, so fix it
by finding the next highest target number (assuming n+1) and
terminating when there isn't one.

Subject: [SCSI] sd: Issue correct protection operation

Use the same logic to prepare RD/WRPROTECT and the protection
operation.  Fixes a corner case where we could issue an unprotected
CDB and yet tell the HBA to do DIF to the drive.

Subject: [SCSI] sd: Always print actual protection_type

Now that we no longer use protection_type as trigger for preparing
protected CDBs we can remove the places that set it to zero.  This
allows userland to see which protection type the device is formatted
with regardless of whether the HBA supports DIF or not.

Subject: [SCSI] libiscsi: fix data corruption when target has to resend
 data-in packets

iscsi_tcp was updating the exp_statsn (exp_statsn acknowledges
status and tells the target it is ok to let the resources for
a iscsi pdu to be reused) before it got all the data for pdu read
into OS buffers. Data corruption was occuring if something happens
to a packet and the network layer requests a retransmit, and the
initiator has told the target about the udpated exp_statsn ack,
then the target may be sending data from a buffer it has reused
for a new iscsi pdu. This fixes the problem by having the LLD
(iscsi_tcp in this case) just handle the transferring of data, and
has libiscsi handle the processing of status (libiscsi completion
processing is done after LLD data transfers are complete).

Subject: [SCSI] libiscsi: Support drivers initiating session removal

If the driver knows when hardware is removed like with cxgb3i,
bnx2i, qla4xxx and iser then we will want to remove the sessions/devices
that are bound to that device before removing the host.

cxgb3i and in the future bnx2i will remove the host and that will
remove all the sessions on the hba. iser can call iscsi_kill_session
when it gets an event that indicates that a hca is removed.
And when qla4xxx is hooked in to the lib (it is only hooked into
the class right now) it can call iscsi remove host like the
partial offload card drivers.

Subject: [SCSI] iscsi class: fix endpoint id handling

Some endpoint code was using unsigned int and some
was using uint64_t. This converts it all to uint64_t.

Subject: [SCSI] libiscsi: rename host reset to target reset

I had this in my patchset to add target reset support, but
it got dropped due to patching conflicts. This initial patch
just renames the function and users. We are actually just
dropping the session, and so this does not have anything to do
with the host exactly. It does for software iscsi because
we allocate a host per session, but for cxgb3i this makes no
sense.

Subject: [SCSI] iscsi_tcp: return a descriptive error value during connection
 errors

The segment->done functions return a iscsi error value which gives
a lot more info than conn failed, so this patch has us return
that value. I also add a new one for xmit failures.

Some wires got crossed on some patches and I messed up in the code
below when rebuilding a patch. We want to be checking if flag
equaled the value indicating if we killing the session due to
final logout or if we just trying to relogin.

Subject: libiscsi: fix locking in iscsi_eh_device_reset

We must be using the bh spin locking functions in
iscsi_eh_device_reset becuase the session lock interacts with
a thread and softirq.

This patch also fixes up a bogus comment and check in fail_command,
because no one drops the lock (bnx2i did but it is not going
upstream yet and there were other refcount changes for that).

Subject: V4L/DVB (9170): cx24116: Sanity checking to data input via S2API to
 the cx24116 demod.

Add some sanity checking to data input via S2API to the cx24116 demod.
This patch is valid for both s2-mfe and s2.

It was found when testing KAFFEINE with S2API support that invalid
modulation modes amongst other parameters were being delivered to
the demod. In order to debug this sanity checking has been added.

An example session would involve kaffeine setting QAM_AUTO when
querying DVB-T, then later when trying to tune to DVB-S this
cached value would be presented in error.

Subject: V4L/DVB (9172): S2API: Bugfix related to DVB-S / DVB-S2 tuning for
 the legacy API.

Fixes switching from S2API to legacy where legacy params given to S2API
aware demods are cached ones and not those implied in the legacy API.

It was found (on an S2API aware demod at least) that after using
an S2API aware application and then switching to a legacy application
that prior S2API params were in effect were legacy has only
implied values. This fixes this.

From: Steven Toth <stoth@linuxtv.org>
Date: Mon, 6 Oct 2008 21:06:48 -0300
Subject: V4L/DVB (9177): S2API: Change _8PSK / _16APSK to PSK_8 and APSK_16

... and cleanup any drivers using them.
I've also removed NBC_QPSK and modified the cx24116 driver to check
the delivery_type also, removing some excess namespace baggage.

Subject: Automatic MODULE_ALIAS() for DMI match tables.

This makes modpost handle MODULE_DEVICE_TABLE(dmi, xxxx).

I had to change the string pointers in the match table to char arrays,
and picked a size of 79 bytes almost at random -- do we need to make it
bigger than that? I was a bit concerned about the 'bloat' this
introduces into the match tables, but they should all be __initdata so
it shouldn't matter too much.

(Actually, modpost does go through the relocations and look at most of
them; it wouldn't be impossible to make it handle string pointers -- but
doesn't seem to be worth the effort, since they're __initdata).

Subject: Fix autoloading of MacBook Pro backlight driver.

Use new MODULE_DEVICE_TABLE(dmi, ...) facility. There's no need for
every driver to screw it up for themselves, when the alias can be

Subject: x86/mm: do not trigger a kernel warning if user-space disables
 interrupts and generates a page fault

Arjan reported a spike in the following bug pattern in v2.6.27:

   http://www.kerneloops.org/searchweek.php?search=lock_page

which happens because hwclock started triggering warnings due to
a (correct) might_sleep() check in the MM code.

The warning occurs because hwclock uses this dubious sequence of
code to run "atomic" code:

  static unsigned long
  atomic(const char *name, unsigned long (*op)(unsigned long),
         unsigned long arg)
  {
    unsigned long v;
    __asm__ volatile ("cli");
    v = (*op)(arg);
    __asm__ volatile ("sti");
    return v;
  }

Then it pagefaults in that "atomic" section, triggering the warning.

There is no way the kernel could provide "atomicity" in this path,
a page fault is a cannot-continue machine event so the kernel has to
wait for the page to be filled in.

Even if it was just a minor fault we'd have to take locks and might have
to spend quite a bit of time with interrupts disabled - not nice to irq
latencies in general.

So instead just enable interrupts in the pagefault path unconditionally
if we come from user-space, and handle the fault.

Also, while touching this code, unify some trivial parts of the x86
VM paths at the same time.

Subject: powerpc: GE Fanuc's FPGA based PIC controller on the SBC610

Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D).

A number of MPC8641D based route interrupts for on-board interrupts through
a FPGA based interrupt controller, which is chained with the
MPC8641D's mpic. This patch provides a basic driver to allow basic routing
of interrupts to the mpic.

Subject: powerpc: make Freescale QE support a selectable Kconfig option

Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable
option, thereby allowing users to compile kernels without any QE support.

The drawback is that QE support is now disabled by default on platforms that
have a QE, and so a defconfig is needed to enable QE and QE devices (like
UCC GETH).  Fortunately, all the current relevant defconfigs do that already.

Subject: powerpc/QE: move QE_GPIO Kconfig symbol into the platforms/Kconfig

Specifying user-selectable option in the qe_lib/Kconfig was a bad idea
because the qe_lib/Kconfig is included into the top level Kconfig, and
thus the QE_GPIO option appears at the top level menu.

This patch effectively moves the QE_GPIO option under the platform menu
instead.

Subject: powerpc/83xx: don't probe broken PCI on mpc837x_mds boards

In the standalone setup the board's CPLD disables the PCI internal
arbiter, thus any access to the PCI bus will hang the board.

The common way to disable particular devices in the device tree is to
put the "status" property with any value other than "ok" or "okay"
into the device node we want to disable.

So, when there is no PCI arbiter on the bus the u-boot adds status =
"broken (no arbiter)" property into the PCI controller's node, and so
marks the PCI controller as unavailable.

Subject: powerpc: 83xx: pci: Remove need for get_immrbase from
 mpc83xx_add_bridge.

Modify mpc83xx_add_bridge to get config space register base address from
the device tree instead of immr + hardcoded offset.

83xx pci nodes have this change:
    register properties now contain two address length tuples:
	First is the pci bridge register base, this has always been there.
	Second is the config base, this is new.

This is documented in dts-bindings/fsl/83xx-512x-pci.txt

The changes accomplish these things:
    mpc83xx_add_bridge no longer needs to call get_immrbase
    it uses hard coded addresses if the second register value is missing

Subject: powerpc: remove non-dependent load fsl_booke PTE_64BIT

b38fd42ff46a4a31dced8533e8a6e549693500b6 added false dependencys
to order the load of upper and lower halfs of the pte, but only
adjusted whitespace instead of deleting the old load in the iside
handler, letting the hardware see the non-dependent load.

This patch removes the extra load.

Subject: powerpc: remove support for bootmem-allocated memory for the DIU
 driver

Early versions of the Freescale DIU framebuffer driver depended on a bootmem
allocation of memory for the video buffer.  The need for this feature was
removed in commit 6b51d51a, so now we can remove the platform-specific code
that allocated that memory.

Subject: OF: add fsl,mcu-mpc8349emitx to the exception list

of/base.c matches on the first (most specific) entries, which isn't
quite practical but it was discussed[1] that this won't change.

The bindings specifies verbose information for the devices, but
it doesn't fit in the I2C ID's 20 characters limit. The limit won't
change[2], and the bindings won't change either as they're correct.

So we have to put an exception for the MPC8349E-mITX-compatible
MCUs.

Subject: powerpc: document the "fsl,ssi-dma-channel" compatible property

The "fsl,ssi-dma-channel" compatible property is used to specify a DMA channel
on the Freescale Elo DMA controller that should be used exclusively by the
Freescale SSI audio controller.  When a property is marked as such, the Elo
DMA driver will ignore it, and so it will be available for the sound drivers.

Subject: powerpc: reserve two DMA channels for audio in MPC8610 HPCD device
 tree

The Freescale Elo DMA driver binds to all DMA channels in the device tree that
are compatible with "fsl,eloplus-dma-channel".  This conflicts with the sound
drivers for the MPC8610 HPCD.  On this board, the SSI uses two DMA channels and
therefore those channels are not available for general purpose use.  We
change the compatible properties for these channels "fsl,ssi-dma-channel".
This works because the sound drivers don't actually check the compatible
property when it grabs channels.

On MPC8349E-mITX, MPC8315E-RDB and MPC837x-RDB boards there is a
Freescale MC9S08QG8 (MCU) chip with the custom firmware
pre-programmed. The chip is used to power-off the board by the
software, and to control some GPIO pins.

Subject: x86/mm: unify init task OOM handling

Linus noticed that the "again:" versus "survive:" OOM logic for
the init task was arbitrarily different.

The 64-bit codepath is the better one, because it correctly re-lookups
the vma after having dropped the ->mmap_sem.

Subject: powerpc: fix fsl_upm nand driver modular build

The fsl_upm nand driver fails to build because fsl_lbc_lock isn't
exported, the lock is needed by the inlined fsl_upm_run_pattern()
function:

ERROR: "fsl_lbc_lock" [drivers/mtd/nand/fsl_upm.ko] undefined!

Dave Jones purposed to export the lock, but it is better to just uninline
the fsl_upm_run_pattern().

When uninlined we also no longer need the exported fsl_lbc_regs, and
both fsl_lbc_lock and fsl_lbc_regs could be marked static.

While at it, also add some missing includes that we should have included
explicitly.

Subject: vfs: Use const for kernel parser table

This is a much better version of a previous patch to make the parser
tables constant. Rather than changing the typedef, we put the "const" in
all the various places where its required, allowing the __initconst
exception for nfsroot which was the cause of the previous trouble.

This was posted for review some time ago and I believe its been in -mm
since then.

From 8f808417fe211648c0816e28947cdc74eb1e1032 Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@kernel.org>

Subject: CRIS: proper defconfig setup

This patch moves the cris defconfigs to arch/cris/configs/ where they
belong.

As a side effect they can now be used directly through e.g.
  make ARCH=cris artpec_3_defconfig

The default defconfig is set through KBUILD_DEFCONFIG.

Subject: sgiioc4: sgiioc4_read_status drive busy check fix

Fix the drive non-busy criterion used by sgiioc4_read_status(): neither of the
bits it expects to be set guarantees that the drive is not busy (and might be
interrupting), only the BSY bit itself being zero gurantees that.
While at it, use ATA_BUSY instead of hardcoded value everywhere...

Subject: sgiioc4: fix messages

Fix several issues with the log messages printed by ide_dma_sgiioc4() and
sgiioc4_ide_setup_pci_device():

- IOC4 registers are memory-mapped but the "BM-DMA at" format corresponds to
  I/O  mapped registers;

- "%p" format specifiers and type casts used to print non-pointer values;

- using KERN_INFO log level for the error message;

- 'hwif->name' printed as drive's name.

While at it, also:

- return more fitting -EBUSY if request_mem_region() fails;

- make the error message style consistent;

- fix indentation, put the printk() facility and message on the same line;

- use comparisions with NULL instead of ! operator..

Subject: ide: drop dsc_handle argument from ide_pc_intr()

* Add 'int dsc' argument to ->pc_callback method.

* Call ide_tape_handle_dsc() internally in ide_tape_callback()
  if dsc argument is set and update ide_pc_intr() accordingly.

There should be no functional changes caused by this patch.

From 2b9efba48283f34083df6bc53f6752fba4e4d409 Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Mon, 13 Oct 2008 21:39:31 +0200
Subject: ide: add pointer to the current packet command to ide_drive_t

* Add pointer to the current packet command (struct ide_atapi_pc *pc)
  to ide_drive_t and use it instead of the pointer in struct ide_*_obj.

* Use drive->pc in ide_{issue,transfer}_pc() and ide_pc_intr()
  instead of 'pc' argument.

There should be no functional changes caused by this patch.

Subject: ide: drop 'timeout' and 'expiry' arguments from ide_pc_intr()

* Move idescsi_expiry() to ide-atapi.c.

* Move get_timeout() to <linux/ide.h>.

* Drop 'timeout' and 'expiry' arguments from ide_pc_intr().

While at it:

* idescsi_expiry() -> ide_scsi_expiry()

* get_timeout() -> ide_scsi_get_timeout()

There should be no functional changes caused by this patch.

Subject: ide: add request_sense_{pc,rq} to ide_drive_t

Add 'struct ide_atapi_pc request_sense_pc' and 'request request_sense_rq' to
ide_drive_t and use them instead of fields in struct ide_{floppy,tape}_obj.

There should be no functional changes caused by this patch.

Subject: ide: add ->pc_{update,io}_buffers methods

Add ->pc_{update,io}_buffers methods to ide_drive_t and use
them instead of {update,io}_buffers ide_pc_intr() arguments.

There should be no functional changes caused by this patch.

From baf08f0be6d986521bb2fbdc7af51fc4847da734 Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Mon, 13 Oct 2008 21:39:32 +0200
Subject: ide: make ide_transfer_pc() static

* Move ->ticks field from struct ide_floppy_obj to ide_drive_t.

* Move idefloppy_transfer_pc() to ide-atapi.c and make
  ide_transfer_pc() use it.

* Always use ide_transfer_pc as a handler in ide_issue_pc().

* Remove no longer used idefloppy_start_pc_transfer(),
  ide*_transfer_pc() and 'handler' argument from ide_issue_pc().

* Make ide_transfer_pc() static.

While at it:

* idefloppy_transfer_pc() -> ide_delayed_transfer_pc()

* IDEFLOPPY_TICKS_DELAY -> IDEFLOPPY_PC_DELAY

* ->ticks -> ->pc_delay

There should be no functional changes caused by this patch.

Subject: ide: remove CONFIG_BLK_DEV_IDE config option (take 2)

Because hd.c was moved to drivers/block/ this config option
is superfluous now and may be removed.

v2:
Fix drivers/ide/Makefile (noticed by Adrian Bunk).

Subject: ide: unify conversion macros

Introduce to_ide_drv() and ide_drv_g() macros and replace the respective
definitions of similar ones in each driver.

There should be no functionality change resulting from this patch.

Add __ide_debug_log() debugging macro which is controlled by drive->debug_mask.
The macro has to have the macro DRV_NAME defined in each driver before use.
Also, add different debugging levels depending on the functionality debugged.

Also:

- leave in the possibility for optimizing away all debugging macros
- add a PFX macro and prepend all printk calls with it for consistency
- change idefloppy_create_rw_cmd's 1st arg from idefloppy_floppy_t * to
ide_drive_t *.
- add a missing printk-level in idefloppy_init
- fix minor checkpatch warnings

Add 'unsigned long dev_flags' to ide_drive_t and convert bitfields
to IDE_DFLAG_* flags.

While at it:
- IDE_DFLAG_ADDRESSING -> IDE_DFLAG_LBA48
- fixup some comments
- remove needless g->flags zeroing from ide*_probe()

There should be no functional changes caused by this patch.

Subject: ide: DMA_PIO_RETRY -> IDE_DFLAG_DMA_PIO_RETRY

Add IDE_DFLAG_DMA_PIO_RETRY and use it instead of
ide_drive_t.state + DMA_PIO_RETRY.

There should be no functional changes cause by this patch.

Subject: ide: fix HDIO_DRIVE_TASK[FILE] ioctls for CHS commands on LBA devices

Add IDE_DFLAG_LBA device flag and use it instead of ->select.b.lba.

Since ->tf_load uses ->select.all for ATA Device/Head register this
fixes HDIO_DRIVE_TASK[FILE] ioctls for CHS commands on LBA devices.

Subject: ide: use 'drive->dn & 1' instead of drive->select.b.unit

* Call ide_port_init_devices() in ide_host_register()
  also if 'struct ide_port_info *d' is not available.

* Init drive->dn in ide_port_init_devices() instead of
  ide_probe_port() so it is valid also in ->init_dev.

* Pass device number to ide_dev_apply_params().

* Use 'drive->dn & 1' instead of drive->select.b.unit.

There should be no functional changes caused by this patch.

Subject: ide: remove [ata_]select_t

* Use 'drive->dn & 1' in ide_init_disk().

* remove [ata_]select_t.

While at it:

* Use ATA_DEVICE_OBS define in ide_port_init_devices_data().

Subject: ide: factor out reset error reporting from reset_pollfunc()

Factor out reset error reporting from reset_pollfunc()
to ide_reset_report_error() helper.

While at it:
- fix KERN_* printk() levels
- remove 'switch ()'

Date: Mon, 13 Oct 2008 21:39:42 +0200
Subject: ide: ->ide_dma_clear_irq() -> ->clear_irq()

* Rename ->ide_dma_clear_irq method to ->clear_irq
  and move it from ide_hwif_t to struct ide_port_ops.

* Move ->waiting_for_dma check inside ->clear_irq method.

* Move ->dma_base check inside ->clear_irq method.

piix.c:
* Add ich_port_ops and remove init_hwif_ich() wrapper.

There should be no functional changes caused by this patch.

There is now a generic solution [ide_generic_check_pci_legacy_iobases()]
so MIPS-specific ide_probe_legacy() is no longer necessary.

Subject: ide: set IDE_AFLAG_DRQ_INTERRUPT in do_identify()

Set IDE_AFLAG_DRQ_INTERRUPT in do_identify() instead of ATAPI
device drivers *_setup() methods.

While at it:
- use ata_id_cdb_intr()

There should be no functional changes caused by this patch.

Date: Mon, 13 Oct 2008 21:39:45 +0200
Subject: ide: Two fixes regarding memory allocation

In function ide_devset_execute() we should use __GFP_WAIT rather than
GFP_KERNEL. Also, the allocation cannot possibly fail at that point.
More importantly, there is a potential memory leak in the device probing
code. The infrastructure seems rather complex and I hope I haven't messed
anything up by trying to fix this.

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Subject: ide: switch to DMA-mapping API part #2

Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf
("ide: switch to DMA-mapping API"):

* pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent()
  in ide_{allocate,release}_dma_engine().

* Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t
  (+ set default values in ide_allocate_dma_engine()).

* Make ide_{allocate,release}_dma_engine() available also
  for CONFIG_BLK_DEV_IDEDMA_SFF=n.  Then convert au1xxx-ide.c,
  scc_pata.c and sgiioc4.c to use them.

* Add missing ->init_dma method to scc_pata.

This patch also fixes:
- ->dmatable_cpu leak for au1xxx-ide
- too early realease of ->dmatable_cpu for scc_pata
- wrong amount of ->dmatable_cpu memory being freed for sgiioc4

While at it:
- remove superfluous ->dma_base check from ide_unregister()
- return -ENOMEM on error in ide_release_dma_engine()
- beautify error message in ide_release_dma_engine()

From fc8323f793852ca1fcb58d96512fd71d39af2e9b Mon Sep 17 00:00:00 2001
From: Borislav Petkov <petkovbb@googlemail.com>
Date: Mon, 13 Oct 2008 21:39:48 +0200
Subject: ide-cd: convert driver to new ide debugging macro (v3)

Also,

- leave in the possibility for optimizing away all debugging macros
- add a PFX macro and prepend all printk calls with it for consistency
- add debug macro calls in important driver paths
- remove #if 0-ed code
- mv restore_request -> ide_cd_restore_request
- add a driver registration printk

v2:
failed_command can be NULL so check it before accessing it

v3:
fix another NULL ptr in debug statement

There should be no functionality change resulting from this patch.

Subject: ide: Implement disk shock protection support (v4)

On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD
FEATURE as specified in ATA-7 is issued to the device and processing of
the request queue is stopped thereafter until the specified timeout
expires or user space asks to resume normal operation. This is supposed
to prevent the heads of a hard drive from accidentally crashing onto the
platter when a heavy shock is anticipated (like a falling laptop expected
to hit the floor). Port resets are deferred whenever a device on that
port is in the parked state.

v3:

v4:
Fix a memory leak due to a missing blk_put_request() in
issue_park_cmd(). Additionally, we should plug the queue when enqueueing
the unpark request because there is no guarantee that the park timeout
has not expired by then. Even though the chance for that to happen is
very slim, the request might end up hanging in the queue until the next
I/O operation is queued up. While at it, clean up the code a little:
- make issue_park_cmd() a function of type void since nobody cares for
  the return value anyway;
- use blk_start_queueing() instead of __blk_run_queue() since we don't
  have to worry about recursion;
- remove a superfluous pointer deference in task_no_data_intr().

Subject: ata: Add documentation for hard disk shock protection interface (v3)

Put some information (and pointers to more) into the kernel's doc tree,
describing briefly the interface to the kernel's disk head unloading
facility. Information about how to set up a complete shock protection
system under GNU/Linux can be found on the web and is referenced
accordingly.

v3:
Here is some final polish including various spelling corrections
pointed out by Grant Grundler and Peter Moulder. Also, I have added some
information about the timing constraints related to disk head parking.
The patch looks more impressive than it really is and I think it would
be alright just to incorporate it into the original patch so as not to
clutter up the git log.

+Hard disk shock protection

+1. Intro
+--------
+
+ATA/ATAPI-7 specifies the IDLE IMMEDIATE command with unload feature.
+Issuing this command should cause the drive to switch to idle mode and
+unload disk heads. This feature is being used in modern laptops in
+conjunction with accelerometers and appropriate software to implement
+a shock protection facility. The idea is to stop all I/O operations on
+the internal hard drive and park its heads on the ramp when critical
+situations are anticipated. The desire to have such a feature
+available on GNU/Linux systems has been the original motivation to
+implement a generic disk head parking interface in the Linux kernel.
+Please note, however, that other components have to be set up on your
+system in order to get disk shock protection working (see
+section 3. References below for pointers to more information about
+that).
+
+
+2. The interface
+----------------
+
+For each ATA device, the kernel exports the file
+block/*/device/unload_heads in sysfs (here assumed to be mounted under
+/sys). Access to /sys/block/*/device/unload_heads is denied with
+-EOPNOTSUPP if the device does not support the unload feature.
+Otherwise, writing an integer value to this file will take the heads
+of the respective drive off the platter and block all I/O operations
+for the specified number of milliseconds. When the timeout expires and
+no further disk head park request has been issued in the meantime,
+normal operation will be resumed. The maximal value accepted for a
+timeout is 30000 milliseconds. Exceeding this limit will return
+-EOVERFLOW, but heads will be parked anyway and the timeout will be
+set to 30 seconds. However, you can always change a timeout to any
+value between 0 and 30000 by issuing a subsequent head park request
+before the timeout of the previous one has expired. In particular, the
+total timeout can exceed 30 seconds and, more importantly, you can
+cancel a previously set timeout and resume normal operation
+immediately by specifying a timeout of 0. Values below -2 are rejected
+with -EINVAL (see below for the special meaning of -1 and -2). If the
+timeout specified for a recent head park request has not yet expired,
+reading from /sys/block/*/device/unload_heads will report the number
+of milliseconds remaining until normal operation will be resumed;
+otherwise, reading the unload_heads attribute will return 0.
+
+For example, do the following in order to park the heads of drive
+/dev/sda and stop all I/O operations for five seconds:
+
+# echo 5000 > /sys/block/sda/device/unload_heads
+
+A simple
+
+# cat /sys/block/sda/device/unload_heads
+
+will show you how many milliseconds are left before normal operation
+will be resumed.
+
+A word of caution: The fact that the interface operates on a basis of
+milliseconds may raise expectations that cannot be satisfied in
+reality. In fact, the ATA specs clearly state that the time for an
+unload operation to complete is vendor specific. The hint in ATA-7
+that this will typically be within 500 milliseconds apparently has
+been dropped in ATA-8.
+
+There is a technical detail of this implementation that may cause some
+confusion and should be discussed here. When a head park request has
+been issued to a device successfully, all I/O operations on the
+controller port this device is attached to will be deferred. That is
+to say, any other device that may be connected to the same port will
+be affected too. The only exception is that a subsequent head unload
+request to that other device will be executed immediately. Further
+operations on that port will be deferred until the timeout specified
+for either device on the port has expired. As far as PATA (old style
+IDE) configurations are concerned, there can only be two devices
+attached to any single port. In SATA world we have port multipliers
+which means that a user-issued head parking request to one device may
+actually result in stopping I/O to a whole bunch of devices. However,
+since this feature is supposed to be used on laptops and does not seem
+to be very useful in any other environment, there will be mostly one
+device per port. Even if the CD/DVD writer happens to be connected to
+the same port as the hard drive, it generally *should* recover just
+fine from the occasional buffer under-run incurred by a head park
+request to the HD. Actually, when you are using an ide driver rather
+than its libata counterpart (i.e. your disk is called /dev/hda
+instead of /dev/sda), then parking the heads of one drive (drive X)
+will generally not affect the mode of operation of another drive
+(drive Y) on the same port as described above. It is only when a port
+reset is required to recover from an exception on drive Y that further
+I/O operations on that drive (and the reset itself) will be delayed
+until drive X is no longer in the parked state.
+
+Finally, there are some hard drives that only comply with an earlier
+version of the ATA standard than ATA-7, but do support the unload
+feature nonetheless. Unfortunately, there is no safe way Linux can
+detect these devices, so you won't be able to write to the
+unload_heads attribute. If you know that your device really does
+support the unload feature (for instance, because the vendor of your
+laptop or the hard drive itself told you so), then you can tell the
+kernel to enable the usage of this feature for that drive by writing
+the special value -1 to the unload_heads attribute:
+
+# echo -1 > /sys/block/sda/device/unload_heads
+
+will enable the feature for /dev/sda, and giving -2 instead of -1 will
+disable it again.
+
+
+3. References
+-------------
+
+There are several laptops from different vendors featuring shock
+protection capabilities. As manufacturers have refused to support open
+source development of the required software components so far, Linux
+support for shock protection varies considerably between different
+hardware implementations. Ideally, this section should contain a list
+of pointers at different projects aiming at an implementation of shock
+protection on different systems. Unfortunately, I only know of a
+single project which, although still considered experimental, is fit
+for use. Please feel free to add projects that have been the victims
+of my ignorance.

+particular by Tejun Heo and Bartlomiej Zolnierkiewicz.

Subject: regulator: core - Rework machine API to remove string based
 functions.

This improves the machine level API in order to configure
regulator constraints and consumers as platform data and removes the
old string based API that required several calls to set up each regulator.

The intention is to create a struct regulator_init_data, populate
it's fields with constraints, consumers devices, etc and then register
the regulator device from board.c in the standard Linux way.

e.g. regulator LDO2 (supplying codec and sim) platform data.

/* regulator LDO2 consumer devices */
static struct regulator_consumer_supply ldo2_consumers[] = {
{
	.dev	= &platform_audio_device.dev,
	.supply	= "codec_avdd",
},
{
	.dev	= &platform_sim_device.dev,
	.supply	= "sim_vcc",
}
};

/* regulator LDO2 constraints  */
static struct regulator_init_data ldo2_data = {
	.constraints = {
		.min_uV = 3300000,
		.max_uV = 3300000,
		.valid_modes_mask = REGULATOR_MODE_NORMAL,
		.apply_uV = 1,
	},
	.num_consumer_supplies = ARRAY_SIZE(ldo2_consumers),
	.consumer_supplies = ldo2_consumers,
};

/* machine regulator devices with thier consumers and constraints */
static struct platform_device wm8350_regulator_devices[] = {
{
	.name = "wm8350-regulator",
	.id = WM8350_LDO_2,
	.dev = {
		.platform_data = &ldo2_data,
	},
},
};

Changes in detail:-

  o Removed all const char* regulator config functions in machine API.
  o Created new struct regulator_init_data to contain regulator
    machine configuration constraints and consmuers.
  o Changed set_supply(), set_machine_constraints(),
    set_consumer_device_supply() to remove their string identifier
    parameters. Also made them static and moved functions nearer top of
    core.c.
  o Removed no longer used inline func to_rdev()
  o Added regulator_get_init_drvdata() to retrieve init data.
  o Added struct device* as parameter to regulator_register().
  o Changed my email address.

 to the 'Vcc' supply for Consumer A.

-               +-> [Consumer B @ 3.3V]
+Constraints can now be registered by defining a struct regulator_init_data
+for each regulator power domain. This structure also maps the consumers
+to their supply regulator :-
+
+static struct regulator_init_data regulator1_data = {

+	},
+	.num_consumer_supplies = ARRAY_SIZE(regulator1_consumers),
+	.consumer_supplies = regulator1_consumers,
+};
 
 Regulator-1 supplies power to Regulator-2. This relationship must be registered
 with the core so that Regulator-1 is also enabled when Consumer A enables it's
-supply (Regulator-2).
-
-This relationship can be register with the core via :-
-
-int regulator_set_supply(const char *regulator, const char *regulator_supply);
-
-In this example we would use the following code :-
-
-regulator_set_supply("Regulator-2", "Regulator-1");
-
-Relationships can be queried by calling :-
-
-const char *regulator_get_supply(const char *regulator);
-
-
-3. Power Domain constraint setting.
-===================================
-Each power domain within a system has physical constraints on voltage and
-current. This must be defined in software so that the power domain is always
-operated within specifications.
-
-Consider the following machine (again) :-
-
-  Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
-               |

-
-This gives us two regulators and two power domains:
-
-                   Domain 1: Regulator-2, Consumer B.
-                   Domain 2: Consumer A.
-
-Constraints can be registered by calling :-
-
-int regulator_set_platform_constraints(const char *regulator,
-	struct regulation_constraints *constraints);
-
-The example is defined as follows :-
-
-struct regulation_constraints domain_1 = {

+	.constraints = {
+		.min_uV = 1800000,

Subject: mfd: Core support for the WM8400 AudioPlus HiFi CODEC and PMU

The WM8400 is a highly integrated audio CODEC and power management unit
optimised for use in mobile multimedia applications.  This patch adds
core support for the WM8400 to the MFD subsystem.

Both I2C and SPI access are supported by the hardware but currently only
I2C access is implemented.  The code is structured to allow SPI support
to be slotted in later.

Subject: regulator: Add WM8400 regulator support

The WM8400 provides two programmable DCDC step-down (buck) convertors
and four low-dropout (LDO) regulators. This driver provides support for
runtime managment of these in the standard regulator API.

Support for configuration of the suspend and hibernate mode behaviour
of the regulators is not yet included.

Subject: mfd: Core support for the WM8350 AudioPlus PMIC

The WM8350 is an integrated audio and power management subsystem
intended for use as the primary PMIC in mobile multimedia applications.
The WM8350 can be controlled via either I2C or SPI - the control
interface is provided by a separate module in order to allow greatest
flexibility in configuring the kernel.

This driver was originally written by Liam Girdwood and has since been
updated to current kernel APIs and split up for submission by me.  All
the heavy lifting here was done by Liam.

Subject: mfd: Add GPIO pin configuration support for WM8350

The WM8350 provides a number of user-configurable pins providing access
to various signals generated by the functions on the chip. These are
referred to as GPIO pins in the device documentation but in Linux terms
they are more general than that, providing configuration of alternate
functions.

This patch implements support for selecting the alternate functions for
these pins. They can also be used as GPIOs in the normal Linux sense -
a subsequent patch will add support for doing so.

This code was all written by Liam Girdwood and has had minor updates
and rearrangements by Mark Brown.

Subject: mfd: Add initialisation callback for WM8350

Some functions of the WM8350 require board-specific initialisation on
startup. Provide a callback to the WM8350 driver in platform data
for platforms to use to configure the chip.  Use of a callback allows
platforms to control the ordering of initialisation which can be
important.

Subject: mfd: Add WM8350 interrupt support

The WM8350 has an interrupt line to the CPU which is shared by the
devices on the CPU. This patch adds support for the interrupt
controller within the WM8350 which identifies which identifies the
interrupt cause. In common with other similar chips this is done
outside the standard interrupt framework due to the need to access
the interrupt controller over an interrupt-driven bus.

This code was all originally written by Liam Girdwood with updates for
submission by me.

Subject: regulator: Add WM8350 regulator support

The WM8350 features six DCDC convertors (four buck and two boost), four
LDO voltage regulators and two constant current sinks. This driver adds
support for these through the regulator API.

This driver was written by Liam Girdwood with updates for submission
from Mark Brown.

From add41cb46175618fd42bc1ca07fe7f9dd38bf702 Mon Sep 17 00:00:00 2001
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
Date: Mon, 13 Oct 2008 15:45:22 +0100
Subject: mfd: Add placeholders for WM8350 client devices

In order to avoid merge problems further down the line add placeholders
for several of the WM8350 client devices and register them, otherwise
the patches adding the client devices will all try to update the same
code.

Also remove redundant checks for null regulator platform devices while
we're at it.

Subject: ocfs2: POSIX file locks support

This is actually pretty easy since fs/dlm already handles the bulk of the
work. The Ocfs2 userspace cluster stack module already uses fs/dlm as the
underlying lock manager, so I only had to add the right calls.

Cluster-aware POSIX locks ("plocks") can be turned off by the same means at
UNIX locks - mount with 'noflocks', or create a local-only Ocfs2 volume.
Internally, the file system uses two sets of file_operations, depending on
whether cluster aware plocks is required. This turns out to be easier than
implementing local-only versions of ->lock.

Subject: ocfs2: Track local alloc bits internally

Do this instead of tracking absolute local alloc size. This avoids
needless re-calculatiion of bits from bytes in localalloc.c. Additionally,
the value is now in a more natural unit for internal file system bitmap
work.

Subject: ocfs2: throttle back local alloc when low on disk space

Ocfs2's local allocator disables itself for the duration of a mount point
when it has trouble allocating a large enough area from the primary bitmap.
That can cause performance problems, especially for disks which were only
temporarily full or fragmented. This patch allows for the allocator to
shrink it's window first, before being disabled. Later, it can also be
re-enabled so that any performance drop is minimized.

To do this, we allow the value of osb->local_alloc_bits to be shrunk when
needed. The default value is recorded in a mostly read-only variable so that
we can re-initialize when required.

Locking had to be updated so that we could protect changes to
local_alloc_bits. Mostly this involves protecting various local alloc values
with the osb spinlock. A new state is also added, OCFS2_LA_THROTTLED, which
is used when the local allocator is has shrunk, but is not disabled. If the
available space dips below 1 megabyte, the local alloc file is disabled. In
either case, local alloc is re-enabled 30 seconds after the event, or when
an appropriate amount of bits is seen in the primary bitmap.

Subject: ocfs2: track local alloc state via debugfs

A per-mount debugfs file, "local_alloc" is created which when read will
expose live state of the nodes local alloc file. Performance impact is
minimal, only a bit of memory overhead per mount point. Still, the code is
hidden behind CONFIG_OCFS2_FS_STATS. This feature will help us debug
local alloc performance problems on a live system.

Subject: ocfs2: Modify ocfs2_num_free_extents for future xattr usage.

ocfs2_num_free_extents() is used to find the number of free extent records
in an inode btree. Hence, it takes an "ocfs2_dinode" parameter. We want to
use this for extended attribute trees in the future, so genericize the
interface the take a buffer head. A future patch will allow that buffer_head
to contain any structure rooting an ocfs2 btree.

Subject: ocfs2: Use ocfs2_extent_list instead of ocfs2_dinode.

ocfs2_extend_meta_needed(), ocfs2_calc_extend_credits() and
ocfs2_reserve_new_metadata() are all useful for extent tree operations. But
they are all limited to an inode btree because they use a struct
ocfs2_dinode parameter. Change their parameter to struct ocfs2_extent_list
(the part of an ocfs2_dinode they actually use) so that the xattr btree code
can use these functions.

From e7d4cb6bc19658646357eeff134645cd9bc3479f Mon Sep 17 00:00:00 2001
From: Tao Ma <tao.ma@oracle.com>
Date: Mon, 18 Aug 2008 17:38:44 +0800
Subject: ocfs2: Abstract ocfs2_extent_tree in b-tree operations.

In the old extent tree operation, we take the hypothesis that we
are using the ocfs2_extent_list in ocfs2_dinode as the tree root.
As xattr will also use ocfs2_extent_list to store large value
for a xattr entry, we refactor the tree operation so that xattr
can use it directly.

The refactoring includes 4 steps:
1. Abstract set/get of last_eb_blk and update_clusters since they may
   be stored in different location for dinode and xattr.
2. Add a new structure named ocfs2_extent_tree to indicate the
   extent tree the operation will work on.
3. Remove all the use of fe_bh and di, use root_bh and root_el in
   extent tree instead. So now all the fe_bh is replaced with
   et->root_bh, el with root_el accordingly.
4. Make ocfs2_lock_allocators generic. Now it is limited to be only used
   in file extend allocation. But the whole function is useful when we want
   to store large EAs.

Note: This patch doesn't touch ocfs2_commit_truncate() since it is not used
for anything other than truncate inode data btrees.

Subject: ocfs2: Make high level btree extend code generic

Factor out the non-inode specifics of ocfs2_do_extend_allocation() into a more generic
function, ocfs2_do_cluster_allocation(). ocfs2_do_extend_allocation calls
ocfs2_do_cluster_allocation() now, but the latter can be used for other
btree types as well.

Subject: ocfs2: Add the basic xattr disk layout in ocfs2_fs.h

Ocfs2 uses a very flexible structure for storing extended attributes on
disk. Small amount of attributes are stored directly in the inode block - up
to 256 bytes worth. If that fills up, attributes are also stored in an
external block, linked to from the inode block. That block can in turn
expand to a btree, capable of storing large numbers of attributes.

Individual attribute values are stored inline if they're small enough
(currently about 80 bytes, this can be changed though), and otherwise are
expanded to a btree. The theoretical limit to the size of an individual
attribute is about the same as an inode, though the kernel's upper bound on
the size of an attributes data is far smaller.

Subject: ocfs2: Add helper function in uptodate.c for removing xattr clusters

The old uptodate only handles the issue of removing one buffer_head from
ocfs2 inode's buffer cache. With xattr clusters, we may need to remove
multiple buffer_head's at a time.

Subject: Staging: workaround build system bug

This is needed as CONFIG_STAGING is set to y, yet there is no code in
drivers/staging/ to build, so the build-in.o doesn't get created
properly.  Create a "dummy" module in drivers/staging called staging.c
to work around this bug.

Subject: staging: at76_usb wireless driver

Add the at76_usb wireless driver to the staging tree while the
other kernel driver (out of tree) gets rewritten to use the internal
wireless stack.

This patch comes directly from the Fedora kernel tree, with only the
directory placement of the files changed.

Subject: powerpc: Fix DMA offset for non-coherent DMA

After Becky's work we can almost have different DMA offsets
between on-chip devices and PCI. Almost because there's a
problem with the non-coherent DMA code that basically ignores
the programmed offset to use the global one for everything.
This fixes it.

Subject: powerpc: Get USE_STRICT_MM_TYPECHECKS working again

The typesafe version of the powerpc pagetable handling (with
USE_STRICT_MM_TYPECHECKS defined) has bitrotted again.  This patch
makes a bunch of small fixes to get it back to building status.

It's still not enabled by default as gcc still generates worse
code with it for some reason.

last is for the xattr index btree, which will be used in a followup patch.

All the old callers in file.c etc will call ocfs2_dinode_insert_extent(),
while the other two handle the xattr issue. And the init of extent tree are
handled by these functions.

When storing xattr value which is too large, we will allocate some clusters
for it and here ocfs2_extent_list and ocfs2_extent_rec will also be used. In
order to re-use the b-tree operation code, a new parameter named "private"
is added into ocfs2_extent_tree and it is used to indicate the root of
ocfs2_exent_list. The reason is that we can't deduce the root from the
buffer_head now. It may be in an inode, an ocfs2_xattr_block or even worse,
in any place in an ocfs2_xattr_bucket.

From fdd77704a8b4666a32120fcd1e4a9fedaf3263d8 Mon Sep 17 00:00:00 2001
From: Tiger Yang <tiger.yang@oracle.com>
Date: Mon, 18 Aug 2008 17:08:55 +0800
Subject: ocfs2: reserve inline space for extended attribute

Add the structures and helper functions we want for handling inline extended
attributes. We also update the inline-data handlers so that they properly
function in the event that we have both inline data and inline attributes
sharing an inode block.

From cf1d6c763fbcb115263114302485ad17e7933d87 Mon Sep 17 00:00:00 2001
From: Tiger Yang <tiger.yang@oracle.com>
Date: Mon, 18 Aug 2008 17:11:00 +0800
Subject: ocfs2: Add extended attribute support

This patch implements storing extended attributes both in inode or a single
external block. We only store EA's in-inode when blocksize > 512 or that
inode block has free space for it. When an EA's value is larger than 80
bytes, we will store the value via b-tree outside inode or block.

From ba492615f0d32d0210b02c14b24512b4372b13d6 Mon Sep 17 00:00:00 2001
From: Tao Ma <tao.ma@oracle.com>
Date: Mon, 18 Aug 2008 17:38:49 +0800
Subject: ocfs2: Add xattr index tree operations

When necessary, an ocfs2_xattr_block will embed an ocfs2_extent_list to
store large numbers of EAs. This patch adds a new type in
ocfs2_extent_tree_type and adds the implementation so that we can re-use the
b-tree code to handle the storage of many EAs.

Subject: ocfs2: Add xattr bucket iteration for large numbers of EAs

Ocfs2 breaks up xattr index tree leaves into 4k regions, called buckets.
Attributes are stored within a given bucket, depending on hash value.

After a discussion with Mark, we decided that the per-bucket index
(xe_entry[]) would only exist in the 1st block of a bucket. Likewise,
name/value pairs will not straddle more than one block. This allows the
majority of operations to work directly on the buffer heads in a leaf block.

This patch adds code to iterate the buckets in an EA. A new abstration of
ocfs2_xattr_bucket is added. It records the bhs in this bucket and
ocfs2_xattr_header. This keeps the code neat, improving readibility.

Subject: ocfs2: Add xattr lookup code xattr btrees

Add code to lookup a given extended attribute in the xattr btree. Lookup
follows this general scheme:

1. Use ocfs2_xattr_get_rec to find the xattr extent record

2. Find the xattr bucket within the extent which may contain this xattr

3. Iterate the bucket to find the xattr. In ocfs2_xattr_block_get(), we need
   to recalcuate the block offset and name offset for the right position of
   name/value.

Subject: ocfs2: Optionally limit extent size in ocfs2_insert_extent()

In xattr bucket, we want to limit the maximum size of a btree leaf,
otherwise we'll lose the benefits of hashing because we'll have to search
large leaves.

So add a new field in ocfs2_extent_tree which indicates the maximum leaf cluster
size we want so that we can prevent ocfs2_insert_extent() from merging the leaf
record even if it is contiguous with an adjacent record.

Other btree types are not affected by this change.

Subject: ocfs2: Enable xattr set in index btree

Where the previous patches added the ability of list/get xattr in buckets
for ocfs2, this patch enables ocfs2 to store large numbers of EAs.

The original design doc is written by Mark Fasheh, and it can be found in
http://oss.oracle.com/osswiki/OCFS2/DesignDocs/IndexedEATrees. I only had to
make small modifications to it.

First, because the bucket size is 4K, a new field named xh_free_start is added
in ocfs2_xattr_header to indicate the next valid name/value offset in a bucket.
It is used when we store new EA name/value. With this field, we can find the
place more quickly and what's more, we don't need to sort the name/value every
time to let the last entry indicate the next unused space. This makes the
insert operation more efficient for blocksizes smaller than 4k.

Because of the new xh_free_start, another field named as xh_name_value_len is
also added in ocfs2_xattr_header. It records the total length of all the
name/values in the bucket. We need this so that we can check it and defragment
the bucket if there is not enough contiguous free space.

An xattr insertion looks like this:
1. xattr_index_block_find: find the right bucket by the name_hash, say bucketA.
2. check whether there is enough space in bucketA. If yes, insert it directly
   and modify xh_free_start and xh_name_value_len accordingly. If not, check
   xh_name_value_len to see whether we can store this by defragment the bucket.
   If yes, defragment it and go on insertion.
3. If defragement doesn't work, check whether there is new empty bucket in
   the clusters within this extent record. If yes, init the new bucket and move
   all the buckets after bucketA one by one to the next bucket. Move half of the
   entries in bucketA to the next bucket and go on insertion.
4. If there is no new bucket, grow the extent tree.

As for xattr deletion, we will delete an xattr bucket when all it's xattrs
are removed and move all the buckets after it to the previous one. When all
the xattr buckets in an extend record are freed, free this extend records
from ocfs2_xattr_tree.

Subject: ocfs2: Add incompatible flag for extended attribute

This patch adds the s_incompat flag for extended attribute support. This
helps us ensure that older versions of Ocfs2 or ocfs2-tools will not be able
to mount a volume with xattr support.

Subject: ocfs2: Prefix the extent tree operations structure.

The ocfs2_extent_tree_operations structure gains a field prefix on its
members.  The ->eo_sanity_check() operation gains a wrapper function for
completeness.  All of the extent tree operation wrappers gain a
consistent name (ocfs2_et_*()).

Rather than allocating a struct ocfs2_extent_tree, just put it on the
stack.  Fill it with ocfs2_get_extent_tree() and drop it with
ocfs2_put_extent_tree().  Now the callers don't have to ENOMEM, yet
still safely ref the root_bh.

Subject: ocfs2: Make 'private' into 'object' on ocfs2_extent_tree.

The 'private' pointer was a way to store off xattr values, which don't
live at a set place in the bh.  But the concept of "the object
containing the extent tree" is much more generic.  For an inode it's the
struct ocfs2_dinode, for an xattr value its the value.  Let's save off
the 'object' at all times.  If NULL is passed to
ocfs2_get_extent_tree(), 'object' is set to bh->b_data;

Subject: ocfs2: Provide the get_root_el() method to
 ocfs2_extent_tree_operations.

The root_el of an ocfs2_extent_tree needs to be calculated from
et->et_object.  Make it an operation on et->et_ops.

Subject: ocfs2: Use struct ocfs2_extent_tree in ocfs2_num_free_extents().

ocfs2_num_free_extents() re-implements the logic of
ocfs2_get_extent_tree().  Now that ocfs2_get_extent_tree() does not
allocate, let's use it in ocfs2_num_free_extents() to simplify the code.

The inode validation code in ocfs2_num_free_extents() is not needed.
All callers are passing in pre-validated inodes.

From: Joel Becker <joel.becker@oracle.com>
Date: Wed, 20 Aug 2008 17:44:24 -0700
Subject: ocfs2: Create specific get_extent_tree functions.

A caller knows what kind of extent tree they have.  There's no reason
they have to call ocfs2_get_extent_tree() with a NULL when they could
just as easily call a specific function to their type of extent tree.

Introduce ocfs2_dinode_get_extent_tree(),
ocfs2_xattr_tree_get_extent_tree(), and
ocfs2_xattr_value_get_extent_tree().  They only take the necessary
arguments, calling into the underlying __ocfs2_get_extent_tree() to do
the real work.

__ocfs2_get_extent_tree() is the old ocfs2_get_extent_tree(), but
without needing any switch-by-type logic.

ocfs2_get_extent_tree() is now a wrapper around the specific calls.  It
exists because a couple alloc.c functions can take et_type.  This will
go later.

Another benefit is that ocfs2_xattr_value_get_extent_tree() can take a
struct ocfs2_xattr_value_root* instead of void*.  This gives us
typechecking where we didn't have it before.

Subject: ocfs2: Add an insertion check to ocfs2_extent_tree_operations.

A couple places check an extent_tree for a valid inode.  We move that
out to add an eo_insert_check() operation.  It can be called from
ocfs2_insert_extent() and elsewhere.

We also have the wrapper calls ocfs2_et_insert_check() and
ocfs2_et_sanity_check() ignore NULL ops.  That way we don't have to
provide useless operations for xattr types.

From f99b9b7ccf6a691f653cec45f36bfdd1e94769c7 Mon Sep 17 00:00:00 2001
From: Joel Becker <joel.becker@oracle.com>
Date: Wed, 20 Aug 2008 19:36:33 -0700
Subject: ocfs2: Make ocfs2_extent_tree the first-class representation of a
 tree.

We now have three different kinds of extent trees in ocfs2: inode data
(dinode), extended attributes (xattr_tree), and extended attribute
values (xattr_value).  There is a nice abstraction for them,
ocfs2_extent_tree, but it is hidden in alloc.c.  All the calling
functions have to pick amongst a varied API and pass in type bits and
often extraneous pointers.

A better way is to make ocfs2_extent_tree a first-class object.
Everyone converts their object to an ocfs2_extent_tree() via the
ocfs2_get_*_extent_tree() calls, then uses the ocfs2_extent_tree for all
tree calls to alloc.c.

This simplifies a lot of callers, making for readability.  It also
provides an easy way to add additional extent tree types, as they only
need to be defined in alloc.c with a ocfs2_get_<new>_extent_tree()
function.

Subject: ocfs2: Comment struct ocfs2_extent_tree_operations.

struct ocfs2_extent_tree_operations provides methods for the different
on-disk btrees in ocfs2.  Describing what those methods do is probably a
good idea.

Date: Fri, 22 Aug 2008 12:46:09 -0700
Subject: ocfs2: Change ocfs2_get_*_extent_tree() to ocfs2_init_*_extent_tree()

The original get/put_extent_tree() functions held a reference on
et_root_bh.  However, every single caller already has a safe reference,
making the get/put cycle irrelevant.

We change ocfs2_get_*_extent_tree() to ocfs2_init_*_extent_tree().  It
no longer gets a reference on et_root_bh.  ocfs2_put_extent_tree() is
removed.  Callers now have a simpler init+use pattern.

Subject: ocfs2: bug-fix for journal extend in xattr.

In ocfs2_extend_trans, when we can't extend the current
transaction, it will commit current transaction and restart
a new one. So if the previous credits we have allocated aren't
used(the block isn't dirtied before our extend), we will not
have enough credits for any future operation(it will cause jbd
complain and bug out). So check this and re-extend it.

Subject: ocfs2: Resolve deadlock in ocfs2_xattr_free_block.

In ocfs2_xattr_free_block, we take a cluster lock on xb_alloc_inode while we
have a transaction open. This will deadlock the downconvert thread, so fix
it.

We can clean up how xattr blocks are removed while here - this patch also
moves the mechanism of releasing xattr block (including both value, xattr
tree and xattr block) into this function.

From: Joel Becker <joel.becker@oracle.com>

Subject: ocfs2: Limit inode allocation to 32bits.

ocfs2 inode numbers are block numbers.  For any filesystem with less
than 2^32 blocks, this is not a problem.  However, when ocfs2 starts
using JDB2, it will be able to support filesystems with more than 2^32
blocks.  This would result in inode numbers higher than 2^32.

The problem is that stat(2) can't handle those numbers on 32bit
machines.  The simple solution is to have ocfs2 allocate all inodes
below that boundary.

The suballoc code is changed to honor an optional block limit.  Only the
inode suballocator sets that limit - all other allocations stay unlimited.

The biggest trick is to grow the inode suballocator beneath that limit.
There's no point in allocating block groups that are above the limit,
then rejecting their elements later on.  We want to prevent the inode
allocator from ever having block groups above the limit.  This involves
a little gyration with the local alloc code.  If the local alloc window
is above the limit, it signals the caller to try the global bitmap but
does not disable the local alloc file (which can be used for other
allocations).

Subject: ocfs2: Add the 'inode64' mount option.

Now that ocfs2 limits inode numbers to 32bits, add a mount option to
disable the limit.  This parallels XFS.  64bit systems can handle the
larger inode numbers.

[ Added description of inode64 mount option in ocfs2.txt. --Mark ]

From: Joel Becker <joel.becker@oracle.com>

Subject: ocfs2: Switch over to JBD2.

ocfs2 wants JBD2 for many reasons, not the least of which is that JBD is
limiting our maximum filesystem size.

It's a pretty trivial change.  Most functions are just renamed.  The
only functional change is moving to Jan's inode-based ordered data mode.
It's better, too.

Because JBD2 reads and writes JBD journals, this is compatible with any
existing filesystem.  It can even interact with JBD-based ocfs2 as long
as the journal is formated for JBD.

We provide a compatibility option so that paranoid people can still use
JBD for the time being.  This will go away shortly.

[ Moved call of ocfs2_begin_ordered_truncate() from ocfs2_delete_inode() to
  ocfs2_truncate_for_delete(). --Mark ]

Subject: ocfs2/xattr.c: Fix a bug when inserting xattr.

During the process of xatt insertion, we use binary search
to find the right place and "low" is set to it. But when
there is one xattr which has the same name hash as the inserted
one, low is the wrong value. So set it to the right position.

Subject: ocfs2: Add empty bucket support in xattr.

As Mark mentioned, it may be time-consuming when we remove the
empty xattr bucket, so this patch try to let empty bucket exist
in xattr operation. The modification includes:
1. Remove the functin of bucket and extent record deletion during
   xattr delete.
2. In xattr set:
   1) Don't clean the last entry so that if the bucket is empty,
      the hash value of the bucket is the hash value of the entry
      which is deleted last.
   2) During insert, if we meet with an empty bucket, just use the
      1st entry.
3. In binary search of xattr bucket, use the bucket hash value(which
   stored in the 1st xattr entry) to find the right place.

Subject: ocfs2: use smaller counters in ocfs2_remove_xattr_clusters_from_cache

i and b_len don't really need to be u64's. Xattr extent lengths should be
limited by the VFS, and then the size of our on-disk length field.

Subject: ocfs2: Move trusted and user attribute support into xattr.c

Per Christoph Hellwig's suggestion - don't split these up. It's not like we
gained much by having the two tiny files around.

Subject: ocfs2: Refactor xattr list and remove ocfs2_xattr_handler().

According to Christoph Hellwig's advice, we really don't need
a ->list to handle one xattr's list. Just a map from index to
xattr prefix is enough. And I also refactor the old list method
with the reference from fs/xfs/linux-2.6/xfs_xattr.c and the
xattr list method in btrfs.

tell the VFS that seeks are not supported.

Subject: de2104x: wrong MAC address fix

The de2104x returns sometimes a wrong MAC address. The wrong one is
like the original one, but it comes with an one byte shift. I found
this bug on an older alpha ev5 cpu. More details are available in Gentoo
bugreport #240718.

It seems the hardware is sometimes a little bit too slow for an
immediate access. This patch solves the problem by introducing a small
udelay.

Thinkpad R31 needs i8042 nomux quirk.  Stops jittery jumping mouse
and random keyboard input. Fixes kernel bug #11723.  Cherry picked
from Ubuntu who have sometimes (on-again-off-again) had a fix in
their patched kernels.

Subject: ALSA: ASoC: Hide TLV320AIC26 configuration option for
 non-OpenFirwmare users

Make the visibility of the tristate conditional on having the OpenFirmware
helper code enabed so that users who can't use it don't see the visible
option. Kconfig ignores dependencies for select so other users are
unaffected.

Thanks to Takashi for the suggestion.

Subject: ALSA: Fix pxa2xx-ac97-lib.c compilation

The last ALSA merge broke pxa2xx-ac97-lib.c, as it brought back
references to cpu_is_pxa21x that Eric Miao removed in commit
0ffcbfd54ea81ca24c0749f55ca4fcf3e2bdc23e:

	[ARM] pxa: make cpu_is_pxa2* macros more consistent

This patch gets rid of those references, and only keeps cpu_is_pxa25x().

Subject: vfs: Remove the range_cont writeback mode.

Ext4 was the only user of range_cont writeback mode and ext4 switched
to a different method. So remove the range_cont mode which is not used
in the kernel.

Subject: do_generic_file_read: s/EINTR/EIO/ if lock_page_killable() fails

If lock_page_killable() fails because the task was killed by SIGKILL or
any other fatal signal, do_generic_file_read() returns -EIO.

This seems to be OK, because in fact the userspace won't see this error,
the task will dequeue SIGKILL and exit.

However, /sbin/init is different, it will dequeue SIGKILL, ignore it, and
return to the user-space with the bogus -EIO.

Change the code to return the error code from lock_page_killable(), -EINTR.
This doesn't fix the bug, but perhaps makes sense anyway. Imho, with this
change the code looks a bit more logical, and the "good" init should handle
the spurious EINTR or short read.

Afaics we can also change lock_page_killable() to return -ERESTARTNOINTR,
but this can't prevent the short reads.

Based on David Brownell's patch for tps65010 and previous work by
Felipe Balbi, this patch finishes converting isp1301_omap to a
new-style i2c driver.

There's definitely room for further drivers cleanups, but these are
out of the scope of this patch.

Subject: i2c-pca-isa: Don't grab arbitrary resources

Grabbing ISA bus resources without anything or anyone telling us we
should can break boot on randconfig/allyesconfig builds by keeping
resources that are in fact owned by different hardware busy and does
as reported by Ingo Molnar.

Generally it's also dangerous to just poke at random I/O ports and
especially those in the range where other old easily confused ISA
hardware might live.

For this specialized I2C bus driver, insist that the user specifies
the resources before grabbing them.

The^WA user of this driver is a one time

echo "options i2c-pca-isa base=0x330 irq=10" >> /etc/modprobe.conf

away from the old behaviour.

Subject: i2c: Renesas Highlander FPGA SMBus support

This adds support for the SMBus adapter found in the various FPGAs on
the Renesas Highlander platforms. Particularly the R0P7780LC0011RL and
R0P7785LC0011RL FPGAs.

Functionality is fairly restricted, in that only byte and block data
transfers are supported. Normal/fast mode and IRQ/polling are also
supported. Primarily used for various RTCs and thermal sensors.

All the tps6501{0,1,2,3,4} chips have a signal for hooking up with
a vibrator (for non-auditory cell phone "ring") ... expose that as
one more (output-only) GPIO.

Subject: hwmon: (dme1737) Be less i2c-centric

The dme1737 driver support both LPC (ISA) and SMBus devices. At the
moment it's rather i2c-centric, and LPC variants use a fake i2c_client
for some operations.

In a near future, i2c_client will be allocated by i2c-core rather than
by the device drivers, so non-i2c drivers will not have one. As a
preparation step, change the driver code to no longer assume that
an i2c_client structure is always available. No functional change.

Subject: hwmon: (dme1737) Convert to a new-style i2c driver

The new-style dme1737 driver implements the optional detect() callback
to cover the use cases of the legacy driver. I don't actually expect
any new-style device for that driver, but as the old i2c API is going
away soon, we have to switch to the new one.

Subject: i2c-parport-light: Don't register a platform device resource

The i2c-parport-light driver isn't a real platform driver, so it
should not instantiate platform devices with resources. The resource
management system can't cope with colliding resources, and we are
likely to create such a colliding resource.

So, better just try to grab the I/O ports we need right at module
initialization time, and bail out if we can't. It has the added
benefit that the module will no longer load if it isn't going to work,
which is definitely more user-friendly.

+
+
+Implementation details
+======================
+
+For the interested, here's the code flow which happens inside the kernel
+when you use the /dev interface to I2C:
+
+1* Your program opens /dev/i2c-N and calls ioctl() on it, as described in
+section "C example" above.
+
+2* These open() and ioctl() calls are handled by the i2c-dev kernel
+driver: see i2c-dev.c:i2cdev_open() and i2c-dev.c:i2cdev_ioctl(),
+respectively. You can think of i2c-dev as a generic I2C chip driver
+that can be programmed from user-space.
+
+3* Some ioctl() calls are for administrative tasks and are handled by
+i2c-dev directly. Examples include I2C_SLAVE (set the address of the
+device you want to access) and I2C_PEC (enable or disable SMBus error
+checking on future transactions.)
+
+4* Other ioctl() calls are converted to in-kernel function calls by
+i2c-dev. Examples include I2C_FUNCS, which queries the I2C adapter
+functionality using i2c.h:i2c_get_functionality(), and I2C_SMBUS, which
+performs an SMBus transaction using i2c-core.c:i2c_smbus_xfer().
+
+The i2c-dev driver is responsible for checking all the parameters that
+come from user-space for validity. After this point, there is no
+difference between these calls that came from user-space through i2c-dev
+and calls that would have been performed by kernel I2C chip drivers
+directly. This means that I2C bus drivers don't need to implement
+anything special to support access from user-space.
+
+5* These i2c-core.c/i2c.h functions are wrappers to the actual
+implementation of your I2C bus driver. Each adapter must declare
+callback functions implementing these standard calls.
+i2c.h:i2c_get_functionality() calls i2c_adapter.algo->functionality(),
+while i2c-core.c:i2c_smbus_xfer() calls either
+adapter.algo->smbus_xfer() if it is implemented, or if not,
+i2c-core.c:i2c_smbus_xfer_emulated() which in turn calls
+i2c_adapter.algo->master_xfer().
+
+After your I2C bus driver has processed these requests, execution runs
+up the call chain, with almost no processing done, except by i2c-dev to
+package the returned data, if any, in suitable format for the ioctl.

Subject: i2c: Guard against oopses from bad init sequences

Guard I2C against oopsing because of init sequence problems, by
verifying that i2c_init() has been called before calling any
routines that rely on that initialization.  This specific test
just requires that bus_register(&i2c_bus_type) was called.

Examples of this kind of oopsing come from subystems and drivers
which register I2C drivers in their subsys_initcall code but
which are statically linked before I2C by drivers/Makefile.

Move I2C driver model init earlier in the boot sequence.

This avoids oopsing in statically linked systems when some
subsystems register I2C drivers in subsys_initcall() code,
but those subsystems are linked (and initialized) before I2C.

From 5b1d5f953bbb50dcbdf93719cb622aa128ba7527 Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@kernel.org>
Date: Mon, 13 Oct 2008 21:58:47 +0200
Subject: m68k: use bcd2bin/bin2bcd

This patch changes m68k to use the new bcd2bin/bin2bcd functions instead
of the obsolete BCD_TO_BIN/BIN_TO_BCD/BCD2BIN/BIN2BCD macros.

It also remove local bcd2bin/bin2bcd implementations
in favor of the global ones.

Subject: m68k: Reverse platform MMU logic so Sun 3 is last

Currently Sun 3 support is the first platform option, as the Sun 3 MMU is
incompatible with standard Motorola MMUs. However, this means that
`allmodconfig' enables support for Sun 3, and thus disables support for all
other platforms.

Reverse the logic and move Sun 3 last, so `allmodconfig' enables all
platforms except for Sun 3, increasing compile-coverage.

Subject: m68k: Define rtc_lock on Atari

The nvram and rtc-cmos drivers use the spinlock rtc_lock to protect against
concurrent accesses to the CMOS memory. As m68k doesn't support SMP or preempt
yet, the spinlock calls tend to get optimized away, but not for all
configurations, causing in some rare cases:

| ERROR: "rtc_lock" [drivers/rtc/rtc-cmos.ko] undefined!
| ERROR: "rtc_lock" [drivers/char/nvram.ko] undefined!

Add the spinlock to the Atari core code to avoid this.

- * 
- * This code emulates TT SCSI DMA on the Hades.
- * 
- * Note the following:
- * 
- * 1. When there is no byte available to read from the SCSI bus, or
- *    when a byte cannot yet bet written to the SCSI bus, a bus
- *    error occurs when reading or writing the pseudo DMA data
- *    register (hades_psdm_reg). We have to catch this bus error
- *    and try again to read or write the byte. If after several tries
- *    we still get a bus error, the interrupt handler is left. When
- *    the byte can be read or written, the interrupt handler is
- *    called again.
- * 
- * 2. The SCSI interrupt must be disabled in this interrupt handler.
- * 
- * 3. If we set the EOP signal, the SCSI controller still expects one
- *    byte to be read or written. Therefore the last byte is transferred
- *    separately, after setting the EOP signal.
- * 
- * 4. When this function is left, the address pointer (start_addr) is
- *    converted to a physical address. Because it points one byte
- *    further than the last transferred byte, it can point outside the
- *    current page. If virt_to_phys() is called with this address we
- *    might get an access error. Therefore virt_to_phys() is called with
- *    start_addr - 1 if the count has reached zero. The result is
- *    increased with one.

Subject: m68k: init_irq_proc depends on CONFIG_PROC_FS

If CONFIG_PROC_FS is not set, I get:

| arch/m68k/kernel/ints.c:433: error: redefinition of 'init_irq_proc'
| include/linux/interrupt.h:438: error: previous definition of 'init_irq_proc' was here

This was introduced by commit 6168a702ab0be181e5e57a0b2d0e7376f7a47f0b
("Declare init_irq_proc before we use it."), which replaced the #ifdef
protection of the init_irq_proc() call by a static inline dummy if
CONFIG_PROC_FS is not set.

Make init_irq_proc() depend on CONFIG_PROC_FS to fix this.

Subject: ocfs2: Separate out sync reads from ocfs2_read_blocks()

The ocfs2_read_blocks() function currently handles sync reads, cached,
reads, and sometimes cached reads.  We're going to add some
functionality to it, so first we should simplify it.  The uncached,
synchronous reads are much easer to handle as a separate function, so we
instroduce ocfs2_read_blocks_sync().

Subject: ocfs2: Require an inode for ocfs2_read_block(s)().

Now that synchronous readers are using ocfs2_read_blocks_sync(), all
callers of ocfs2_read_blocks() are passing an inode.  Use it
unconditionally.  Since it's there, we don't need to pass the
ocfs2_super either.

From 0fcaa56a2a020dd6f90c202b7084e6f4cbedb6c2 Mon Sep 17 00:00:00 2001
From: Joel Becker <joel.becker@oracle.com>
Date: Thu, 9 Oct 2008 17:20:31 -0700
Subject: ocfs2: Simplify ocfs2_read_block()

More than 30 callers of ocfs2_read_block() pass exactly OCFS2_BH_CACHED.
Only six pass a different flag set.  Rather than have every caller care,
let's make ocfs2_read_block() take no flags and always do a cached read.
The remaining six places can call ocfs2_read_blocks() directly.

Subject: netfilter: restore lost #ifdef guarding defrag exception

Nir Tzachar <nir.tzachar@gmail.com> reported a warning when sending
fragments over loopback with NAT:

[ 6658.338121] WARNING: at net/ipv4/netfilter/nf_nat_standalone.c:89 nf_nat_fn+0x33/0x155()

The reason is that defragmentation is skipped for already tracked connections.
This is wrong in combination with NAT and ip_conntrack actually had some ifdefs
to avoid this behaviour when NAT is compiled in.

The entire "optimization" may seem a bit silly, for now simply restoring the
lost #ifdef is the easiest solution until we can come up with something better.

Subject: ocfs2: Kill the last naked wait_on_buffer() for cached reads.

ocfs2's cached buffer I/O goes through ocfs2_read_block(s)().  dir.c had
a naked wait_on_buffer() to wait for some readahead, but it should
use ocfs2_read_block() instead.

Subject: ocfs2: Make cached block reads the common case.

ocfs2_read_blocks() currently requires the CACHED flag for cached I/O.
However, that's the common case.  Let's flip it around and provide an
IGNORE_CACHE flag for the special users.  This has the added benefit of
cleaning up the code some (ignore_cache takes on its special meaning
earlier in the loop).

Subject: netfilter: ctnetlink: remove bogus module dependency between
 ctnetlink and nf_nat

This patch removes the module dependency between ctnetlink and
nf_nat by means of an indirect call that is initialized when
nf_nat is loaded. Now, nf_conntrack_netlink only requires
nf_conntrack and nfnetlink.

This patch puts nfnetlink_parse_nat_setup_hook into the
nf_conntrack_core to avoid dependencies between ctnetlink,
nf_conntrack_ipv4 and nf_conntrack_ipv6.

This patch also introduces the function ctnetlink_change_nat
that is only invoked from the creation path. Actually, the
nat handling cannot be invoked from the update path since
this is not allowed. By introducing this function, we remove
the useless nat handling in the update path and we avoid
deadlock-prone code.

This patch also adds the required EAGAIN logic for nfnetlink.

From 93f78da405685a756beeaeae4b5e41fcec39eab3 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Tue, 14 Oct 2008 12:12:02 -0700
Subject: Revert "vt: fix background color on line feed"

This reverts commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b, and the
subsequent commits that fixed it up:

 - afa9b649 "fbcon: prevent cursor disappearance after switching to 512
   character font"

 - d850a2fa "vt/fbcon: fix background color on line feed"

 - 7fe3915a "vt/fbcon: update scrl_erase_char after 256/512-glyph font
   switch"

by request of Alan Cox. Quoth Alan:
  "Unfortunately it's wrong and its been causing breakages because
   various apps like ncurses expect our previous (and correct)
   behaviour."

Alexander sent out a similar patch.

Requested-by: Alan Cox <alan@lxorguk.ukuu.org.uk>
Tested-by: Jan Engelhardt <jengelh@medozas.de>

Subject: [ARM] 5305/1: ARM: OMAP: Fix compile of McBSP by removing unnecessary
 check

Recent McBSP patches changed to allocating devices dynamically
and the check for OMAP_MAX_MCBSP_COUNT became unnecessary.

The check for OMAP_MAX_MCBSP_COUNT should have been removed with
the earlier McBSP patches in devices.c but was accidentally left
out.

Subject: HID: make a bus from hid code

Make a bus from hid core. This is the first step for converting all the
quirks and separate almost-drivers into real drivers attached to this bus.

It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.

Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at
the very rude base.

From c500c9714011edab021591340042787722db9cf0 Mon Sep 17 00:00:00 2001
From: Jiri Slaby <jirislaby@gmail.com>
Date: Fri, 16 May 2008 11:49:16 +0200
Subject: HID: hid, make parsing event driven

Next step for complete hid bus, this patch includes:
- call parser either from probe or from hid-core if there is no probe.
- add ll_driver structure and centralize some stuff there (open, close...)
- split and merge usb_hid_configure and hid_probe into several functions
  to allow hooks/fixes between them

Subject: HID: move ignore quirks

Move ignore quirks from usbhid-quirks into hid-core code. Also don't output
warning when ENODEV is error code in usbhid and try ordinal input in hidp
when that error is returned.

From 02ae9a1a8bc1d08a8fd5f6a0b8bde400b0f891b9 Mon Sep 17 00:00:00 2001
From: Jiri Slaby <jirislaby@gmail.com>
Date: Fri, 16 May 2008 11:49:22 +0200
Subject: HID: add compat support

Add compat option to hid code to allow loading of all modules on
systems which don't allow autoloading because of old userspace.

so it's useless.

force a creation of the hiddev interface, but still they
are operated by generic driver (i.e. certain UPS).

Subject: HID: remove ignore quirk for MGE UPS devices

This patch reverts the change made four years ago here:
http://www.vg.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-hid-2.4.25-pre7.patch

UPS's made by MGE can be used with usbhid just fine, and by removing the
ignore quirk allows them to be used with HAL so they just work when plugged
in, without needing to be manually configured.

With the ignore quirk in place a user would have to configure NUT before the
UPS could be used, as NUT uses it's own internal USB matching framework
to match against the USB devices, do low level control messages on the
device and then parse the HID tables all in userspace.

This is not needed, as allowing the device to be claimed as a usbhid device
allows it to be used like any other USB UPS device. The devices correctly
advertise the power device page which can be queried for the device state.

I assume the quirk was changed so that people using < libusb 0.1.8 could
still use NUT's internal HID code to manage the UPS.
libusb 0.1.8 was released quite some time ago: 2004-02-11.

This patch does not break NUT as in drivers/libusb.c the device is force
unbound from the kernel driver using usb_detach_kernel_driver_np () where
it can be controlled like normal.

Subject: HID: add support for Super Dual Box Pro USB PS2/PS2 adapter

This seems to be the very same device, as already supported Smartjoy
dual Plus, but with slightly different vendor ID. Let's support this
one too.

Subject: HID: Autocentering support for Logitech MOMO Racing Wheel

Current kernel has no support for autocentering for Logitech wheels.  By
default autocentering enabled in wheel and constant effect does not work
properly. Using USB sniffer I found command which change autocentering
settings: 0xFE, 0x0D, 0x0R, 0x0L, 0x80, 0x00, 0x00, where R - clockwise force,
L - counter-clockwise (0x0-0xF, 0xC = 100%).

Subject: HID: remove hid-ff

hid-ff.c now calls only pidff (generic driver), the special ones are now
in separate drivers. Invoke pidff on all non-special directly.

Subject: HID: convert to dev_* prints

Since we have a real device bound to a driver, we may use struct
device for printing. Use dev_* functions instead of printks in
4 drivers.

Subject: HID: fix a lockup regression when using force feedback on a PID
 device

Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

Subject: HID: remove warn() macro from usb hid drivers

USB should not be having it's own printk macros, so remove warn() and
use the system-wide standard of dev_warn() wherever possible.  In the
few places that will not work out, use a basic printk().

Subject: HID: Don't let Avermedia Radio FM800 be handled by usb hid drivers

Based on an original patch from Alexey Klimov <klimov.linux@gmail.com>,
against kernel version 2.6.27.

This device is already handled by radio-mr800 driver, and we therefore
want usbhid not to touch it.

Once kernel configuration has CONFIG_HID turned on, let also all the
specialized drivers for quirky devices to be built (unless CONFIG_EMBEDDED is
specified), as usually users don't care that much which driver
gives them the functionality, but when they want generic support, they
probably want to have support for all the quirky devices as well.

Move rtc_wake_setup() from drivers/acpi/glue.c into the RTC driver
in drivers/rtc/rtc-cmos.c.

This removes the ordering constraint between the module_init(acpi_rtc_init)
and the cmos_do_probe() code that depends on it.

Subject: hvc_console: Fix free_irq in spinlocked section

    commit 611e097d7707741a336a0677d9d69bec40f29f3d
    Author: Christian Borntraeger <borntraeger@de.ibm.com>
    hvc_console: rework setup to replace irq functions with callbacks
    introduced a spinlock recursion problem. The notifier_del is
    called with a lock held, and in turns calls free_irq which then
    complains when manipulating procfs. This fixes it by moving the
    call to the notifier to outside of the locked section.

Subject: powerpc/pci: Improve detection of unassigned bridge resources

When the powerpc PCI layer is not configured to re-assign everything,
it currently fails to detect that a PCI to PCI bridge has been left
unassigned by the firmware and tries to allocate resource for the
default window values in the bridge (0...X) (with the notable exception
of a hack we have in there that detects some Apple firmware unassigned
bridge resources).

This results in resource allocation failures, which are generally
fixed up later on but it causes scary warnings in the logs and we
have seen the fixup code fall over in some circumstances (a different
issue to fix as well).

This code improves that by providing a more complete & useful function
to intuit that a bridge was left unassigned by the firmware, and thus
force a full re-allocation by the PCI code without trying to allocate
the existing useless resources first.

The algorithm we use basically considers unassigned a window that
starts at 0 (PCI address) if the corresponding address space enable
bit is not set. In addition, for memory space, it considers such a
resource unassigned also if the host bridge isn't configured to
forward cycles to address 0 (ie, the resource basically overlaps
main memory).

This fixes a range of problems with things like Bare-Metal support
on pSeries machines, or attempt to use partial firmware PCI setup.

Subject: powerpc: Fix link errors on 32-bit machines using legacy DMA

The new merged DMA code will try to access isa_bridge_pcidev when
trying to DMA to/from legacy devices. This is however only defined
on 64-bit. Fixes this for now by adding the variable, even if it
stays NULL. In the long run, we'll make isa-bridge.c common to
32 and 64-bit.

Subject: powerpc: Fix 32-bit SMP boot on CHRP

prom_init was changed to take a new argument, the address
where the kernel is loaded, which is now used to copy the
SMP spin loop down before use.

However, only head_64.S was adapted to pass this new value,
not head_32.S, thus breaking SMP boot on 32-bit SMP CHRP
machines.

Subject: powerpc/chrp: Fix detection of Python PCI host bridge on IBM CHRPs

The detection of the IBM "Python" PCI host bridge on IBM CHRP
machines such as old RS6000 was broken when we changed
of_device_is_compatible() from strncasecmp to strcasecmp (dropped
the "n" variant) due to the way IBM encodes the chip version.

We fix that by instead doing a match on the model property like
we do for others bridges in that file. It should be good enough

Subject: powerpc: Fix CHRP PCI config access for indirect_pci

Recently, indirect_pci was changed to test if the bus number requested
is the one hanging straight off the PHB, then it substitutes the bus
number with another one contained in a new "self_busno" field of the
pci_controller structure.

However, this breaks CHRP which didn't initialize this new field, and
which relies on having the right bus number passed to the hardware.

This fixes it by initializing this variable properly for all CHRP bridges

Subject: NFS: Fix the resolution problem with nfs_inode_attrs_need_update()

It appears that 'jiffies' timestamps do not have high enough resolution for
nfs_inode_attrs_need_update(). One problem is that a GETATTR can be
launched within < 1 jiffy of the last operation that updated the attribute.
Another problem is that RPC calls can take < 1 jiffy to execute.

We can fix this by switching the variables to use a simple global counter
that gets incremented every time we start another GETATTR call.

Subject: NFS: Fix a resolution problem with nfs_inode->cache_change_attribute

The cache_change_attribute is used to decide whether or not a directory has
changed, in which case we may need to look it up again. Again, the use of
'jiffies' leads to an issue of resolution.

Once again, the fix is to change nfs_inode->cache_change_attribute, and
just make it a simple counter.

Subject: x86: register a platform RTC device if PNP doesn't describe it

Most if not all x86 platforms have an RTC device, but sometimes the RTC
is not exposed as a PNP0b00/PNP0b01/PNP0b02 device in PNPBIOS or ACPI:

    http://bugzilla.kernel.org/show_bug.cgi?id=11580
    https://bugzilla.redhat.com/show_bug.cgi?id=451188

It's best if we can discover the RTC via PNP because then we know
which flavor of device it is, where it lives, and which IRQ it uses.

But if we can't, we should register a platform device using the
compiled-in RTC_PORT/RTC_IRQ resource assumptions.

Subject: rtc-cmos: look for PNP RTC first, then for platform RTC

We shouldn't rely on "pnp_platform_devices" to tell us whether there
is a PNP RTC device.

I introduced "pnp_platform_devices", but I think it was a mistake.
All it tells us is whether we found any PNPBIOS or PNPACPI devices.
Many machines have some PNP devices, but do not describe the RTC
via PNP.  On those machines, we need to do the platform driver probe
to find the RTC.

We should just register the PNP driver and see whether it claims anything.
If we don't find a PNP RTC, fall back to the platform driver probe.

This (in conjunction with the arch/x86/kernel/rtc.c patch to add
a platform RTC device when PNP doesn't have one) should resolve
these issues:

Subject: iwlwifi: fix compilation warning when CONFIG_IWLWIFI_DEBUG is not
 set.

When CONFIG_IWLWIFI_DEBUG is not set and CONFIG_IWLWIFI is set,
we get this compilation warning:
/wireless-next-2.6/drivers/net/wireless/iwlwifi/iwl-agn-rs.c: In
function 'rs_free_sta':
/wireless-next-2.6/drivers/net/wireless/iwlwifi/iwl-agn-rs.c:2425:
warning: unused variable 'priv'

This patch fixes it by adding __maybe_unused attribute.

Subject: mac80211: fix debugfs lockup

When debugfs_create_dir fails, sta_info_debugfs_add_work will not
terminate because it will find the same station again and again.
This is possible whenever debugfs fails for whatever reason; one
reason is a race condition in mac80211, unfortunately we cannot
do much about it, so just document it, it just means some station
may be missing from debugfs.

Subject: mac80211: fix HT information element parsing

There's no checking that the HT IEs are of the right length
which can be used by an attacker to cause an out-of-bounds
access by sending a too short HT information/capability IE.
Fix it by simply pretending those IEs didn't exist when too
short.

in interrupt context in atomic_dec_and_lock().

Subject: ath9k/mac80211: disallow fragmentation in ath9k, report to userspace

As I've reported, ath9k currently fails utterly when fragmentation
is enabled. This makes ath9k "support" hardware fragmentation by
not supporting fragmentation at all to avoid the double-free issue.
The patch also changes mac80211 to report errors from the driver
operation to userspace.

That hack in ath9k should be removed once the rate control algorithm
it has is fixed, and we can at that time consider removing the hw
fragmentation support entirely since it's not used by any driver.

Subject: KVM: VMX: Rename misnamed msr bits

MSR_IA32_FEATURE_LOCKED is just a bit in fact, which shouldn't be prefixed with
MSR_.  So is MSR_IA32_FEATURE_VMXON_ENABLED.

Subject: KVM: x86: accessors for guest registers

As suggested by Avi, introduce accessors to read/write guest registers.
This simplifies the ->cache_regs/->decache_regs interface, and improves
register caching which is important for VMX, where the cost of
vmcs_read/vmcs_write is significant.

[avi: fix warnings]

Subject: KVM: Move KVM TRACE DEFINITIONS to common header

Move KVM trace definitions from x86 specific kvm headers to common kvm
headers to create a cross-architecture numbering scheme for trace
events. This means the kvmtrace_format userspace tool won't need to know
which architecture produced the log file being processed.

Subject: KVM: Introduce kvm_set_irq to inject interrupts in guests

Subject: KVM: Move NMI IRET fault processing to new vmx_complete_interrupts()

Currently most interrupt exit processing is handled on the entry path,
which is confusing.  Move the NMI IRET fault processing to a new function,
vmx_complete_interrupts(), which is called on the vmexit path.

Subject: KVM: VMX: Move nmi injection failure processing to vm exit path

Instead of processing nmi injection failure in the vm entry path, move
it to the vm exit path (vm_complete_interrupts()).  This separates nmi
injection from nmi post-processing, and moves the nmi state from the VT
state into vcpu state (new variable nmi_injected specifying an injection
in progress).

Subject: KVM: VMX: Fix pending exception processing

The vmx code assumes that IDT-Vectoring can only be set when an exception
is injected due to the exception in question.  That's not true, however:
if the exception is injected correctly, and later another exception occurs
but its delivery is blocked due to a fault, then we will incorrectly assume
the first exception was not delivered.

Fix by unconditionally dequeuing the pending exception, and requeuing it
(or the second exception) if we see it in the IDT-Vectoring field.

Subject: KVM: VMX: Move interrupt post-processing to vmx_complete_interrupts()

Instead of looking at failed injections in the vm entry path, move
processing to the exit path in vmx_complete_interrupts().  This simplifes
the logic and removes any state that is hidden in vmx registers.

Subject: KVM: VMX: Remove redundant check in handle_rmode_exception

Since checking for vcpu->arch.rmode.active is already done whenever we
call handle_rmode_exception(), checking it inside the function is redundant.

Subject: KVM: VMX: Reinject real mode exception

As we execute real mode guests in VM86 mode, exception have to be
reinjected appropriately when the guest triggered them. For this purpose
the patch adopts the real-mode injection pattern used in vmx_inject_irq
to vmx_queue_exception, additionally taking care that the IP is set
correctly for #BP exceptions. Furthermore it extends
handle_rmode_exception to reinject all those exceptions that can be
raised in real mode.

This fixes the execution of himem.exe from FreeDOS and also makes its
debug.com work properly.

Note that guest debugging in real mode is broken now. This has to be
fixed by the scheduled debugging infrastructure rework (will be done
once base patches for QEMU have been accepted).

Subject: KVM: kvmtrace: Remove use of bit fields in kvm trace structure

This patch fixes kvmtrace use on big endian systems. When using bit fields the
compiler will lay data out in the wrong order expected when laid down into a
file.
This fixes it by using one variable instead of using bit fields.

Subject: KVM: kvmtrace: replace get_cycles with ktime_get v3

The current kvmtrace code uses get_cycles() while the interpretation would be
easier using using nanoseconds. ktime_get() should give at least the same
accuracy as get_cycles on all architectures (even better on 32bit archs) but
at a better unit (e.g. comparable between hosts with different frequencies.

Subject: KVM: Ignore DEBUGCTL MSRs with no effect

Netware writes to DEBUGCTL and reads from the DEBUGCTL and LAST*IP MSRs
without further checks and is really confused to receive a #GP during that.
To make it happy we should just make them stubs, which is exactly what SVM
already does.

Writes to DEBUGCTL that are vendor-specific are resembled to behave as if the
virtual CPU does not know them.

Subject: KVM: ppc: Stop saving host TLB state

We're saving the host TLB state to memory on every exit, but never using it.
Originally I had thought that we'd want to restore host TLB for heavyweight
exits, but that could actually hurt when context switching to an unrelated host
process (i.e. not qemu).

Since this decreases the performance penalty of all exits, this patch improves
guest boot time by about 15%.

Subject: KVM: ppc: Write only modified shadow entries into the TLB on exit

Track which TLB entries need to be written, instead of overwriting everything
below the high water mark. Typically only a single guest TLB entry will be
modified in a single exit.

Guest boot time performance improvement: about 15%.

Subject: KVM: powerpc: Map guest userspace with TID=0 mappings

When we use TID=N userspace mappings, we must ensure that kernel mappings have
been destroyed when entering userspace. Using TID=1/TID=0 for kernel/user
mappings and running userspace with PID=0 means that userspace can't access the
kernel mappings, but the kernel can directly access userspace.

The net is that we don't need to flush the TLB on privilege switches, but we do
on guest context switches (which are far more infrequent). Guest boot time
performance improvement: about 30%.

Subject: KVM: irq ack notification

Based on a patch from: Ben-Ami Yassour <benami@il.ibm.com>
which was based on a patch from: Amit Shah <amit.shah@qumranet.com>

Notify IRQ acking on PIC/APIC emulation. The previous patch missed two things:

- Edge triggered interrupts on IOAPIC
- PIC reset with IRR/ISR set should be equivalent to ack (LAPIC probably
needs something similar).

Date: Sat, 26 Jul 2008 17:01:01 -0300
Subject: KVM: PIT: fix injection logic and count

The PIT injection logic is problematic under the following cases:

1) If there is a higher priority vector to be delivered by the time
kvm_pit_timer_intr_post is invoked ps->inject_pending won't be set.
This opens the possibility for missing many PIT event injections (say if
guest executes hlt at this point).

2) ps->inject_pending is racy with more than two vcpus. Since there's no locking
around read/dec of pt->pending, two vcpu's can inject two interrupts for a single
pt->pending count.

Fix 1 by using an irq ack notifier: only reinject when the previous irq
has been acked. Fix 2 with appropriate locking around manipulation of
pending count and irq_ack by the injection / ack paths.

current code will do just fine. So as a first step, factor out
code to pvclock.c.

Subject: x86: KVM guest: use paravirt function to calculate cpu khz

We're currently facing timing problems in guests that do
calibration under heavy load, and then the load vanishes.
This means we'll have a much lower lpj than we actually should,
and delays end up taking less time than they should, which is a
nasty bug.

Solution is to pass on the lpj value from host to guest, and have it
preset.

Subject: KVM: direct mmio pfn check

Userspace may specify memory slots that are backed by mmio pages rather than
normal RAM.  In some cases it is not enough to identify these mmio pages
by pfn_valid().  This patch adds checking the PageReserved as well.

Subject: KVM: pci device assignment

Based on a patch from: Amit Shah <amit.shah@qumranet.com>

This patch adds support for handling PCI devices that are assigned to
the guest.

The device to be assigned to the guest is registered in the host kernel
and interrupt delivery is handled.  If a device is already assigned, or
the device driver for it is still loaded on the host, the device
assignment is failed by conveying a -EBUSY reply to the userspace.

Devices that share their interrupt line are not supported at the moment.

By itself, this patch will not make devices work within the guest.
The VT-d extension is required to enable the device to perform DMA.
Another alternative is PVDMA.

Subject: KVM: Reduce kvm stack usage in kvm_arch_vm_ioctl()

On my machine with gcc 3.4, kvm uses ~2k of stack in a few
select functions.  This is mostly because gcc fails to
notice that the different case: statements could have their
stack usage combined.  It overflows very nicely if interrupts
happen during one of these large uses.

This patch uses two methods for reducing stack usage.
1. dynamically allocate large objects instead of putting
   on the stack.
2. Use a union{} member for all of the case variables. This
   tricks gcc into combining them all into a single stack
   allocation. (There's also a comment on this)

Subject: KVM: Reduce stack usage in kvm_pv_mmu_op()

We're in a hot path.  We can't use kmalloc() because
it might impact performance.  So, we just stick the buffer that
we need into the kvm_vcpu_arch structure.  This is used very
often, so it is not really a waste.

We also have to move the buffer structure's definition to the
arch-specific x86 kvm header.

Subject: KVM: fix i8259 reset irq acking

The irq ack during pic reset has three problems:

- Ignores slave/master PIC, using gsi 0-8 for both.
- Generates an ACK even if the APIC is in control.
- Depends upon IMR being clear, which is broken if the irq was masked
at the time it was generated.

The last one causes the BIOS to hang after the first reboot of
Windows installation, since PIT interrupts stop.

[avi: fix check whether pic interrupts are seen by cpu]

Spurious acks can be generated, for example if the PIC is being reset.
Handle those acks gracefully rather than flooding the log with warnings.

Subject: KVM: Device assignment: Check for privileges before assigning irq

Even though we don't share irqs at the moment, we should ensure
regular user processes don't try to allocate system resources.

We check for capability to access IO devices (CAP_SYS_RAWIO) before
we request_irq on behalf of the guest.

Noticed by Avi.

Subject: KVM: MMU: Add generic shadow walker

We currently walk the shadow page tables in two places: direct map (for
real mode and two dimensional paging) and paging mode shadow.  Since we
anticipate requiring a third walk (for invlpg), it makes sense to have
a generic facility for shadow walk.

This patch adds such a shadow walker, walks the page tables and calls a
method for every spte encountered.  The method can examine the spte,
modify it, or even instantiate it.  The walk can be aborted by returning
nonzero from the method.

Subject: KVM: MMU: Add locking around kvm_mmu_slot_remove_write_access()

It was generally safe due to slots_lock being held for write, but it wasn't
very nice.

Subject: KVM: MMU: Fix setting the accessed bit on non-speculative sptes

The accessed bit was accidentally turned on in a random flag word, rather
than, the spte itself, which was lucky, since it used the non-EPT compatible
PT_ACCESSED_MASK.

Fix by turning the bit on in the spte and changing it to use the portable
accessed mask.

EPT is 4 level by default in 32pae(48 bits), but the addr parameter
of kvm_shadow_walk->entry() only accept unsigned long as virtual
address, which is 32bit in 32pae. This result in SHADOW_PT_INDEX()
overflow when try to fetch level 4 index.

Fix it by extend kvm_shadow_walk->entry() to accept 64bit addr in

The patch adds in/out instructions to the x86 emulator.

The instruction was encountered while running the BIOS while using
the invalid guest state emulation patch.

Subject: KVM: x86: do not execute halted vcpus

Offline or uninitialized vcpu's can be executed if requested to perform
userspace work.

Follow Avi's suggestion to handle halted vcpu's in the main loop,
simplifying kvm_emulate_halt(). Introduce a new vcpu->requests bit to
indicate events that promote state from halted to running.

Also standardize vcpu wake sites.

Since "KVM: x86: do not execute halted vcpus", HLT by vcpu0 before system
reset by the IO thread will hang the guest.

Mark vcpu as runnable in such case.

Commit 1c0f4f5011829dac96347b5f84ba37c2252e1e08 left a useless access
of VM_ENTRY_INTR_INFO_FIELD in vmx_intr_assist behind. Clean this up.

Subject: KVM: x86 emulator: fix jmp r/m64 instruction

jmp r/m64 doesn't require the rex.w prefix to indicate the operand size
is 64 bits.  Set the Stack attribute (even though it doesn't involve the
stack, really) to indicate this.

Subject: KVM: x86 emulator: Add DstAcc operand type

Add DstAcc operand type. That means that there are 4 bits now for
DstMask.

"In the good old days cpus would have only one register that was able to
 fully participate in arithmetic operations, typically called A for
 Accumulator.  The x86 retains this tradition by having special, shorter
 encodings for the A register (like the cmp opcode), and even some
 instructions that only operate on A (like mul).

 SrcAcc and DstAcc would accommodate these instructions by decoding A
 into the corresponding 'struct operand'."

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

drivers/md/raid1.c: In function 'sync_request':
drivers/md/raid1.c:1759: error: implicit declaration of function 'msleep_interruptible'

Caused by commit 6caa3b0bbdb474647f6bdd8a958ffc46f78d8d58 ("md: Remove
unnecessary #includes, #defines, and function declarations").  I added
the following patch.

Subject: MIPS: PCI: Scan busses when they are registered

The patch below changes register_pci_controller() such that controllers
being added after pcibios_init() has run are be scanned immediately.

This is needed for example by the BCM47xx PCI controller, which is located
on the SSB bus, which is now initialized after the PCI subsystem.

From a9ff8f6462635c8d9f8d64b7b10ddcea8404d77b Mon Sep 17 00:00:00 2001
From: Marc Zyngier <maz@misterjones.org>
Date: Wed, 15 Oct 2008 12:54:05 +0100
Subject: [ARM] 5308/1: Fix Viper ISA IRQ handling

The ISA IRQ renumbering broke the Viper ISA code in interesting ways.
It originally assumed that ISA interrupt were numbered in the order that
is defined by the CPLD registers. Unfortunately, this is no longer the
case.

Furthermore, the viper_irq_handler() function being a chained IRQ
handler, it must ACK the interrupt by itself, or the handler will be
immediately reentered, with the expected damages.

This fix was made possible thanks to the help of David Raeman, who
provided debug information and tested each version of this patch.

From 62c476c7c7f25a5b245b9902a935636e6316e58c Mon Sep 17 00:00:00 2001
From: Ben-Ami Yassour <benami@il.ibm.com>
Date: Sun, 14 Sep 2008 03:48:28 +0300
Subject: KVM: Device Assignment with VT-d

Based on a patch by: Kay, Allen M <allen.m.kay@intel.com>

This patch enables PCI device assignment based on VT-d support.
When a device is assigned to the guest, the guest memory is pinned and
the mapping is updated in the VT-d IOMMU.

[Amit: Expose KVM_CAP_IOMMU so we can check if an IOMMU is present
and also control enable/disable from userspace]

Subject: KVM: Device Assignment: Free device structures if IRQ allocation
 fails

When an IRQ allocation fails, we free up the device structures and
disable the device so that we can unregister the device in the
userspace and not expose it to the guest at all.

Subject: KVM: opencode gfn_to_page in kvm_vm_fault

kvm_vm_fault is invoked with mmap_sem held in read mode. Since gfn_to_page
will be converted to get_user_pages_fast, which requires this lock NOT
to be held, switch to opencoded get_user_pages.

Subject: KVM: switch to get_user_pages_fast

Convert gfn_to_pfn to use get_user_pages_fast, which can do lockless
pagetable lookups on x86. Kernel compilation on 4-way guest is 3.7%
faster on VMX.

Subject: KVM: don't enter guest after SIPI was received by a CPU

The vcpu should process pending SIPI message before entering guest mode again.
kvm_arch_vcpu_runnable() returns true if the vcpu is in SIPI state, so
we can't call it here.

Subject: KVM: Don't destroy vcpu in case vcpu_setup fails

One of vcpu_setup responsibilities is to do mmu initialization.
However, in case we fail in kvm_arch_vcpu_reset, before we get the
chance to init mmu. OTOH, vcpu_destroy will attempt to destroy mmu,
triggering a bug. Keeping track of whether or not mmu is initialized
would unnecessarily complicate things. Rather, we just make return,
making sure any needed uninitialization is done before we return, in
case we fail.

Subject: KVM: ia64: add support for Tukwila processors

In Tukwila processor, VT-i has been enhanced in its
implementation, it is often called VT-i2 techonology.
With VTi-2 support, virtulization performance should be
improved. In this patch, we added the related stuff to
support kvm/ia64 for Tukwila processors.

Subject: KVM: MMU: do not write-protect large mappings

There is not much point in write protecting large mappings. This
can only happen when a page is shadowed during the window between
is_largepage_backed and mmu_lock acquision. Zap the entry instead, so
the next pagefault will find a shadowed page via is_largepage_backed and
fallback to 4k translations.

Simplifies out of sync shadow.

Subject: KVM: MMU: out of sync shadow core

Allow guest pagetables to go out of sync.  Instead of emulating write
accesses to guest pagetables, or unshadowing them, we un-write-protect
the page table and allow the guest to modify it at will.  We rely on
invlpg executions to synchronize individual ptes, and will synchronize
the entire pagetable on tlb flushes.

Subject: KVM: PIC: enhance IPI avoidance

The PIC code makes little effort to avoid kvm_vcpu_kick(), resulting in
unnecessary guest exits in some conditions.

For example, if the timer interrupt is routed through the IOAPIC, IRR
for IRQ 0 will get set but not cleared, since the APIC is handling the
acks.

This means that everytime an interrupt < 16 is triggered, the priority
logic will find IRQ0 pending and send an IPI to vcpu0 (in case IRQ0 is
not masked, which is Linux's case).

Introduce a new variable isr_ack to represent the IRQ's for which the
guest has been signalled / cleared the ISR. Use it to avoid more than
one IPI per trigger-ack cycle, in addition to the avoidance when ISR is
set in get_priority().

Subject: KVM: x86: Silence various LAPIC-related host kernel messages

KVM-x86 dumps a lot of debug messages that have no meaning for normal
operation:
 - INIT de-assertion is ignored
 - SIPIs are sent and received
 - APIC writes are unaligned or < 4 byte long
   (Windows Server 2003 triggers this on SMP)

Degrade them to true debug messages, keeping the host kernel log clean
for real problems.

Subject: x86: fix compat-vdso

Jeff Chua reported that this patch:

> -#define PTE_IDENT_ATTR  0x007          /* PRESENT+RW+USER */
> -#define PDE_IDENT_ATTR  0x067          /* PRESENT+RW+USER+DIRTY+ACCESSED */

> +#define PDE_IDENT_ATTR  0x063          /* PRESENT+RW+DIRTY+ACCESSED */

broke kernels with CONFIG_COMPAT_VDSO set with this init segfault:

init[1]: segfault at ffffe01c up b7f0dc28 sp bfc26628 error 5 in ld-2.7.90.so[b7f0b000+1c000]

Include USER bit in the PDE_IDENT_ATTR only, as the protection bits
are combined from the PDE and PTE entries. This will allow the high
mapped VDSO page in the case of CONFIG_COMPAT_VDSO to be user
readable.

Subject: xfs: fix remount rw with unrecognized options

When we skip unrecognized options in xfs_fs_remount we should just break
out of the switch and not return because otherwise we may skip clearing
the xfs-internal read-only flag.  This will only show up on some
operations like touch because most read-only checks are done by the VFS
which thinks this filesystem is r/w.  Eventually we should replace the
XFS read-only flag with a helper that always checks the VFS flag to make
sure they can never get out of sync.

Bug reported and fix verified by Marcel Beister on #xfs.
Bug fix verified by updated xfstests/189.

Subject: metronomefb: Fix warning when building 64bit

The metronome driver produces warnings when built on x86-64 as it assumes that
size_t is an int. Use %Zd instead.

Subject: tty: make sure that proc_clear_tty stores the cpu flags

proc_clear_tty() gets called with interrupts off (while holding the task list
lock) from sys_setid. This means that it needs the _irqsave version of the
locking primitives.

Subject: ieee1394: sbp2: stricter dma_sync

Two dma_sync_single_for_cpu() were called in the wrong place.
Luckily they were merely for DMA_TO_DEVICE, hence nobody noticed.

Also reorder the matching dma_sync_single_for_device() a little bit
so that they reside in the same functions as their counterparts.
This also avoids syncing the s/g table for requests which don't use it.

Subject: ieee1394: sbp2: enforce s/g segment size limit

1. We don't need to round the SBP-2 segment size limit down to a
   multiple of 4 kB (0xffff -> 0xf000).  It is only necessary to
   ensure quadlet alignment (0xffff -> 0xfffc).

2. Use dma_set_max_seg_size() to tell the DMA mapping infrastructure
   and the block IO layer about the restriction.  This way we can
   remove the size checks and segment splitting in the queuecommand
   path.

   This assumes that no other code in the ieee1394 stack uses
   dma_map_sg() with conflicting requirements.  It furthermore assumes
   that the controller device's platform actually allows us to set the
   segment size to our liking.  Assert the latter with a BUG_ON().

3. Also use blk_queue_max_segment_size() to tell the block IO layer
   about it.  It cannot know it because our scsi_add_host() does not
   point to the FireWire controller's device.

We can also uniformly use dma_map_sg() for the single segment case just
like for the multi segment case, to further simplify the code.

Also clean up how the page table is converted to big endian.

Thanks to Grant Grundler and FUJITA Tomonori for advice.

Subject: ieee1394: raw1394: replace BKL by local mutex, make ioctl() and
 mmap() thread-safe

This removes the last usage of the Big Kernel Lock from the ieee1394
stack, i.e. from raw1394's (unlocked_)ioctl and compat_ioctl.

The ioctl()s don't need to take the BKL, but they need to be serialized
per struct file *.  In particular, accesses to ->iso_state need to be
serial.  We simply use a blocking mutex for this purpose because
libraw1394 does not use O_NONBLOCK.  In practice, there is no lock
contention anyway because most if not all libraw1394 clients use a
libraw1394 handle only in a single thread.

mmap() also accesses ->iso_state.  Until now this was unprotected
against concurrent changes by ioctls.  Fix this bug while we are at it.

Subject: ieee1394: raw1394: narrow down the state_mutex protected region

Refactor the ioctl dispatcher in order to move a fraction of it out of
the section which is serialized by fi->state_mutex.  This is not so much
about performance but more about self-documentation:  The mutex_lock()/
mutex_unlock() calls are now closer to the data accesses which the mutex
protects, i.e. to the iso_state switch.

Subject: ieee1394: raw1394: make write() thread-safe

Application programs should use a libraw1394 handle only in a single
thread.  The raw1394 driver was apparently relying on this, because it
did nothing to protect its fi->state variable from corruption due to
concurrent accesses.

We now serialize the fi->state accesses.  This affects the write() path.
We re-use the state_mutex which was introduced to protect fi->iso_state
accesses in the ioctl() path.  These paths and accesses are independent
of each other, hence separate mutexes could be used.  But I don't see
much benefit in that.

Subject: ieee1394: dv1394, video1394: remove unnecessary expressions

init->channel and v.buffer are unsigned and tests for < 0 therefore
always false.  gcc knows this and eliminates the code, but anyway...

Subject: ieee1394: survive a few seconds connection loss

There are situations when nodes vanish from the bus and come back in
quickly thereafter:
  - When certain bus-powered hubs are plugged in,
  - when certain disk enclosures are switched from self-power to bus
    power or vice versa and break the daisy chain during the transition,
  - when the user plugs a cable out and quickly plugs it back in, e.g.
    to reorder a daisy chain (works on Mac OS X if done quickly enough),
  - when certain hubs temporarily malfunction during high bus traffic.

The ieee1394 driver's nodemgr already contained a function to set
vanished nodes aside into "limbo"; i.e. they wouldn't actually be
deleted right away.  (In fact, only unloading the driver or writing into
an obscure sysfs attribute would delete them eventually.)  If nodes
reappeared later, they would be resurrected out of limbo.

Moving nodes into and out of limbo was accompanied with calling the
.suspend() and .resume() driver methods of the drivers which were bound
to a respective node's unit directories.  Not only is this somewhat
strange due to the intended use of these driver methods for power
management, also the sbp2 driver in particular does not implement
.suspend() and .resume().  Hence sbp2 would be disconnected from devices
in situations as listed above.

We now:
  - leave drivers bound when nodes go into limbo,
  - call the drivers' .update() when nodes come out of limbo,
  - automatically delete in-limbo nodes 3 seconds after the last
    bus reset and bus rescan.
  - Because of the automatic removal, the now obsolete bus attribute
    /sys/bus/ieee1394/destroy_node is removed.

This especially lets sbp2 survive brief disconnections.  You can for
example yank a disk's cable and plug it back in while reading the
respective disk with dd, but dd will happily continue as if nothing
happened.

Content-Transfer-Encoding: 8bit

Share code between fw_send_request + wait_for_completion callers.

Addendum:
Removes an unnecessary struct and an ununsed retry loop.
Calls it fw_run_transaction() instead of fw_send_request_sync().

Subject: firewire: fw-sbp2: enforce s/g segment size limit

1. We don't need to round the SBP-2 segment size limit down to a
   multiple of 4 kB (0xffff -> 0xf000).  It is only necessary to
   ensure quadlet alignment (0xffff -> 0xfffc).

2. Use dma_set_max_seg_size() to tell the DMA mapping infrastructure
   and the block IO layer about the restriction.  This way we can
   remove the size checks and segment splitting in the queuecommand
   path.

   This assumes that no other code in the firewire stack uses
   dma_map_sg() with conflicting requirements.  It furthermore assumes
   that the controller device's platform actually allows us to set the
   segment size to our liking.  Assert the latter with a BUG_ON().

3. Also use blk_queue_max_segment_size() to tell the block IO layer
   about it.  It cannot know it because our scsi_add_host() does not
   point to the FireWire controller's device.

Thanks to Grant Grundler and FUJITA Tomonori for advice.

Subject: firewire: fw-sbp2: fix another small generation access bug

queuecommand() looked at the remote and local node IDs before it read
the bus generation.  The corresponding race with sbp2_reconnect updating
these data was probably impossible to happen though because the current
code blocks the SCSI layer during reconnection.  However, better safe
than sorry, especially if someone later improves the code to not block
the SCSI layer.

Subject: IPV6: Fix default gateway criteria wrt. HIGH/LOW preference radv
 option

Problem observed:
               In IPv6, in the presence of multiple routers candidates to
               default gateway in one segment, each sending a different
               value of preference, the Linux hosts connected to the
               segment weren't selecting the right one in all the
               combinations possible of LOW/MEDIUM/HIGH preference.

This patch changes two files:
include/linux/icmpv6.h
               Get the "router_pref" bitfield in the right place
               (as RFC4191 says), named the bit left with this fix as
               "home_agent" (RFC3775 say that's his function)

net/ipv6/ndisc.c
               Corrects the binary logic behind the updating of the
               router preference in the flags of the routing table

Result:
               With this two fixes applied, the default route used by
               the system was to consistent with the rules mentioned
               in RFC4191 in case of changes in the value of preference
               in router advertisements

Subject: HID: fix default building of HID-quirk drivers

Commit 9be7bbd54df3c9c393ccd19acc49f90c517d1291
(HID: build drivers for all quirky devices by default)
made a wrong assumption about select/depends interaction in Kconfig,
resulting in possibility of link failure with certain configuration
options.

Fix this by explicitly having all the quirk-drivers depend on
USB_HID, default to y and make the possibility to alter the
settings dependent on EBMEDDED.

Subject: cpufreq: remove policy->governor setting in drivers initialization

As policy->governor is already set to CPUFREQ_DEFAULT_GOVERNOR in the
(always built-in) cpufreq core, we do not need to set it in the drivers.
This fixes the sparc64 allmodconfig build failure.

Also, remove a totally useles setting of ->policy in cpufreq-pxa3xx.c.

Subject: agp: Fix stolen memory counting on G4X.

On the GM45, the amount of stolen memory mapped to the GTT was underestimated,
even though we had 508KB more available since the GTT doesn't take from
stolen memory. On the non-GM45 G4X, we overestimated how much stolen was
mapped to the GTT by 4KB, resulting in GPU page faults when that page was
accessed.

This update requires a corresponding update to xf86-video-intel to work
correctly.

Subject: agp/intel: Reduce extraneous PCI posting reads during init

Instead of doing a posting read after each GTT entry update, do a single one
at the end of the writes. This should reduce boot time a tiny amount by
avoiding a lot of extra uncached reads.

Subject: [netdrvr] myri10ge, ixgbe: remove broken select INTEL_IOATDMA

We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE or IXGBE
is enabled since the former is not available on all architectures.

Just use a Kconfig bool {IXGBE,MYRI10GE}_DCA set to =y when DCA
support can actually be built.

[myri10ge portion written and signed-off-by] Brice Goglin <brice@myri.com>

Subject: lmc: copy_*_user under spinlock

Not sure anyone uses this driver any more, maybe we should just drop it ?
Code is still foul but at least a fraction less broken.

For whatever value of 'OK' can be applied to the use of token ring. Seems
the 32bit to 64bit cleanups missed re-enabling the pcmcia driver

Closes #7133 and also reviewed the code in question

From 17bc6c30cf6bfffd816bdc53682dd46fc34a2cf4 Mon Sep 17 00:00:00 2001
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
Date: Thu, 16 Oct 2008 10:09:17 -0400
Subject: vfs: Add no_nrwrite_index_update writeback control flag

If no_nrwrite_index_update is set we don't update nr_to_write and
address space writeback_index in write_cache_pages.  This change
enables a file system to skip these updates in write_cache_pages and do
them in the writepages() callback.  This patch will be followed by an
ext4 patch that make use of these new flags.

Subject: ext4: Fix file fragmentation during large file write.

The range_cyclic writeback mode uses the address_space writeback_index
as the start index for writeback.  With delayed allocation we were
updating writeback_index wrongly resulting in highly fragmented file.
This patch reduces the number of extents reduced from 4000 to 27 for a
3GB file.

Subject: remove CONFIG_KMOD from drivers

Straight forward conversions to CONFIG_MODULE; many drivers
include <linux/kmod.h> conditionally and then don't have any
other conditional code so remove it from those.

Subject: remove CONFIG_KMOD from fs

Just always compile the code when the kernel is modular.
Convert load_nls to use try_then_request_module to tidy
up the code.

From ae87221d3ce49d9de1e43756da834fd0bf05a2ad Mon Sep 17 00:00:00 2001

Subject: sysfs: crash debugging

Print the name of the last-accessed sysfs file when we oops, to help track
down oopses which occur in sysfs store/read handlers.  Because these oopses
tend to not leave any trace of the offending code in the stack traces.

Subject: usb gadget: link fixes for serial gadget

Change how the serial gadget driver builds:  don't use
separate compilation, since it works poorly when key parts
are library code (with init sections etc).  Instead be as
close as we can to "gcc --combine ...".

Change how the Ethernet/RNDIS gadget driver builds:  don't
use separate compilation, since it works poorly when key
parts are library code (with init sections etc).  Instead
be as close as we can to "gcc --combine ...".

This is a bit more complicated than most of the others
because it had to resolve a few symbol collisions.

From 346e15beb5343c2eb8216d820f2ed8f150822b08 Mon Sep 17 00:00:00 2001
From: Jason Baron <jbaron@redhat.com>
Date: Tue, 12 Aug 2008 16:46:19 -0400
Subject: driver core: basic infrastructure for per-module dynamic debug
 messages

Base infrastructure to enable per-module debug messages.

I've introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes
control of debugging statements on a per-module basis in one /proc file,
currently, <debugfs>/dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG,
is not set, debugging statements can still be enabled as before, often by
defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no
affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set.

The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That
is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls
can be dynamically enabled/disabled on a per-module basis.

Future plans include extending this functionality to subsystems, that define
their own debug levels and flags.

Usage:

Dynamic debugging is controlled by the debugfs file,
<debugfs>/dynamic_printk/modules. This file contains a list of the modules that
can be enabled. The format of the file is as follows:

	<module_name> <enabled=0/1>
		.
		.
		.

	<module_name> : Name of the module in which the debug call resides
	<enabled=0/1> : whether the messages are enabled or not

For example:

	snd_hda_intel enabled=0
	fixup enabled=1
	driver enabled=0

Enable a module:

	$echo "set enabled=1 <module_name>" > dynamic_printk/modules

Disable a module:

	$echo "set enabled=0 <module_name>" > dynamic_printk/modules

Enable all modules:

	$echo "set enabled=1 all" > dynamic_printk/modules

Disable all modules:

	$echo "set enabled=0 all" > dynamic_printk/modules

Finally, passing "dynamic_printk" at the command line enables
debugging for all modules. This mode can be turned off via the above
disable command.

[gkh: minor cleanups and tweaks to make the build work quietly]

+
+	  Compiles debug level messages into the kernel, which would not
+	  otherwise be available at runtime. These messages can then be
+	  enabled/disabled on a per module basis. This mechanism implicitly
+	  enables all pr_debug() and dev_dbg() calls. The impact of this
+	  compile option is a larger kernel text size of about 2%.
+
+	  Usage:
+
+	  Dynamic debugging is controlled by the debugfs file,
+	  dynamic_printk/modules. This file contains a list of the modules that
+	  can be enabled. The format of the file is the module name, followed
+	  by a set of flags that can be enabled. The first flag is always the
+	  'enabled' flag. For example:
+
+		<module_name> <enabled=0/1>
+				.
+				.
+				.
+
+	  <module_name> : Name of the module in which the debug call resides
+	  <enabled=0/1> : whether the messages are enabled or not
+
+	  From a live system:
+
+		snd_hda_intel enabled=0
+		fixup enabled=0
+		driver enabled=0
+
+	  Enable a module:
+
+	  	$echo "set enabled=1 <module_name>" > dynamic_printk/modules
+
+	  Disable a module:
+
+	  	$echo "set enabled=0 <module_name>" > dynamic_printk/modules
+
+	  Enable all modules:
+
+		$echo "set enabled=1 all" > dynamic_printk/modules
+
+	  Disable all modules:
+
+		$echo "set enabled=0 all" > dynamic_printk/modules
+
+	  Finally, passing "dynamic_printk" at the command line enables
+	  debugging for all modules. This mode can be turned off via the above
+	  disable command.

Subject: sysfs: Support sysfs_notify from atomic context with new
 sysfs_notify_dirent

Support sysfs_notify from atomic context with new sysfs_notify_dirent

sysfs_notify currently takes sysfs_mutex.
This means that it cannot be called in atomic context.
sysfs_mutex  is sometimes held over a malloc (sysfs_rename_dir)
so it can block on low memory.

In md I want to be able to notify on a sysfs attribute from
atomic context, and I don't want to block on low memory because I
could be in the writeout path for freeing memory.

So:
 - export the "sysfs_dirent" structure along with sysfs_get, sysfs_put
   and sysfs_get_dirent so I can get the sysfs_dirent that I want to
   notify on and hold it in an md structure.
 - split sysfs_notify_dirent out of sysfs_notify so the sysfs_dirent
   can be notified on with no blocking (just a spinlock).

Subject: device model: Do a quickcheck for driver binding before doing an
 expensive check

This patch adds a quick check for the driver<->device match before
taking the locks and doin gthe expensive checks. Taking the lock hurts
in asynchronous boot context where the device lock gets hit; one of the
init functions takes the lock and goes to do an expensive hardware init;
the other init functions walk the same PCI list and get stuck on the
lock as a result.

For the common case, we can know there's no chance whatsoever of a match
if the device isn't in the drivers ID table... so this patch does that
check as a best-effort-avoid-the-lock approach.

Bootcharts for before and after can be seen at
http://www.fenrus.org/before.svg
http://www.fenrus.org/after.svg

Note the long time "agp_ali_init" takes in the first graph; my laptop
doesn't even have an ALI chip in it!  (the bootgraphs look a bit
dissimilar, but that's the point, the first one has a bunch of arbitrary
delays in it that cause it to look very different)

This reduces my kernel boot time by about 20%

Yes, it is a real bug by the looks. bin.c takes bb->mutex under mmap_sem
when it is mmapped, and then does its copy_*_user under bb->mutex too.

Here is a basic fix for the sysfs lor.

Subject: debug: Introduce a dev_WARN() function

in the line of dev_printk(), this patch introduces a dev_WARN() function,
that takes a struct device and then a printk format/args set of arguments.
Unlike dev_printk(), the effect is that of WARN() in that a full warning
message (including filename/line, module list, versions and a backtrace)
is printed in addition to the device name and the arguments.

Subject: debug: use dev_WARN() rather than WARN_ON() in device_pm_add()

device_pm_add() has a WARN_ON that is showing relatively high on
kerneloops.org, but unfortunately the WARN_ON is less than useful
in that it doesn't print any information about what device is causing
the issue.

This patch fixes this by turning the WARN_ON() into the newly
introduces dev_WARN() which will print information about the
device in question.

Subject: usb: turn dev_warn+WARN_ON combos into dev_WARN

dev_WARN is both compacter and gives better debug information
than just a WARN_ON, since people and tools will copy the device
information message together with the WARN_ON in bug reports.

Subject: sysfs: use ilookup5() instead of ilookup5_nowait()

As inode creation is protected by sysfs_mutex, ilookup5_nowait()
always either fails to find at all or finds one which is fully
initialized, so using ilookup5_nowait() or ilookup5() doesn't make any
difference.  Switch to ilookup5() as it's planned to be removed.  This
change also makes lookup return value handling a bit simpler.

This change was suggested by Al Viro.

Subject: kobject: Fix kobject_rename and !CONFIG_SYSFS

When looking at kobject_rename I found two bugs with
that exist when sysfs support is disabled in the kernel.

kobject_rename does not change the name on the kobject when
sysfs support is not compiled in.

kobject_rename without locking attempts to check the
validity of a rename operation, which the kobject layer
simply does not have the infrastructure to do.

This patch documents the previously unstated requirement of
kobject_rename that is the responsibility of the caller to
provide mutual exclusion and to be certain that the new_name
for the kobject is valid.

This patch modifies sysfs_rename_dir in !CONFIG_SYSFS case
to call kobject_set_name to actually change the kobject_name.

This patch removes the bogus and misleading check in kobject_rename
that attempts to see if a rename is valid.  The check is bogus
because we do not have the proper locking.  The check is misleading
because it looks like we can and do perform checking at the kobject
level that we don't.

Subject: Driver core: add bus_sort_breadthfirst() function

The PCI core wants to reorder the devices in the bus list.  So move this
functionality out of the pci core and into the driver core so that
anyone else can also do this if needed.  This also lets us change how
struct device is attached to drivers in the future without messing with
the PCI core.

Subject: UIO: Change driver name of uio_pdrv

The generic UIO platform device driver should be given a unique driver ID and
not just "uio". This is especially important since we now have a similar driver
named uio_pdrv_genirq. Currently, there's no user of this driver in the
mainline kernel.

Subject: UIO: add automata sercos3 pci card support

Here is a new version of the patch to support the Automata Sercos III
PCI card driver. I now check that the IRQ is enabled before accepting
the interrupt.

I still use a logical OR to store the enabled interrupts and I've
added a second use of a logical OR when restoring the enabled
interrupts. I added an explanation of why I do this in comments at the
top of the source file.

Since I use a logical OR, I also removed the extra checks if the
Interrupt Enable Register and ier0_cache are 0.

+
+   Copyright (C) 2008 Linutronix GmbH
+     Author: John Ogness <john.ogness@linutronix.de>
+
+   This is a straight-forward UIO driver, where interrupts are disabled
+   by the interrupt handler and re-enabled via a write to the UIO device
+   by the userspace-part.
+
+   The only part that may seem odd is the use of a logical OR when
+   storing and restoring enabled interrupts. This is done because the
+   userspace-part could directly modify the Interrupt Enable Register
+   at any time. To reduce possible conflicts, the kernel driver uses
+   a logical OR to make more controlled changes (rather than blindly
+   overwriting previous values).
+
+   Race conditions exist if the userspace-part directly modifies the
+   Interrupt Enable Register while in operation. The consequences are
+   that certain interrupts would fail to be enabled or disabled. For
+   this reason, the userspace-part should only directly modify the
+   Interrupt Enable Register at the beginning (to get things going).
+   The userspace-part can safely disable interrupts at any time using
+   a write to the UIO device.

Subject: UIO: Fix mapping of logical and virtual memory

mmap() doesn't work as expected for UIO_MEM_LOGICAL or UIO_MEM_VIRTUAL
mappings. The offset into the memory needs to be added, otherwise
uio_vma_fault always returns the first page only. Note that for UIO
userspace calls mmap() with offset = N * getpagesize() to access
mapping N. This must be compensated when calculating the offset. A
comment was added to explain this since it is not obvious.

+1: A GUIDE TO THE KERNEL DEVELOPMENT PROCESS
+
+The purpose of this document is to help developers (and their managers)
+work with the development community with a minimum of frustration.  It is
+an attempt to document how this community works in a way which is
+accessible to those who are not intimately familiar with Linux kernel
+development (or, indeed, free software development in general).  While
+there is some technical material here, this is very much a process-oriented
+discussion which does not require a deep knowledge of kernel programming to
+understand.
+
+
+1.1: EXECUTIVE SUMMARY
+
+The rest of this section covers the scope of the kernel development process
+and the kinds of frustrations that developers and their employers can
+encounter there.  There are a great many reasons why kernel code should be
+merged into the official ("mainline") kernel, including automatic
+availability to users, community support in many forms, and the ability to
+influence the direction of kernel development.  Code contributed to the
+Linux kernel must be made available under a GPL-compatible license.
+
+Section 2 introduces the development process, the kernel release cycle, and
+the mechanics of the merge window.  The various phases in the patch
+development, review, and merging cycle are covered.  There is some
+discussion of tools and mailing lists.  Developers wanting to get started
+with kernel development are encouraged to track down and fix bugs as an
+initial exercise.
+
+Section 3 covers early-stage project planning, with an emphasis on
+involving the development community as soon as possible.
+
+Section 4 is about the coding process; several pitfalls which have been
+encountered by other developers are discussed.  Some requirements for
+patches are covered, and there is an introduction to some of the tools
+which can help to ensure that kernel patches are correct.
+
+Section 5 talks about the process of posting patches for review.  To be
+taken seriously by the development community, patches must be properly
+formatted and described, and they must be sent to the right place.
+Following the advice in this section should help to ensure the best
+possible reception for your work.
+
+Section 6 covers what happens after posting patches; the job is far from
+done at that point.  Working with reviewers is a crucial part of the
+development process; this section offers a number of tips on how to avoid
+problems at this important stage.  Developers are cautioned against
+assuming that the job is done when a patch is merged into the mainline.
+
+Section 7 introduces a couple of "advanced" topics: managing patches with
+git and reviewing patches posted by others.
+
+Section 8 concludes the document with pointers to sources for more
+information on kernel development.
+
+
+1.2: WHAT THIS DOCUMENT IS ABOUT
+
+The Linux kernel, at over 6 million lines of code and well over 1000 active
+contributors, is one of the largest and most active free software projects
+in existence.  Since its humble beginning in 1991, this kernel has evolved
+into a best-of-breed operating system component which runs on pocket-sized
+digital music players, desktop PCs, the largest supercomputers in
+existence, and all types of systems in between.  It is a robust, efficient,
+and scalable solution for almost any situation.
+
+With the growth of Linux has come an increase in the number of developers
+(and companies) wishing to participate in its development.  Hardware
+vendors want to ensure that Linux supports their products well, making
+those products attractive to Linux users.  Embedded systems vendors, who
+use Linux as a component in an integrated product, want Linux to be as
+capable and well-suited to the task at hand as possible.  Distributors and
+other software vendors who base their products on Linux have a clear
+interest in the capabilities, performance, and reliability of the Linux
+kernel.  And end users, too, will often wish to change Linux to make it
+better suit their needs.
+
+One of the most compelling features of Linux is that it is accessible to
+these developers; anybody with the requisite skills can improve Linux and
+influence the direction of its development.  Proprietary products cannot
+offer this kind of openness, which is a characteristic of the free software
+process.  But, if anything, the kernel is even more open than most other
+free software projects.  A typical three-month kernel development cycle can
+involve over 1000 developers working for more than 100 different companies
+(or for no company at all).
+
+Working with the kernel development community is not especially hard.  But,
+that notwithstanding, many potential contributors have experienced
+difficulties when trying to do kernel work.  The kernel community has
+evolved its own distinct ways of operating which allow it to function
+smoothly (and produce a high-quality product) in an environment where
+thousands of lines of code are being changed every day.  So it is not
+surprising that Linux kernel development process differs greatly from
+proprietary development methods.
+
+The kernel's development process may come across as strange and
+intimidating to new developers, but there are good reasons and solid
+experience behind it.  A developer who does not understand the kernel
+community's ways (or, worse, who tries to flout or circumvent them) will
+have a frustrating experience in store.  The development community, while
+being helpful to those who are trying to learn, has little time for those
+who will not listen or who do not care about the development process.
+
+It is hoped that those who read this document will be able to avoid that
+frustrating experience.  There is a lot of material here, but the effort
+involved in reading it will be repaid in short order.  The development
+community is always in need of developers who will help to make the kernel
+better; the following text should help you - or those who work for you -
+join our community.

+
+
+1.4: THE IMPORTANCE OF GETTING CODE INTO THE MAINLINE
+
+Some companies and developers occasionally wonder why they should bother
+learning how to work with the kernel community and get their code into the
+mainline kernel (the "mainline" being the kernel maintained by Linus
+Torvalds and used as a base by Linux distributors).  In the short term,
+contributing code can look like an avoidable expense; it seems easier to
+just keep the code separate and support users directly.  The truth of the
+matter is that keeping code separate ("out of tree") is a false economy.
+
+As a way of illustrating the costs of out-of-tree code, here are a few
+relevant aspects of the kernel development process; most of these will be
+discussed in greater detail later in this document.  Consider:
+
+- Code which has been merged into the mainline kernel is available to all
+  Linux users.  It will automatically be present on all distributions which
+  enable it.  There is no need for driver disks, downloads, or the hassles
+  of supporting multiple versions of multiple distributions; it all just
+  works, for the developer and for the user.  Incorporation into the
+  mainline solves a large number of distribution and support problems.
+
+- While kernel developers strive to maintain a stable interface to user
+  space, the internal kernel API is in constant flux.  The lack of a stable
+  internal interface is a deliberate design decision; it allows fundamental
+  improvements to be made at any time and results in higher-quality code.
+  But one result of that policy is that any out-of-tree code requires
+  constant upkeep if it is to work with new kernels.  Maintaining
+  out-of-tree code requires significant amounts of work just to keep that
+  code working.
+
+  Code which is in the mainline, instead, does not require this work as the
+  result of a simple rule requiring any developer who makes an API change
+  to also fix any code that breaks as the result of that change.  So code
+  which has been merged into the mainline has significantly lower
+  maintenance costs.
+
+- Beyond that, code which is in the kernel will often be improved by other
+  developers.  Surprising results can come from empowering your user
+  community and customers to improve your product.
+
+- Kernel code is subjected to review, both before and after merging into
+  the mainline.  No matter how strong the original developer's skills are,
+  this review process invariably finds ways in which the code can be
+  improved.  Often review finds severe bugs and security problems.  This is
+  especially true for code which has been developed in a closed
+  environment; such code benefits strongly from review by outside
+  developers.  Out-of-tree code is lower-quality code.
+
+- Participation in the development process is your way to influence the
+  direction of kernel development.  Users who complain from the sidelines
+  are heard, but active developers have a stronger voice - and the ability
+  to implement changes which make the kernel work better for their needs.
+
+- When code is maintained separately, the possibility that a third party
+  will contribute a different implementation of a similar feature always
+  exists.  Should that happen, getting your code merged will become much
+  harder - to the point of impossibility.  Then you will be faced with the
+  unpleasant alternatives of either (1) maintaining a nonstandard feature
+  out of tree indefinitely, or (2) abandoning your code and migrating your
+  users over to the in-tree version.
+
+- Contribution of code is the fundamental action which makes the whole
+  process work.  By contributing your code you can add new functionality to
+  the kernel and provide capabilities and examples which are of use to
+  other kernel developers.  If you have developed code for Linux (or are
+  thinking about doing so), you clearly have an interest in the continued
+  success of this platform; contributing code is one of the best ways to
+  help ensure that success.
+
+All of the reasoning above applies to any out-of-tree kernel code,
+including code which is distributed in proprietary, binary-only form.
+There are, however, additional factors which should be taken into account
+before considering any sort of binary-only kernel code distribution.  These
+include:
+
+- The legal issues around the distribution of proprietary kernel modules
+  are cloudy at best; quite a few kernel copyright holders believe that
+  most binary-only modules are derived products of the kernel and that, as
+  a result, their distribution is a violation of the GNU General Public
+  license (about which more will be said below).  Your author is not a
+  lawyer, and nothing in this document can possibly be considered to be
+  legal advice.  The true legal status of closed-source modules can only be
+  determined by the courts.  But the uncertainty which haunts those modules
+  is there regardless.
+
+- Binary modules greatly increase the difficulty of debugging kernel
+  problems, to the point that most kernel developers will not even try.  So
+  the distribution of binary-only modules will make it harder for your
+  users to get support from the community.
+
+- Support is also harder for distributors of binary-only modules, who must
+  provide a version of the module for every distribution and every kernel
+  version they wish to support.  Dozens of builds of a single module can
+  be required to provide reasonably comprehensive coverage, and your users
+  will have to upgrade your module separately every time they upgrade their
+  kernel.
+
+- Everything that was said above about code review applies doubly to
+  closed-source code.  Since this code is not available at all, it cannot
+  have been reviewed by the community and will, beyond doubt, have serious
+  problems. 
+
+Makers of embedded systems, in particular, may be tempted to disregard much
+of what has been said in this section in the belief that they are shipping
+a self-contained product which uses a frozen kernel version and requires no
+more development after its release.  This argument misses the value of
+widespread code review and the value of allowing your users to add
+capabilities to your product.  But these products, too, have a limited
+commercial life, after which a new version must be released.  At that
+point, vendors whose code is in the mainline and well maintained will be
+much better positioned to get the new product ready for market quickly.
+
+
+1.5: LICENSING
+
+Code is contributed to the Linux kernel under a number of licenses, but all
+code must be compatible with version 2 of the GNU General Public License
+(GPLv2), which is the license covering the kernel distribution as a whole.
+In practice, that means that all code contributions are covered either by
+GPLv2 (with, optionally, language allowing distribution under later
+versions of the GPL) or the three-clause BSD license.  Any contributions
+which are not covered by a compatible license will not be accepted into the
+kernel.
+
+Copyright assignments are not required (or requested) for code contributed
+to the kernel.  All code merged into the mainline kernel retains its
+original ownership; as a result, the kernel now has thousands of owners.
+
+One implication of this ownership structure is that any attempt to change
+the licensing of the kernel is doomed to almost certain failure.  There are
+few practical scenarios where the agreement of all copyright holders could
+be obtained (or their code removed from the kernel).  So, in particular,
+there is no prospect of a migration to version 3 of the GPL in the
+foreseeable future.
+
+It is imperative that all code contributed to the kernel be legitimately
+free software.  For that reason, code from anonymous (or pseudonymous)
+contributors will not be accepted.  All contributors are required to "sign
+off" on their code, stating that the code can be distributed with the
+kernel under the GPL.  Code which has not been licensed as free software by
+its owner, or which risks creating copyright-related problems for the
+kernel (such as code which derives from reverse-engineering efforts lacking
+proper safeguards) cannot be contributed.
+
+Questions about copyright-related issues are common on Linux development
+mailing lists.  Such questions will normally receive no shortage of
+answers, but one should bear in mind that the people answering those
+questions are not lawyers and cannot provide legal advice.  If you have
+legal questions relating to Linux source code, there is no substitute for
+talking with a lawyer who understands this field.  Relying on answers
+obtained on technical mailing lists is a risky affair.

+2: HOW THE DEVELOPMENT PROCESS WORKS
+
+Linux kernel development in the early 1990's was a pretty loose affair,
+with relatively small numbers of users and developers involved.  With a
+user base in the millions and with some 2,000 developers involved over the
+course of one year, the kernel has since had to evolve a number of
+processes to keep development happening smoothly.  A solid understanding of
+how the process works is required in order to be an effective part of it.
+
+
+2.1: THE BIG PICTURE
+
+The kernel developers use a loosely time-based release process, with a new
+major kernel release happening every two or three months.  The recent
+release history looks like this:
+
+	2.6.26	July 13, 2008
+	2.6.25	April 16, 2008
+	2.6.24	January 24, 2008
+	2.6.23	October 9, 2007
+	2.6.22	July 8, 2007
+	2.6.21	April 25, 2007
+	2.6.20	February 4, 2007
+
+Every 2.6.x release is a major kernel release with new features, internal
+API changes, and more.  A typical 2.6 release can contain over 10,000
+changesets with changes to several hundred thousand lines of code.  2.6 is
+thus the leading edge of Linux kernel development; the kernel uses a
+rolling development model which is continually integrating major changes.
+
+A relatively straightforward discipline is followed with regard to the
+merging of patches for each release.  At the beginning of each development
+cycle, the "merge window" is said to be open.  At that time, code which is
+deemed to be sufficiently stable (and which is accepted by the development
+community) is merged into the mainline kernel.  The bulk of changes for a
+new development cycle (and all of the major changes) will be merged during
+this time, at a rate approaching 1,000 changes ("patches," or "changesets")
+per day.
+
+(As an aside, it is worth noting that the changes integrated during the
+merge window do not come out of thin air; they have been collected, tested,
+and staged ahead of time.  How that process works will be described in
+detail later on).
+
+The merge window lasts for two weeks.  At the end of this time, Linus
+Torvalds will declare that the window is closed and release the first of
+the "rc" kernels.  For the kernel which is destined to be 2.6.26, for
+example, the release which happens at the end of the merge window will be
+called 2.6.26-rc1.  The -rc1 release is the signal that the time to merge
+new features has passed, and that the time to stabilize the next kernel has
+begun.
+
+Over the next six to ten weeks, only patches which fix problems should be
+submitted to the mainline.  On occasion a more significant change will be
+allowed, but such occasions are rare; developers who try to merge new
+features outside of the merge window tend to get an unfriendly reception.
+As a general rule, if you miss the merge window for a given feature, the
+best thing to do is to wait for the next development cycle.  (An occasional
+exception is made for drivers for previously-unsupported hardware; if they
+touch no in-tree code, they cannot cause regressions and should be safe to
+add at any time).
+
+As fixes make their way into the mainline, the patch rate will slow over
+time.  Linus releases new -rc kernels about once a week; a normal series
+will get up to somewhere between -rc6 and -rc9 before the kernel is
+considered to be sufficiently stable and the final 2.6.x release is made.
+At that point the whole process starts over again.
+
+As an example, here is how the 2.6.25 development cycle went (all dates in
+2008): 
+
+	January 24	2.6.24 stable release
+	February 10	2.6.25-rc1, merge window closes
+	February 15	2.6.25-rc2
+	February 24	2.6.25-rc3
+	March 4	 	2.6.25-rc4
+	March 9		2.6.25-rc5
+	March 16	2.6.25-rc6
+	March 25	2.6.25-rc7
+	April 1		2.6.25-rc8
+	April 11	2.6.25-rc9
+	April 16	2.6.25 stable release
+
+How do the developers decide when to close the development cycle and create
+the stable release?  The most significant metric used is the list of
+regressions from previous releases.  No bugs are welcome, but those which
+break systems which worked in the past are considered to be especially
+serious.  For this reason, patches which cause regressions are looked upon
+unfavorably and are quite likely to be reverted during the stabilization
+period. 
+
+The developers' goal is to fix all known regressions before the stable
+release is made.  In the real world, this kind of perfection is hard to
+achieve; there are just too many variables in a project of this size.
+There comes a point where delaying the final release just makes the problem
+worse; the pile of changes waiting for the next merge window will grow
+larger, creating even more regressions the next time around.  So most 2.6.x
+kernels go out with a handful of known regressions though, hopefully, none
+of them are serious.
+
+Once a stable release is made, its ongoing maintenance is passed off to the
+"stable team," currently comprised of Greg Kroah-Hartman and Chris Wright.
+The stable team will release occasional updates to the stable release using
+the 2.6.x.y numbering scheme.  To be considered for an update release, a
+patch must (1) fix a significant bug, and (2) already be merged into the
+mainline for the next development kernel.  Continuing our 2.6.25 example,
+the history (as of this writing) is:
+
+	May 1		2.6.25.1
+	May 6		2.6.25.2 
+	May 9		2.6.25.3 
+	May 15		2.6.25.4
+	June 7		2.6.25.5
+	June 9		2.6.25.6
+	June 16		2.6.25.7
+	June 21		2.6.25.8
+	June 24		2.6.25.9
+
+Stable updates for a given kernel are made for approximately six months;
+after that, the maintenance of stable releases is solely the responsibility
+of the distributors which have shipped that particular kernel.
+
+
+2.2: THE LIFECYCLE OF A PATCH
+
+Patches do not go directly from the developer's keyboard into the mainline
+kernel.  There is, instead, a somewhat involved (if somewhat informal)
+process designed to ensure that each patch is reviewed for quality and that
+each patch implements a change which is desirable to have in the mainline.
+This process can happen quickly for minor fixes, or, in the case of large
+and controversial changes, go on for years.  Much developer frustration
+comes from a lack of understanding of this process or from attempts to
+circumvent it.  
+
+In the hopes of reducing that frustration, this document will describe how
+a patch gets into the kernel.  What follows below is an introduction which
+describes the process in a somewhat idealized way.  A much more detailed
+treatment will come in later sections.
+
+The stages that a patch goes through are, generally:
+
+ - Design.  This is where the real requirements for the patch - and the way
+   those requirements will be met - are laid out.  Design work is often
+   done without involving the community, but it is better to do this work
+   in the open if at all possible; it can save a lot of time redesigning
+   things later.
+
+ - Early review.  Patches are posted to the relevant mailing list, and
+   developers on that list reply with any comments they may have.  This
+   process should turn up any major problems with a patch if all goes
+   well.
+
+ - Wider review.  When the patch is getting close to ready for mainline
+   inclusion, it will be accepted by a relevant subsystem maintainer -
+   though this acceptance is not a guarantee that the patch will make it
+   all the way to the mainline.  The patch will show up in the maintainer's
+   subsystem tree and into the staging trees (described below).  When the
+   process works, this step leads to more extensive review of the patch and
+   the discovery of any problems resulting from the integration of this
+   patch with work being done by others.
+
+ - Merging into the mainline.  Eventually, a successful patch will be
+   merged into the mainline repository managed by Linus Torvalds.  More
+   comments and/or problems may surface at this time; it is important that
+   the developer be responsive to these and fix any issues which arise.
+
+ - Stable release.  The number of users potentially affected by the patch
+   is now large, so, once again, new problems may arise.
+
+ - Long-term maintenance.  While it is certainly possible for a developer
+   to forget about code after merging it, that sort of behavior tends to
+   leave a poor impression in the development community.  Merging code
+   eliminates some of the maintenance burden, in that others will fix
+   problems caused by API changes.  But the original developer should
+   continue to take responsibility for the code if it is to remain useful
+   in the longer term.
+
+One of the largest mistakes made by kernel developers (or their employers)
+is to try to cut the process down to a single "merging into the mainline"
+step.  This approach invariably leads to frustration for everybody
+involved.
+
+
+2.3: HOW PATCHES GET INTO THE KERNEL
+
+There is exactly one person who can merge patches into the mainline kernel
+repository: Linus Torvalds.  But, of the over 12,000 patches which went
+into the 2.6.25 kernel, only 250 (around 2%) were directly chosen by Linus
+himself.  The kernel project has long since grown to a size where no single
+developer could possibly inspect and select every patch unassisted.  The
+way the kernel developers have addressed this growth is through the use of
+a lieutenant system built around a chain of trust.
+
+The kernel code base is logically broken down into a set of subsystems:
+networking, specific architecture support, memory management, video
+devices, etc.  Most subsystems have a designated maintainer, a developer
+who has overall responsibility for the code within that subsystem.  These
+subsystem maintainers are the gatekeepers (in a loose way) for the portion
+of the kernel they manage; they are the ones who will (usually) accept a
+patch for inclusion into the mainline kernel.
+
+Subsystem maintainers each manage their own version of the kernel source
+tree, usually (but certainly not always) using the git source management
+tool.  Tools like git (and related tools like quilt or mercurial) allow
+maintainers to track a list of patches, including authorship information
+and other metadata.  At any given time, the maintainer can identify which
+patches in his or her repository are not found in the mainline.
+
+When the merge window opens, top-level maintainers will ask Linus to "pull"
+the patches they have selected for merging from their repositories.  If
+Linus agrees, the stream of patches will flow up into his repository,
+becoming part of the mainline kernel.  The amount of attention that Linus
+pays to specific patches received in a pull operation varies.  It is clear
+that, sometimes, he looks quite closely.  But, as a general rule, Linus
+trusts the subsystem maintainers to not send bad patches upstream.
+
+Subsystem maintainers, in turn, can pull patches from other maintainers.
+For example, the networking tree is built from patches which accumulated
+first in trees dedicated to network device drivers, wireless networking,
+etc.  This chain of repositories can be arbitrarily long, though it rarely
+exceeds two or three links.  Since each maintainer in the chain trusts
+those managing lower-level trees, this process is known as the "chain of
+trust." 
+
+Clearly, in a system like this, getting patches into the kernel depends on
+finding the right maintainer.  Sending patches directly to Linus is not
+normally the right way to go.
+
+
+2.4: STAGING TREES
+
+The chain of subsystem trees guides the flow of patches into the kernel,
+but it also raises an interesting question: what if somebody wants to look
+at all of the patches which are being prepared for the next merge window?
+Developers will be interested in what other changes are pending to see
+whether there are any conflicts to worry about; a patch which changes a
+core kernel function prototype, for example, will conflict with any other
+patches which use the older form of that function.  Reviewers and testers
+want access to the changes in their integrated form before all of those
+changes land in the mainline kernel.  One could pull changes from all of
+the interesting subsystem trees, but that would be a big and error-prone
+job.
+
+The answer comes in the form of staging trees, where subsystem trees are
+collected for testing and review.  The older of these trees, maintained by
+Andrew Morton, is called "-mm" (for memory management, which is how it got
+started).  The -mm tree integrates patches from a long list of subsystem
+trees; it also has some patches aimed at helping with debugging.  
+
+Beyond that, -mm contains a significant collection of patches which have
+been selected by Andrew directly.  These patches may have been posted on a
+mailing list, or they may apply to a part of the kernel for which there is
+no designated subsystem tree.  As a result, -mm operates as a sort of
+subsystem tree of last resort; if there is no other obvious path for a
+patch into the mainline, it is likely to end up in -mm.  Miscellaneous
+patches which accumulate in -mm will eventually either be forwarded on to
+an appropriate subsystem tree or be sent directly to Linus.  In a typical
+development cycle, approximately 10% of the patches going into the mainline
+get there via -mm.
+
+The current -mm patch can always be found from the front page of
+
+	http://kernel.org/
+
+Those who want to see the current state of -mm can get the "-mm of the
+moment" tree, found at:
+
+	http://userweb.kernel.org/~akpm/mmotm/
+
+Use of the MMOTM tree is likely to be a frustrating experience, though;
+there is a definite chance that it will not even compile.
+
+The other staging tree, started more recently, is linux-next, maintained by
+Stephen Rothwell.  The linux-next tree is, by design, a snapshot of what
+the mainline is expected to look like after the next merge window closes.
+Linux-next trees are announced on the linux-kernel and linux-next mailing
+lists when they are assembled; they can be downloaded from:
+
+	http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/
+
+Some information about linux-next has been gathered at:
+
+	http://linux.f-seidel.de/linux-next/pmwiki/
+
+How the linux-next tree will fit into the development process is still
+changing.  As of this writing, the first full development cycle involving
+linux-next (2.6.26) is coming to an end; thus far, it has proved to be a
+valuable resource for finding and fixing integration problems before the
+beginning of the merge window.  See http://lwn.net/Articles/287155/ for
+more information on how linux-next has worked to set up the 2.6.27 merge
+window.
+
+Some developers have begun to suggest that linux-next should be used as the
+target for future development as well.  The linux-next tree does tend to be
+far ahead of the mainline and is more representative of the tree into which
+any new work will be merged.  The downside to this idea is that the
+volatility of linux-next tends to make it a difficult development target.
+See http://lwn.net/Articles/289013/ for more information on this topic, and
+stay tuned; much is still in flux where linux-next is involved.
+
+
+2.5: TOOLS
+
+As can be seen from the above text, the kernel development process depends
+heavily on the ability to herd collections of patches in various
+directions.  The whole thing would not work anywhere near as well as it
+does without suitably powerful tools.  Tutorials on how to use these tools
+are well beyond the scope of this document, but there is space for a few
+pointers.
+
+By far the dominant source code management system used by the kernel
+community is git.  Git is one of a number of distributed version control
+systems being developed in the free software community.  It is well tuned
+for kernel development, in that it performs quite well when dealing with
+large repositories and large numbers of patches.  It also has a reputation
+for being difficult to learn and use, though it has gotten better over
+time.  Some sort of familiarity with git is almost a requirement for kernel
+developers; even if they do not use it for their own work, they'll need git
+to keep up with what other developers (and the mainline) are doing.
+
+Git is now packaged by almost all Linux distributions.  There is a home
+page at 
+
+	http://git.or.cz/
+
+That page has pointers to documentation and tutorials.  One should be
+aware, in particular, of the Kernel Hacker's Guide to git, which has
+information specific to kernel development:
+
+	http://linux.yyz.us/git-howto.html
+
+Among the kernel developers who do not use git, the most popular choice is
+almost certainly Mercurial:
+
+	http://www.selenic.com/mercurial/
+
+Mercurial shares many features with git, but it provides an interface which
+many find easier to use.
+
+The other tool worth knowing about is Quilt:
+
+	http://savannah.nongnu.org/projects/quilt/
+
+Quilt is a patch management system, rather than a source code management
+system.  It does not track history over time; it is, instead, oriented
+toward tracking a specific set of changes against an evolving code base.
+Some major subsystem maintainers use quilt to manage patches intended to go
+upstream.  For the management of certain kinds of trees (-mm, for example),
+quilt is the best tool for the job.
+
+
+2.6: MAILING LISTS
+
+A great deal of Linux kernel development work is done by way of mailing
+lists.  It is hard to be a fully-functioning member of the community
+without joining at least one list somewhere.  But Linux mailing lists also
+represent a potential hazard to developers, who risk getting buried under a
+load of electronic mail, running afoul of the conventions used on the Linux
+lists, or both.
+
+Most kernel mailing lists are run on vger.kernel.org; the master list can
+be found at:
+
+	http://vger.kernel.org/vger-lists.html
+
+There are lists hosted elsewhere, though; a number of them are at
+lists.redhat.com.
+
+The core mailing list for kernel development is, of course, linux-kernel.
+This list is an intimidating place to be; volume can reach 500 messages per
+day, the amount of noise is high, the conversation can be severely
+technical, and participants are not always concerned with showing a high
+degree of politeness.  But there is no other place where the kernel
+development community comes together as a whole; developers who avoid this
+list will miss important information.
+
+There are a few hints which can help with linux-kernel survival:
+
+- Have the list delivered to a separate folder, rather than your main
+  mailbox.  One must be able to ignore the stream for sustained periods of
+  time.
+
+- Do not try to follow every conversation - nobody else does.  It is
+  important to filter on both the topic of interest (though note that
+  long-running conversations can drift away from the original subject
+  without changing the email subject line) and the people who are
+  participating.  
+
+- Do not feed the trolls.  If somebody is trying to stir up an angry
+  response, ignore them.
+
+- When responding to linux-kernel email (or that on other lists) preserve
+  the Cc: header for all involved.  In the absence of a strong reason (such
+  as an explicit request), you should never remove recipients.  Always make
+  sure that the person you are responding to is in the Cc: list.  This
+  convention also makes it unnecessary to explicitly ask to be copied on
+  replies to your postings.
+
+- Search the list archives (and the net as a whole) before asking
+  questions.  Some developers can get impatient with people who clearly
+  have not done their homework.
+
+- Avoid top-posting (the practice of putting your answer above the quoted
+  text you are responding to).  It makes your response harder to read and
+  makes a poor impression.
+
+- Ask on the correct mailing list.  Linux-kernel may be the general meeting
+  point, but it is not the best place to find developers from all
+  subsystems.
+
+The last point - finding the correct mailing list - is a common place for
+beginning developers to go wrong.  Somebody who asks a networking-related
+question on linux-kernel will almost certainly receive a polite suggestion
+to ask on the netdev list instead, as that is the list frequented by most
+networking developers.  Other lists exist for the SCSI, video4linux, IDE,
+filesystem, etc. subsystems.  The best place to look for mailing lists is
+in the MAINTAINERS file packaged with the kernel source.
+
+
+2.7: GETTING STARTED WITH KERNEL DEVELOPMENT
+
+Questions about how to get started with the kernel development process are
+common - from both individuals and companies.  Equally common are missteps
+which make the beginning of the relationship harder than it has to be.
+
+Companies often look to hire well-known developers to get a development
+group started.  This can, in fact, be an effective technique.  But it also
+tends to be expensive and does not do much to grow the pool of experienced
+kernel developers.  It is possible to bring in-house developers up to speed
+on Linux kernel development, given the investment of a bit of time.  Taking
+this time can endow an employer with a group of developers who understand
+the kernel and the company both, and who can help to train others as well.
+Over the medium term, this is often the more profitable approach.
+
+Individual developers are often, understandably, at a loss for a place to
+start.  Beginning with a large project can be intimidating; one often wants
+to test the waters with something smaller first.  This is the point where
+some developers jump into the creation of patches fixing spelling errors or
+minor coding style issues.  Unfortunately, such patches create a level of
+noise which is distracting for the development community as a whole, so,
+increasingly, they are looked down upon.  New developers wishing to
+introduce themselves to the community will not get the sort of reception
+they wish for by these means.
+
+Andrew Morton gives this advice for aspiring kernel developers
+
+	The #1 project for all kernel beginners should surely be "make sure
+	that the kernel runs perfectly at all times on all machines which
+	you can lay your hands on".  Usually the way to do this is to work
+	with others on getting things fixed up (this can require
+	persistence!) but that's fine - it's a part of kernel development.
+
+(http://lwn.net/Articles/283982/).
+
+In the absence of obvious problems to fix, developers are advised to look
+at the current lists of regressions and open bugs in general.  There is
+never any shortage of issues in need of fixing; by addressing these issues,
+developers will gain experience with the process while, at the same time,
+building respect with the rest of the development community.

+3: EARLY-STAGE PLANNING
+
+When contemplating a Linux kernel development project, it can be tempting
+to jump right in and start coding.  As with any significant project,
+though, much of the groundwork for success is best laid before the first
+line of code is written.  Some time spent in early planning and
+communication can save far more time later on.
+
+
+3.1: SPECIFYING THE PROBLEM
+
+Like any engineering project, a successful kernel enhancement starts with a
+clear description of the problem to be solved.  In some cases, this step is
+easy: when a driver is needed for a specific piece of hardware, for
+example.  In others, though, it is tempting to confuse the real problem
+with the proposed solution, and that can lead to difficulties.
+
+Consider an example: some years ago, developers working with Linux audio
+sought a way to run applications without dropouts or other artifacts caused
+by excessive latency in the system.  The solution they arrived at was a
+kernel module intended to hook into the Linux Security Module (LSM)
+framework; this module could be configured to give specific applications
+access to the realtime scheduler.  This module was implemented and sent to
+the linux-kernel mailing list, where it immediately ran into problems.
+
+To the audio developers, this security module was sufficient to solve their
+immediate problem.  To the wider kernel community, though, it was seen as a
+misuse of the LSM framework (which is not intended to confer privileges
+onto processes which they would not otherwise have) and a risk to system
+stability.  Their preferred solutions involved realtime scheduling access
+via the rlimit mechanism for the short term, and ongoing latency reduction
+work in the long term.
+
+The audio community, however, could not see past the particular solution
+they had implemented; they were unwilling to accept alternatives.  The
+resulting disagreement left those developers feeling disillusioned with the
+entire kernel development process; one of them went back to an audio list
+and posted this:
+
+	There are a number of very good Linux kernel developers, but they
+	tend to get outshouted by a large crowd of arrogant fools. Trying
+	to communicate user requirements to these people is a waste of
+	time. They are much too "intelligent" to listen to lesser mortals.
+
+(http://lwn.net/Articles/131776/).
+
+The reality of the situation was different; the kernel developers were far
+more concerned about system stability, long-term maintenance, and finding
+the right solution to the problem than they were with a specific module.
+The moral of the story is to focus on the problem - not a specific solution
+- and to discuss it with the development community before investing in the
+creation of a body of code.
+
+So, when contemplating a kernel development project, one should obtain
+answers to a short set of questions:
+
+ - What, exactly, is the problem which needs to be solved?
+
+ - Who are the users affected by this problem?  Which use cases should the
+   solution address?
+
+ - How does the kernel fall short in addressing that problem now?
+
+Only then does it make sense to start considering possible solutions.
+
+
+3.2: EARLY DISCUSSION
+
+When planning a kernel development project, it makes great sense to hold
+discussions with the community before launching into implementation.  Early
+communication can save time and trouble in a number of ways:
+
+ - It may well be that the problem is addressed by the kernel in ways which
+   you have not understood.  The Linux kernel is large and has a number of
+   features and capabilities which are not immediately obvious.  Not all
+   kernel capabilities are documented as well as one might like, and it is
+   easy to miss things.  Your author has seen the posting of a complete
+   driver which duplicated an existing driver that the new author had been
+   unaware of.  Code which reinvents existing wheels is not only wasteful;
+   it will also not be accepted into the mainline kernel.
+
+ - There may be elements of the proposed solution which will not be
+   acceptable for mainline merging.  It is better to find out about
+   problems like this before writing the code.
+
+ - It's entirely possible that other developers have thought about the
+   problem; they may have ideas for a better solution, and may be willing
+   to help in the creation of that solution.
+
+Years of experience with the kernel development community have taught a
+clear lesson: kernel code which is designed and developed behind closed
+doors invariably has problems which are only revealed when the code is
+released into the community.  Sometimes these problems are severe,
+requiring months or years of effort before the code can be brought up to
+the kernel community's standards.  Some examples include:
+
+ - The Devicescape network stack was designed and implemented for
+   single-processor systems.  It could not be merged into the mainline
+   until it was made suitable for multiprocessor systems.  Retrofitting
+   locking and such into code is a difficult task; as a result, the merging
+   of this code (now called mac80211) was delayed for over a year.
+
+ - The Reiser4 filesystem included a number of capabilities which, in the
+   core kernel developers' opinion, should have been implemented in the
+   virtual filesystem layer instead.  It also included features which could
+   not easily be implemented without exposing the system to user-caused
+   deadlocks.  The late revelation of these problems - and refusal to
+   address some of them - has caused Reiser4 to stay out of the mainline
+   kernel.
+
+ - The AppArmor security module made use of internal virtual filesystem
+   data structures in ways which were considered to be unsafe and
+   unreliable.  This code has since been significantly reworked, but
+   remains outside of the mainline.
+
+In each of these cases, a great deal of pain and extra work could have been
+avoided with some early discussion with the kernel developers.
+
+
+3.3: WHO DO YOU TALK TO?
+
+When developers decide to take their plans public, the next question will
+be: where do we start?  The answer is to find the right mailing list(s) and
+the right maintainer.  For mailing lists, the best approach is to look in
+the MAINTAINERS file for a relevant place to post.  If there is a suitable
+subsystem list, posting there is often preferable to posting on
+linux-kernel; you are more likely to reach developers with expertise in the
+relevant subsystem and the environment may be more supportive.
+
+Finding maintainers can be a bit harder.  Again, the MAINTAINERS file is
+the place to start.  That file tends to not always be up to date, though,
+and not all subsystems are represented there.  The person listed in the
+MAINTAINERS file may, in fact, not be the person who is actually acting in
+that role currently.  So, when there is doubt about who to contact, a
+useful trick is to use git (and "git log" in particular) to see who is
+currently active within the subsystem of interest.  Look at who is writing
+patches, and who, if anybody, is attaching Signed-off-by lines to those
+patches.  Those are the people who will be best placed to help with a new
+development project.
+
+If all else fails, talking to Andrew Morton can be an effective way to
+track down a maintainer for a specific piece of code.
+
+
+3.4: WHEN TO POST?
+
+If possible, posting your plans during the early stages can only be
+helpful.  Describe the problem being solved and any plans that have been
+made on how the implementation will be done.  Any information you can
+provide can help the development community provide useful input on the
+project.
+
+One discouraging thing which can happen at this stage is not a hostile
+reaction, but, instead, little or no reaction at all.  The sad truth of the
+matter is (1) kernel developers tend to be busy, (2) there is no shortage
+of people with grand plans and little code (or even prospect of code) to
+back them up, and (3) nobody is obligated to review or comment on ideas
+posted by others.  If a request-for-comments posting yields little in the
+way of comments, do not assume that it means there is no interest in the
+project.  Unfortunately, you also cannot assume that there are no problems
+with your idea.  The best thing to do in this situation is to proceed,
+keeping the community informed as you go.
+
+
+3.5: GETTING OFFICIAL BUY-IN
+
+If your work is being done in a corporate environment - as most Linux
+kernel work is - you must, obviously, have permission from suitably
+empowered managers before you can post your company's plans or code to a
+public mailing list.  The posting of code which has not been cleared for
+release under a GPL-compatible license can be especially problematic; the
+sooner that a company's management and legal staff can agree on the posting
+of a kernel development project, the better off everybody involved will be.
+
+Some readers may be thinking at this point that their kernel work is
+intended to support a product which does not yet have an officially
+acknowledged existence.  Revealing their employer's plans on a public
+mailing list may not be a viable option.  In cases like this, it is worth
+considering whether the secrecy is really necessary; there is often no real
+need to keep development plans behind closed doors.
+
+That said, there are also cases where a company legitimately cannot
+disclose its plans early in the development process.  Companies with
+experienced kernel developers may choose to proceed in an open-loop manner
+on the assumption that they will be able to avoid serious integration
+problems later.  For companies without that sort of in-house expertise, the
+best option is often to hire an outside developer to review the plans under
+a non-disclosure agreement.  The Linux Foundation operates an NDA program
+designed to help with this sort of situation; more information can be found
+at:
+
+    http://www.linuxfoundation.org/en/NDA_program
+
+This kind of review is often enough to avoid serious problems later on
+without requiring public disclosure of the project.

+4: GETTING THE CODE RIGHT
+
+While there is much to be said for a solid and community-oriented design
+process, the proof of any kernel development project is in the resulting
+code.  It is the code which will be examined by other developers and merged
+(or not) into the mainline tree.  So it is the quality of this code which
+will determine the ultimate success of the project.
+
+This section will examine the coding process.  We'll start with a look at a
+number of ways in which kernel developers can go wrong.  Then the focus
+will shift toward doing things right and the tools which can help in that
+quest.
+
+
+4.1: PITFALLS
+
+* Coding style
+
+The kernel has long had a standard coding style, described in
+Documentation/CodingStyle.  For much of that time, the policies described
+in that file were taken as being, at most, advisory.  As a result, there is
+a substantial amount of code in the kernel which does not meet the coding
+style guidelines.  The presence of that code leads to two independent
+hazards for kernel developers.
+
+The first of these is to believe that the kernel coding standards do not
+matter and are not enforced.  The truth of the matter is that adding new
+code to the kernel is very difficult if that code is not coded according to
+the standard; many developers will request that the code be reformatted
+before they will even review it.  A code base as large as the kernel
+requires some uniformity of code to make it possible for developers to
+quickly understand any part of it.  So there is no longer room for
+strangely-formatted code.
+
+Occasionally, the kernel's coding style will run into conflict with an
+employer's mandated style.  In such cases, the kernel's style will have to
+win before the code can be merged.  Putting code into the kernel means
+giving up a degree of control in a number of ways - including control over
+how the code is formatted.
+
+The other trap is to assume that code which is already in the kernel is
+urgently in need of coding style fixes.  Developers may start to generate
+reformatting patches as a way of gaining familiarity with the process, or
+as a way of getting their name into the kernel changelogs - or both.  But
+pure coding style fixes are seen as noise by the development community;
+they tend to get a chilly reception.  So this type of patch is best
+avoided.  It is natural to fix the style of a piece of code while working
+on it for other reasons, but coding style changes should not be made for
+their own sake.
+
+The coding style document also should not be read as an absolute law which
+can never be transgressed.  If there is a good reason to go against the
+style (a line which becomes far less readable if split to fit within the
+80-column limit, for example), just do it.
+
+
+* Abstraction layers
+
+Computer Science professors teach students to make extensive use of
+abstraction layers in the name of flexibility and information hiding.
+Certainly the kernel makes extensive use of abstraction; no project
+involving several million lines of code could do otherwise and survive.
+But experience has shown that excessive or premature abstraction can be
+just as harmful as premature optimization.  Abstraction should be used to
+the level required and no further.
+
+At a simple level, consider a function which has an argument which is
+always passed as zero by all callers.  One could retain that argument just
+in case somebody eventually needs to use the extra flexibility that it
+provides.  By that time, though, chances are good that the code which
+implements this extra argument has been broken in some subtle way which was
+never noticed - because it has never been used.  Or, when the need for
+extra flexibility arises, it does not do so in a way which matches the
+programmer's early expectation.  Kernel developers will routinely submit
+patches to remove unused arguments; they should, in general, not be added
+in the first place.
+
+Abstraction layers which hide access to hardware - often to allow the bulk
+of a driver to be used with multiple operating systems - are especially
+frowned upon.  Such layers obscure the code and may impose a performance
+penalty; they do not belong in the Linux kernel.
+
+On the other hand, if you find yourself copying significant amounts of code
+from another kernel subsystem, it is time to ask whether it would, in fact,
+make sense to pull out some of that code into a separate library or to
+implement that functionality at a higher level.  There is no value in
+replicating the same code throughout the kernel.
+
+
+* #ifdef and preprocessor use in general
+
+The C preprocessor seems to present a powerful temptation to some C
+programmers, who see it as a way to efficiently encode a great deal of
+flexibility into a source file.  But the preprocessor is not C, and heavy
+use of it results in code which is much harder for others to read and
+harder for the compiler to check for correctness.  Heavy preprocessor use
+is almost always a sign of code which needs some cleanup work.
+
+Conditional compilation with #ifdef is, indeed, a powerful feature, and it
+is used within the kernel.  But there is little desire to see code which is
+sprinkled liberally with #ifdef blocks.  As a general rule, #ifdef use
+should be confined to header files whenever possible.
+Conditionally-compiled code can be confined to functions which, if the code
+is not to be present, simply become empty.  The compiler will then quietly
+optimize out the call to the empty function.  The result is far cleaner
+code which is easier to follow.
+
+C preprocessor macros present a number of hazards, including possible
+multiple evaluation of expressions with side effects and no type safety.
+If you are tempted to define a macro, consider creating an inline function
+instead.  The code which results will be the same, but inline functions are
+easier to read, do not evaluate their arguments multiple times, and allow
+the compiler to perform type checking on the arguments and return value.
+
+
+* Inline functions
+
+Inline functions present a hazard of their own, though.  Programmers can
+become enamored of the perceived efficiency inherent in avoiding a function
+call and fill a source file with inline functions.  Those functions,
+however, can actually reduce performance.  Since their code is replicated
+at each call site, they end up bloating the size of the compiled kernel.
+That, in turn, creates pressure on the processor's memory caches, which can
+slow execution dramatically.  Inline functions, as a rule, should be quite
+small and relatively rare.  The cost of a function call, after all, is not
+that high; the creation of large numbers of inline functions is a classic
+example of premature optimization.
+
+In general, kernel programmers ignore cache effects at their peril.  The
+classic time/space tradeoff taught in beginning data structures classes
+often does not apply to contemporary hardware.  Space *is* time, in that a
+larger program will run slower than one which is more compact.
+
+
+* Locking
+
+In May, 2006, the "Devicescape" networking stack was, with great
+fanfare, released under the GPL and made available for inclusion in the
+mainline kernel.  This donation was welcome news; support for wireless
+networking in Linux was considered substandard at best, and the Devicescape
+stack offered the promise of fixing that situation.  Yet, this code did not
+actually make it into the mainline until June, 2007 (2.6.22).  What
+happened?
+
+This code showed a number of signs of having been developed behind
+corporate doors.  But one large problem in particular was that it was not
+designed to work on multiprocessor systems.  Before this networking stack
+(now called mac80211) could be merged, a locking scheme needed to be
+retrofitted onto it.  
+
+Once upon a time, Linux kernel code could be developed without thinking
+about the concurrency issues presented by multiprocessor systems.  Now,
+however, this document is being written on a dual-core laptop.  Even on
+single-processor systems, work being done to improve responsiveness will
+raise the level of concurrency within the kernel.  The days when kernel
+code could be written without thinking about locking are long past.
+
+Any resource (data structures, hardware registers, etc.) which could be
+accessed concurrently by more than one thread must be protected by a lock.
+New code should be written with this requirement in mind; retrofitting
+locking after the fact is a rather more difficult task.  Kernel developers
+should take the time to understand the available locking primitives well
+enough to pick the right tool for the job.  Code which shows a lack of
+attention to concurrency will have a difficult path into the mainline.
+
+
+* Regressions
+
+One final hazard worth mentioning is this: it can be tempting to make a
+change (which may bring big improvements) which causes something to break
+for existing users.  This kind of change is called a "regression," and
+regressions have become most unwelcome in the mainline kernel.  With few
+exceptions, changes which cause regressions will be backed out if the
+regression cannot be fixed in a timely manner.  Far better to avoid the
+regression in the first place.
+
+It is often argued that a regression can be justified if it causes things
+to work for more people than it creates problems for.  Why not make a
+change if it brings new functionality to ten systems for each one it
+breaks?  The best answer to this question was expressed by Linus in July,
+2007:
+
+	So we don't fix bugs by introducing new problems.  That way lies
+	madness, and nobody ever knows if you actually make any real
+	progress at all. Is it two steps forwards, one step back, or one
+	step forward and two steps back?
+
+(http://lwn.net/Articles/243460/).
+
+An especially unwelcome type of regression is any sort of change to the
+user-space ABI.  Once an interface has been exported to user space, it must
+be supported indefinitely.  This fact makes the creation of user-space
+interfaces particularly challenging: since they cannot be changed in
+incompatible ways, they must be done right the first time.  For this
+reason, a great deal of thought, clear documentation, and wide review for
+user-space interfaces is always required.
+
+
+
+4.2: CODE CHECKING TOOLS
+
+For now, at least, the writing of error-free code remains an ideal that few
+of us can reach.  What we can hope to do, though, is to catch and fix as
+many of those errors as possible before our code goes into the mainline
+kernel.  To that end, the kernel developers have put together an impressive
+array of tools which can catch a wide variety of obscure problems in an
+automated way.  Any problem caught by the computer is a problem which will
+not afflict a user later on, so it stands to reason that the automated
+tools should be used whenever possible.
+
+The first step is simply to heed the warnings produced by the compiler.
+Contemporary versions of gcc can detect (and warn about) a large number of
+potential errors.  Quite often, these warnings point to real problems.
+Code submitted for review should, as a rule, not produce any compiler
+warnings.  When silencing warnings, take care to understand the real cause
+and try to avoid "fixes" which make the warning go away without addressing
+its cause.
+
+Note that not all compiler warnings are enabled by default.  Build the
+kernel with "make EXTRA_CFLAGS=-W" to get the full set.
+
+The kernel provides several configuration options which turn on debugging
+features; most of these are found in the "kernel hacking" submenu.  Several
+of these options should be turned on for any kernel used for development or
+testing purposes.  In particular, you should turn on:
+
+ - ENABLE_WARN_DEPRECATED, ENABLE_MUST_CHECK, and FRAME_WARN to get an
+   extra set of warnings for problems like the use of deprecated interfaces
+   or ignoring an important return value from a function.  The output
+   generated by these warnings can be verbose, but one need not worry about
+   warnings from other parts of the kernel.
+
+ - DEBUG_OBJECTS will add code to track the lifetime of various objects
+   created by the kernel and warn when things are done out of order.  If
+   you are adding a subsystem which creates (and exports) complex objects
+   of its own, consider adding support for the object debugging
+   infrastructure.
+
+ - DEBUG_SLAB can find a variety of memory allocation and use errors; it
+   should be used on most development kernels.
+
+ - DEBUG_SPINLOCK, DEBUG_SPINLOCK_SLEEP, and DEBUG_MUTEXES will find a
+   number of common locking errors.
+
+There are quite a few other debugging options, some of which will be
+discussed below.  Some of them have a significant performance impact and
+should not be used all of the time.  But some time spent learning the
+available options will likely be paid back many times over in short order. 
+
+One of the heavier debugging tools is the locking checker, or "lockdep."
+This tool will track the acquisition and release of every lock (spinlock or
+mutex) in the system, the order in which locks are acquired relative to
+each other, the current interrupt environment, and more.  It can then
+ensure that locks are always acquired in the same order, that the same
+interrupt assumptions apply in all situations, and so on.  In other words,
+lockdep can find a number of scenarios in which the system could, on rare
+occasion, deadlock.  This kind of problem can be painful (for both
+developers and users) in a deployed system; lockdep allows them to be found
+in an automated manner ahead of time.  Code with any sort of non-trivial
+locking should be run with lockdep enabled before being submitted for
+inclusion. 
+
+As a diligent kernel programmer, you will, beyond doubt, check the return
+status of any operation (such as a memory allocation) which can fail.  The
+fact of the matter, though, is that the resulting failure recovery paths
+are, probably, completely untested.  Untested code tends to be broken code;
+you could be much more confident of your code if all those error-handling
+paths had been exercised a few times.
+
+The kernel provides a fault injection framework which can do exactly that,
+especially where memory allocations are involved.  With fault injection
+enabled, a configurable percentage of memory allocations will be made to
+fail; these failures can be restricted to a specific range of code.
+Running with fault injection enabled allows the programmer to see how the
+code responds when things go badly.  See
+Documentation/fault-injection/fault-injection.text for more information on
+how to use this facility.
+
+Other kinds of errors can be found with the "sparse" static analysis tool.
+With sparse, the programmer can be warned about confusion between
+user-space and kernel-space addresses, mixture of big-endian and
+small-endian quantities, the passing of integer values where a set of bit
+flags is expected, and so on.  Sparse must be installed separately (it can
+be found at http://www.kernel.org/pub/software/devel/sparse/ if your
+distributor does not package it); it can then be run on the code by adding
+"C=1" to your make command.
+
+Other kinds of portability errors are best found by compiling your code for
+other architectures.  If you do not happen to have an S/390 system or a
+Blackfin development board handy, you can still perform the compilation
+step.  A large set of cross compilers for x86 systems can be found at 
+
+	http://www.kernel.org/pub/tools/crosstool/
+
+Some time spent installing and using these compilers will help avoid
+embarrassment later.
+
+
+4.3: DOCUMENTATION
+
+Documentation has often been more the exception than the rule with kernel
+development.  Even so, adequate documentation will help to ease the merging
+of new code into the kernel, make life easier for other developers, and
+will be helpful for your users.  In many cases, the addition of
+documentation has become essentially mandatory.
+
+The first piece of documentation for any patch is its associated
+changelog.  Log entries should describe the problem being solved, the form
+of the solution, the people who worked on the patch, any relevant
+effects on performance, and anything else that might be needed to
+understand the patch.
+
+Any code which adds a new user-space interface - including new sysfs or
+/proc files - should include documentation of that interface which enables
+user-space developers to know what they are working with.  See
+Documentation/ABI/README for a description of how this documentation should
+be formatted and what information needs to be provided.
+
+The file Documentation/kernel-parameters.txt describes all of the kernel's
+boot-time parameters.  Any patch which adds new parameters should add the
+appropriate entries to this file.
+
+Any new configuration options must be accompanied by help text which
+clearly explains the options and when the user might want to select them. 
+
+Internal API information for many subsystems is documented by way of
+specially-formatted comments; these comments can be extracted and formatted
+in a number of ways by the "kernel-doc" script.  If you are working within
+a subsystem which has kerneldoc comments, you should maintain them and add
+them, as appropriate, for externally-available functions.  Even in areas
+which have not been so documented, there is no harm in adding kerneldoc
+comments for the future; indeed, this can be a useful activity for
+beginning kernel developers.  The format of these comments, along with some
+information on how to create kerneldoc templates can be found in the file
+Documentation/kernel-doc-nano-HOWTO.txt.
+
+Anybody who reads through a significant amount of existing kernel code will
+note that, often, comments are most notable by their absence.  Once again,
+the expectations for new code are higher than they were in the past;
+merging uncommented code will be harder.  That said, there is little desire
+for verbosely-commented code.  The code should, itself, be readable, with
+comments explaining the more subtle aspects.
+
+Certain things should always be commented.  Uses of memory barriers should
+be accompanied by a line explaining why the barrier is necessary.  The
+locking rules for data structures generally need to be explained somewhere.
+Major data structures need comprehensive documentation in general.
+Non-obvious dependencies between separate bits of code should be pointed
+out.  Anything which might tempt a code janitor to make an incorrect
+"cleanup" needs a comment saying why it is done the way it is.  And so on.
+
+
+4.4: INTERNAL API CHANGES
+
+The binary interface provided by the kernel to user space cannot be broken
+except under the most severe circumstances.  The kernel's internal
+programming interfaces, instead, are highly fluid and can be changed when
+the need arises.  If you find yourself having to work around a kernel API,
+or simply not using a specific functionality because it does not meet your
+needs, that may be a sign that the API needs to change.  As a kernel
+developer, you are empowered to make such changes.
+
+There are, of course, some catches.  API changes can be made, but they need
+to be well justified.  So any patch making an internal API change should be
+accompanied by a description of what the change is and why it is
+necessary.  This kind of change should also be broken out into a separate
+patch, rather than buried within a larger patch.
+
+The other catch is that a developer who changes an internal API is
+generally charged with the task of fixing any code within the kernel tree
+which is broken by the change.  For a widely-used function, this duty can
+lead to literally hundreds or thousands of changes - many of which are
+likely to conflict with work being done by other developers.  Needless to
+say, this can be a large job, so it is best to be sure that the
+justification is solid.
+
+When making an incompatible API change, one should, whenever possible,
+ensure that code which has not been updated is caught by the compiler.  
+This will help you to be sure that you have found all in-tree uses of that
+interface.  It will also alert developers of out-of-tree code that there is
+a change that they need to respond to.  Supporting out-of-tree code is not
+something that kernel developers need to be worried about, but we also do
+not have to make life harder for out-of-tree developers than it it needs to
+be.

+5: POSTING PATCHES
+
+Sooner or later, the time comes when your work is ready to be presented to
+the community for review and, eventually, inclusion into the mainline
+kernel.  Unsurprisingly, the kernel development community has evolved a set
+of conventions and procedures which are used in the posting of patches;
+following them will make life much easier for everybody involved.  This
+document will attempt to cover these expectations in reasonable detail;
+more information can also be found in the files SubmittingPatches,
+SubmittingDrivers, and SubmitChecklist in the kernel documentation
+directory.
+
+
+5.1: WHEN TO POST
+
+There is a constant temptation to avoid posting patches before they are
+completely "ready."  For simple patches, that is not a problem.  If the
+work being done is complex, though, there is a lot to be gained by getting
+feedback from the community before the work is complete.  So you should
+consider posting in-progress work, or even making a git tree available so
+that interested developers can catch up with your work at any time.
+
+When posting code which is not yet considered ready for inclusion, it is a
+good idea to say so in the posting itself.  Also mention any major work
+which remains to be done and any known problems.  Fewer people will look at
+patches which are known to be half-baked, but those who do will come in
+with the idea that they can help you drive the work in the right direction.
+
+
+5.2: BEFORE CREATING PATCHES
+
+There are a number of things which should be done before you consider
+sending patches to the development community.  These include:
+
+ - Test the code to the extent that you can.  Make use of the kernel's
+   debugging tools, ensure that the kernel will build with all reasonable
+   combinations of configuration options, use cross-compilers to build for
+   different architectures, etc.
+
+ - Make sure your code is compliant with the kernel coding style
+   guidelines.
+
+ - Does your change have performance implications?  If so, you should run
+   benchmarks showing what the impact (or benefit) of your change is; a
+   summary of the results should be included with the patch.
+
+ - Be sure that you have the right to post the code.  If this work was done
+   for an employer, the employer likely has a right to the work and must be
+   agreeable with its release under the GPL.
+
+As a general rule, putting in some extra thought before posting code almost
+always pays back the effort in short order.
+
+
+5.3: PATCH PREPARATION
+
+The preparation of patches for posting can be a surprising amount of work,
+but, once again, attempting to save time here is not generally advisable
+even in the short term.
+
+Patches must be prepared against a specific version of the kernel.  As a
+general rule, a patch should be based on the current mainline as found in
+Linus's git tree.  It may become necessary to make versions against -mm,
+linux-next, or a subsystem tree, though, to facilitate wider testing and
+review.  Depending on the area of your patch and what is going on
+elsewhere, basing a patch against these other trees can require a
+significant amount of work resolving conflicts and dealing with API
+changes.
+
+Only the most simple changes should be formatted as a single patch;
+everything else should be made as a logical series of changes.  Splitting
+up patches is a bit of an art; some developers spend a long time figuring
+out how to do it in the way that the community expects.  There are a few
+rules of thumb, however, which can help considerably:
+
+ - The patch series you post will almost certainly not be the series of
+   changes found in your working revision control system.  Instead, the
+   changes you have made need to be considered in their final form, then
+   split apart in ways which make sense.  The developers are interested in
+   discrete, self-contained changes, not the path you took to get to those
+   changes.
+
+ - Each logically independent change should be formatted as a separate
+   patch.  These changes can be small ("add a field to this structure") or
+   large (adding a significant new driver, for example), but they should be
+   conceptually small and amenable to a one-line description.  Each patch
+   should make a specific change which can be reviewed on its own and
+   verified to do what it says it does.
+
+ - As a way of restating the guideline above: do not mix different types of
+   changes in the same patch.  If a single patch fixes a critical security
+   bug, rearranges a few structures, and reformats the code, there is a
+   good chance that it will be passed over and the important fix will be
+   lost.
+
+ - Each patch should yield a kernel which builds and runs properly; if your
+   patch series is interrupted in the middle, the result should still be a
+   working kernel.  Partial application of a patch series is a common
+   scenario when the "git bisect" tool is used to find regressions; if the
+   result is a broken kernel, you will make life harder for developers and
+   users who are engaging in the noble work of tracking down problems.
+
+ - Do not overdo it, though.  One developer recently posted a set of edits
+   to a single file as 500 separate patches - an act which did not make him
+   the most popular person on the kernel mailing list.  A single patch can
+   be reasonably large as long as it still contains a single *logical*
+   change. 
+
+ - It can be tempting to add a whole new infrastructure with a series of
+   patches, but to leave that infrastructure unused until the final patch
+   in the series enables the whole thing.  This temptation should be
+   avoided if possible; if that series adds regressions, bisection will
+   finger the last patch as the one which caused the problem, even though
+   the real bug is elsewhere.  Whenever possible, a patch which adds new
+   code should make that code active immediately.
+
+Working to create the perfect patch series can be a frustrating process
+which takes quite a bit of time and thought after the "real work" has been
+done.  When done properly, though, it is time well spent.
+
+
+5.4: PATCH FORMATTING
+
+So now you have a perfect series of patches for posting, but the work is
+not done quite yet.  Each patch needs to be formatted into a message which
+quickly and clearly communicates its purpose to the rest of the world.  To
+that end, each patch will be composed of the following:
+
+ - An optional "From" line naming the author of the patch.  This line is
+   only necessary if you are passing on somebody else's patch via email,
+   but it never hurts to add it when in doubt.
+
+ - A one-line description of what the patch does.  This message should be
+   enough for a reader who sees it with no other context to figure out the
+   scope of the patch; it is the line that will show up in the "short form"
+   changelogs.  This message is usually formatted with the relevant
+   subsystem name first, followed by the purpose of the patch.  For
+   example:
+
+	gpio: fix build on CONFIG_GPIO_SYSFS=n
+
+ - A blank line followed by a detailed description of the contents of the
+   patch.  This description can be as long as is required; it should say
+   what the patch does and why it should be applied to the kernel.
+
+ - One or more tag lines, with, at a minimum, one Signed-off-by: line from
+   the author of the patch.  Tags will be described in more detail below.
+
+The above three items should, normally, be the text used when committing
+the change to a revision control system.  They are followed by:
+
+ - The patch itself, in the unified ("-u") patch format.  Using the "-p"
+   option to diff will associate function names with changes, making the
+   resulting patch easier for others to read.
+
+You should avoid including changes to irrelevant files (those generated by
+the build process, for example, or editor backup files) in the patch.  The
+file "dontdiff" in the Documentation directory can help in this regard;
+pass it to diff with the "-X" option.
+
+The tags mentioned above are used to describe how various developers have
+been associated with the development of this patch.  They are described in
+detail in the SubmittingPatches document; what follows here is a brief
+summary.  Each of these lines has the format:
+
+	tag: Full Name <email address>  optional-other-stuff
+
+The tags in common use are:
+
+ - Signed-off-by: this is a developer's certification that he or she has
+   the right to submit the patch for inclusion into the kernel.  It is an
+   agreement to the Developer's Certificate of Origin, the full text of
+   which can be found in Documentation/SubmittingPatches.  Code without a
+   proper signoff cannot be merged into the mainline.
+
+ - Acked-by: indicates an agreement by another developer (often a
+   maintainer of the relevant code) that the patch is appropriate for
+   inclusion into the kernel.
+
+ - Tested-by: states that the named person has tested the patch and found
+   it to work.
+
+ - Reviewed-by: the named developer has reviewed the patch for correctness;
+   see the reviewer's statement in Documentation/SubmittingPatches for more
+   detail.
+
+ - Reported-by: names a user who reported a problem which is fixed by this
+   patch; this tag is used to give credit to the (often underappreciated)
+   people who test our code and let us know when things do not work
+   correctly.
+
+ - Cc: the named person received a copy of the patch and had the
+   opportunity to comment on it.
+
+Be careful in the addition of tags to your patches: only Cc: is appropriate
+for addition without the explicit permission of the person named.
+
+
+5.5: SENDING THE PATCH
+
+Before you mail your patches, there are a couple of other things you should
+take care of:
+
+ - Are you sure that your mailer will not corrupt the patches?  Patches
+   which have had gratuitous white-space changes or line wrapping performed
+   by the mail client will not apply at the other end, and often will not
+   be examined in any detail.  If there is any doubt at all, mail the patch
+   to yourself and convince yourself that it shows up intact.  
+
+   Documentation/email-clients.txt has some helpful hints on making
+   specific mail clients work for sending patches.
+
+ - Are you sure your patch is free of silly mistakes?  You should always
+   run patches through scripts/checkpatch.pl and address the complaints it
+   comes up with.  Please bear in mind that checkpatch.pl, while being the
+   embodiment of a fair amount of thought about what kernel patches should
+   look like, is not smarter than you.  If fixing a checkpatch.pl complaint
+   would make the code worse, don't do it.
+
+Patches should always be sent as plain text.  Please do not send them as
+attachments; that makes it much harder for reviewers to quote sections of
+the patch in their replies.  Instead, just put the patch directly into your
+message.
+
+When mailing patches, it is important to send copies to anybody who might
+be interested in it.  Unlike some other projects, the kernel encourages
+people to err on the side of sending too many copies; don't assume that the
+relevant people will see your posting on the mailing lists.  In particular,
+copies should go to:
+
+ - The maintainer(s) of the affected subsystem(s).  As described earlier,
+   the MAINTAINERS file is the first place to look for these people.
+
+ - Other developers who have been working in the same area - especially
+   those who might be working there now.  Using git to see who else has
+   modified the files you are working on can be helpful.
+
+ - If you are responding to a bug report or a feature request, copy the
+   original poster as well.
+
+ - Send a copy to the relevant mailing list, or, if nothing else applies,
+   the linux-kernel list.
+
+ - If you are fixing a bug, think about whether the fix should go into the
+   next stable update.  If so, stable@kernel.org should get a copy of the
+   patch.  Also add a "Cc: stable@kernel.org" to the tags within the patch
+   itself; that will cause the stable team to get a notification when your
+   fix goes into the mainline.
+
+When selecting recipients for a patch, it is good to have an idea of who
+you think will eventually accept the patch and get it merged.  While it
+is possible to send patches directly to Linus Torvalds and have him merge
+them, things are not normally done that way.  Linus is busy, and there are
+subsystem maintainers who watch over specific parts of the kernel.  Usually
+you will be wanting that maintainer to merge your patches.  If there is no
+obvious maintainer, Andrew Morton is often the patch target of last resort.
+
+Patches need good subject lines.  The canonical format for a patch line is
+something like:
+
+	[PATCH nn/mm] subsys: one-line description of the patch
+
+where "nn" is the ordinal number of the patch, "mm" is the total number of
+patches in the series, and "subsys" is the name of the affected subsystem.
+Clearly, nn/mm can be omitted for a single, standalone patch.  
+
+If you have a significant series of patches, it is customary to send an
+introductory description as part zero.  This convention is not universally
+followed though; if you use it, remember that information in the
+introduction does not make it into the kernel changelogs.  So please ensure
+that the patches, themselves, have complete changelog information.
+
+In general, the second and following parts of a multi-part patch should be
+sent as a reply to the first part so that they all thread together at the
+receiving end.  Tools like git and quilt have commands to mail out a set of
+patches with the proper threading.  If you have a long series, though, and
+are using git, please provide the --no-chain-reply-to option to avoid
+creating exceptionally deep nesting.

+6: FOLLOWTHROUGH
+
+At this point, you have followed the guidelines given so far and, with the
+addition of your own engineering skills, have posted a perfect series of
+patches.  One of the biggest mistakes that even experienced kernel
+developers can make is to conclude that their work is now done.  In truth,
+posting patches indicates a transition into the next stage of the process,
+with, possibly, quite a bit of work yet to be done.
+
+It is a rare patch which is so good at its first posting that there is no
+room for improvement.  The kernel development process recognizes this fact,
+and, as a result, is heavily oriented toward the improvement of posted
+code.  You, as the author of that code, will be expected to work with the
+kernel community to ensure that your code is up to the kernel's quality
+standards.  A failure to participate in this process is quite likely to
+prevent the inclusion of your patches into the mainline.
+
+
+6.1: WORKING WITH REVIEWERS
+
+A patch of any significance will result in a number of comments from other
+developers as they review the code.  Working with reviewers can be, for
+many developers, the most intimidating part of the kernel development
+process.  Life can be made much easier, though, if you keep a few things in
+mind:
+
+ - If you have explained your patch well, reviewers will understand its
+   value and why you went to the trouble of writing it.  But that value
+   will not keep them from asking a fundamental question: what will it be
+   like to maintain a kernel with this code in it five or ten years later?
+   Many of the changes you may be asked to make - from coding style tweaks
+   to substantial rewrites - come from the understanding that Linux will
+   still be around and under development a decade from now.
+
+ - Code review is hard work, and it is a relatively thankless occupation;
+   people remember who wrote kernel code, but there is little lasting fame
+   for those who reviewed it.  So reviewers can get grumpy, especially when
+   they see the same mistakes being made over and over again.  If you get a
+   review which seems angry, insulting, or outright offensive, resist the
+   impulse to respond in kind.  Code review is about the code, not about
+   the people, and code reviewers are not attacking you personally.
+
+ - Similarly, code reviewers are not trying to promote their employers'
+   agendas at the expense of your own.  Kernel developers often expect to
+   be working on the kernel years from now, but they understand that their
+   employer could change.  They truly are, almost without exception,
+   working toward the creation of the best kernel they can; they are not
+   trying to create discomfort for their employers' competitors.
+
+What all of this comes down to is that, when reviewers send you comments,
+you need to pay attention to the technical observations that they are
+making.  Do not let their form of expression or your own pride keep that
+from happening.  When you get review comments on a patch, take the time to
+understand what the reviewer is trying to say.  If possible, fix the things
+that the reviewer is asking you to fix.  And respond back to the reviewer:
+thank them, and describe how you will answer their questions.
+
+Note that you do not have to agree with every change suggested by
+reviewers.  If you believe that the reviewer has misunderstood your code,
+explain what is really going on.  If you have a technical objection to a
+suggested change, describe it and justify your solution to the problem.  If
+your explanations make sense, the reviewer will accept them.  Should your
+explanation not prove persuasive, though, especially if others start to
+agree with the reviewer, take some time to think things over again.  It can
+be easy to become blinded by your own solution to a problem to the point
+that you don't realize that something is fundamentally wrong or, perhaps,
+you're not even solving the right problem.
+
+One fatal mistake is to ignore review comments in the hope that they will
+go away.  They will not go away.  If you repost code without having
+responded to the comments you got the time before, you're likely to find
+that your patches go nowhere.
+
+Speaking of reposting code: please bear in mind that reviewers are not
+going to remember all the details of the code you posted the last time
+around.  So it is always a good idea to remind reviewers of previously
+raised issues and how you dealt with them; the patch changelog is a good
+place for this kind of information.  Reviewers should not have to search
+through list archives to familiarize themselves with what was said last
+time; if you help them get a running start, they will be in a better mood
+when they revisit your code.
+
+What if you've tried to do everything right and things still aren't going
+anywhere?  Most technical disagreements can be resolved through discussion,
+but there are times when somebody simply has to make a decision.  If you
+honestly believe that this decision is going against you wrongly, you can
+always try appealing to a higher power.  As of this writing, that higher
+power tends to be Andrew Morton.  Andrew has a great deal of respect in the
+kernel development community; he can often unjam a situation which seems to
+be hopelessly blocked.  Appealing to Andrew should not be done lightly,
+though, and not before all other alternatives have been explored.  And bear
+in mind, of course, that he may not agree with you either.
+
+
+6.2: WHAT HAPPENS NEXT
+
+If a patch is considered to be a good thing to add to the kernel, and once
+most of the review issues have been resolved, the next step is usually
+entry into a subsystem maintainer's tree.  How that works varies from one
+subsystem to the next; each maintainer has his or her own way of doing
+things.  In particular, there may be more than one tree - one, perhaps,
+dedicated to patches planned for the next merge window, and another for
+longer-term work.  
+
+For patches applying to areas for which there is no obvious subsystem tree
+(memory management patches, for example), the default tree often ends up
+being -mm.  Patches which affect multiple subsystems can also end up going
+through the -mm tree.
+
+Inclusion into a subsystem tree can bring a higher level of visibility to a
+patch.  Now other developers working with that tree will get the patch by
+default.  Subsystem trees typically feed into -mm and linux-next as well,
+making their contents visible to the development community as a whole.  At
+this point, there's a good chance that you will get more comments from a
+new set of reviewers; these comments need to be answered as in the previous
+round.
+
+What may also happen at this point, depending on the nature of your patch,
+is that conflicts with work being done by others turn up.  In the worst
+case, heavy patch conflicts can result in some work being put on the back
+burner so that the remaining patches can be worked into shape and merged.
+Other times, conflict resolution will involve working with the other
+developers and, possibly, moving some patches between trees to ensure that
+everything applies cleanly.  This work can be a pain, but count your
+blessings: before the advent of the linux-next tree, these conflicts often
+only turned up during the merge window and had to be addressed in a hurry.
+Now they can be resolved at leisure, before the merge window opens.
+
+Some day, if all goes well, you'll log on and see that your patch has been
+merged into the mainline kernel.  Congratulations!  Once the celebration is
+complete (and you have added yourself to the MAINTAINERS file), though, it
+is worth remembering an important little fact: the job still is not done.
+Merging into the mainline brings its own challenges.
+
+To begin with, the visibility of your patch has increased yet again.  There
+may be a new round of comments from developers who had not been aware of
+the patch before.  It may be tempting to ignore them, since there is no
+longer any question of your code being merged.  Resist that temptation,
+though; you still need to be responsive to developers who have questions or
+suggestions.
+
+More importantly, though: inclusion into the mainline puts your code into
+the hands of a much larger group of testers.  Even if you have contributed
+a driver for hardware which is not yet available, you will be surprised by
+how many people will build your code into their kernels.  And, of course,
+where there are testers, there will be bug reports.
+
+The worst sort of bug reports are regressions.  If your patch causes a
+regression, you'll find an uncomfortable number of eyes upon you;
+regressions need to be fixed as soon as possible.  If you are unwilling or
+unable to fix the regression (and nobody else does it for you), your patch
+will almost certainly be removed during the stabilization period.  Beyond
+negating all of the work you have done to get your patch into the mainline,
+having a patch pulled as the result of a failure to fix a regression could
+well make it harder for you to get work merged in the future.
+
+After any regressions have been dealt with, there may be other, ordinary
+bugs to deal with.  The stabilization period is your best opportunity to
+fix these bugs and ensure that your code's debut in a mainline kernel
+release is as solid as possible.  So, please, answer bug reports, and fix
+the problems if at all possible.  That's what the stabilization period is
+for; you can start creating cool new patches once any problems with the old
+ones have been taken care of.
+
+And don't forget that there are other milestones which may also create bug
+reports: the next mainline stable release, when prominent distributors pick
+up a version of the kernel containing your patch, etc.  Continuing to
+respond to these reports is a matter of basic pride in your work.  If that
+is insufficient motivation, though, it's also worth considering that the
+development community remembers developers who lose interest in their code
+after it's merged.  The next time you post a patch, they will be evaluating
+it with the assumption that you will not be around to maintain it
+afterward.
+
+
+6.3: OTHER THINGS THAT CAN HAPPEN
+
+One day, you may open your mail client and see that somebody has mailed you
+a patch to your code.  That is one of the advantages of having your code
+out there in the open, after all.  If you agree with the patch, you can
+either forward it on to the subsystem maintainer (be sure to include a
+proper From: line so that the attribution is correct, and add a signoff of
+your own), or send an Acked-by: response back and let the original poster
+send it upward.
+
+If you disagree with the patch, send a polite response explaining why.  If
+possible, tell the author what changes need to be made to make the patch
+acceptable to you.  There is a certain resistance to merging patches which
+are opposed by the author and maintainer of the code, but it only goes so
+far.  If you are seen as needlessly blocking good work, those patches will
+eventually flow around you and get into the mainline anyway.  In the Linux
+kernel, nobody has absolute veto power over any code.  Except maybe Linus.
+
+On very rare occasion, you may see something completely different: another
+developer posts a different solution to your problem.  At that point,
+chances are that one of the two patches will not be merged, and "mine was
+here first" is not considered to be a compelling technical argument.  If
+somebody else's patch displaces yours and gets into the mainline, there is
+really only one way to respond: be pleased that your problem got solved and
+get on with your work.  Having one's work shoved aside in this manner can
+be hurtful and discouraging, but the community will remember your reaction
+long after they have forgotten whose patch actually got merged.

+7: ADVANCED TOPICS
+
+At this point, hopefully, you have a handle on how the development process
+works.  There is still more to learn, however!  This section will cover a
+number of topics which can be helpful for developers wanting to become a
+regular part of the Linux kernel development process.
+
+7.1: MANAGING PATCHES WITH GIT
+
+The use of distributed version control for the kernel began in early 2002,
+when Linus first started playing with the proprietary BitKeeper
+application.  While BitKeeper was controversial, the approach to software
+version management it embodied most certainly was not.  Distributed version
+control enabled an immediate acceleration of the kernel development
+project.  In current times, there are several free alternatives to
+BitKeeper.  For better or for worse, the kernel project has settled on git
+as its tool of choice.
+
+Managing patches with git can make life much easier for the developer,
+especially as the volume of those patches grows.  Git also has its rough
+edges and poses certain hazards; it is a young and powerful tool which is
+still being civilized by its developers.  This document will not attempt to
+teach the reader how to use git; that would be sufficient material for a
+long document in its own right.  Instead, the focus here will be on how git
+fits into the kernel development process in particular.  Developers who
+wish to come up to speed with git will find more information at:
+
+	http://git.or.cz/
+
+	http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+and on various tutorials found on the web.
+
+The first order of business is to read the above sites and get a solid
+understanding of how git works before trying to use it to make patches
+available to others.  A git-using developer should be able to obtain a copy
+of the mainline repository, explore the revision history, commit changes to
+the tree, use branches, etc.  An understanding of git's tools for the
+rewriting of history (such as rebase) is also useful.  Git comes with its
+own terminology and concepts; a new user of git should know about refs,
+remote branches, the index, fast-forward merges, pushes and pulls, detached
+heads, etc.  It can all be a little intimidating at the outset, but the
+concepts are not that hard to grasp with a bit of study.
+
+Using git to generate patches for submission by email can be a good
+exercise while coming up to speed.
+
+When you are ready to start putting up git trees for others to look at, you
+will, of course, need a server that can be pulled from.  Setting up such a
+server with git-daemon is relatively straightforward if you have a system
+which is accessible to the Internet.  Otherwise, free, public hosting sites
+(Github, for example) are starting to appear on the net.  Established
+developers can get an account on kernel.org, but those are not easy to come
+by; see http://kernel.org/faq/ for more information.
+
+The normal git workflow involves the use of a lot of branches.  Each line
+of development can be separated into a separate "topic branch" and
+maintained independently.  Branches in git are cheap, there is no reason to
+not make free use of them.  And, in any case, you should not do your
+development in any branch which you intend to ask others to pull from.
+Publicly-available branches should be created with care; merge in patches
+from development branches when they are in complete form and ready to go -
+not before.
+
+Git provides some powerful tools which can allow you to rewrite your
+development history.  An inconvenient patch (one which breaks bisection,
+say, or which has some other sort of obvious bug) can be fixed in place or
+made to disappear from the history entirely.  A patch series can be
+rewritten as if it had been written on top of today's mainline, even though
+you have been working on it for months.  Changes can be transparently
+shifted from one branch to another.  And so on.  Judicious use of git's
+ability to revise history can help in the creation of clean patch sets with
+fewer problems.
+
+Excessive use of this capability can lead to other problems, though, beyond
+a simple obsession for the creation of the perfect project history.
+Rewriting history will rewrite the changes contained in that history,
+turning a tested (hopefully) kernel tree into an untested one.  But, beyond
+that, developers cannot easily collaborate if they do not have a shared
+view of the project history; if you rewrite history which other developers
+have pulled into their repositories, you will make life much more difficult
+for those developers.  So a simple rule of thumb applies here: history
+which has been exported to others should generally be seen as immutable
+thereafter.
+
+So, once you push a set of changes to your publicly-available server, those
+changes should not be rewritten.  Git will attempt to enforce this rule if
+you try to push changes which do not result in a fast-forward merge
+(i.e. changes which do not share the same history).  It is possible to
+override this check, and there may be times when it is necessary to rewrite
+an exported tree.  Moving changesets between trees to avoid conflicts in
+linux-next is one example.  But such actions should be rare.  This is one
+of the reasons why development should be done in private branches (which
+can be rewritten if necessary) and only moved into public branches when
+it's in a reasonably advanced state.
+
+As the mainline (or other tree upon which a set of changes is based)
+advances, it is tempting to merge with that tree to stay on the leading
+edge.  For a private branch, rebasing can be an easy way to keep up with
+another tree, but rebasing is not an option once a tree is exported to the
+world.  Once that happens, a full merge must be done.  Merging occasionally
+makes good sense, but overly frequent merges can clutter the history
+needlessly.  Suggested technique in this case is to merge infrequently, and
+generally only at specific release points (such as a mainline -rc
+release).  If you are nervous about specific changes, you can always
+perform test merges in a private branch.  The git "rerere" tool can be
+useful in such situations; it remembers how merge conflicts were resolved
+so that you don't have to do the same work twice.
+
+One of the biggest recurring complaints about tools like git is this: the
+mass movement of patches from one repository to another makes it easy to
+slip in ill-advised changes which go into the mainline below the review
+radar.  Kernel developers tend to get unhappy when they see that kind of
+thing happening; putting up a git tree with unreviewed or off-topic patches
+can affect your ability to get trees pulled in the future.  Quoting Linus:
+
+	You can send me patches, but for me to pull a git patch from you, I
+	need to know that you know what you're doing, and I need to be able
+	to trust things *without* then having to go and check every
+	individual change by hand.
+
+(http://lwn.net/Articles/224135/).  
+
+To avoid this kind of situation, ensure that all patches within a given
+branch stick closely to the associated topic; a "driver fixes" branch
+should not be making changes to the core memory management code.  And, most
+importantly, do not use a git tree to bypass the review process.  Post an
+occasional summary of the tree to the relevant list, and, when the time is
+right, request that the tree be included in linux-next.
+
+If and when others start to send patches for inclusion into your tree,
+don't forget to review them.  Also ensure that you maintain the correct
+authorship information; the git "am" tool does its best in this regard, but
+you may have to add a "From:" line to the patch if it has been relayed to
+you via a third party.
+
+When requesting a pull, be sure to give all the relevant information: where
+your tree is, what branch to pull, and what changes will result from the
+pull.  The git request-pull command can be helpful in this regard; it will
+format the request as other developers expect, and will also check to be
+sure that you have remembered to push those changes to the public server. 
+
+
+7.2: REVIEWING PATCHES
+
+Some readers will certainly object to putting this section with "advanced
+topics" on the grounds that even beginning kernel developers should be
+reviewing patches.  It is certainly true that there is no better way to
+learn how to program in the kernel environment than by looking at code
+posted by others.  In addition, reviewers are forever in short supply; by
+looking at code you can make a significant contribution to the process as a
+whole.
+
+Reviewing code can be an intimidating prospect, especially for a new kernel
+developer who may well feel nervous about questioning code - in public -
+which has been posted by those with more experience.  Even code written by
+the most experienced developers can be improved, though.  Perhaps the best
+piece of advice for reviewers (all reviewers) is this: phrase review
+comments as questions rather than criticisms.  Asking "how does the lock
+get released in this path?" will always work better than stating "the
+locking here is wrong."
+
+Different developers will review code from different points of view.  Some
+are mostly concerned with coding style and whether code lines have trailing
+white space.  Others will focus primarily on whether the change implemented
+by the patch as a whole is a good thing for the kernel or not.  Yet others
+will check for problematic locking, excessive stack usage, possible
+security issues, duplication of code found elsewhere, adequate
+documentation, adverse effects on performance, user-space ABI changes, etc.
+All types of review, if they lead to better code going into the kernel, are
+welcome and worthwhile.

+8: FOR MORE INFORMATION
+
+There are numerous sources of information on Linux kernel development and
+related topics.  First among those will always be the Documentation
+directory found in the kernel source distribution.  The top-level HOWTO
+file is an important starting point; SubmittingPatches and
+SubmittingDrivers are also something which all kernel developers should
+read.  Many internal kernel APIs are documented using the kerneldoc
+mechanism; "make htmldocs" or "make pdfdocs" can be used to generate those
+documents in HTML or PDF format (though the version of TeX shipped by some
+distributions runs into internal limits and fails to process the documents
+properly).
+
+Various web sites discuss kernel development at all levels of detail.  Your
+author would like to humbly suggest http://lwn.net/ as a source;
+information on many specific kernel topics can be found via the LWN kernel
+index at:
+
+	http://lwn.net/Kernel/Index/
+
+Beyond that, a valuable resource for kernel developers is:
+
+	http://kernelnewbies.org/
+
+Information about the linux-next tree gathers at:
+
+	http://linux.f-seidel.de/linux-next/pmwiki/
+
+And, of course, one should not forget http://kernel.org/, the definitive
+location for kernel release information.
+
+There are a number of books on kernel development:
+
+	Linux Device Drivers, 3rd Edition (Jonathan Corbet, Alessandro
+	Rubini, and Greg Kroah-Hartman).  Online at
+	http://lwn.net/Kernel/LDD3/.
+
+	Linux Kernel Development (Robert Love).
+
+	Understanding the Linux Kernel (Daniel Bovet and Marco Cesati).
+
+All of these books suffer from a common fault, though: they tend to be
+somewhat obsolete by the time they hit the shelves, and they have been on
+the shelves for a while now.  Still, there is quite a bit of good
+information to be found there.
+
+Documentation for git can be found at:
+
+	http://www.kernel.org/pub/software/scm/git/docs/
+
+	http://www.kernel.org/pub/software/scm/git/docs/user-manual.html
+
+
+9: CONCLUSION
+
+Congratulations to anybody who has made it through this long-winded
+document.  Hopefully it has provided a helpful understanding of how the
+Linux kernel is developed and how you can participate in that process.
+
+In the end, it's the participation that matters.  Any open source software
+project is no more than the sum of what its contributors put into it.  The
+Linux kernel has progressed as quickly and as well as it has because it has
+been helped by an impressively large group of developers, all of whom are
+working to make it better.  The kernel is a premier example of what can be
+done when thousands of people work together toward a common goal.
+
+The kernel can always benefit from a larger developer base, though.  There
+is always more work to do.  But, just as importantly, most other
+participants in the Linux ecosystem can benefit through contributing to the
+kernel.  Getting code into the mainline is the key to higher code quality,
+lower maintenance and distribution costs, a higher level of influence over
+the direction of kernel development, and more.  It is a situation where
+everybody involved wins.  Fire up your editor and come join us; you will be
+more than welcome.

-        This declares our video4linux device driver interface. The VID_TYPE_ value

-  <para>
-        The only defined value relevant for a radio card is VID_TYPE_TUNER which

-  <para>
-        We declare an open and close routine, but we do not need read or write,

-        we have no read or write there is no poll function.

-        The private initialise function is run when the device is registered. In

-        The settings for the radio card are thus fairly simple. We report that we
-        are a tuner called "FM" for FM radio. In order to get the best tuning
-        resolution we report VIDEO_TUNER_LOW and select tuning to 1/16th of KHz. Its
-        unlikely our card can do that resolution but it is a fair bet the card can
-        do better than 1/16th of a MHz. VIDEO_TUNER_LOW is appropriate to almost all
-        radio usage.
-  </para>
-  <para>
-        We report that the tuner automatically handles deciding what format it is
-        receiving - true enough as it only handles FM radio. Our example card is
-        also incapable of detecting stereo or signal strengths so it reports a
-        strength of 0xFFFF (maximum) and no stereo detected.
-  </para>
-  <para>
-        To finish off we set the range that can be tuned to be 87-108Mhz, the normal
-        FM broadcast radio range. It is important to find out what the card is
-        actually capable of tuning. It is easy enough to simply use the FM broadcast
-        range. Unfortunately if you do this you will discover the FM broadcast
-        ranges in the USA, Europe and Japan are all subtly different and some users
-        cannot receive all the stations they wish.

-        Setting the frequency is a little more complex. We begin by copying the

-  <title>Video Capture Device Types</title>
-  <para>
-        The video capture devices share the same interfaces as radio devices. In
-        order to explain the video capture interface I will use the example of a
-        camera that has no tuners or audio input. This keeps the example relatively
-        clean. To get both combine the two driver examples.
-  </para>
-  <para>
-        Video capture devices divide into four categories. A little technology
-        backgrounder. Full motion video even at television resolution (which is
-        actually fairly low) is pretty resource-intensive. You are continually
-        passing megabytes of data every second from the capture card to the display. 
-        several alternative approaches have emerged because copying this through the 
-        processor and the user program is a particularly bad idea .
-  </para>
-  <para>
-        The first is to add the television image onto the video output directly.
-        This is also how some 3D cards work. These basic cards can generally drop the
-        video into any chosen rectangle of the display. Cards like this, which
-        include most mpeg1 cards that used the feature connector,  aren't very
-        friendly in a windowing environment. They don't understand windows or
-        clipping. The video window is always on the top of the display.
-  </para>
-  <para>
-        Chroma keying is a technique used by cards to get around this. It is an old
-        television mixing trick where you mark all the areas you wish to replace
-        with a single clear colour that isn't used in the image - TV people use an
-        incredibly bright blue while computing people often use a particularly
-        virulent purple. Bright blue occurs on the desktop. Anyone with virulent
-        purple windows has another problem besides their TV overlay.
-  </para>
-  <para>
-        The third approach is to copy the data from the capture card to the video
-        card, but to do it directly across the PCI bus. This relieves the processor
-        from doing the work but does require some smartness on the part of the video
-        capture chip, as well as a suitable video card. Programming this kind of
-        card and more so debugging it can be extremely tricky. There are some quite
-        complicated interactions with the display and you may also have to cope with
-        various chipset bugs that show up when PCI cards start talking to each
-        other. 
-  </para>
-  <para>
-        To keep our example fairly simple we will assume a card that supports
-        overlaying a flat rectangular image onto the frame buffer output, and which
-        can also capture stuff into processor memory.

-        We wait for a frame to be ready, or for a signal to interrupt our waiting. If a

Subject: introduce generic header file for the software IO/TLB

A series of patches introduce a generic header file for the software
IO/TLB implementation in lib/swiotlb.c.  Currently each architecture using
this code defines the prototypes itself.  The prototypes are moved to
include/linux/swiotlb.h and this file is included in architecture specific
code for X86 and IA64.

This patch:

Create include/linux/swiotlb.h file which contains all function prototypes
for the lib/swiotlb.c file.

(akpm: the dependent patches will be trickled through arch trees)

Subject: mm/page_alloc.c:free_area_init_nodes() fix inappropriate use of enum

Local variable `i' is a) misleadingly-named for an `enum zone_type' and b)
used for indexing zones as well as nodes as well as node_maps.

Make it an `int'.

Subject: hugetlb: handle updating of ACCESSED and DIRTY in hugetlb_fault()

The page fault path for normal pages, if the fault is neither a no-page
fault nor a write-protect fault, will update the DIRTY and ACCESSED bits
in the page table appropriately.

The hugepage fault path, however, does not do this, handling only no-page
or write-protect type faults.  It assumes that either the ACCESSED and
DIRTY bits are irrelevant for hugepages (usually true, since they are
never swapped) or that they are handled by the arch code.

This is inconvenient for some software-loaded TLB architectures, where the
_PAGE_ACCESSED (_PAGE_DIRTY) bits need to be set to enable read (write)
access to the page at the TLB miss.  This could be worked around in the
arch TLB miss code, but the TLB miss fast path can be made simple more
easily if the hugetlb_fault() path handles this, as the normal page fault
path does.

Subject: uclinux: fix gzip header parsing in binfmt_flat.c

There are off-by-one errors in decompress_exec() when calculating the length of
optional "original file name" and "comment" fields: the "ret" index is not
incremented when terminating '\0' character is reached. The check of the buffer
overflow (after an "extra-field" length was taken into account) is also fixed.

I've encountered this off-by-one error when tried to reuse
gzip-header-parsing part of the decompress_exec() function.  There was an
"original file name" field in the payload (with miscalculated length) and
zlib_inflate() returned Z_DATA_ERROR.  But after the fix similar to this
one all worked fine.

Date: Wed, 15 Oct 2008 22:01:21 -0700
Subject: pm: rework disabling of user mode helpers during suspend/hibernation

We currently use a PM notifier to disable user mode helpers before suspend
and hibernation and to re-enable them during resume.  However, this is not
an ideal solution, because if any drivers want to upload firmware into
memory before suspend, they have to use a PM notifier for this purpose and
there is no guarantee that the ordering of PM notifiers will be as
expected (ie.  the notifier that disables user mode helpers has to be run
after the driver's notifier used for uploading the firmware).

For this reason, it seems better to move the disabling and enabling of
user mode helpers to separate functions that will be called by the PM core
as necessary.

Subject: pm: document use of RTC in pm_trace

As pm_trace uses the system's hardware clock to save its magic value,
users of that option should be warned that using this debug option will
result in an incorrect system time after resume.

 that "radeonfb" simply cannot resume that device - it tries to set the
 PLL's, and it just _hangs_. Using the regular VGA console and letting X
 resume it instead works fine.
+
+NOTE
+====
+pm_trace uses the system's Real Time Clock (RTC) to save the magic number.
+Reason for this is that the RTC is the only reliably available piece of
+hardware during resume operations where a value can be set that will
+survive a reboot.
+
+Consequence is that after a resume (even if it is successful) your system
+clock will have a value corresponding to the magic mumber instead of the
+correct date/time! It is therefore advisable to use a program like ntp-date
+or rdate to reset the correct date/time from an external time source when
+using this trace option.
+
+As the clock keeps ticking it is also essential that the reboot is done
+quickly after the resume failure. The trace option does not use the seconds
+or the low order bits of the minutes of the RTC, but a too long delay will
+corrupt the magic value.

Subject: identify_ramdisk_image(): correct typo about return value in comment

identify_ramdisk_image() returns 0 (not -1) if a gzipped ramdisk is found:

		goto done;
	}

	...

done:
	sys_lseek(fd, start_block * BLOCK_SIZE, 0);
	kfree(buf);
	return nblocks;
	^^^^^^^^^^^^^^

Hence correct the typo in the comment, which has existed since the
addition of compressed ramdisk support in 1.3.48.

Subject: vsprintf: use new vsprintf symbolic function pointer format

Use the '%pF' format to get rid of an "#ifdef DEBUG" and make some printks
atomic.

This removes the last in-tree uses of print_fn_descriptor_symbol().  I
marked print_fn_descriptor_symbol() deprecated and scheduled it for
removal next year to give time for out-of-tree modules to be updated.

parisc's print_fn_descriptor_symbol() is currently broken there (it needs
to dereference the function pointer similar to ia64 and power).  This
patch shouldn't make anything worse, but it means we need to fix
dereference_function_descriptor() instead of print_fn_descriptor_symbol()
to get meaningful initcall_debug output.

Subject: wait: kill is_sync_wait()

is_sync_wait() is used to distinguish between sync and async waits.
Basically sync waits are the ones initialized with init_waitqueue_entry()
and async ones with init_waitqueue_func_entry().  The sync/async
distinction is used only in prepare_to_wait[_exclusive]() and its only
function is to skip setting the current task state if the wait is async.
This has a few problems.

* No one uses it.  None of func_entry users use prepare_to_wait()
  functions, so the code path never gets executed.

* The distinction is bogus.  Maybe back when func_entry is used only
  by aio but it's now also used by epoll and in future possibly by 9p
  and poll/select.

* Taking @state as argument and ignoring it silenly depending on how
  @wait is initialized is just a bad error-prone API.

* It prevents func_entry waits from using wait->private for no good
  reason.

This patch kills is_sync_wait() and the associated code paths from
prepare_to_wait[_exclusive]().  As there was no user of these code paths,
this patch doesn't cause any behavior difference.

Subject: Kconfig: eliminate "def_bool n" constructs

Using "def_bool n" is pointless, simply using bool here appears more
appropriate.

Further, retaining such options that don't have a prompt and aren't
selected by anything seems also at least questionable.

Subject: initramfs: add option to preserve mtime from initramfs cpio images

When unpacking the cpio into the initramfs, mtimes are not preserved by
default.  This patch adds an INITRAMFS_PRESERVE_MTIME option that allows
mtimes stored in the cpio image to be used when constructing the
initramfs.

For embedded applications that run exclusively out of the initramfs, this
is invaluable:

When building embedded application initramfs images, its nice to know when
the files were actually created during the build process - that makes it
easier to see what files were modified when so we can compare the files
that are being used on the image with the files used during the build
process.  This might help (for example) to determine if the target system
has all the updated files you expect to see w/o having to check MD5s etc.

In our environment, the whole system runs off the initramfs partition, and
seeing the modified times of the shared libraries (for example) helps us
find bugs that may have been introduced by the build system incorrectly
propogating outdated shared libraries into the image.

Similarly, many of the initializion/configuration files in /etc might be
dynamically built by the build system, and knowing when they were modified
helps us sanity check whether the target system has the "latest" files
etc.

Finally, we might use last modified times to determine whether a hot fix
should be applied or not to the running ramfs.

Subject: Make the taint flags reliable

It's somewhat unlikely that it happens, but right now a race window
between interrupts or machine checks or oopses could corrupt the tainted
bitmap because it is modified in a non atomic fashion.

Convert the taint variable to an unsigned long and use only atomic bit
operations on it.

Unfortunately this means the intvec sysctl functions cannot be used on it
anymore.

It turned out the taint sysctl handler could actually be simplified a bit
(since it only increases capabilities) so this patch actually removes
code.

It is written in the Documentation/sysrq.txt that oom-killer is enabled
when we set "64" in /proc/sys/kernel/sysrq:

<Documentation/sysrq.txt>

    Here is the list of possible values in /proc/sys/kernel/sysrq:
         64 - enable signalling of processes (term, kill, oom-kill)
                                                          ^^^^^^^^

but enable_mask is not set in sysrq_moom_op.

Subject: rlimit: permit setting RLIMIT_NOFILE to RLIM_INFINITY

When a process wants to set the limit of open files to RLIM_INFINITY it
gets EPERM even if it has CAP_SYS_RESOURCE capability.

For example, BIND does:

...
#elif defined(NR_OPEN) && defined(__linux__)
        /*
         * Some Linux kernels don't accept RLIM_INFINIT; the maximum
         * possible value is the NR_OPEN defined in linux/fs.h.
         */
        if (resource == isc_resource_openfiles && rlim_value == RLIM_INFINITY) {
                rl.rlim_cur = rl.rlim_max = NR_OPEN;
                unixresult = setrlimit(unixresource, &rl);
                if (unixresult == 0)
                        return (ISC_R_SUCCESS);
        }
#elif ...

If we allow setting RLIMIT_NOFILE to RLIM_INFINITY we increase portability
- you don't have to check if OS is linux and then use different schema for
limits.

The spec says "Specifying RLIM_INFINITY as any resource limit value on a
successful call to setrlimit() shall inhibit enforcement of that resource
limit." and we're presently not doing that.

Subject: profiling: dynamically enable readprofile at runtime

Way too often, I have a machine that exhibits some kind of crappy
behavior.  The CPU looks wedged in the kernel or it is spending way too
much system time and I wonder what is responsible.

I try to run readprofile.  But, of course, Ubuntu doesn't enable it by
default.  Dang!

The reason we boot-time enable it is that it takes a big bufffer that we
generally can only bootmem alloc.  But, does it hurt to at least try and
runtime-alloc it?

To use:
echo 2 > /sys/kernel/profile

Then run readprofile like normal.

This should fix the compile issue with allmodconfig.  I've compile-tested
on a bunch more configs now including a few more architectures.

Subject: utsname: completely overwrite prior information

On sethostname() and setdomainname(), previous information may be retained
if it was longer than than the new hostname/domainname.

This can be demonstrated trivially by calling sethostname() first with a
long name, then with a short name, and then calling uname() to retrieve
the full buffer that contains the hostname (and possibly parts of the old
hostname), one just has to look past the terminating zero.

I don't know if we should really care that much (hence the RFC); the only
scenarios I can possibly think of is administrator putting something
sensitive in the hostname (or domain name) by accident, and changing it
back will not undo the mistake entirely, though it's not like we can
recover gracefully from "rm -rf /" either...  The other scenario is
namespaces (CLONE_NEWUTS) where some information may be unintentionally
"inherited" from the previous namespace (a program wants to hide the
original name and does clone + sethostname, but some information is still
left).

I think the patch may be defended on grounds of the principle of least
surprise.  But I am not adamant :-)

(I guess the question now is whether userspace should be able to
write embedded NULs into the buffer or not...)

At least the observation has been made and the patch has been presented.

Subject: exec.c, compat.c: fix count(), compat_count() bounds checking

With MAX_ARG_STRINGS set to 0x7FFFFFFF, and being passed to 'count()' and
compat_count(), it would appear that the current max bounds check of
fs/exec.c:394:

	if(++i > max)
		return -E2BIG;

would never trigger. Since 'i' is of type int, so values would wrap and the
function would continue looping.

Simple fix seems to be chaning ++i to i++ and checking for '>='.

Thomas found that there is an unnecessary (always true) test in
ep_send_events().  The callback never inserts into ->rdllink while the
send loop is performed, and also does the ~EP_PRIVATE_BITS test.  Given
we're holding the mutex during this time, the conditions tested inside the
loop are always true.  This patch drops the test done inside the
re-insertion loop.

Subject: compat: move cp_compat_stat to common code

struct stat / compat_stat is the same on all architectures, so
cp_compat_stat should be, too.

Turns out it is, except that various architectures have slightly and some
high2lowuid/high2lowgid or the direct assignment instead of the
SET_UID/SET_GID that expands to the correct one anyway.

This patch replaces the arch-specific cp_compat_stat implementations with
a common one based on the x86-64 one.

From b418da16dd44810e5d5a22bba377cca80512a524 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>
Date: Wed, 15 Oct 2008 22:02:06 -0700
Subject: compat: generic compat get/settimeofday

Nothing arch specific in get/settimeofday.  The details of the timeval
conversion varied a little from arch to arch, but all with the same
results.

Also add an extern declaration for sys_tz to linux/time.h because externs
in .c files are fowned upon.  I'll kill the externs in various other files
in a sparate patch.

From bdab0ba3d9ad8de257ee6236daf314723748fde6 Mon Sep 17 00:00:00 2001
From: Joerg Roedel <joerg.roedel@amd.com>
Date: Wed, 15 Oct 2008 22:02:07 -0700
Subject: x86: rename iommu_num_pages function to iommu_nr_pages

This series of patches re-introduces the iommu_num_pages function so that
it can be used by each architecture specific IOMMU implementations.  The
series also changes IOMMU implementations for X86, Alpha, PowerPC and
UltraSparc.  The other implementations are not yet changed because the
modifications required are not obvious and I can't test them on real
hardware.

This patch:

This is a preparation patch for introducing a generic iommu_num_pages function.

It is a common and sane idiom to allow a single return on the end of a
case statement:

	switch (...) {
	case foo:	return bar;
	}

Add an exception for this.

referencing file is in the arch directory.

Subject: checkpatch: report the real first line of all suspect indents

We are currently only reporting syspect indents if the conditional is
modified but the indent missmatch could be generated by the body changing,
make sure we catch both.  Also only report the first line of the body, and
more importantly make sure we report the raw copy of the line.  Finally
report the indent levels to make it easier to understand what is wrong.

We should skip over and check the lines which follow preprocessor
statements, labels, and blank lines.  These all have legitimate reasons to
be indented differently.

A do without braces '{' may trigger a false possible type 'do' and then
this may be interpreted as an external definition of foo():

Add do to the type exclusions.  Fix up tests so we can check for them.

Subject: checkpatch: macros which define structure members are not complex

We often see macros which define structure members, these are not complex
and necessarily do not have braces or brackets.  For example:

    #define _PLIST_HEAD_INIT(head)                      \
        .prio_list = LIST_HEAD_INIT((head).prio_list),  \
        .node_list = LIST_HEAD_INIT((head).node_list)

that line too with an appropriate gap marker where applicable.

Subject: Allow recursion in binfmt_script and binfmt_misc

binfmt_script and binfmt_misc disallow recursion to avoid stack overflow
using sh_bang and misc_bang.  It causes problem in some cases:

$ echo '#!/bin/ls' > /tmp/t0
$ echo '#!/tmp/t0' > /tmp/t1
$ echo '#!/tmp/t1' > /tmp/t2
$ chmod +x /tmp/t*
$ /tmp/t2
zsh: exec format error: /tmp/t2

Similar problem with binfmt_misc.

This patch introduces field 'recursion_depth' into struct linux_binprm to
track recursion level in binfmt_misc and binfmt_script.  If recursion
level more then BINPRM_MAX_RECURSION it generates -ENOEXEC.

Subject: spi_s3c24xx: pin configuration updates

Add a pin configuration callback for the s3c24xx SPI driver, as there are
several options depending on the channel and the chip in use.

This is needed as the controller may not have been setup by the initial
bootloader and the fact that the SPI controller gets reset over
suspend/resume into slave mode but the GPIO function registers do not.

Subject: pxa2xx_spi: fix chip_info defaults and documentation.

Make the chip info structure data optional by providing reasonable
defaults.  Improve corresponding documentation, and highlight the drawback
of not providing explicit chipselect control.

DMA can determine appropriate dma_burst_size and thresholds automatically
so use DMA even if dma_burst_size is not specified.

Subject: spi: core and gpio expanders use subsys_init

Make the SPI external GPIO expander drivers register themselves at
subsys_initcall() time when they're statically linked, and make the SPI
core do its driver model initialization earlier so that's safe.

SOC-integrated GPIOs are available starting very early -- often before
initcalls start to run, or earily in arch_initcall() at latest -- so this
improves consistency, letting more subsystems rely on GPIOs being usable
by their own subsys_initcall() code.

Subject: i2o: Fix 32/64bit DMA locking

The I2O ioctls assume 32bits.  In itself that is fine as they are old
cards and nobody uses 64bit.  However on LKML it was noted this
assumption is also made for allocated memory and is unsafe on 64bit
systems.

Fixing this is a mess.  It turns out there is tons of crap buried in a
header file that does racy 32/64bit filtering on the masks.

So we:
- Verify all callers of the racy code can sleep (i2o_dma_[re]alloc)
- Move the code into a new i2o/memory.c file
- Remove the gfp_mask argument so nobody can try and misuse the function
- Wrap a mutex around the problem area (a single mutex is easy to do and
  none of this is performance relevant)
- Switch the remaining problem kmalloc holdout to use i2o_dma_alloc

Subject: eCryptfs: remove retry loop in ecryptfs_readdir()

The retry block in ecryptfs_readdir() has been in the eCryptfs code base
for a while, apparently for no good reason.  This loop could potentially
run without terminating.  This patch removes the loop, instead erroring
out if vfs_readdir() on the lower file fails.

From: Tyler Hicks <tyhicks@linux.vnet.ibm.com>

Subject: eCryptfs: remove netlink transport

The netlink transport code has not worked for a while and the miscdev
transport is a simpler solution.  This patch removes the netlink code and
makes the miscdev transport the only eCryptfs kernel to userspace
transport.

+
+Miscellaneous Device control operations for the autofs4 kernel module
+====================================================================
+
+The problem
+===========
+
+There is a problem with active restarts in autofs (that is to say
+restarting autofs when there are busy mounts).
+
+During normal operation autofs uses a file descriptor opened on the
+directory that is being managed in order to be able to issue control
+operations. Using a file descriptor gives ioctl operations access to
+autofs specific information stored in the super block. The operations
+are things such as setting an autofs mount catatonic, setting the
+expire timeout and requesting expire checks. As is explained below,
+certain types of autofs triggered mounts can end up covering an autofs
+mount itself which prevents us being able to use open(2) to obtain a
+file descriptor for these operations if we don't already have one open.
+
+Currently autofs uses "umount -l" (lazy umount) to clear active mounts
+at restart. While using lazy umount works for most cases, anything that
+needs to walk back up the mount tree to construct a path, such as
+getcwd(2) and the proc file system /proc/<pid>/cwd, no longer works
+because the point from which the path is constructed has been detached
+from the mount tree.
+
+The actual problem with autofs is that it can't reconnect to existing
+mounts. Immediately one thinks of just adding the ability to remount
+autofs file systems would solve it, but alas, that can't work. This is
+because autofs direct mounts and the implementation of "on demand mount
+and expire" of nested mount trees have the file system mounted directly
+on top of the mount trigger directory dentry.
+
+For example, there are two types of automount maps, direct (in the kernel
+module source you will see a third type called an offset, which is just
+a direct mount in disguise) and indirect.
+
+Here is a master map with direct and indirect map entries:
+
+/-      /etc/auto.direct
+/test   /etc/auto.indirect
+
+and the corresponding map files:
+
+/etc/auto.direct:
+
+/automount/dparse/g6  budgie:/autofs/export1
+/automount/dparse/g1  shark:/autofs/export1
+and so on.
+
+/etc/auto.indirect:
+
+g1    shark:/autofs/export1
+g6    budgie:/autofs/export1
+and so on.
+
+For the above indirect map an autofs file system is mounted on /test and
+mounts are triggered for each sub-directory key by the inode lookup
+operation. So we see a mount of shark:/autofs/export1 on /test/g1, for
+example.
+
+The way that direct mounts are handled is by making an autofs mount on
+each full path, such as /automount/dparse/g1, and using it as a mount
+trigger. So when we walk on the path we mount shark:/autofs/export1 "on
+top of this mount point". Since these are always directories we can
+use the follow_link inode operation to trigger the mount.
+
+But, each entry in direct and indirect maps can have offsets (making
+them multi-mount map entries).
+
+For example, an indirect mount map entry could also be:
+
+g1  \
+   /        shark:/autofs/export5/testing/test \
+   /s1      shark:/autofs/export/testing/test/s1 \
+   /s2      shark:/autofs/export5/testing/test/s2 \
+   /s1/ss1  shark:/autofs/export1 \
+   /s2/ss2  shark:/autofs/export2
+
+and a similarly a direct mount map entry could also be:
+
+/automount/dparse/g1 \
+    /       shark:/autofs/export5/testing/test \
+    /s1     shark:/autofs/export/testing/test/s1 \
+    /s2     shark:/autofs/export5/testing/test/s2 \
+    /s1/ss1 shark:/autofs/export2 \
+    /s2/ss2 shark:/autofs/export2
+
+One of the issues with version 4 of autofs was that, when mounting an
+entry with a large number of offsets, possibly with nesting, we needed
+to mount and umount all of the offsets as a single unit. Not really a
+problem, except for people with a large number of offsets in map entries.
+This mechanism is used for the well known "hosts" map and we have seen
+cases (in 2.4) where the available number of mounts are exhausted or
+where the number of privileged ports available is exhausted.
+
+In version 5 we mount only as we go down the tree of offsets and
+similarly for expiring them which resolves the above problem. There is
+somewhat more detail to the implementation but it isn't needed for the
+sake of the problem explanation. The one important detail is that these
+offsets are implemented using the same mechanism as the direct mounts
+above and so the mount points can be covered by a mount.
+
+The current autofs implementation uses an ioctl file descriptor opened
+on the mount point for control operations. The references held by the
+descriptor are accounted for in checks made to determine if a mount is
+in use and is also used to access autofs file system information held
+in the mount super block. So the use of a file handle needs to be
+retained.
+
+
+The Solution
+============
+
+To be able to restart autofs leaving existing direct, indirect and
+offset mounts in place we need to be able to obtain a file handle
+for these potentially covered autofs mount points. Rather than just
+implement an isolated operation it was decided to re-implement the
+existing ioctl interface and add new operations to provide this
+functionality.
+
+In addition, to be able to reconstruct a mount tree that has busy mounts,
+the uid and gid of the last user that triggered the mount needs to be
+available because these can be used as macro substitution variables in
+autofs maps. They are recorded at mount request time and an operation
+has been added to retrieve them.
+
+Since we're re-implementing the control interface, a couple of other
+problems with the existing interface have been addressed. First, when
+a mount or expire operation completes a status is returned to the
+kernel by either a "send ready" or a "send fail" operation. The
+"send fail" operation of the ioctl interface could only ever send
+ENOENT so the re-implementation allows user space to send an actual
+status. Another expensive operation in user space, for those using
+very large maps, is discovering if a mount is present. Usually this
+involves scanning /proc/mounts and since it needs to be done quite
+often it can introduce significant overhead when there are many entries
+in the mount table. An operation to lookup the mount status of a mount
+point dentry (covered or not) has also been added.
+
+Current kernel development policy recommends avoiding the use of the
+ioctl mechanism in favor of systems such as Netlink. An implementation
+using this system was attempted to evaluate its suitability and it was
+found to be inadequate, in this case. The Generic Netlink system was
+used for this as raw Netlink would lead to a significant increase in
+complexity. There's no question that the Generic Netlink system is an
+elegant solution for common case ioctl functions but it's not a complete
+replacement probably because it's primary purpose in life is to be a
+message bus implementation rather than specifically an ioctl replacement.
+While it would be possible to work around this there is one concern
+that lead to the decision to not use it. This is that the autofs
+expire in the daemon has become far to complex because umount
+candidates are enumerated, almost for no other reason than to "count"
+the number of times to call the expire ioctl. This involves scanning
+the mount table which has proved to be a big overhead for users with
+large maps. The best way to improve this is try and get back to the
+way the expire was done long ago. That is, when an expire request is
+issued for a mount (file handle) we should continually call back to
+the daemon until we can't umount any more mounts, then return the
+appropriate status to the daemon. At the moment we just expire one
+mount at a time. A Generic Netlink implementation would exclude this
+possibility for future development due to the requirements of the
+message bus architecture.
+
+
+autofs4 Miscellaneous Device mount control interface
+====================================================
+
+The control interface is opening a device node, typically /dev/autofs.
+
+All the ioctls use a common structure to pass the needed parameter
+information and return operation results:
+
+struct autofs_dev_ioctl {
+	__u32 ver_major;
+	__u32 ver_minor;
+	__u32 size;             /* total size of data passed in
+				 * including this struct */
+	__s32 ioctlfd;          /* automount command fd */
+
+	__u32 arg1;             /* Command parameters */
+	__u32 arg2;
+
+	char path[0];
+};
+
+The ioctlfd field is a mount point file descriptor of an autofs mount
+point. It is returned by the open call and is used by all calls except
+the check for whether a given path is a mount point, where it may
+optionally be used to check a specific mount corresponding to a given
+mount point file descriptor, and when requesting the uid and gid of the
+last successful mount on a directory within the autofs file system.
+
+The fields arg1 and arg2 are used to communicate parameters and results of
+calls made as described below.
+
+The path field is used to pass a path where it is needed and the size field
+is used account for the increased structure length when translating the
+structure sent from user space.
+
+This structure can be initialized before setting specific fields by using
+the void function call init_autofs_dev_ioctl(struct autofs_dev_ioctl *).
+
+All of the ioctls perform a copy of this structure from user space to
+kernel space and return -EINVAL if the size parameter is smaller than
+the structure size itself, -ENOMEM if the kernel memory allocation fails
+or -EFAULT if the copy itself fails. Other checks include a version check
+of the compiled in user space version against the module version and a
+mismatch results in a -EINVAL return. If the size field is greater than
+the structure size then a path is assumed to be present and is checked to
+ensure it begins with a "/" and is NULL terminated, otherwise -EINVAL is
+returned. Following these checks, for all ioctl commands except
+AUTOFS_DEV_IOCTL_VERSION_CMD, AUTOFS_DEV_IOCTL_OPENMOUNT_CMD and
+AUTOFS_DEV_IOCTL_CLOSEMOUNT_CMD the ioctlfd is validated and if it is
+not a valid descriptor or doesn't correspond to an autofs mount point
+an error of -EBADF, -ENOTTY or -EINVAL (not an autofs descriptor) is
+returned.
+
+
+The ioctls
+==========
+
+An example of an implementation which uses this interface can be seen
+in autofs version 5.0.4 and later in file lib/dev-ioctl-lib.c of the
+distribution tar available for download from kernel.org in directory
+/pub/linux/daemons/autofs/v5.
+
+The device node ioctl operations implemented by this interface are:
+
+
+AUTOFS_DEV_IOCTL_VERSION
+------------------------
+
+Get the major and minor version of the autofs4 device ioctl kernel module
+implementation. It requires an initialized struct autofs_dev_ioctl as an
+input parameter and sets the version information in the passed in structure.
+It returns 0 on success or the error -EINVAL if a version mismatch is
+detected.
+
+
+AUTOFS_DEV_IOCTL_PROTOVER_CMD and AUTOFS_DEV_IOCTL_PROTOSUBVER_CMD
+------------------------------------------------------------------
+
+Get the major and minor version of the autofs4 protocol version understood
+by loaded module. This call requires an initialized struct autofs_dev_ioctl
+with the ioctlfd field set to a valid autofs mount point descriptor
+and sets the requested version number in structure field arg1. These
+commands return 0 on success or one of the negative error codes if
+validation fails.
+
+
+AUTOFS_DEV_IOCTL_OPENMOUNT and AUTOFS_DEV_IOCTL_CLOSEMOUNT
+----------------------------------------------------------
+
+Obtain and release a file descriptor for an autofs managed mount point
+path. The open call requires an initialized struct autofs_dev_ioctl with
+the the path field set and the size field adjusted appropriately as well
+as the arg1 field set to the device number of the autofs mount. The
+device number can be obtained from the mount options shown in
+/proc/mounts. The close call requires an initialized struct
+autofs_dev_ioct with the ioctlfd field set to the descriptor obtained
+from the open call. The release of the file descriptor can also be done
+with close(2) so any open descriptors will also be closed at process exit.
+The close call is included in the implemented operations largely for
+completeness and to provide for a consistent user space implementation.
+
+
+AUTOFS_DEV_IOCTL_READY_CMD and AUTOFS_DEV_IOCTL_FAIL_CMD
+--------------------------------------------------------
+
+Return mount and expire result status from user space to the kernel.
+Both of these calls require an initialized struct autofs_dev_ioctl
+with the ioctlfd field set to the descriptor obtained from the open
+call and the arg1 field set to the wait queue token number, received
+by user space in the foregoing mount or expire request. The arg2 field
+is set to the status to be returned. For the ready call this is always
+0 and for the fail call it is set to the errno of the operation.
+
+
+AUTOFS_DEV_IOCTL_SETPIPEFD_CMD
+------------------------------
+
+Set the pipe file descriptor used for kernel communication to the daemon.
+Normally this is set at mount time using an option but when reconnecting
+to a existing mount we need to use this to tell the autofs mount about
+the new kernel pipe descriptor. In order to protect mounts against
+incorrectly setting the pipe descriptor we also require that the autofs
+mount be catatonic (see next call).
+
+The call requires an initialized struct autofs_dev_ioctl with the
+ioctlfd field set to the descriptor obtained from the open call and
+the arg1 field set to descriptor of the pipe. On success the call
+also sets the process group id used to identify the controlling process
+(eg. the owning automount(8) daemon) to the process group of the caller.
+
+
+AUTOFS_DEV_IOCTL_CATATONIC_CMD
+------------------------------
+
+Make the autofs mount point catatonic. The autofs mount will no longer
+issue mount requests, the kernel communication pipe descriptor is released
+and any remaining waits in the queue released.
+
+The call requires an initialized struct autofs_dev_ioctl with the
+ioctlfd field set to the descriptor obtained from the open call.
+
+
+AUTOFS_DEV_IOCTL_TIMEOUT_CMD
+----------------------------
+
+Set the expire timeout for mounts withing an autofs mount point.
+
+The call requires an initialized struct autofs_dev_ioctl with the
+ioctlfd field set to the descriptor obtained from the open call.
+
+
+AUTOFS_DEV_IOCTL_REQUESTER_CMD
+------------------------------
+
+Return the uid and gid of the last process to successfully trigger a the
+mount on the given path dentry.
+
+The call requires an initialized struct autofs_dev_ioctl with the path
+field set to the mount point in question and the size field adjusted
+appropriately as well as the arg1 field set to the device number of the
+containing autofs mount. Upon return the struct field arg1 contains the
+uid and arg2 the gid.
+
+When reconstructing an autofs mount tree with active mounts we need to
+re-connect to mounts that may have used the original process uid and
+gid (or string variations of them) for mount lookups within the map entry.
+This call provides the ability to obtain this uid and gid so they may be
+used by user space for the mount map lookups.
+
+
+AUTOFS_DEV_IOCTL_EXPIRE_CMD
+---------------------------
+
+Issue an expire request to the kernel for an autofs mount. Typically
+this ioctl is called until no further expire candidates are found.
+
+The call requires an initialized struct autofs_dev_ioctl with the
+ioctlfd field set to the descriptor obtained from the open call. In
+addition an immediate expire, independent of the mount timeout, can be
+requested by setting the arg1 field to 1. If no expire candidates can
+be found the ioctl returns -1 with errno set to EAGAIN.
+
+This call causes the kernel module to check the mount corresponding
+to the given ioctlfd for mounts that can be expired, issues an expire
+request back to the daemon and waits for completion.
+
+AUTOFS_DEV_IOCTL_ASKUMOUNT_CMD
+------------------------------
+
+Checks if an autofs mount point is in use.
+
+The call requires an initialized struct autofs_dev_ioctl with the
+ioctlfd field set to the descriptor obtained from the open call and
+it returns the result in the arg1 field, 1 for busy and 0 otherwise.
+
+
+AUTOFS_DEV_IOCTL_ISMOUNTPOINT_CMD
+---------------------------------
+
+Check if the given path is a mountpoint.
+
+The call requires an initialized struct autofs_dev_ioctl. There are two
+possible variations. Both use the path field set to the path of the mount
+point to check and the size field adjusted appropriately. One uses the
+ioctlfd field to identify a specific mount point to check while the other
+variation uses the path and optionaly arg1 set to an autofs mount type.
+The call returns 1 if this is a mount point and sets arg1 to the device
+number of the mount and field arg2 to the relevant super block magic
+number (described below) or 0 if it isn't a mountpoint. In both cases
+the the device number (as returned by new_encode_dev()) is returned
+in field arg1.
+
+If supplied with a file descriptor we're looking for a specific mount,
+not necessarily at the top of the mounted stack. In this case the path
+the descriptor corresponds to is considered a mountpoint if it is itself
+a mountpoint or contains a mount, such as a multi-mount without a root
+mount. In this case we return 1 if the descriptor corresponds to a mount
+point and and also returns the super magic of the covering mount if there
+is one or 0 if it isn't a mountpoint.
+
+If a path is supplied (and the ioctlfd field is set to -1) then the path
+is looked up and is checked to see if it is the root of a mount. If a
+type is also given we are looking for a particular autofs mount and if
+a match isn't found a fail is returned. If the the located path is the
+root of a mount 1 is returned along with the super magic of the mount
+or 0 otherwise.

Subject: autofs4: add miscellaneous device for ioctls

Add a miscellaneous device to the autofs4 module for routing ioctls.  This
provides the ability to obtain an ioctl file handle for an autofs mount
point that is possibly covered by another mount.

The actual problem with autofs is that it can't reconnect to existing
mounts.  Immediately one things of just adding the ability to remount
autofs file systems would solve it, but alas, that can't work.  This is
because autofs direct mounts and the implementation of "on demand mount
and expire" of nested mount trees have the file system mounted on top of
the mount trigger dentry.

To resolve this a miscellaneous device node for routing ioctl commands to
these mount points has been implemented in the autofs4 kernel module and a
library added to autofs.  This provides the ability to open a file
descriptor for these over mounted autofs mount points.

Please refer to Documentation/filesystems/autofs4-mount-control.txt for a
discussion of the problem, implementation alternatives considered and a
description of the interface.

Subject: rtc-pcf8563: remove client validation

Validating clients with black magic register checks doesn't make much
sense for new-style i2c driver and has been known to fail on valid NXP
pcf8563 chips.  This patch removes the client validation code.

From cb49a5e9ee4fb0ab6a84a29c4de6c1bd112d38df Mon Sep 17 00:00:00 2001

Subject: rtc-ds1307: alarm support for ds1337/ds1339

Update the ds1307 driver with alarm support for ds1337/ds1339.  This uses
the first alarm (there are two), and matches on seconds, minutes, hours,
and day-of-month.  Tested on ds1339.

[dbrownell@users.sourceforge.net: add comments; fixup style, valid irq
checks, debug dumps; lock; more careful IRQ shutdown; switch BCD2BIN to
bcd2bin (and vice versa); ENOTTY not EINVAL.]

Subject: legacy rtc: remove needless/confusing HPET_RTC_IRQ option

HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more
correct.  (http://bugzilla.kernel.org/show_bug.cgi?id=11111)

Note that when using the legacy RTC driver, platforms don't really do a
dynamic switch between HPET and non-HPET modes based on whether HPET
hardware actually exists ...  only rtc-cmos (using the new RTC framework)
currently switches that way.

So this reflects bitrot in that legacy code, for x86/ia64: kernels with
HPET support configured (e.g.  for a clocksource) can't get IRQs from the
legacy RTC driver unless they really have HPET hardware.  (The obvious
workaround is to not use the legacy RTC driver on those platforms when you
configure HPET ...  unless you know the target really has a HPET.)

Subject: rtc: rtc-rs5c372: SMBus conversion/support

rtc-rs5c372 presently depends on I2C master mode transfers, despite the
fact that these RTCs frequently find themselves on SMBus-only adapters.

Given that the only capabilities that were checked were for I2C_FUNC_I2C,
it's assumed that most of the adapters that are currently using this
driver are fairly sane, and are able to handle SMBus emulation (though we
adjust the default capabilities to check for I2C_FUNC_SMBUS_EMUL anyways,
which is the vast majority of them.  The adapters that don't have their
own ->smbus_xfer() fall back on the ->master_xfer() through the emulated
transfer).

The special case is iop3xx, which has more than its fair share of hacks
within this driver, it remains untested -- though also claims to support
emulated SMBus accesses.  The corner case there is rs5c_get_regs() which
uses access mode #3 for transferring the register state, while we use mode
#1 for SMBus.

Subject: rtc: rtc-rs5c372: add support for Ricoh R2025S/D RTC

This adds support for the Ricoh R2025S/D series of I2C RTCs, produced by
Ricoh Japan and described at:

	http://www.ricoh.co.jp/LSI/product_rtc/2wire/r2025x/

This series has very minor deviations from the rest of the RS5C chips,
most of which have to do with the oscillator, which was abstracted away in
an earlier patch.

Subject: rtc: file close() consistently disables repeating irqs

Make the rtc framework consistent about disabling 1/second update IRQs
that may have been activated through the /dev interface, when that /dev
file is closed.  (It may have closed because of coredump, etc.) This was
previously done only for emulated update IRQs ...  now, do it always.

Also comment the current policy: repeating IRQs (periodic, update) that
userspace enabled will be cleanly disabled, but alarms are left alone.
Such repeating IRQs are a constant and pointless system load.

Update some RTC drivers to remove now-needless release() methods.  Most
such methods just enforce that policy.  The others all seem to be buggy,
and mistreat in-kernel clients of periodic or alarm IRQs.

Subject: rtc: rtc-m41t80.c: add support for the ST M41T65 RTC

Add support for M41T65 Real Time Clock chip.

The main differences I see between the M41T65 and M41T80 are that:

1) The M41T65 watchdog timer has three bits controlling resolution
   (versus two for the M41T80).

2) There is no register 0x13 for controlling square-wave output.

Subject: rtc-at91rm9200: remove now-unneeded code

The non-functional periodic IRQ support was previously removed from the
AT91RM9200 RTC driver.  Remove the remaining AT91_RTC_FREQ definition.

Subject: gpio: max7301: fix the race between chip addition and pins
 reconfiguration

There is a small race and code ugliness in max7301: pins are reconfigured
after the chip is registered.  Swap these calls so that the device is
registered in correct state.

Also this fixes the comile-time warning about unchecked gpiochip_remove.

Subject: gpio_free might sleep, generic part
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to the documentation gpio_free should only be called from task
context only.  To make this more explicit add a might sleep to all
implementations.

This is the generic part which changes gpiolib and the fallback
implementation only.

Subject: gpio: i2c expanders use subsys_init

Make the I2C external GPIO expander drivers register themselves at
subsys_initcall() time when they're statically linked.

SOC-integrated GPIOs are available starting very early -- early in
arch_initcall() at latest, but often even before initcalls start to run --
so this improves consistency, so more subsystems can rely on GPIOs in
their own subsys_initcall() code.

(This isn't a theoretical problem.  This is one of several patches needed
to resolve oopsing observed when statically linking kernels on a DaVinci
EVM.  Its pcf857x GPIOs needed to be available well before some other
drivers initialized.)

Subject: gpiolib: gpio_to_irq() hooks

Add a new gpiolib mechanism: gpio_chip instances can provide mappings
between their (input) GPIOs and any associated IRQs.  This makes it easier
for platforms to support IRQs that are provided by board-specific external
chips instead of as part of their core (such as SOC-integrated GPIOs).

Also update the irq_to_gpio() description, saying to avoid it because it's
not always supported.

Subject: omap drivers: switch to standard GPIO calls

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.

This is all fairly brainless/obvious stuff.  Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads.  (That would improve
with hardware IRQ debouncing enabled, of course...)

From: David Brownell <dbrownell@users.sourceforge.net>

Subject: gpiolib: request/free hooks

Add a new internal mechanism to gpiolib to support low power
operations by letting gpio_chip instances see when their GPIOs
are in use.  When no GPIOs are active, chips may be able to
enter lower powered runtime states by disabling clocks and/or
power domains.

Subject: radeonfb: revert "Fix radeon DDC regression"

The bug was in fb_ddc and was fixed by commit
b64d70825abbf706bbe80be1b11b09514b71f45e (fb_ddc: fix DDC lines quirk) so
the workaround in radeonfb can be removed now.

+        720x480
+        800x600

+
+    viafb_refresh1: (secondary display device)
+        60, 75, 85, 100, 120 (default:60)
+
+    viafb_active_dev:
+        This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
+        DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
+        set viafb_active_dev=DVI. In SAMM case, the previous of
+        viafb_active_dev is primary device, and the following is
+        secondary device.
+
+        For example:
+        To enable one device, such as DVI only, we can use:
+            modprobe viafb viafb_active_dev=DVI
+        To enable two devices, such as CRT+DVI:
+            modprobe viafb viafb_active_dev=CRT+DVI;
+
+        For DuoView case, we can use:
+            modprobe viafb viafb_active_dev=CRT+DVI
+            OR
+            modprobe viafb viafb_active_dev=DVI+CRT...
+
+        For SAMM case:
+        If CRT is primary and DVI is secondary, we should use:
+            modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
+        If DVI is primary and CRT is secondary, we should use:
+            modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
+
+    viafb_display_hardware_layout:
+        This option is used to specify display hardware layout for CX700 chip.
+        1 : LCD only
+        2 : DVI only
+        3 : LCD+DVI (default)
+        4 : LCD1+LCD2 (internal + internal)
+        16: LCD1+ExternalLCD2 (internal + external)
+
+    viafb_second_size:
+        This option is used to set second device memory size(MB) in SAMM case.
+        The minimal size is 16.
+
+    viafb_platform_epia_dvi:
+        This option is used to enable DVI on EPIA - M
+        0 : No DVI on EPIA - M (default)
+        1 : DVI on EPIA - M
+
+    viafb_bus_width:
+        When using 24 - Bit Bus Width Digital Interface,
+        this option should be set.
+        12: 12-Bit LVDS or 12-Bit TMDS (default)
+        24: 24-Bit LVDS or 24-Bit TMDS
+
+    viafb_device_lcd_dualedge:
+        When using Dual Edge Panel, this option should be set.
+        0 : No Dual Edge Panel (default)
+        1 : Dual Edge Panel
+
+    viafb_video_dev:
+        This option is used to specify video output devices(CRT, DVI, LCD) for
+        duoview case.
+        For example:
+        To output video on DVI, we should use:
+            modprobe viafb viafb_video_dev=DVI...
+
+    viafb_lcd_port:
+        This option is used to specify LCD output port,
+        available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
+        for external LCD + external DVI on CX700(External LCD is on DVP0),
+        we should use:
+            modprobe viafb viafb_lcd_port=DVP0...
+
+Notes:
+    1. CRT may not display properly for DuoView CRT & DVI display at
+       the "640x480" PAL mode with DVI overscan enabled.
+    2. SAMM stands for single adapter multi monitors. It is different from
+       multi-head since SAMM support multi monitor at driver layers, thus fbcon
+       layer doesn't even know about it; SAMM's second screen doesn't have a
+       device node file, thus a user mode application can't access it directly.
+       When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
+       viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
+    3. When console is depending on viafbinfo1, dynamically change resolution
+       and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
+       instead of calling common ioctl function FBIOPUT_VSCREENINFO since
+       viafb doesn't support multi-head well, or it will cause screen crush.
+    4. VX800 2D accelerator hasn't been supported in this driver yet. When
+       using driver on VX800, the driver will disable the acceleration
+       function as default.
+
+
+[Configure viafb with "fbset" tool]
+-----------------------------------
+    "fbset" is an inbox utility of Linux.
+    1. Inquire current viafb information, type,
+           # fbset -i
+
+    2. Set various resolutions and viafb_refresh rates,
+           # fbset <resolution-vertical_sync>
+
+       example,
+           # fbset "1024x768-75"
+       or
+           # fbset -g 1024 768 1024 768 32
+       Check the file "/etc/fb.modes" to find display modes available.
+
+    3. Set the color depth,
+           # fbset -depth <value>
+
+       example,
+           # fbset -depth 16
+
+[Bootup with viafb]:
+--------------------
+    Add the following line to your grub.conf:
+    append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
+

From b3a45d8e5d9049c3a47b3f97405b4123bef5155b Mon Sep 17 00:00:00 2001
From: Joseph Chan <JosephChan@via.com.tw>
Date: Wed, 15 Oct 2008 22:03:29 -0700
Subject: viafb: viafbdev.c (update)

Remove the macro MMIO_OUT32, and replace it with writel() function.
And replace "u32" with "unsigned long" in writel() function (original
MMIO_OUT32 marco) for avoiding warning message in 64bit OS.

Subject: intelfb: support 945GME (as used in ASUS Eee 901)

Add support for Intel's 945GME graphics chip to the intelfb driver.  I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.

The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS.  I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.

Subject: cirrusfb: drop clock fields from cirrusfb_regs structure

Move call to pixclock calculation into the cirrusfb_set_par_foo().  It
makes copy of clock registers redundant.

Simplify clock calculations further.

Subject: cirrusfb: fix 16bpp modes

The 16bpp mode did not work on the Cirrus cards as the visual type was set
to DIRECTCOLOR instead of TRUECOLOR.  The Alpine family used one incorrect
register setting so this 16bpp modes generated wrong horizontal frequency.

Subject: cirrusfb: do not change MCLK for Alpine chips

A memory clock value (MCLK) is changed to a minimum required by a current
mode bandwidth.  This usually lowers the MCLK to its minimum (50 MHz) thus
decreasing the card performance.  Just leave the MCLK value set by card
BIOS.

The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a
pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a
jitter on the screen.  A countermeasure is to use the MCLK as pixclock
source instead of a VCLK.  The patch implements this as well.

Subject: efifb/imacfb consolidation + hardware support

Remove imacfb entirely, merging its DMI table into the (otherwise very
similar) efifb driver.  This also adds hardware support for many of the
newer Intel Apple hardware.  This has been fairly well tested; we've been
shipping it in Fedora for some time.

Subject: radeonfb: misc cleanup of engine and dst cache handling

Fix a couple of incomplete tests of the chip families in the engine
init/reset code and proper initialization of the destination cache mode.
The result should better match what the latest X radeon driver does.

From b1ee26bab14886350ba12a5c10cbc0696ac679bf Mon Sep 17 00:00:00 2001

Subject: radeonfb: accelerate imageblit and other improvements

Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.

The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens.  I
removed it as it would slow down accel operations.

The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.

Overall, this improve accel performances.  The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.

Subject: uvesafb: don't treat mode info retrieval failures as errors

Some BIOSes return error codes when queried for information about
modes from their own modelist.  uvesafb treats this as an error
case and bails out.

Change this behavior so that broken modes do not prevent the driver
from working.  Only the failure to retrieve information about any
usable video mode is considered to be an error case.

There's no point in checking diff == c->vc_rows, because it can be true
only when count == 0, but we already checked that.  Additionally move
variables used only in one block to this block.

Subject: fbdev: ignore VESA modes if framebuffer does not support them

Currently, it is possible to set a graphics VESA mode at boot time via the
vga= parameter even when no framebuffer driver supporting this is
configured.  This could lead to the system booting with a black screen,
without a usable console.

Fix this problem by only allowing to set graphics modes at boot time if a
supporting framebuffer driver is configured.

The Epson s1d13xxx hardware is common in many handhelds, but our driver is

Because fbcon_set_all_vcs()->FBCON_SWAP() uses display->rotate == 0 instead
of fbcon_ops->rotate, and vc_resize() has no effect because it is called with
new_cols/rows == ->vc_cols/rows.

Tested on 2.6.26.5-45.fc9.x86_64, but
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git seems to
have the same problem.

Subject: ext2: fix ext2 block reservation early ENOSPC issue

We could run into ENOSPC error on ext2, even when there is free blocks on
the filesystem.

The problem is triggered in the case the goal block group has 0 free
blocks , and the rest block groups are skipped due to the check of
"free_blocks < windowsz/2".  Current code could fall back to non
reservation allocation to prevent early ENOSPC after examing all the block
groups with reservation on , but this code was bypassed if the reservation
window is turned off already, which is true in this case.

This patch fixed two issues:
1) We don't need to turn off block reservation if the goal block group has
0 free blocks left and continue search for the rest of block groups.

Current code the intention is to turn off the block reservation if the
goal allocation group has a few (some) free blocks left (not enough for
make the desired reservation window),to try to allocation in the goal
block group, to get better locality.  But if the goal blocks have 0 free
blocks, it should leave the block reservation on, and continues search for
the next block groups,rather than turn off block reservation completely.

2) we don't need to check the window size if the block reservation is off.

The problem was originally found and fixed in ext4.

Subject: ext2: avoid printk floods in the face of directory corruption

A very large directory with many read failures (either due to storage
problems, or due to invalid size & blocks from corruption) will generate a
printk storm as the filesystem continues to try to read all the blocks.
This flood of messages can tie up the box until it is complete - which may
be a very long time, especially for very large corrupted values.

This is fixed by only reporting the corruption once each time we try to
read the directory.

Subject: hfsplus: fix Buffer overflow with a corrupted image

When an hfsplus image gets corrupted it might happen that the catalog
namelength field gets b0rked.  If we mount such an image the memcpy() in
hfsplus_cat_build_key_uni() writes more than the 255 that fit in the name
field.  Depending on the size of the overwritten data, we either only get
memory corruption or also trigger an oops like this:

Since hfsplus_cat_build_key_uni() returns void and only has one callsite,
the check is performed at the callsite.

Subject: hfsplus: check read_mapping_page() return value

While testing more corrupted images with hfsplus, i came across
one which triggered the following bug:

This happens because the return value of read_mapping_page() is passed on
to kmap unchecked.  The bug is triggered after the first
read_mapping_page() in hfsplus_block_allocate(), this patch fixes all
three usages in this functions but leaves the ones further down in the
file unchanged.

Subject: hfs: fix namelength memory corruption

Fix a stack corruption caused by a corrupted hfs filesystem.  If the
catalog name length is corrupted the memcpy overwrites the catalog btree
structure.  Since the field is limited to HFS_NAMELEN bytes in the
structure and the file format, we throw an error if it is too long.

Subject: fs/reiserfs: use an IS_ERR test rather than a NULL test

In case of error, the function open_xa_dir returns an ERR pointer, but
never returns a NULL pointer.  So a NULL test that comes after an IS_ERR
test should be deleted.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@match_bad_null_test@
expression x, E;
statement S1,S2;
@@
x = open_xa_dir(...)
... when != x = E
(
*  if (x == NULL && ...) S1 else S2
|
*  if (x == NULL || ...) S1 else S2
)

Subject: binfmt_elf_fdpic: support auxvec base platform string

Commit 483fad1c3fa1060d7e6710e84a065ad514571739 ("ELF loader support for
auxvec base platform string") introduced AT_BASE_PLATFORM, but only
implemented it for binfmt_elf.

Given that AT_VECTOR_SIZE_BASE is unconditionally enlarged for us, and
it's only optionally added in for the platforms that set
ELF_BASE_PLATFORM, wire it up for binfmt_elf_fdpic, too.

Subject: binfmt_elf_fdpic: convert initial stack alignment to
 arch_align_stack()

binfmt_elf_fdpic seems to have grabbed a hard-coded hack from an ancient
version of binfmt_elf in order to try and fix up initial stack alignment
on multi-threaded x86, which while in addition to being unused, was also
pushed down beyond the first set of operations on the stack pointer,
negating the entire purpose.

These days, we have an architecture independent arch_align_stack(), so we
switch to using that instead. Move the initial alignment up before the
initial stores while we're at it.

The code scriblles over a local pointer whereas it appears to be trying
to write to the memory at which that pointer points.

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11397

Nobody we know can test this change.

Subject: block: sanitize invalid partition table entries

We currently follow blindly what the partition table lies about the
disk, and let the kernel create block devices which can not be accessed.
Trying to identify the device leads to kernel logs full of:
  sdb: rw=0, want=73392, limit=28800
  attempt to access beyond end of device

Here is an example of a broken partition table, where sda2 starts
behind the end of the disk, and sdb3 is larger than the entire disk:
  Disk /dev/sdb: 14 MB, 14745600 bytes
  1 heads, 29 sectors/track, 993 cylinders, total 28800 sectors
     Device Boot      Start         End      Blocks   Id  System
  /dev/sdb1              29        7800        3886   83  Linux
  /dev/sdb2           37801       45601        3900+  83  Linux
  /dev/sdb3           15602       73402       28900+  83  Linux
  /dev/sdb4           23403       28796        2697   83  Linux

The kernel creates these completely invalid devices, which can not be
accessed, or may lead to other unpredictable failures:
  grep . /sys/class/block/sdb*/{start,size}
  /sys/class/block/sdb/size:28800
  /sys/class/block/sdb1/start:29
  /sys/class/block/sdb1/size:7772

  /sys/class/block/sdb4/size:5394

With this patch, we ignore partitions which start behind the end of the disk,
and limit partitions to the end of the disk if they pretend to be larger:
  grep . /sys/class/block/sdb*/{start,size}
  /sys/class/block/sdb/size:28800
  /sys/class/block/sdb1/start:29
  /sys/class/block/sdb1/size:7772
  /sys/class/block/sdb3/start:15602
  /sys/class/block/sdb3/size:13198
  /sys/class/block/sdb4/start:23403
  /sys/class/block/sdb4/size:5394

These warnings are printed to the kernel log:
  sdb: p2 ignored, start 37801 is behind the end of the disk
  sdb: p3 size 57801 limited to end of disk

Subject: sysctl: simplify ->strategy

name and nlen parameters passed to ->strategy hook are unused, remove
them.  In general ->strategy hook should know what it's doing, and don't
do something tricky for which, say, pointer to original userspace array
may be needed (name).

Subject: pid_ns: de_thread: kill the now unneeded ->child_reaper change

de_thread() checks if the old leader was the ->child_reaper, this is not
possible any longer.  With the previous patch ->group_leader itself will
change ->child_reaper on exit.

Henceforth find_new_reaper() is the only function (apart from
initialization) which plays with ->child_reaper.

Subject: edac: make i82443bxgx_edac coexist with intel_agp

Fix 443BX/GX MCH suppport in a EDAC.

It makes i82443bxgx_edac coexist with intel_agp using the same approach as
several other EDAC drivers.

Tested on Intel's L443GX with redhat's 2.6.18 with whole EDAC subsystem
backported a while ago.

[root@host ~]# dmesg|grep -iE '(AGP|EDAC)'

This adds support for the dual-core MPC8572 processor.  We have
to support making SPR changes on each core.  Also, since we can
have multiple memory controllers sharing an interrupt, flag the
interrupts with IRQF_SHARED.

Subject: edac i5000: fix error messages

Update the i5000_edac messages, making everything pass through the EDAC
(so the log controls will work) and being more specific about the errors.
Also, it makes the miscellaneous errors optional and disabled by default.

As I didn't found anywhere information about M23ERR-M26ERR
(FERR_NF_THERMAL) on FERR_NF_FBD, I'm removing them.

Subject: edac i5000: fix thermal issues

Make the Thermal messages (temperature got past Tmid) be displayed only
once because:

1) it's the BIOS job to configure and handle the memory throttling
2) if the BIOS is broken or is aware about the condition, flooding the
   system logs won't help anything.
3) According to the specification update for Intel 5000 MCHs, all the
   revisions of this MCH have problems on the thermal sensors, making
   not automatic (a.k.a. intelligent thermal throttling) impossible.

Subject: tpm: correct tpm timeouts to jiffies conversion

This patch fixes timeouts conversion to jiffies, by replacing
msecs_to_jiffies() calls with usecs_to_jiffies().  According to TCG TPM
Specification Version 1.2 Revision 103 (pages 166, 167) TPM timeouts and
durations are returned in microseconds (usec) not in miliseconds (msec).

This fixes a long hang while loading TPM driver, if TPM chip starts in
"Idle" state instead of "Ready" state.  Without this patch - 'modprobe'
may hang for 30 seconds or more.

Subject: tpm: work around bug in Broadcom BCM0102 chipset

Patch tpm-correct-tpm-timeouts-to-jiffies-conversion reveals a bug in the
Broadcom BCM0102 TPM chipset used in the Dell Latitude D820 - although
most of the timeouts are returned in usecs as per the spec, one is
apparently returned in msecs, which results in a too-small value leading
to a timeout when the code treats it as usecs.  To prevent a regression,
we check for the known too-short value and adjust it to a value that makes
things work.

Subject: W1: fix deadlocks and remove w1_control_thread

w1_control_thread was removed which would wake up every second and process
newly registered family codes and complete some final cleanup for a
removed master.  Those routines were moved to the threads that were
previously requesting those operations.  A new function
w1_reconnect_slaves takes care of reconnecting existing slave devices when
a new family code is registered or removed.  The removal case was missing
and would cause a deadlock waiting for the family code reference count to
decrease, which will now happen.  A problem with registering a family code
was fixed.  A slave device would be unattached if it wasn't yet claimed,
then attached at the end of the list, two unclaimed slaves would cause an
infinite loop.

The struct w1_bus_master.search now takes a pointer to the struct
w1_master device to avoid searching for it, which would have caused a
lock ordering deadlock with the removal of w1_control_thread.

Subject: W1: abort search early on on exit

Early abort if the master driver or the hardware goes away in the middle
of a bus search operation.  The alternative is to spam the print buffer up
to 64*64 times with read errors in the case of USB.

Subject: W1: don't delay search start

Move the creation of the w1_process thread to after the device has been
initialized.  This way w1_process doesn't have to check to see if it has
been initialized and the bus search can proceed without sleeping.  That
also eliminates two checks in the w1_process loop.  The sleep now happens
at the end of the loop not the beginning.

Also added a comment for why the atomic_set was 2.

Subject: W1: w1_process, block or sleep

The w1_process thread's sleeping and termination has been modified.
msleep_interruptible was replaced by schedule_timeout and schedule to
allow for kthread_stop and wake_up_process to interrupt the sleep and the
unbounded sleeping when a bus search is disabled.  The W1_MASTER_NEED_EXIT
and flags variable were removed as they were redundant with
kthread_should_stop and kthread_stop.  If w1_process is sleeping,
requesting a search will immediately wake it up rather than waiting for
the end of msleep_interruptible previously.

Subject: W1: feature, enable hardware strong pullup

Add a strong pullup option to the w1 system.  This supplies extra power
for parasite powered devices.  There is a w1_master_pullup sysfs entry and
enable_pullup module parameter to enable or disable the strong pullup.

The one wire bus requires at a minimum one wire and ground.  The common
wire is used for sending and receiving data as well as supplying power to
devices that are parasite powered of which temperature sensors can be one
example.  The bus must be idle and left high while a temperature
conversion is in progress, in addition the normal pullup resister on
larger networks or even higher temperatures might not supply enough power.
 The pullup resister can't provide too much pullup current, because
devices need to pull the bus down to write a value.  This enables the
strong pullup for supported hardware, which can supply more current when
requested.  Unsupported hardware will just delay with the bus high.

The hardware USB 2490 one wire bus master has a bit on some commands which
will enable the strong pullup as soon as the command finishes executing.
To use strong pullup, call the new w1_next_pullup function to register the
duration.  The next write command will call set_pullup before sending the
data, and reset the duration to zero once it returns.

Switched from simple_strtol to strict_strtol.

+Kernel driver w1_therm
+====================
+
+Supported chips:
+  * Maxim ds18*20 based temperature sensors.
+
+Author: Evgeniy Polyakov <johnpol@2ka.mipt.ru>
+
+
+Description
+-----------
+
+w1_therm provides basic temperature conversion for ds18*20 devices.
+supported family codes:
+W1_THERM_DS18S20	0x10
+W1_THERM_DS1822		0x22
+W1_THERM_DS18B20	0x28
+
+Support is provided through the sysfs w1_slave file.  Each open and
+read sequence will initiate a temperature conversion then provide two
+lines of ASCII output.  The first line contains the nine hex bytes
+read along with a calculated crc value and YES or NO if it matched.
+If the crc matched the returned values are retained.  The second line
+displays the retained values along with a temperature in millidegrees
+Centigrade after t=.
+
+Parasite powered devices are limited to one slave performing a
+temperature conversion at a time.  If none of the devices are parasite
+powered it would be possible to convert all the devices at the same
+time and then go back to read individual sensors.  That isn't
+currently supported.  The driver also doesn't support reduced
+precision (which would also reduce the conversion time).
+
+The module parameter strong_pullup can be set to 0 to disable the
+strong pullup or 1 to enable.  If enabled the 5V strong pullup will be
+enabled when the conversion is taking place provided the master driver
+must support the strong pullup (or it falls back to a pullup
+resistor).  The DS18b20 temperature sensor specification lists a
+maximum current draw of 1.5mA and that a 5k pullup resistor is not
+sufficient.  The strong pullup is designed to provide the additional
+current required.

Subject: W1: recode w1_slave_found logic

Simplified the logic in w1_slave_found by using the new
w1_attach_slave_device function to find a slave and mark it as active or
add the device if the crc checks.

Subject: W1: w1_slave_read_id read bug, use device_attribute

Fix bug reading the id sysfs file.  If less than the full 8 bytes were
read, the next read would start at the first byte instead of continuing.
It needed the offset added to memcpy, or the better solution was to
replace it with the device attribute instead of bin attribute.

Subject: W1: w1_therm fix user buffer overflow and cat

Fixed data reading bug by replacing binary attribute with device one.

Switching the sysfs read from bin_attribute to device_attribute.  The data
is far under PAGE_SIZE so the binary interface isn't required.  As the
device_attribute interface will make one call to w1_therm_read per file
open and buffer, the result is, the following problems go away.

buffer overflow:
	Execute a short read on w1_slave and w1_therm_read_bin would still
	return the full string size worth of data clobbering the user space
	buffer when it returned.  Switching to device_attribute avoids the
	buffer overflow problems.  With the snprintf formatted output dealing
	with short reads without doing a conversion per read would have
	been difficult.
bad behavior:
	`cat w1_slave` would cause two temperature conversions to take place.
	Previously the code assumed W1_SLAVE_DATA_SIZE would be returned with
	each read.  It would not return 0 unless the offset was less
	than W1_SLAVE_DATA_SIZE.  The result was the first read did a
	temperature conversion, filled the buffer and returned, the
	offset in the second read would be less than
	W1_SLAVE_DATA_SIZE and also fill the buffer and return, the
	third read would finnally have a big enough offset to return 0
	and cause cat to stop.  Now w1_therm_read will be called at
	most once per open.

Subject: W1: w1_io.c reset comments and msleep

w1_reset_bus, added some comments about the timing and switched to msleep
for the later delay.  I don't have the hardware to test the sleep after
reset change.  The one wire doesn't have a timing requirement between
commands so it is fine.  I do have the USB hardware and it would be in big
trouble with 10ms interrupt transfers to find that the reset completed.

Subject: W1: ds1wm.c msleep for reset

Like the previous w1_io.c reset coments and msleep patch, I don't have the
hardware to verify the change, but I think it is safe.  It also helps to
see a comment like this in the code.  "We'll wait a bit longer just to be
sure." If they are going to calculate delaying 324.9us, but actually delay
500us, why not just give up the CPU and sleep?  This is designed for a
battery powered ARM system, avoiding busywaiting has to be good for
battery life.

I sent a request for testers March 7, 2008 to the Linux kernel mailing
list and two developers who have patches for ds1wm.c, but I didn't get
any respons.

Subject: W1: ds2490.c add support for strong pullup

Add strong pullup support for ds2490 driver, also drop mdelay(750), which
busy waits, usage in favour of msleep for long delays.  Now with msleep
only being called when the strong pullup is active, one wire bus
operations are only taking minimal system overhead.

The new set_pullup will only enable the strong pullup when requested,
which is expected to be the only write operation that will benefit from a
strong pullup.

Subject: W1: ds2490.c ds_write_bit, grouping error, disable readback

ds_write_bit doesn't read the input buffer, so add COMM_ICP and a comment
that it will no longer generate a read back data byte.  If there is an
extra data byte later on then it will cause an error and discard what data
was there.  Corrected operator ordering for ds_send_control.

Don't export read and write bit operations, they didn't work, they weren't
used, and they can't be made to work.  The one wire low level bit
operations expect to set high or low levels, the ds2490 hardware only
supports complete read or write time slots, better to just comment them
out.

Subject: W1: ds2490.c simplify and fix ds_touch_bit

Simplify and fix ds_touch_bit.  If a device is attached in the middle of a
bus search the status register will return more than the default 16 bytes.
 The additional bytes indicate that it has detected a new device.  The way
ds_wait_status is coded, if it doesn't read 16 status bytes it returns an
error value.  ds_touch_bit then will detect that error and return an
error.  In that case it doesn't read the input buffer and returns
uninitialized data.  It doesn't stop there.  The next transaction will not
expect the extra byte in the input buffer and the short read will cause an
error and clear out both the old byte and new data in the input buffer.

Just ignore the value of ds_wait_status.  It is still required to wait
until ds2490 is again idle and there is data to read when ds_recv_data is
called.  This also removes the while loop.  None of the other commands
wait and verify that the issued command is in the status register.

Subject: W1: ds2490.c ds_dump_status rework

- add result register #defines
- rename ds_dump_status to ds_print_msg
- rename ds_recv_status to ds_dump_status
- ds_dump_status prints the requested status and no longer reads the
  status, this is because the second status read can return different
  data for example the result register
- the result register will be printed, though limited to detecting a
  new device, detecting other values such as a short would require
  additional reporting methods
- ST_EPOF was moved to ds_wait_status to clear the error condition
  sooner

Reset the device in init as it can be in a bad state.  This is necessary
because a block write will wait for data to be placed in the output buffer
and block any later commands which will keep accumulating and the device
will not be idle.  Another case is removing the ds2490 module while a bus
search is in progress, somehow a few commands get through, but the input
transfers fail leaving data in the input buffer.  This will cause the next
read to fail see the note in ds_recv_data.

 DS9490(R) is a USB <-> W1 bus master device
 which has 0x81 family ID integrated chip and DS2490
 low-level operational chip.
+
+Notes and limitations.
+- The weak pullup current is a minimum of 0.9mA and maximum of 6.0mA.
+- The 5V strong pullup is supported with a minimum of 5.9mA and a
+  maximum of 30.4 mA.  (From DS2490.pdf)
+- While the ds2490 supports a hardware search the code doesn't take
+  advantage of it (in tested case it only returned first device).
+- The hardware will detect when devices are attached to the bus on the
+  next bus (reset?) operation, however only a message is printed as
+  the core w1 code doesn't make use of the information.  Connecting
+  one device tends to give multiple new device notifications.
+- The number of USB bus transactions could be reduced if w1_reset_send
+  was added to the API.  The name is just a suggestion.  It would take
+  a write buffer and a read buffer (along with sizes) as arguments.
+  The ds2490 block I/O command supports reset, write buffer, read
+  buffer, and strong pullup all in one command, instead of the current
+  1 reset bus, 2 write the match rom command and slave rom id, 3 block
+  write and read data.  The write buffer needs to have the match rom
+  command and slave rom id prepended to the front of the requested
+  write buffer, both of which are known to the driver.
+- The hardware supports normal, flexible, and overdrive bus
+  communication speeds, but only the normal is supported.
+- The registered w1_bus_master functions don't define error
+  conditions.  If a bus search is in progress and the ds2490 is
+  removed it can produce a good amount of error output before the bus
+  search finishes.
+- The hardware supports detecting some error conditions, such as
+  short, alarming presence on reset, and no presence on reset, but the
+  driver doesn't query those values.
+- The ds2490 specification doesn't cover short bulk in reads in
+  detail, but my observation is if fewer bytes are requested than are
+  available, the bulk read will return an error and the hardware will
+  clear the entire bulk in buffer.  It would be possible to read the
+  maximum buffer size to not run into this error condition, only extra
+  bytes in the buffer is a logic error in the driver.  The code should
+  should match reads and writes as well as data sizes.  Reads and
+  writes are serialized and the status verifies that the chip is idle
+  (and data is available) before the read is executed, so it should
+  not happen.
+- Running x86_64 2.6.24 UHCI under qemu 0.9.0 under x86_64 2.6.22-rc6
+  with a OHCI controller, ds2490 running in the guest would operate
+  normally the first time the module was loaded after qemu attached
+  the ds2490 hardware, but if the module was unloaded, then reloaded
+  most of the time one of the bulk out or in, and usually the bulk in
+  would fail.  qemu sets a 50ms timeout and the bulk in would timeout
+  even when the status shows data available.  A bulk out write would
+  show a successful completion, but the ds2490 status register would
+  show 0 bytes written.  Detaching qemu from the ds2490 hardware and
+  reattaching would clear the problem.  usbmon output in the guest and
+  host did not explain the problem.  My guess is a bug in either qemu
+  or the host OS and more likely the host OS.

Subject: W1: ds2490.c optimize ds_set_pullup

Optimize the ds_set_pullup function.  For a strong pullup to be sent the
ds2490 has to have both the strong pullup mode enabled, and the specific
write operation has to have the SPU bit enabled.  Previously the write
always had the SPU bit enabled and both the duration and model was set
when a strong pullup was requested.  Now the strong pullup mode is enabled
at initialization time, the delay is updated only when the value changes,
and the write SPU bit is set only when a strong pullup is required.  This
removes two or three bus transactions per strong pullup request.

Subject: Configure out AIO support

This patchs adds the CONFIG_AIO option which allows to remove support
for asynchronous I/O operations, that are not necessarly used by
applications, particularly on embedded devices. As this is a
size-reduction option, it depends on CONFIG_EMBEDDED. It allows to
save ~7 kilobytes of kernel code/data:

   text	   data	    bss	    dec	    hex	filename
1115067	 119180	 217088	1451335	 162547	vmlinux
1108025	 119048	 217088	1444161	 160941	vmlinux.new
  -7042    -132       0   -7174   -1C06 +/-

This patch has been originally written by Matt Mackall
<mpm@selenic.com>, and is part of the Linux Tiny project.

Subject: GRU driver: minor updates

A few minor updates for the GRU driver.
	- documentation changes found in code reviews
	- changes to #ifdefs to make them recognized by "unifdef"
	  (used in simulator testing)
	- change GRU context load/unload to prefetch data

the third character is a valid hex digit.

Subject: lib: remove defining macros for strict_strto??

Open-code them rather than using defining macros.  The function bodies are now
next to their kerneldoc comments as a bonus.

Add casts to the signed cases as they call into the unsigned versions.

Avoids the sparse warnings:
lib/vsprintf.c:249:1: warning: incorrect type in argument 3 (different signedness)
lib/vsprintf.c:249:1:    expected unsigned long *res
lib/vsprintf.c:249:1:    got long *res

Subject: frv: use generic pci_enable_resources()

Use the generic pci_enable_resources() instead of the arch-specific code.

Unlike this arch-specific code, the generic version:
    - checks PCI_NUM_RESOURCES (11), not 6, resources
    - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
    - skips ROM resources unless IORESOURCE_ROM_ENABLE is set
    - checks for resource collisions with "!r->parent"

As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory.  Thus a NULL test or memset after calls to these
functions is unnecessary.

Subject: Fix kernel/softirq.c printk format warning properly

This fixes the broken 77af7e3403e7314c47b0c07fbc5e4ef21d939532
("softirq, warning fix: correct a format to avoid a warning") fix
correctly.

The type of a pointer subtraction is not "int", nor is it "long".  It
can be either (or something else).  It's "ptrdiff_t", and the printk
format for it is "%td".

Subject: {pci,pnp} quirks.c: don't use deprecated print_fn_descriptor_symbol()

I dunno how this missed Bjorn and his quest to use %pF in commit
c80cfb0406c01bb5da91bfe30f5cb1fd96831138 ("vsprintf: use new vsprintf
symbolic function pointer format"), but it did.

So use %pF in the two remaining places that still tried to print out
function pointers by hand.

Subject: ext4: Replace hackish ext4_mb_poll_new_transaction with commit
 callback

The multiblock allocator needs to be able to release blocks (and issue
a blkdev discard request) when the transaction which freed those
blocks is committed.  Previously this was done via a polling mechanism
when blocks are allocated or freed.  A much better way of doing things
is to create a jbd2 callback function and attaching the list of blocks
to be freed directly to the transaction structure.

Subject: ext4: Remove automatic enabling of the HUGE_FILE feature flag

If the HUGE_FILE feature flag is not set, don't allow the creation of
large files, instead of automatically enabling the feature flag.
Recent versions of mke2fs will set the HUGE_FILE flag automatically
anyway for ext4 filesystems.

Subject: block: add partition attribute for partition number

With extended devt, finding out the partition number becomes a bit
more challenging as subtracting the minor number from that of the
parent device doesn't work anymore.  The only thing left is parsing
the partition name which is brittle and not exactly universal (some
have '-' between the device name and partition number while others
don't).  This patch introduced partition attribute which contains the
partition number of the device.  This should make finding partitions
and its index easier.

This problem and solution were suggested by H. Peter Anvin.

Subject: block: fix nr_phys_segments miscalculation bug

This fixes the bug reported by Nikanth Karthikesan <knikanth@suse.de>:

http://lkml.org/lkml/2008/10/2/203

The root cause of the bug is that blk_phys_contig_segment
miscalculates q->max_segment_size.

blk_phys_contig_segment checks:

req->biotail->bi_size + next_req->bio->bi_size > q->max_segment_size

But blk_recalc_rq_segments might expect that req->biotail and the
previous bio in the req are supposed be merged into one
segment. blk_recalc_rq_segments might also expect that next_req->bio
and the next bio in the next_req are supposed be merged into one
segment. In such case, we merge two requests that can't be merged
here. Later, blk_rq_map_sg gives more segments than it should.

We need to keep track of segment size in blk_recalc_rq_segments and
use it to see if two requests can be merged. This patch implements it
in the similar way that we used to do for hw merging (virtual
merging).

Subject: block: only call ->request_fn when the queue is not stopped

Callers should use either blk_run_queue/__blk_run_queue, or
blk_start_queueing() to invoke request handling instead of calling
->request_fn() directly as that does not take the queue stopped
flag into account.

Also add appropriate comments on the above functions to detail
their usage.

Subject: block: move q->unplug_work initialization

modprobe loop; rmmod loop effectively creates a blk_queue and destroys it
which results in q->unplug_work being canceled without it ever being
initialized.

Therefore, move the initialization of q->unplug_work from
blk_queue_make_request() to blk_alloc_queue*().

Subject: block: remove __generic_unplug_device() from exports

The only out-of-core user is IDE, and that should be using
blk_start_queueing() instead.

Move the code which aggregates two 8-bit register values into a 16-bit
value to a separate function. We'll need to do it a second time soon and
I don't want to duplicate the code.

Subject: hwmon: (lm90) Don't access nonexistent registers on Maxim chips

The Maxim chips supported by the lm90 driver have 8-bit high and low
remote limit values, not 11-bit as the other chips have. So stop reading
from and writing to registers that do not exist on these chips. Also
round the limit values set by the user properly.

Subject: hwmon: (lm90) Update datasheet links

Update the links to the datasheet of some of the devices supported by
the lm90 driver. Also remove the links from the driver itself, so that
we don't have to update them twice each time they change.

Subject: hwmon: (lm90) Convert some macros to static functions

Use static functions instead of the TEMPx_FROM_REG* and TEMPx_TO_REG*
macros.  This will ensure type safety and eliminate any side effects
from arguments passed in since the macros referenced 'val' multiple
times.  This change should not affect functionality.

Subject: hwmon: (lm90) Rename temperature conversion functions to match usage

The encoding of temperatures varies between chips and modes.  So do not
use "temp1" or "temp2" in the names of the conversion functions, but
specify the encoding.

Subject: hwmon: (lm90) Don't spam the kernel log

Degrade the "Unsupported chip" message from info to debug level.
There's nothing wrong with this, so no need to bother the user.
Also make the message slightly more descriptive.

Subject: hwmon: (lm87) Fix masking of config register in lm87_init_client()

lm87_init_client() conditionally sets the Start bit and clears the
INT#_Clear bit in the Config 1 register.  The condition should be that
either of these bits needs changing, but currently it checks the
(self-clearing) Initialization bit instead of INT#_Clear.

Fix the condition and also ensure we never set the Initialization bit.

Subject: hwmon: (ams) Convert to a new-style i2c driver

The legacy i2c binding model is phasing out, so the ams driver needs
to be converted to a new-style i2c driver. Here is a naive approach of
this conversion. Basically it is moving the i2c device creation from
the ams driver to the i2c-powermac driver. This should work, but I
suspect we could come up with something cleaner by declaring the i2c
device as part of the platform setup. This could be done later by
someone more familiar with openfirmware-based platforms than I am
myself.

One nice thing brought by this conversion is that the ams driver
should be loaded automatically on systems where is is needed (at
least when the I2C interface to the chip is used) providing
coldplug-aware user-space environment.

Subject: hwmon: (ams) Fix permissions on 'joystick' module parameter

We should not allow writes to the 'joystick' module parameters since
writing there will not trigger creation of the input device. Disable
writes since we provide alternative way of enabling input device via
AMS device's sysfs attribute.

Subject: hwmon: (ams) Fix locking issues

Use a separate mutex to serialize input device creation/removal,
otheriwse we deadlock if we try to remove input device while it is
being polled. Also do not take ams_info.lock when it is not needed.

Subject: hwmon: (lm85) Implement the standard PWM frequency interface

Implement the standard PWM frequency interface: pwm[1-*]_freq in
units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq
in units of 0.1 Hz. The old naming was not only non-standard, it was
also confusing, because it suggested that the frequency value only
applied in automatic fan speed mode, which isn't true.

Subject: hwmon: (lm85) Select the closest PWM frequency

The LM85 and compatible chips only support 8 arbitrary PWM frequencies.
The algorithm to pick one of them based on the user input is not
optimum. Improve it to always pick the closest supported frequency.

Function RANGE_TO_REG can easily be simplified. Credits go to Herbert

Subject: hwmon: (lm78) Fix I/O resource conflict with PNP

Only request I/O ports 0x295-0x296 instead of the full I/O address
range. This solves a conflict with PNP resources on a few motherboards.

Also request the I/O ports in two parts (4 low ports, 4 high ports)
during device detection, otherwise the PNP resource make the request
(and thus the detection) fail.

This is the exact same fix that was applied to driver w83781d in
March 2008 to address the same problem:

Subject: hwmon: (lm78) Detect alias chips

The LM78 and LM79 can be accessed either on the I2C bus or the ISA
bus. We must not access the same chip through both interfaces. So far
we were relying on the user passing the correct ignore parameter to
skip the registration of the I2C interface as suggested by
sensors-detect, but this is fragile: the user may load the lm78
driver without running sensors-detect, and the i2c bus numbers are
not stable across reboots and hardware changes.

So, better detect alias chips in the driver directly, and skip any
I2C chip which is obviously an alias of the ISA chip. This is done
by comparing the value of 26 selected registers.

The LM78 detection is relatively weak, and sometimes recent Winbond
chips can be misdetected as an LM78. We have had repeated reports of
this happening. We have an explicit check against this for the ISA
access, do the same for I2C access now.

Subject: hwmon: (it87) Fix thermal sensor type values

The it87 driver doesn't follow the standard sensor type values as
documented in Documentation/hwmon/sysfs-interface. It uses value 2 for
thermistors instead of value 4. This causes "sensors" to tell the user
that the chip is setup for a transistor while it is actually setup for
a thermistor.

Using value 4 for thermistors solves the problem. For compatibility
reasons, we still accept value 2 but emit a warning message so that
users update their configuration files.

Subject: hwmon: (w83791d) fan 4/5 pins can also be used for gpio

Pins fan/pwm 4-5 can be in use as GPIO. If that is the case, do not
create their sysfs-interface.

+The driver implements three temperature sensors, ten voltage sensors,
+five fan rotation speed sensors and manual PWM control of each fan.
 
 Temperatures are measured in degrees Celsius and measurement resolution is 1
 degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
 the temperature gets higher than the Overtemperature Shutdown value; it stays
 on until the temperature falls below the Hysteresis value.

+An alarm is triggered if the voltage has crossed a programmable minimum

+
 Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
 triggered if the rotation speed has dropped below a programmable limit. Fan
 readings can be divided by a programmable divider (1, 2, 4, 8, 16,
 32, 64 or 128 for all fans) to give the readings more range or accuracy.

+Each fan controlled is controlled by PWM. The PWM duty cycle can be read and

 The w83791d has a global bit used to enable beeping from the speaker when an

 specific alarms. You need both the global beep enable bit and the
 corresponding beep bit to be on for a triggered alarm to sound a beep.

Subject: hwmon: (w83781d) Detect alias chips

The W83781D and W83782D can be accessed either on the I2C bus or the
ISA bus. We must not access the same chip through both interfaces. So
far we were relying on the user passing the correct ignore parameter
to skip the registration of the I2C interface as suggested by
sensors-detect, but this is fragile: the user may load the w83781d
driver without running sensors-detect, and the i2c bus numbers are
not stable across reboots and hardware changes.

So, better detect alias chips in the driver directly, and skip any
I2C chip which is obviously an alias of the ISA chip. This is done
by comparing the value of 26 selected registers.

Subject: hwmon: (w83781d) Additional information about AS99127F PWM

This information was provided in lm-sensors ticket #2350:
http://www.lm-sensors.org/ticket/2350

This is IMHO still not enough to be able to safely implement fan
control support for the AS99127F, but this is valuable information so
I am adding it to the documentation.

Subject: hwmon: (w83781d) Make ISA interface depend on CONFIG_ISA

Probing the ISA bus on systems without ISA bus may hang the system.
This patch makes the ISA bus related code depend on the kernel
configuration parameter CONFIG_ISA. It moves ISA bus related code
into one #ifdef CONFIG_ISA ... #endif block and adds some helper
function.

Subject: hwmon: (w83781d) Stop abusing struct i2c_client for ISA devices

Upcoming changes to the I2C part of the w83781d driver will cause ISA
devices to no longer have a struct i2c_client at hand. So, we must
stop (ab)using it now.

Subject: hwmon: (w83781d) Use new style driver binding

This patch modifies the w83781d driver to use new style driver binding.
Substantial code modifications are required to deal with the new
interface, especially legacy device detection.

[JD: largely edited to make the patch smaller and to get the driver
to work again on ISA devices.]

+Kernel driver adt7470
+=====================
+
+Supported chips:
+  * Analog Devices ADT7470
+    Prefix: 'adt7470'
+    Addresses scanned: I2C 0x2C, 0x2E, 0x2F
+    Datasheet: Publicly available at the Analog Devices website
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7470 chip.  There may
+be other chips that implement this interface.
+
+The ADT7470 uses the 2-wire interface compatible with the SMBus 2.0
+specification. Using an analog to digital converter it measures up to ten (10)
+external temperatures. It has four (4) 16-bit counters for measuring fan speed.
+There are four (4) PWM outputs that can be used to control fan speed.
+
+A sophisticated control system for the PWM outputs is designed into the ADT7470
+that allows fan speed to be adjusted automatically based on any of the ten
+temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the ADT7470 will adjust the PWM outputs in
+response to the measured temperatures with further host intervention.  This
+feature can also be disabled for manual control of the PWM's.
+
+Each of the measured inputs (temperature, fan speed) has corresponding high/low
+limit values. The ADT7470 will signal an ALARM if any measured value exceeds
+either limit.
+
+The ADT7470 DOES NOT sample all inputs continuously.  A single pin on the
+ADT7470 is connected to a multitude of thermal diodes, but the chip must be
+instructed explicitly to read the multitude of diodes.  If you want to use
+automatic fan control mode, you must manually read any of the temperature
+sensors or the fan control algorithm will not run.  The chip WILL NOT DO THIS
+AUTOMATICALLY; this must be done from userspace.  This may be a bug in the chip
+design, given that many other AD chips take care of this.  The driver will not
+read the registers more often than once every 5 seconds.  Further,
+configuration data is only read once per minute.
+
+Special Features
+----------------
+
+The ADT7470 has a 8-bit ADC and is capable of measuring temperatures with 1
+degC resolution.
+
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+
+Configuration Notes
+-------------------
+
+Besides standard interfaces driver adds the following:
+
+* PWM Control
+
+* pwm#_auto_point1_pwm and pwm#_auto_point1_temp and
+* pwm#_auto_point2_pwm and pwm#_auto_point2_temp -
+
+point1: Set the pwm speed at a lower temperature bound.
+point2: Set the pwm speed at a higher temperature bound.
+
+The ADT7470 will scale the pwm between the lower and higher pwm speed when
+the temperature is between the two temperature boundaries.  PWM values range
+from 0 (off) to 255 (full speed).  Fan speed will be set to maximum when the
+temperature sensor associated with the PWM control exceeds
+pwm#_auto_point2_temp.
+
+Notes
+-----
+
+As stated above, the temperature inputs must be read periodically from
+userspace in order for the automatic pwm algorithm to run.

Subject: V4L/DVB (9191): ivtv: partially revert an earlier patch that checks
 the max image height

Ian Armstrong pointed out to me that it is perfectly valid to have a
576 lines YUV video with NTSC output in this particular case. In fact,
without this the X driver for ivtv does not function properly.

Reverted my earlier change that restrictred the height to 480 for NTSC
and add the comments provided by Ian to explain what is happening here.

Subject: V4L/DVB (9193): stk-webcam: minor cleanup

This patch:
1) removes the unnecessary kref.h include file
2) removes unnecessary pointer validation from read and poll routines.
(Neither poll nor read may be called unless a call to open succeeds. A
successful call to open will always set the file private_data pointer.
Verifying that it is not null is therefore unnecessary. The associated
release and mmap calls currently ignore this check.)
3) adds a space to syslog output.
4) removes an unused function prototype.

Subject: V4L/DVB (9194): stk-webcam: fix crash on close after disconnect

This patch prevents stk-webcam from updating usb device information
once the camera has been removed. This prevents a crash that would
otherwise occur if the camera is disconnected while it is still in
use.

From a8c26dfe00e147012bd6a1b3bd206b4771bb5bd7 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 07:59:35 -0300
Subject: V4L/DVB (9201): bt856: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

From c18fdcf65732b87f6015ea4e423fc7abf7c26dd2 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 07:59:54 -0300
Subject: V4L/DVB (9202): bt866: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

Date: Sun, 7 Sep 2008 08:00:14 -0300
Subject: V4L/DVB (9203): ks0127: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 08:00:32 -0300
Subject: V4L/DVB (9204): saa7110: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

Date: Sun, 7 Sep 2008 08:00:49 -0300
Subject: V4L/DVB (9205): saa7111: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 08:01:05 -0300
Subject: V4L/DVB (9206): saa7114: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 08:01:20 -0300
Subject: V4L/DVB (9207): saa7185: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

From 23848b655ab5fc2fe88ef99e90ad8e4c41304d76 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Sun, 7 Sep 2008 08:01:39 -0300
Subject: V4L/DVB (9208): vpx3220: convert i2c driver for new i2c API

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

Subject: V4L/DVB (9209): v4l2: add comment to the v4l2-i2c-drv headers.

Looking at these headers as they appear in the kernel makes you
wonder why it is done that way. Refer to the v4l-dvb repository
where the full unstripped header can be found to understand the
reasoning behind this.

Subject: V4L/DVB (9214): si470x: improvement of module device support

This patch improves support for multiple radio devices.

In previous versions all region relevant settings were derived from one
module parameter. As in future versions, the region and other
configuration should be configurable per device from the user space,
this patch already retrieves all relevant information from the actual
device specific settings.

Subject: V4L/DVB (9215): si470x: improvement of unsupported base controls

This patch changes the handling of unsupported base controls.

In the former version, specific unsupported base controls were listed in
the queryctrl table and were flagged as disabled controls. This was done
for all base controls used by the applications.

The patch now removes the specific base controls and instead lets
queryctrl automatically return unsupported base controls flagged as
disabled.

Subject: V4L/DVB (9216): si470x: tuner->type handling

The V4L2 specification says, when to check and when to return
tuner->type as constant value.

This patch corrects exactly this behavior, so that it is now conform to
the V4L2 specification.

Subject: V4L/DVB (9218): si470x: removement of get/set input/audio

This patch removes the unnecessary get/set input/audio functions.

The reason is, that the V4L2 specification says, that if input or audio
cannot be switched anyway, the functions doesn't need to be implemented.

I've tested the new driver with all current radio programs in
Debian/testing and found no problems with that.

In my opinion, the driver is much cleaner by removing these unnecessary
functions.

Subject: V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter
 support.

A detailed description from the original patches 2 years ago:

"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.

So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)

Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)

The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.

*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."

It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:

Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner

Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.

TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.

HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.

From 92abe9ee374599179033f039b095864a9cf74593 Mon Sep 17 00:00:00 2001
From: Darron Broad <darron@kewl.org>
Date: Sat, 11 Oct 2008 11:18:53 -0300
Subject: V4L/DVB (9223): MFE: Fix a number of bugs and some tidying up

A number of reference to videobuf_dvb_get_frontend used an invalid
index. This has been fixed.

The section for the HVR3000 in advise_acquire was redundant as
the same logic is used on the HVR4000. This has been removed
and both cards now use the same function.

A number of small errors and whitespace errors are also fixed.

Subject: V4L/DVB (9224): MFE: bugfix: add missing frontend allocation

When using MFE on a setup with both and HVR-3000 and ASUS P7131
card it was noticed that frontend allocation for saa7134
adapters was missing. This patch adds that allocation for
both saa7134 and cx23885 adapters.

Subject: V4L/DVB (9225): MFE: Add configurable gate control

This adds a configurable (one per card) gate control option
for multi-frontend. Prior to this point gate control was
assumed to be on the primary frontend, this is a fault
when the gate to the analogue section is on the secondary
which is the default for both the HVR-3000 and HVR-4000
in MFE.

Subject: V4L/DVB (9227): MFE: Add multi-frontend mutual exclusion

This add frontend R/W mutual exclusion.
Prior to this point in time it was possible to open both
frontends simultaneously which an MFE card cannot support.

In order to stop this, a delayed open is performed which
has the following function:

-  Return EBUSY after a configurable amount of time
   if a frontend is unavailable due to the other being
   in use.

-  Only allow opening of a frontend if the kernel thread
   of the other has stopped.

This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel
thread.

Subject: V4L/DVB (9228): cx88: Add audio routing for the hvr-3000/4000

This adds audio routing on the hvr-3000/4000

This is a preliminary patch for later routing
requirements.

This adds line-in support on the 2 cards mentioned.
It is also apparent that there is an initial open
fault for line-in when opening composite/s-video.
This will be fixed later.

It was also noticed that the bit-field for audio
routing which was 2 bits needs an increase as
the WM8775 for example, allows a value 4 bits
wide for it's audio mux.

Subject: V4L/DVB (9229): cx88: Add intial config for FM radio support

This add initial configuration for radio support on the
hvr-3000/4000. FM radio doesn't work as yet without
further patches (to come), but this prepares for
that.

Experimental radio support shows that it works
when combined with additional audio routing
work for cards with an FMD1216ME analogue
frontend, but not the MEX variant (more later).

now when the MFE patches is fresh in peoples mind, rather than 12 months
from now when new cards appear.

Subject: V4L/DVB (9232): cx23885: Move the MFE frontend allocation into the
 correct place

cx23885 frontend allocation code needs to exist in the higher function,
and it also needs to ensure videobug is also correctly initialised
on a per frontend basis. This code uses the previous num_frontends
patch to safely init each future MFE frontend on a single tsport as
as safely as possible - given that we don't have any of those boards.
Again, better to add all of this safety code now, while the MFE patch
set is fresh in everyone mind, than to try and add it 12-24 months from
now, when the subject is cold.

Subject: V4L/DVB (9235): Precalculate vivi yuv values

This patch improves the color space conversion code in vivi.c to
directly draw with precalculated YUV values as palette instead of
drawing with YUV that is calculated from RGB for every two pixels.
This way we eliminate the need for 9 multiplications every two pixels.

A side effect of this patch is that the time counter is changed from
green text on black background to white text on black background.

Subject: V4L/DVB (9238): Add support for rgb565 pixel formats to vivi

This patch adds RGB565 pixel format support to the vivi driver. Both
little endian and big endian versions are added. The driver follows
the RGB pixel format described in Table 2-2 of the V4L2 API spec,
_not_ the older BGR interpretation described in Table 2-1.

Subject: V4L/DVB (9241): soc-camera: move sensor power management to
 soc_camera_platform.c

Switching sensors on and off is now done by sensor drivers themselves,
typically using platform-provided hooks. Update soc_camera_platform.c to
do the same. Also remove a refundant struct soc_camera_platform_info
definition from soc_camera_platform.c.

Subject: V4L/DVB (9244): video: improve sh_mobile_ceu buffer handling

This patch improves the buffer handling in the sh_mobile_ceu driver.

Instead of marking all queued buffers as VIDEOBUF_ACTIVE the code now
marks queued-but-not-active buffers as VIDEOBUF_QUEUED and buffers
involved in dma as VIDEOBUF_ACTIVE. The code is also updated with
code to cancel active buffers, thanks to Morimoto-san.

Subject: V4L/DVB (9262): cx88: Change spurious buffer message into a debug
 only message

A number of users have complained that their syslog often shows this
messages but it doesn't impact performance. I'm changing this to a debug
message, so developers will still see the message during testing and
users will no longer be bothered by this.

Subject: V4L/DVB (9264): MFE: bugfix: multi-frontend mutual exclusion parallel
 open

When moving from one frontend to another
an application could spawn multiple threads opening
the same new frontend and in some circumstances all of
these could become delayed waiting for the previous
frontend readers or previous frontend writer thread to
complete.

In this scenario the first thread will succeed on open
to bring the new frontend online but any others will return
EBUSY. This is a fault.  If the first succeeds and all others
are on the same frontend then they should succeed also.

Subject: V4L/DVB (9267): cx88: Update of audio routing config for FM radio

This adds audio routing for the hvr-1300/3000/4000 cards
enabling FM audio for the I2S ADC method of the cx88.

At this time only the HVR-4000 has been tested. It
is assumed the HVR-3000/1300 are the same.

This tuner was already supported by proxy as an FMD1216ME, however,
the MEX uses a different FM Radio IF so this addition is now required.

Subject: V4L/DVB (9269): cx88: add I2S-ADC tvaudio method

This adds I2S-ADC tvaudio mode as a formal method of audio
delivery.

This fixes one bug and adds fm audio via I2S-ADC on cards
that support it.

The bug occured before when I2S-ADC mode was initiated on
composite/s-video open but was then reset within 500ms
by the audio thread which used any previous audio tuning
details.

Subject: V4L/DVB (9270): cx24116: optimise emulated auto-pilot

Christophe divulged the following:
"Since 8PSK (and higher mod) signals are very likely to have pilot symbols,
pilot_auto should start with pilot_on for 8PSK.
And since QPSK signals are unlikely to have pilot, pilot_auto should start
with pilot_off for QPSK.

Without the patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~900ms
with patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~100ms
"

This patch does as Cristophe asks. In emulated auto-pilot we
choose pilot-on for tuning PSK_8 and pilot-off for
tuning QPSK.

Subject: V4L/DVB (9271): videobuf: data storage optimisation (2)

To optimise data storage even further one other redundant
var has been removed.

This also removes a redundant assignment.

Subject: V4L/DVB (9272): mxl5005s: Bug fix stopped DVB-T from working the
 second time around.

Jose reported:

I am using a Avermedia Volar X with af9015 driver(DVB-T).

The first time you use the card, first call reconfigure with MXL_QAM,
and when tune DVB-T it calls reconfigure with MXL_DVBT. But if you close
the frontend and open again, it calls reconfigure with MXL_QAM, but not
call reconfigure with MXL_DVBT because state->current_mode don't change
(is MXL_DVBT).

Subject: V4L/DVB (9275): dvb: input data pointer of cx24116_writeregN() should
 be const

| drivers/media/dvb/frontends/cx24116.c:573: warning: passing argument 3 of 'cx24116_writeregN' discards qualifiers from pointer target type

Make the `data' input pointer parameter of cx24116_writeregN() const to
kill the warning.

Subject: V4L/DVB (9276): videobuf-dvb: two functions are now static

This patch marks those two functions as static:
	static int videobuf_dvb_register_adapter(struct videobuf_dvb_frontends *fe,
	static int videobuf_dvb_register_frontend(struct dvb_adapter *adapter,

Since MFE patches changed their calls by videobuf_dvb_register_bus.

To avoid having to declare the prototypes, the patch moves
videobuf_dvb_register_bus() to be after the declaration of the above functions
used there.

Subject: SiS DRM: fix the memory allocator if the SIS FB is built as a module

Fix the SIS DRM memory allocator if the SIS FB built as a module.  The SIS DRM
code initialises the mm allocation hooks, but _only_ if the SIS FB is not
built as a module because it depends on CONFIG_FB_SIS, and that's unset if the
SIS FB is not built in.  It must check CONFIG_FB_SIS_MODULE as well.

The driver can know what hardware requires MI_BATCH_BUFFER vs
MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.

Subject: i915: Add support for MSI and interrupt mitigation.

Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's
failure to update the sarea seqno value when the status page indicated that
the seqno had already been passed.  MSI support has been seen to cut CPU
costs by up to 40% in some workloads by avoiding other expensive interrupt
handlers for frequent graphics interrupts.

Subject: separate i915 suspend/resume functions into their own file

[Patch against drm-next.  Consider this a trial balloon for our new Linux
development model.]

This is a big chunk of code.  Separating it out makes it easier to change
without churn on the main i915_drv.c file (and there will be churn as we
fix bugs and add things like kernel mode setting).  Also makes it easier
to share this file with BSD.

Subject: drm/cred: wrap task credential accesses in the drm driver.

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

Subject: drm: Rework vblank-wait handling to allow interrupt reduction.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, drivers supporting vblank interrupt waits would run the interrupt
all the time, or all the time that any 3d client was running, preventing the
CPU from sleeping for long when the system was otherwise idle.  Now, interrupts
are disabled any time that no client is waiting on a vblank event. The new
method uses vblank counters on the chipsets when the interrupts are turned
off, rather than counting interrupts, so that we can continue to present
accurate vblank numbers.

Subject: Export shmem_file_setup for DRM-GEM

GEM needs to create shmem files to back buffer objects.  Though currently
creation of files for objects could have been driven from userland, the
modesetting work will require allocation of buffer objects before userland
is running, for boot-time message display.

Subject: Export kmap_atomic_pfn for DRM-GEM.

The driver would like to map IO space directly for copying data in when
appropriate, to avoid CPU cache flushing for streaming writes.
kmap_atomic_pfn lets us avoid IPIs associated with ioremap for this process.

Subject: drm: Add GEM ("graphics execution manager") to i915 driver.

GEM allows the creation of persistent buffer objects accessible by the
graphics device through new ioctls for managing execution of commands on the
device.  The userland API is almost entirely driver-specific to ensure that
any driver building on this model can easily map the interface to individual
driver requirements.

GEM is used by the 2d driver for managing its internal state allocations and
will be used for pixmap storage to reduce memory consumption and enable
zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

+/** @file drm_gem.c
+ *
+ * This file provides some of the base ioctls and library routines for
+ * the graphics memory manager implemented by each device driver.
+ *
+ * Because various devices have different requirements in terms of
+ * synchronization and migration strategies, implementing that is left up to
+ * the driver, and all that the general API provides should be generic --
+ * allocating objects, reading/writing data with the cpu, freeing objects.
+ * Even there, platform-dependent optimizations for reading/writing data with
+ * the CPU mean we'll likely hook those out to driver-specific calls.  However,
+ * the DRI2 implementation wants to have at least allocate/mmap be generic.
+ *
+ * The goal was to have swap-backed object allocation managed through
+ * struct file.  However, file descriptors as handles to a struct file have
+ * two major failings:
+ * - Process limits prevent more than 1024 or so being used at a time by
+ *   default.
+ * - Inability to allocate high fds will aggravate the X Server's select()
+ *   handling, and likely that of many GL client applications as well.
+ *
+ * This led to a plan of using our own integer IDs (called handles, following
+ * DRM terminology) to mimic fds, and implement the fd syscalls we need as
+ * ioctls.  The objects themselves will still include the struct file so
+ * that we can transition to fds if the required kernel infrastructure shows
+ * up at a later date, and as our interface with shmfs for memory allocation.

+ *	Let's take these a step at a time
+ *
+ *	1. Allocated
+ *		Pages allocated from the kernel may still have
+ *		cache contents, so we set them to (CPU, CPU) always.
+ *	2. Written by CPU (using pwrite)
+ *		The pwrite function calls set_domain (CPU, CPU) and
+ *		this function does nothing (as nothing changes)
+ *	3. Mapped by GTT
+ *		This function asserts that the object is not
+ *		currently in any GPU-based read or write domains
+ *	4. Read by GPU
+ *		i915_gem_execbuffer calls set_domain (COMMAND, 0).
+ *		As write_domain is zero, this function adds in the
+ *		current read domains (CPU+COMMAND, 0).
+ *		flush_domains is set to CPU.
+ *		invalidate_domains is set to COMMAND
+ *		clflush is run to get data out of the CPU caches
+ *		then i915_dev_set_domain calls i915_gem_flush to
+ *		emit an MI_FLUSH and drm_agp_chipset_flush
+ *	5. Unmapped from GTT
+ *		i915_gem_object_unbind calls set_domain (CPU, CPU)
+ *		flush_domains and invalidate_domains end up both zero
+ *		so no flushing/invalidating happens
+ *	6. Freed
+ *		yay, done
+ *
+ * Case 2: The shared render buffer
+ *
+ *	1. Allocated
+ *	2. Mapped to GTT
+ *	3. Read/written by GPU
+ *	4. set_domain to (CPU,CPU)
+ *	5. Read/written by CPU
+ *	6. Read/written by GPU
+ *
+ *	1. Allocated
+ *		Same as last example, (CPU, CPU)
+ *	2. Mapped to GTT
+ *		Nothing changes (assertions find that it is not in the GPU)
+ *	3. Read/written by GPU
+ *		execbuffer calls set_domain (RENDER, RENDER)
+ *		flush_domains gets CPU
+ *		invalidate_domains gets GPU
+ *		clflush (obj)
+ *		MI_FLUSH and drm_agp_chipset_flush
+ *	4. set_domain (CPU, CPU)
+ *		flush_domains gets GPU
+ *		invalidate_domains gets CPU
+ *		wait_rendering (obj) to make sure all drawing is complete.
+ *		This will include an MI_FLUSH to get the data from GPU
+ *		to memory
+ *		clflush (obj) to invalidate the CPU cache
+ *		Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
+ *	5. Read/written by CPU
+ *		cache lines are loaded and dirtied
+ *	6. Read written by GPU
+ *		Same as last GPU access
+ *
+ * Case 3: The constant buffer
+ *
+ *	1. Allocated
+ *	2. Written by CPU
+ *	3. Read by GPU
+ *	4. Updated (written) by CPU again
+ *	5. Read by GPU
+ *
+ *	1. Allocated
+ *		(CPU, CPU)
+ *	2. Written by CPU

+/** @file i915_gem_tiling.c
+ *
+ * Support for managing tiling state of buffer objects.
+ *
+ * The idea behind tiling is to increase cache hit rates by rearranging
+ * pixel data so that a group of pixel accesses are in the same cacheline.
+ * Performance improvement from doing this on the back/depth buffer are on
+ * the order of 30%.
+ *
+ * Intel architectures make this somewhat more complicated, though, by
+ * adjustments made to addressing of data when the memory is in interleaved
+ * mode (matched pairs of DIMMS) to improve memory bandwidth.
+ * For interleaved memory, the CPU sends every sequential 64 bytes
+ * to an alternate memory channel so it can get the bandwidth from both.
+ *
+ * The GPU also rearranges its accesses for increased bandwidth to interleaved
+ * memory, and it matches what the CPU does for non-tiled.  However, when tiled
+ * it does it a little differently, since one walks addresses not just in the
+ * X direction but also Y.  So, along with alternating channels when bit
+ * 6 of the address flips, it also alternates when other bits flip --  Bits 9
+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
+ * are common to both the 915 and 965-class hardware.
+ *
+ * The CPU also sometimes XORs in higher bits as well, to improve
+ * bandwidth doing strided access like we do so frequently in graphics.  This
+ * is called "Channel XOR Randomization" in the MCH documentation.  The result
+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
+ * decode.
+ *
+ * All of this bit 6 XORing has an effect on our memory management,
+ * as we need to make sure that the 3d driver can correctly address object
+ * contents.
+ *
+ * If we don't have interleaved memory, all tiling is safe and no swizzling is
+ * required.
+ *
+ * When bit 17 is XORed in, we simply refuse to tile at all.  Bit
+ * 17 is not just a page offset, so as we page an objet out and back in,
+ * individual pages in it will have different bit 17 addresses, resulting in
+ * each 64 bytes being swapped with its neighbor!
+ *
+ * Otherwise, if interleaved, we have to tell the 3d driver what the address
+ * swizzling it needs to do is, since it's writing with the CPU to the pages
+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
+ * to match what the GPU expects.

Subject: i915: Use struct_mutex to protect ring in GEM mode.

In the conversion for GEM, we had stopped using the hardware lock to protect
ring usage, since it was all internal to the DRM now.  However, some paths
weren't converted to using struct_mutex to prevent multiple threads from
concurrently working on the ring, in particular between the vblank swap handler
and ioctls.

Subject: drm: kill drm_device->irq

Like the last patch but adds a macro to get at the irq value instead of
dereferencing pdev directly.  Should  make things easier for the BSD guys and
if we ever support non-PCI devices.

Subject: i915: Fix up ring initialization to cover G45 oddities

G45 appears quite sensitive to ring initialization register writes,
sometimes leaving the HEAD register with the START register contents. Check
to make sure HEAD is reset correctly when START is written, and fix it up,
screaming loudly.

Subject: i915: Map status page cached for chips with GTT-based HWS location.

This should improve performance by avoiding uncached reads by the CPU (the
point of having a status page), and may improve stability.  This patch only
affects G33, GM45 and G45 chips as those are the only ones using GTT-based
HWS mappings.

Subject: i915: Don't run retire work handler while suspended

At leavevt and lastclose time, cancel any pending retire work handler
invocation, and keep the retire work handler from requeuing itself if it is
currently running.

This patch restructures i915_gem_idle to perform all of these tasks instead
of having both leavevt and lastclose call a sequence of functions.

Subject: radeon: fix PCI bus mastering support enables.

Someone noticed these registers moved around for later chips,
so we redo the codepaths per-chip. PCIE chips don't appear to
require explicit enables.

Subject: drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)

Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.

It only affects the Intel G33 series and newer.

+USB 7-Segment Numeric Display
+Manufactured by Delcom Engineering
+
+Device Information
+------------------
+USB VENDOR_ID	0x0fc5
+USB PRODUCT_ID	0x1227
+Both the 6 character and 8 character displays have PRODUCT_ID,
+and according to Delcom Engineering no queryable information
+can be obtained from the device to tell them apart.
+
+Device Modes
+------------
+By default, the driver assumes the display is only 6 characters
+The mode for 6 characters is:
+	MSB 0x06; LSB 0x3f
+For the 8 character display:
+	MSB 0x08; LSB 0xff
+The device can accept "text" either in raw, hex, or ascii textmode.
+raw controls each segment manually,
+hex expects a value between 0-15 per character,
+ascii expects a value between '0'-'9' and 'A'-'F'.
+The default is ascii.
+
+Device Operation
+----------------
+1.	Turn on the device:
+	echo 1 > /sys/bus/usb/.../powered
+2.	Set the device's mode:
+	echo $mode_msb > /sys/bus/usb/.../mode_msb
+	echo $mode_lsb > /sys/bus/usb/.../mode_lsb
+3.	Set the textmode:
+	echo $textmode > /sys/bus/usb/.../textmode
+4.	set the text (for example):
+	echo "123ABC" > /sys/bus/usb/.../text (ascii)
+	echo "A1B2" > /sys/bus/usb/.../text (ascii)
+	echo -ne "\x01\x02\x03" > /sys/bus/usb/.../text (hex)
+5.	Set the decimal places.
+	The device has either 6 or 8 decimal points.
+	to set the nth decimal place calculate 10 ** n
+	and echo it in to /sys/bus/usb/.../decimals
+	To set multiple decimals points sum up each power.
+	For example, to set the 0th and 3rd decimal place
+	echo 1001 > /sys/bus/usb/.../decimals

From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Tue, 26 Aug 2008 16:22:06 -0700
Subject: USB: add USB test and measurement class driver

This driver was originaly written by Stefan Kopp, but massively
reworked by Greg for submission.

Thanks to Felipe Balbi <me@felipebalbi.com> for lots of work in cleaning
up this driver.

Thanks to Oliver Neukum <oliver@neukum.org> for reviewing previous
versions and pointing out problems.

Subject: drivers/usb/class/usblp.c: adjust error handling code

In this code, it is possible to tell statically whether usblp will be NULL
in the error handling code.

Oliver Neukum suggested to make a goto to the final return rather than
return directly.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
identifier f,err,l,l1;
type T;
expression x,E;
statement S;
@@

x = NULL
... when != goto l1;
* x = f(...)
... when != x
err = E;
goto l;
...
* if (x != NULL)
  S
return err;
// </smpl>

Subject: USB: kill URBs permanently

looking at usb_kill_urb() it seems to me that it is unnecessarily lenient.
In the use case of disconnect() you never want to use the URB again
(for the same device) But leaving urb->reject elevated will make it easier
to avoid races between read/write and disconnect.

Subject: USB: Let some USB host controllers get IRQ flags from resource

[This version fixes a thinko in the r8a66597 driver]

This patch let a few discrete USB host controllers drivers (isp116x-hcd,
r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ
resource if configured as such, much like it's been done for the smc91x
driver.

It spares people writing support for specific boards the burden to
configure the interrupt controller independantly, and keeps all IRQ
related information in a single resource.

HCD that are integrally part of a SoC have been left aside, as there
is probably no "wiring" options...

Tested on an Xscale PXA-255 based platform with isp116x-hcd.

Subject: usb gadget: function activation/deactivation

Add a new mechanism to the composite gadget framework, letting
functions deactivate (and reactivate) themselves.  Think of it
as a refcounted wrapper for the software pullup control.

A key example of why to use this mechanism involves functions that
require a userspace daemon.  Those functions shuld use this new
mechanism to prevent the gadget from enumerating until those daemons
are activated.  Without this mechanism, hosts would see devices that
malfunction until the relevant daemons start.

 	  The Serial Gadget talks to the Linux-USB generic serial driver.

 	  "cdc-acm" driver.
 
+	  This driver also supports a CDC-OBEX option.  You will need a

+	  itself doesn't implement the OBEX protocol.
+
 	  Say "y" to link the driver statically, or "m" to build a
 	  dynamically linked module called "g_serial".
 
 	  For more information, see Documentation/usb/gadget_serial.txt

Subject: usb gadget: defer obex enumeration

Some USB peripheral controller drivers support software control
over the data pullup.  Use those controls to prevent the OBEX
function from enumerating until the userspace server has opened
the /dev/ttyGS* node it will use to implement protocol chitchat
with the USB host.

Subject: USB: drivers/usb/misc: Use an IS_ERR test rather than a NULL test

In case of error, the function backlight_device_register returns an
ERR pointer, but never returns a NULL pointer. So a NULL test that may
come after a call to this function should be strengthened by an IS_ERR
test.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@match_bad_null_test@
expression x, E;
statement S1,S2;
@@
x = backlight_device_register(...)
... when != x = E
* if (x != NULL)
S1 else S2
// </smpl>

Subject: usb: add Freescale QE/CPM USB peripheral controller driver

Some of Freescale SoC chips have a QE or CPM co-processor which
supports full speed USB.  The driver adds device mode support
of both QE and CPM USB controller to Linux USB gadget.  The
driver is tested with MPC8360 and MPC8272, and should work with
other models having QE/CPM given minor tweaks.

Subject: usb-storage: report underflow with no sense data

This patch (as1118) addresses a problem with certain USB mass-storage
devices.  These devices sometimes return less data than asked for and
then provide no sense data to explain the problem.  Currently
usb-storage leaves it up to the SCSI layer to decide how this should
be handled, and the SCSI layer interprets the lack of sense data to
mean that nothing went wrong.  But if we got less data than required
then something definitely _did_ go wrong, and we should say so.

The patch tells the SCSI layer to retry the command when this sort of
thing happens.  Retrying may not solve the underlying problem, but
it's better than believing that data was transferred when it wasn't.

Subject: OHCI: Allow broken controllers to auto-stop

This patch (as1134) attempts to improve the way we handle OHCI
controllers with broken Root Hub Status Change interrupt support.  In
these controllers the RHSC interrupt bit essentially never turns off,
making RHSC interrupts useless -- they have to remain permanently
disabled.

Such controllers should still be allowed to turn off their root hubs
when no devices are attached.  Polling for new connections can
continue while the root hub is suspended.  The patch implements this
feature.  (It won't have much effect unless CONFIG_PM is enabled and
CONFIG_USB_SUSPEND is disabled, but since the overhead is very small
we may as well do it.)

Subject: USB: ehci-dbg: increase debug buffer size for periodic file

This patch is based on the following ideas:

1. Some usb devices (such as usb video class) have endpoints of high
   interval attribute, so reading "periodic" file need more debug buffer
   to accommodate the qh or itd schedule information.  For example, 4KB
   buffer is not enough for a single interrupt qh of 2ms period.

2. print a %p need 16 byte buffer on 64-bits arch, but 8 byte on 32-bits
   arch. Add a extra bonus for 64-bits arch.

This patch fix 2 problems about reading periodic file:

1. The "..." after a interrupt qh is missed because buffer pointer is
   not moved.

2. After setting p.ptr as NULL, its next qh or itd will be omited and
   can't be stored in debug buffer.

Subject: USB: change hub initialization sleeps to delayed_work

This patch (as1137) changes the hub_activate() routine, replacing the
power-power-up and debounce delays with delayed_work calls.  The idea
is that on systems where the USB stack is compiled into the kernel
rather than built as modules, these delays will no longer block the
boot thread.  At least 100 ms is saved for each root hub, which can
add up to a significant savings in total boot time.

Arjan van de Ven was very pleased to see that this shaved 700 ms off
his computer's boot time.  Since his total boot time is on the order
of two seconds, the improvement is considerable.

Subject: usbmon: fix tiny race exposed by the fastboot patches

usbmon registers the notifier chain, takes the bus lock and then goes to
scan the existing devices for hooking up.

Unfortunately, if usb_mon gets initialized while USB bus discovery is
going on, it's possible that usbmon gets a notifier on one cpu (which runs
without USB locks), and the scan is going on and also finds the new bus,
resulting in a double sysfs registration, which then produces a WARNING.

Pete Zaitcev did the bug diagnostics on this one

Subject: MUSB: Add sanity check for maximum number of endpoints

There is no check if platform code passes in more endpoints (num_eps)
than the maximum number of enpoints (MUSB_C_NUM_EPS.)  The result is
that allocate_instance() happily writes past the end of 'struct musb'
corrupting memory.

This patch adds a BUG() if the platform code requests more than the max.

Subject: usb gadget: USB_GADGET_VBUS_DRAW Kconfig option

Offer a "how much VBUS power to request" configuration option
for USB gadgets that aren't using board-specific customization
of their gadget or (composite) configuration drivers.

Also remove a couple pointless "depends on USB_GADGET" bits
from the Kconfig text; booleans inside an "if USB_GADGET" will
already have that dependency.

Based on a patch from Justin Clacherty.

Subject: USB: Fix s3c2410_udc usb speed handling

The new composite framework revealed a weakness in the
s3c2410_udc driver gadget register function. Instead of
checking if speed asked for was USB_LOW_SPEED upon
usb_gadget_register() to deny service, it checked only
for USB_FULL_SPEED, thus denying service to usb high
speed capable gadgets (like g_ether).

Subject: musb: io: only define read/write stubs if they're not defined yet

For those archs which don't provide read/write friends we
provide our own implementation so musb driver won't break
compilation.

This is temporary fix until a better solution comes from
upstream. Idealy, <linux/io.h> would provide those calls
if the architecture did not provide them yet. In that case
being possible to remove all those stubs from musb_io.h

Subject: usb: musb_hdrc build fixes

Minor musb_hdrc updates:

  - so it'll build on DaVinci, given relevant platform updates;
      * remove support for an un-shipped OTG prototype
      * rely on gpiolib framework conversion for the I2C GPIOs
      * the <asm/arch/hdrc_cnf.h> mechanism has been removed

  - catch comments up to the recent removal of the per-SOC header
    with the silicon configuration data;

  - and remove two inappropriate "inline" declarations which
    just bloat host side code.

There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>
changes needed in this driver, catching up to the relocation
of most of the include/asm-arm/arch-* contents.

Subject: usb: musb: remove dead code from procfs

When removing the procfs file, I forgot to remove some
code that created and removed that file. Here's a patch
to fix it. Ideally this patch will be melded into the patch
removing the procfs file, don't know if it's possible still.

Sync up USB parts of the ohci-omap support in mainline with the OMAP tree.
This patch supports another first generation OMAP1 part: not just the
OMAP 1510 (and its catalog version, the OMAP 5910), but also OMAP 310.

Subject: USB: omap_udc: sync with OMAP tree

Sync up USB parts of the omap_udc support in mainline with the OMAP tree.
This patch addresses some OMAP2 differences ... there's another, with
respect to the double-buffering issue with PIO-IN in omap_ep_setup()
(which is now out of sync with the comments), but it's not clear right
now how to address that.

Subject: usb gadget: cdc ethernet notification bugfix

Bugfix for the new CDC Ethernet code:  as part of activating the
network interface's USB link, make sure its link management code
knows whether the interface is open or not.

Without this fix, the link won't work right when it's brought up
before the link is active ... because the initial notification it
sends will have the wrong link state (down, not up).  Makes it
hard to bridge these links (on the host side), among other things.

Subject: usb: vstusb.c : new driver for spectrometers used by Vernier Software
 & Technology, Inc.

This patch adds the vstusb driver to the drivers/usb/misc directory.
This driver provides support for Vernier Software & Technology
spectrometers, all made by Ocean Optics. The driver provides both IOCTL
and read()/write() methods for sending raw data to spectrometers across
the bulk channel. Each method allows for a configured timeout.

+ *  The vstusb driver supports two interfaces:

+ *
+ *  Both interfaces can be signal from other process and will abort its i/o
+ *  operation.
+ *
+ *  A timeout of 0 means NO timeout.  The user can still terminate the read via

+ *
+ *  If using multiple threads with this driver, the user should ensure that

Subject: USB: UHCI: improve scheduling of interrupt URBs

This patch (as1140) adds a little intelligence to the interrupt-URB
scheduler in uhci-hcd.  Right now the scheduler is stupid; every URB
having the same period is assigned to the same slot.  Thus a large
group of period-N URBs can fill their slot and cause -ENOSPC errors
even when all the lower-period slots are empty.

With the patch, if an URB doesn't fit in its assigned slot then the
scheduler will try using lower-period slots.  This will provide
greater flexibility.  As an example, the driver will be able to handle
more than just three or four mice, which the current driver cannot.

ehci_watchdog will wake up CPU very frequently so that CPU
stays at C3 very short, average residence time is about 50
ms on Aspire One, but we expect it should be about 1 second
or more, so this kind of periodic timer is very bad for power
saving.

We can't remove this timer because of some bad USB controller
chipset, but at least we should reduce its side effect to as
possible as low.

This patch can make CPU stay at C3 longer, average residence time
is about twice as long as original.

Please consider to apply it, thanks

Subject: USB: isp1760: Use an IS_ERR test rather than a NULL test

In case of error, the function isp1760_register returns an ERR
pointer, but never returns a NULL pointer. So after a call to this
function, a NULL test should be replaced by an IS_ERR test. Moreover,
we have noticed that:
(1) the result of isp1760_register is assigned through the function
pci_set_drvdata without an error test,
(2) if the call to isp1760_register fails, the current function
(isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM,
which seems odd.

Thus, we suggest to move the test before the call to pci_set_drvdata
to correct (1), and to turn it into a non IS_ERR test to correct (2).

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@bad_null_test@
expression x,E;
statement S1, S2;
@@
x =  isp1760_register(...)
... when != x = E
* if (x == NULL)
S1 else S2

Subject: USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.

The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be
specified in milliseconds.  The ftdi-elan driver converts milliseconds to
jiffies before passing the timeout to usb_bulk_msg().  This is mostly harmless,
since it will just lead to very long timeouts, but was obviously not the intent
of the original author.

Subject: USB: EHCI: log a warning if ehci-hcd is not loaded first

This patch (as1139) adds a warning to the system log whenever ehci-hcd
is loaded after ohci-hcd or uhci-hcd.  Nowadays most distributions are
pretty good about not doing this; maybe the warning will help convince
anyone still doing it wrong.

This patch (as1148) adds a new "snoop" message to usbfs when a device
file is opened, identifying the process responsible.  This comes in
extremely handy when trying to determine which program is doing some
unwanted USB access.

Subject: USB: EHCI: fix remote-wakeup support for ARC/TDI core

This patch (as1147) fixes the remote-wakeup support for EHCI
controllers using the ARC/TDI "embedded-TT" core.  These controllers
turn off the RESUME bit by themselves when a port resume is complete;
hence we need to keep separate track of which ports are suspended or
in the process of resuming.

The patch also makes a couple of small improvements in ehci_irq(),
replacing reads of the command register with the value already stored
in a local variable.

Subject: USB: Export if an interface driver supports autosuspend.

Create a new sysfs file per interface named supports_autosuspend.  This
file returns true if an interface driver's .supports_autosuspend flag is
set.  It also returns true if the interface is unclaimed (since the USB
core will autosuspend a device if an interface is not claimed).

This new sysfs file will be useful for user space scripts to test whether
a USB device correctly auto-suspends.

Subject: USB: hub.c: Add initial_descriptor_timeout module parameter for
 usbcore

This patch adds initial_descriptor_timeout module parameter for usbcore.ko
to allow modify initial 64-byte USB_REQ_GET_DESCRIPTOR timeout for
non-standard devices.

For example, the SATA8000 device from DATAST0R Technology Corp
requires about 10 seconds to send reply (probably it waits until
inserted disk is ready for operation).

Also, this patch adds missing usbcore parameters to
Documentation/kernel-parameters.txt.

Subject: USB: OHCI: fix endless polling behavior

This patch (as1149) fixes an obscure problem in OHCI polling.  In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:

	The interrupt handler is the only place where RHSC status
	gets turned back off;

	The interrupt handler won't turn RHSC status off because it
	doesn't turn off status flags if the corresponding interrupt
	isn't enabled;

	RHSC interrupts will never get enabled because
	ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
	status is on!

As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.

Of course, this is a bug.  The proper thing to do is to turn off RHSC
status just before reading the actual port status values.  That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on.  Possibly both, but that
won't hurt anything.

We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses.  (This re-read has to be done anyway, to post the earlier
write.)  If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.

Subject: fsl_usb2_udc: Make fsl_queue_td return type void.

fsl_queue_td always returns 0. Make it void and remove checks for non-zero
return in callers.

Subject: fsl_usb2_udc: Add a wmb before priming endpoint.

Add a wmb to fsl_queue_td before priming the endpoint. This ensures that the
modifications to the QH are seen by the hardware.

Added comment as suggested by Felipe Balbi.

Subject: fsl_usb2_udc: Fix oops on probe failure.

In some circumstances when fsl_udc_probe fails udc_controller is freed but
the pointer remains non-NULL. fsl_udc_remove will then try and teardown
the partly initialized and freed controller structure resulting in an oops.
This patch ensures udc_controller is either NULL or fully initialized after
fsl_udc_probe.

Subject: usb/fsl_qe_udc: fix response to get status request

The original code didn't respond correctly to get status request on
device and endpoint.  Although normal operations can work without the
fix.  It is not compliant with USB spec chapter9 and fails USBCV ch9
tests.  The patch fix this and a few style/typo problems.

Subject: USB: remove warn() macro from usb input drivers

USB should not be having it's own printk macros, so remove warn() and
use the system-wide standard of dev_warn() wherever possible.  In the
few places that will not work out, use a basic printk().

Subject: USB: remove warn() macro from usb net drivers

USB should not be having it's own printk macros, so remove warn() and
use the system-wide standard of dev_warn() wherever possible.  In the
few places that will not work out, use a basic printk().

Subject: USB: remove warn macro from HID core

There were two stragglers that got missed in the last merge of the HID tree that forgot to change the warn() calls to dev_warn().  This patch fixes them up.

Subject: USB: remove info() macro from usb/serial drivers

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.

From 1b29a375fb0b79a11a2d18e7bf5f6da422a35025 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>
Date: Mon, 18 Aug 2008 13:21:04 -0700
Subject: USB: remove info() macro from usb/misc drivers

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.

Subject: USB: remove info() macro from remaining usb drivers

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.  In the
few places that will not work out, use a basic printk().

Clean up the remaining usages of this in the drivers/usb/ directory.

Subject: USB: remove info() macro from usb mtd drivers

USB should not be having it's own printk macros, so remove info() and
use the system-wide standard of dev_info() wherever possible.

Subject: USB: remove use of err() in drivers/usb/serial

err() is going away, so switch to dev_err() or printk() if it's really
needed.

From 9908a32e94de2141463e104c9924279ed3509447 Mon Sep 17 00:00:00 2001
From: Greg Kroah-Hartman <gregkh@suse.de>

Subject: USB: remove err() macro from usb class drivers

USB should not be having it's own printk macros, so remove err() and
use the system-wide standard of dev_err() wherever possible.  In the
few places that will not work out, use a basic printk().
