Use a naming based on vtime as a prefix for virtual based
cputime accounting APIs:
- account_system_vtime() -> vtime_account()
- account_switch_vtime() -> vtime_task_switch()
It makes it easier to allow for further declension such
as vtime_account_system(), vtime_account_idle(), ... if we
want to find out the context we account to from generic code.
This also make it better to know on which subsystem these APIs
refer to.

If __pevent_parse_format() succeeded but add_event() failed, 'ret' didn't
have a proper error code. Set it to PEVENT_ERRNO__MEM_ALLOC_FAILED.
In addition, at that point 'event' also has fields and format
information and they all need to be freed. Call pevent_free_format() to
handle it.

When the bindings for the TPS6586x regulator were being proposed, I
asserted that DT node naming rules for bus child nodes should also be
applied to nodes inside the TPS6586x regulator node itself. In other
words, that each node providing regulator init data should be named
after the type of object it represented ("regulator") and hence that
some other property was required to indicate which regulator the node
described ("regulator-compatible"). In turn this led to multiple nodes
having the same name, thus requiring node names to use a unit address
to make them unique, thus requiring reg properties within the nodes and
However, subsequent discussion indicates that the rules I was asserting
only applies to standardized bus nodes, and within a device's own node,
the binding can basically do anything sane that it wants.
Hence, this change deprecates the register-compatible property, and
instead uses node names to replace this functionality. This greatly
simplifies the device tree content, making them smaller and more legible.
The code is changed such that old device trees continue to work.

Sandy bridge EDAC is calculating the memory size with overflow.
Basically, the size field and the integer calculation is using 32 bits.
More bits are needed, when the DIMM memories have high density.
The net result is that memories are improperly reported there, when
high-density DIMMs are used:
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 0, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 1, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
As the number of pages value is handled at the EDAC core as unsigned
ints, the driver shows the 16 GB memories at sysfs interface as 16760832
MB! The fix is simple: calculate the number of pages as unsigned 64-bits
integer.
After the patch, the memory size (16 GB) is properly detected:
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 0, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800

Some drivers need to switch pin states between GPIO and pin function at
runtime, which was inadvertently broken in the pinctrl driver for GPIOs
being bound to a specific direction.
This fixes up the request path to ensure that previously configured GPIOs
don't cause us to inadvertently error out with an unsupported mux on
reconfig, which in practice is primarily aimed at trapping pull-up/down
users that have yet to be implemented under the new API.
Fixes up regressions in the TPU PWM driver, amongst others.

John W. Linville says:
====================
Please pull this last(?) batch of fixes intended for 3.6...
For the Bluetooth bits, Gustavo says this:
"Here goes probably my last update to 3.6. It includes the two patches
you were ok last week(from Andrzej Kaczmarek), those are critical
ones, and two other fixes one for a system crash and the other for
a missing lockdep annotation."
The referenced fixes from Andrzej prevent attempts to configure devices
that are powered-off.
Along with the Bluetooth fixes, there are a couple of 802.11 fixes.
Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an
interrupt twice. Luis R. Rodriguez provides a fix for a possible
circular lock dependency in the cfg80211 regulatory enforcement code.
All of these have been in linux-next for a few days. I hope they are
not too late to make the 3.6 release!

It is OK to disable the PV guest from accessing NUMA data as right now
we do not inject any NUMA node information to the PV guests. When we

Commit 0d52f54e2ef64c189dedc332e680b2eb4a34590a (PCI / ACPI: Make acpiphp
ignore root bridges using PCIe native hotplug) added code that made the
acpiphp driver completely ignore PCIe root complexes for which the kernel
had been granted control of the native PCIe hotplug feature by the BIOS
through _OSC. Later commit 619a5182d1f38a3d629ee48e04fa182ef9170052
"PCI hotplug: Always allow acpiphp to handle non-PCIe bridges" relaxed
the constraints to allow acpiphp driver handle non-PCIe bridges under
such a complex. The constraint needs to be relaxed further to allow
acpiphp driver to handle PCIe ports without native PCIe hotplug capability.
Some MR-IOV switch chipsets, such PLX8696, support multiple virtual PCIe
switches and may migrate downstream ports among virtual switches. To
migrate a downstream port from the source virtual switch to the target, the
port needs to be hot-removed from the source and hot-added into the target.
The pciehp driver can't be used here because there are no slots within the
virtual PCIe switch. So acpiphp driver is used to support downstream port
migration. A typical configuration is as below:
[Root without native PCIe HP]
[Upstream port of vswitch without native PCIe HP]
[Downstream port of vswitch with native PCIe HP]
[PCIe endpoint]
Here acpiphp driver will be used to handle root ports and upstream port
in the virtual switch, and pciehp driver will be used to handle downstream
ports in the virtual switch.

This patch changes the function signature of walk_root_bridge().
We can omit _STA, _SEG, and _BBN evaluation by passing not acpi_handle
but acpi_pci_root. Now that acpi_pci_slot_add() which is the only
caller of walk_root_bridge() gets acpi_pci_root structure, changing
signature of walk_root_bridge() is reasonable.

This patch changes .add/.remove interfaces of acpi_pci_driver.
In the current implementation acpi_handle is passed as a parameter
of .add/.remove interface. However, the acpi_pci_root structure
contains more useful information than just the acpi_handle. This
enables us to avoid some useless lookups in each acpi_pci_driver.
Note: This changes interfaces used by acpi_pci_register_driver(), an
exported symbol. This patch updates all the in-kernel users, but any
out-of-kernel acpi_pci_register_driver() users will need updates.

The KSZ8021 PHY was previously caught by KS8051, which is not correct.
This PHY needs additional setup if it is strapped for address 0. In such
case an reserved bit must be written in the 0x16, "Operation Mode Strap
Override" register. According to the KS8051 datasheet, that bit means
"PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021.
The issue where the ethernet controller (Freescale FEC) did not communicate
with network is fixed by writing this bit as 1.

when __ARCH_HAS_VGA_DEFAULT_DEVICE is not defined, aka EFIFB is not used,
for static path, vga_default setting is through vga_arbiter_add_pci_device.
and later x86 pci_fixup_video, will skip setting again.
- subsys_initcall(vga_arb_device_init) come first to call
vga_arbiter_add_pci_device. It will call pci_get_dev to hold one reference.
for hotplug add path, even vga_arbiter_add_pci_device is called via
notifier, but it will check VGA_RSRC_LEGACY_MASK that is not set for
hotplug path. So x86 pci_fixup_video will take over to call
vga_set_default_device(). It will not hold one refrence.
Later for hotplug remove path, vga_arbiter_del_pci_device that does not
check VGA_RSRC_LEGACY_MASK will call put_device and it will cause ref_count
to decrease extra. that will have that pci device get deleted early
wrongly.

This patch splits trace event initialization in two stages:
* ftrace enable
* sysfs event entry creation
This allows to capture trace events from an earlier point
by using 'trace_event' kernel parameter and is important
to trace boot-up allocations.
Note that, in order to enable events at core_initcall,
it's necessary to move init_ftrace_syscalls() from
core_initcall to early_initcall.
