em28xx-dvb, em28xx-alsa and em28xx-ir are typically initialized
asyncrhronously. The exception for it is when those modules
are loaded before em28xx (or before an em28xx card insertion) or
when they're built in.
Make the extentions to always load asynchronously. That allows
having all DVB firmwares loaded synchronously with udev-182.
Antti tested it with the following hardware:
Hauppauge WinTV HVR 930C
MaxMedia UB425-TC
PCTV QuatroStick nano (520e)

Pull sparc updates from David Miller:
"Largely this is simply adding support for the Niagara 4 cpu.
Major areas are perf events (chip now supports 4 counters and can
monitor any event on each counter), crypto (opcodes are availble for
sha1, sha256, sha512, md5, crc32c, AES, DES, CAMELLIA, and Kasumi
although the last is unsupported since we lack a generic crypto layer
Kasumi implementation), and an optimized memcpy.
Finally some cleanups by Peter Senna Tschudin."

if the configuration option 'delay_cal' is set, delay both IR & RF
calibration until init() is called.
both module option 'cal' or configuration option 'rf_cal_on_startup'
will override this delay. it makes no sense to mix 'delay_cal' with
'rf_cal_on_startup' as these options conflict with each other.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
"This is a mostly modest set of changes to enable basic user namespace
support. This allows the code to code to compile with user namespaces
enabled and removes the assumption there is only the initial user
namespace. Everything is converted except for the most complex of the
filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,
nfs, ocfs2 and xfs as those patches need a bit more review.
The strategy is to push kuid_t and kgid_t values are far down into
subsystems and filesystems as reasonable. Leaving the make_kuid and
from_kuid operations to happen at the edge of userspace, as the values
come off the disk, and as the values come in from the network.
Letting compile type incompatible compile errors (present when user
namespaces are enabled) guide me to find the issues.
The most tricky areas have been the places where we had an implicit
union of uid and gid values and were storing them in an unsigned int.
Those places were converted into explicit unions. I made certain to
handle those places with simple trivial patches.
Out of that work I discovered we have generic interfaces for storing
quota by projid. I had never heard of the project identifiers before.
Adding full user namespace support for project identifiers accounts
for most of the code size growth in my git tree.
Ultimately there will be work to relax privlige checks from
"capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing
root in a user names to do those things that today we only forbid to
non-root users because it will confuse suid root applications.
While I was pushing kuid_t and kgid_t changes deep into the audit code
I made a few other cleanups. I capitalized on the fact we process
netlink messages in the context of the message sender. I removed
usage of NETLINK_CRED, and started directly using current->tty.
Some of these patches have also made it into maintainer trees, with no
problems from identical code from different trees showing up in
linux-next.
After reading through all of this code I feel like I might be able to
win a game of kernel trivial pursuit."

Pull cgroup hierarchy update from Tejun Heo:
"Currently, different cgroup subsystems handle nested cgroups
completely differently. There's no consistency among subsystems and
the behaviors often are outright broken.
People at least seem to agree that the broken hierarhcy behaviors need
to be weeded out if any progress is gonna be made on this front and
that the fallouts from deprecating the broken behaviors should be
acceptable especially given that the current behaviors don't make much
sense when nested.
This patch makes cgroup emit warning messages if cgroups for
subsystems with broken hierarchy behavior are nested to prepare for
fixing them in the future. This was put in a separate branch because
more related changes were expected (didn't make it this round) and the
memory cgroup wanted to pull in this and make changes on top."

Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.
The changes made in this commit are:
(1) Exported generated files (of which there are currently four) are moved to
uapi/ directories under the appropriate generated/ directory, thus we
get:
include/generated/uapi/linux/version.h
arch/x86/include/generated/uapi/asm/unistd_32.h
arch/x86/include/generated/uapi/asm/unistd_64.h
arch/x86/include/generated/uapi/asm/unistd_x32.h
These paths were added to the build as -I flags in a previous patch.
(2) scripts/Makefile.headersinst is now given the UAPI path to install from
rather than the old path.
It then determines the old path from that and includes that Kbuild also
if it exists, thus permitting the headers to exist in either directory
during the changeover.
I also renamed the "install" variable to "installdir" as it refers to a
directory not the install program.
(3) scripts/headers_install.pl is altered to take a list of source file paths
instead of just their names so that the makefile can tell it exactly
where to find each file.
For the moment, files can be obtained from one of four places for each
output directory:
.../include/uapi/foo/
.../include/generated/uapi/foo/
.../include/foo/
.../include/generated/foo/
The non-UAPI paths will be dropped later.

Set up uapi/asm/Kbuild.asm. This requires the mandatory headers to be
dynamically detected. The same goes for include/asm/Kbuild.asm. The problem
is that the header files will be split or moved one at a time, but each header
file in Kbuild.asm's list applies to all arch headers of that name
simultaneously.
The dynamic detection of mandatory files can be undone later.

crop->which is already validated when subdev set_crop and get_crop
callbacks are called from within the v4l2-core. If it ever happens
the crop operations are called directly for some reason in kernel
space, with incorrect crop->which argument, just log it with WARN

Partition the header include path flags into two sets, one for kernelspace
builds and one for userspace builds.
Add the following directories to build after the ordinary include directories
so that #include will pick up the UAPI header directly if the kernel header
has been moved there.
The userspace set (represented by the USERINCLUDE make variable) contains:
-I $(srctree)/arch/$(hdr-arch)/include/uapi
-I arch/$(hdr-arch)/include/generated/uapi
-I $(srctree)/include/uapi
-I include/generated/uapi
-include $(srctree)/include/linux/kconfig.h
and the kernelspace set (represented by the LINUXINCLUDE make variable)
contains:
-I $(srctree)/arch/$(hdr-arch)/include
-I arch/$(hdr-arch)/include/generated
-I $(srctree)/include
-I include --- if not building in the source tree
plus everything in the USERINCLUDE set.
Then use USERINCLUDE in building the x86 boot code.

because the DRM code relies on specific -I flags to make #include "..." work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

Only refer to the DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h) from
within drmP.h and drm_crtc.h, and use #include <...> to refer to them so that
when the UAPI split happens they can still be accessed.

All code setting/clearing working context bits has been moved
to separate functions. set_bit/clear_bit have been replaced by
non-atomic variants - variable is already guarded by spin_lock.

s5p-mfc encoder after receiving V4L2_ENC_CMD_STOP command
will instruct MFC device to release all encoded frames.
After dequeuing last encoded frame driver will generate
V4L2_EVENT_EOS event.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

xen_init_IRQ should be marked __init because it calls other functions
marked __init and is always called by functions marked __init (on both
x86 and arm).
Also remove the unused EXPORT_SYMBOL_GPL(xen_init_IRQ).
Both changes were introduced by "xen/arm: receive Xen events on ARM".
