In https://bugs.archlinux.org/task/27996, failure of driver r8712u is
reported, with a timeout during module loading due to synchronous loading
of the firmware. The code now uses request_firmware_nowait().

737912e11b staging: usbip: fix to prevent potentially using uninitialized spinlock
The stub_probe function can be called as soon as the stub_driver is
registered. This can lead to the busid_table_lock being used before it
is initialized. Moved calling the init_busid_table function (which
initalizes this spinlock) to be called earlier in the init function to
prevent this from happening.

4c0029f01f staging: r8712u: Fix problem when CONFIG_R8712_AP is set
When this driver was upgraded to the vendor 20100831 version in
commit 93c55dda09 et al,, one listhead initialization was missed.
This broke complete operation of the driver whenever AP mode was
enabled.

This patch fixes https://bugs.archlinux.org/task/27996.

5a63177a69 staging: tidspbridge: fix bridge_open memory leaks
There are two members of pr_ctxt allocated during bridge_open that
are never freed resulting in memory leaks, these are stream_id and
node_id, they are now freed on release of the handle (bridge_release)
right before freeing pr_ctxt.

Error path for bridge_open was also fixed since the same variables
could result in memory leaking due to missing handling of failure
scenarios. While at it, the indentation changes were introduced to
avoid interleaved goto statements inside big if blocks.

bd1eff9741 Staging: android: binder: Fix crashes when sharing a binder file between processes
Opening the binder driver and sharing the file returned with
other processes (e.g. by calling fork) can crash the kernel.
Prevent these crashes with the following changes:
- Add a mutex to protect against two processes mmapping the
  same binder_proc.
- After locking mmap_sem, check that the vma we want to access
  (still) points to the same mm_struct.
- Use proc->tsk instead of current to get the files struct since
  this is where we get the rlimit from.

e8b4553457 zcache: Set SWIZ_BITS to 8 to reduce tmem bucket lock contention.
SWIZ_BITS > 8 results in a much larger number of "tmem_obj"
allocations, likely one per page-placed-in-frontswap.  The
tmem_obj is not huge (roughly 100 bytes), but it is large
enough to add a not-insignificant memory overhead to zcache.

The SWIZ_BITS=8  will get roughly the same lock contention
without the space wastage.

The effect of SWIZ_BITS can be thought of as "2^SWIZ_BITS is
the number of unique oids that be generated" (This concept is
limited to frontswap's use of tmem).

9256a4789b zcache: fix deadlock condition
I discovered this deadlock condition awhile ago working on RAMster
but it affects zcache as well.  The list spinlock must be
locked prior to the page spinlock and released after.  As
a result, the page copy must also be done while the locks are held.

Applies to 3.2.  Konrad, please push (via GregKH?)...
this is definitely a bug fix so need not be pushed during
a -rc0 window.

9a0774e099 staging: drm/omap: multiplanar and YUV support
Add support in framebuffer objects for other color formats and multi-
planar YUV (NV12).  Since this requires changing the API between the
plane and fb for getting scanout information (paddr, etc), take
advantage of the opportunity and put in place a way to allow fb's to
be unpinned when they are not being scanned out.  Now, before start
of scanout the plane calls omap_framebuffer_pin() which takes care
to pin all the backing bo's, then omap_framebuffer_update_scanout()
however many times to update the scanout address(es), etc, and then
when finished omap_framebuffer_unpin().

bb5c2d9aaa staging: drm/omap: add drm_plane support
Because framebuffer layer and overlay scanout video pipes are basically
thing in OMAP display subsystem (the only difference being that the first
video pipe does not support scaling or YUV formats), much of the CRTC
code is pulled into the plane implementation, and a private plane object
is used by the CRTC object.  This avoids code duplication between the
plane and CRTC.

ff4b8a57f0 Merge branch 'driver-core-next' into Linux 3.2
This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.

The microcode_core.c patch was provided by Stephen Rothwell
<sfr@canb.auug.org.au> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

eabd0eaf4f [media] drivers/staging/media/as102/as102_usb_drv.c: shift position of allocation code
The conditional after the kzalloc says that the tested expression should
never be true, but if it were, the allocated data would have to be freed.
This change just moves the allocation below the test, to avoid any
possibility of the problem.

A simplified version of the semantic match that finds the problem is as
follows: (http://coccinelle.lip6.fr)

// <smpl>
@r exists@
local idexpression x;
statement S;
identifier f1;
position p1,p2;

 return \(0\|<+...x...+>\|ptr\);

527f18be2d [media] Staging: dt3155v4l: update to newer API
I changed the function definitions for dt3155_queue_setup() to match the
newer API.  The dt3155_start_streaming() function didn't do anything so
I just removed it.

This silences the following gcc warnings:

6225f18b88 [media] Don't test for ops->info.type inside drivers
Now, ops->info.type is handled inside the dvb_frontend
core, only for DVBv3 calls, and according with the
delivery system. So, drivers should not care or use it,
otherwise, it may have issues with DVBv5 calls.

The drivers that were still using it were detected via
this small temporary hack:

6b520e0565 vfs: fix the stupidity with i_dentry in inode destructors
Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else.  Not to mention the removal of
boilerplate code from ->destroy_inode() instances...
