As best I can tell, whenever retval == 0, nd->path.dentry and nd->inode
are also non-NULL. Eliminate those checks and the superfluous
audit_context check.

Pull second set of media updates from Mauro Carvalho Chehab:
"Despite its size, most of the stuff here is trivial. This series
contains:
- s5p-mfc: additions at the driver and at the core to support H.264
hardware codec;
- Some improvements at s5p and davinci embedded drivers;
- Some V4L2 compliance fixes applied on a few drivers;
- Several random trivial patches, including several fixes and a few
new board support additions;
Notes:
1) Some Exynos media patches were dependent on some -arm fixes that
got merged on changeset 782cd9e. That's why this pull request is
based that changeset.
2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull second set of pinctrl patches from Linus Walleij:
"Here is a late pinctrl pull request with stuff that wasn't quite
tested at the first pull request.
The main reason to not hold off is that the modifications to
irq_domain_add_simple() as reviewed by Rob Herring introduce new
infrastructure for irqdomains that will be useful for the next cycle:
instead of sprinkling irq descriptor allocation all over the kernel
wherever a "legacy" domain is registered, which is necessary for any
platform using sparse IRQs, and many irq chips are say GPIO
controllers which may be used with several systems, some with sparse
IRQs some not, we push this into the irq_domain_add_simple() so we can
atleast do mistakes in one place.
The irq_domain_add_simple() is currently unused in the kernel, so I
need to provide a user. The Nomadik stuff that goes with are changes
to the driver I use day-to-day to make use of this facility (and a
dependency), so see it as a way to eat my own dogfood: if this blows
up the egg hits my face.
A second round of pinctrl patches for v3.7:
- Complement the Nomadik pinctrl driver with alternate Cx functions
so it handles all oddities.
- A patch to the IRQdomain to reform the simple irqdomain to handle
IRQ descriptor allocation dynamically.
- Use the above feature in the Nomadik pin controller."

Pull writeback fixes from Fengguang Wu:
"Three trivial writeback fixes"
* 'writeback-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wfg/linux:
CPU hotplug, writeback: Don't call writeback_set_ratelimit() too often during hotplug

backing-dev: use kstrto* in preference to simple_strtoul

Most of them never returned anyway - only two functions had to be
changed. That allows to simplify their callers a whole lot.
Note that this does *not* apply to kthread_run() callbacks - all of
those had been called from the same kernel_thread() callback, which
did do_exit() already. This is strictly about very few low-level
kernel_thread() callbacks (there are only 6 of those, mostly as part
of kthread.h and kmod.h exported mechanisms, plus kernel_init()
itself).

The only place where kernel_execve() is called without a way to
return to the caller of kernel_thread() callback is kernel_post().
Reorganize kernel_init()/kernel_post() - instead of the former
calling the latter in the end (and getting freed by it), have the
latter *begin* with calling the former (and turn the latter into
kernel_thread() callback, of course).

Turn the slow side of work_pending into C function, including all
the looping. What we get out of that:
* we do _not_ call get_signal_to_deliver() with IRQs disabled
anymore
* no need to save/restore volatiles on each pass if there
turns to be more than one (unlikely, but still)
* all double-restart prevention is in C now.
* glue gets simpler.

In case we have both NEED_RESCHED and SIGPENDING/NOTIFY_RESUME,
handle the latter first. We'll get to original priorities in
the next commit, but now that allows to simplify the treatment
of NEED_RESCHED-only case nicely. Namely, now there no need to
preserve the data for restarts across the call of schedule() in
$work_resched; we can get there only if we had either returned
from syscall without SIGPENDING (in which case we should've
had no restart-worthy return value and want no restarts) or
already got through do_notify_resume() call (in which case we
want no restarts anymore). So we can just slap 0 into $19
instead of preserving it (and $20).

The follow_link() function always initializes its *p argument,
or returns an error, but when building with 'gcc -s', the compiler
gets confused by the __always_inline attribute to the function
and can no longer detect where the cookie was initialized.
The solution is to always initialize the pointer from follow_link,
even in the error path. When building with -O2, this has zero impact
on generated code and adds a single instruction in the error path
for a -Os build on ARM.
Without this patch, building with gcc-4.6 through gcc-4.8 and
CONFIG_CC_OPTIMIZE_FOR_SIZE results in:
fs/namei.c: In function 'link_path_walk':

This is not very likely to happen though, because p9_write_work()

But this also means that taking the lock earlier will not be costly.

This patch adds #ifdef __KERNEL__ guards around the COMPAT_* definitions
to avoid exporting them to user. AArch32 user requiring the kernel
headers must use those generated with ARCH=arm.

This patch only includes asm/unistd32.h where necessary and removes its
inclusion in the asm/unistd.h file. The __SYSCALL_COMPAT guard is
dropped.

This patch removes the compat __NR_* definitions from the unistd32.h
file and only keeps those that are used by the AArch64 kernel with a new
__NR_compat_* prefix. The additional wrapper definitions in
arch/arm64/kernel/sys32.S have been removed and the actual wrapper names
included in the asm/unistd32.h file.

Now that IRQ domains are in use, we should be acting on domain-local
IRQ numbers (hwirq) instead of 'global' ones.
