Only code move, no functional change.
Main reason to do this was to get rid of the warnings:
drivers/gpio/gpio-samsung.c: In function 'samsung_gpiolib_init':
drivers/gpio/gpio-samsung.c:2974:1: warning: label 'err_ioremap4' defined but not used [-Wunused-label]
drivers/gpio/gpio-samsung.c:2722:47: warning: unused variable 'gpio_base4' [-Wunused-variable]
without adding more ifdef mess.
I think this whole file would do well being coverted over to a platform
driver and moving most of the tables out to SoC code and/or device trees,
but since that changes init ordering it needs to be done with some care,
i.e. not at this time.

Commit bc3e53f682 ("mm: distinguish between mlocked and pinned

the IB stack. However, in ib_umem_get() the pinned counter is
incremented, but ib_umem_release() wrongly decrements the locked
counter. Fix this.

This teq was first introduced in bcc0f6a ([ARM] msm: clean up
iomap and devices, 2008-09-10). It seems that DEBUG_LL support on
MSM at the time had to remove the virtual mapping for the uart
base. Thus when the MMU was enabled the addruart macro returned 0
and the senduart macro would test for 0 and do nothing. It was a
simple way to turn off DEBUG_LL when the MMU was enabled.
The virtual mapping was added back in 6339f66 (msm: make
debugging UART (for DEBUG_LL) configurable, 2009-11-02) but the
patch forgot to remove the teq here. So as it stands the teq has
been useless for two years and DEBUG_LL works fine without it.

barrier: Reduce the amount of disturbance by rcu_barrier() to the rest of
the system. This branch also includes improvements to
RCU_FAST_NO_HZ, which are included here due to conflicts.
fixes: Miscellaneous fixes.
inline: Remaining changes from an abortive attempt to inline
preemptible RCU's __rcu_read_lock(). These are (1) making
exit_rcu() avoid unnecessary work and (2) avoiding having
preemptible RCU record a blocked thread when the scheduler
declines to do a context switch.
srcu: Lai Jiangshan's algorithmic implementation of SRCU, including
call_srcu().
In the PCM read/write loop, the driver calls snd_pcm_update_hw_ptr()
at each time at the beginning of the loop. Russell King reported that
this hogs CPU significantly.
The current code assumes that the pointer callback is very fast and
cheap, also not too much fine grained. It's not true in all cases.
When the pointer advances short samples while the read/write copy has
been performed, the driver updates the hw_ptr and gets avail > 0
again. Then it tries to read/write these small chunks. This repeats
until the avail really gets to zero.
For avoiding this situation, a simple workaround is to call
snd_pcm_update_hw_ptr() only once at starting the loop, assuming that
the read/write copy is performed fast enough. If the available count
becomes short, it goes to snd_pcm_wait_avail() anyway, and this
processes right.

- sparse fixes from Ben.
- tons of little cleanups from Chris all over: tiling_changed
clarification, deferred_free list removal, ...
- fix up irq handler on gen2 & gen3 + related cleanups from Chris
- prep work for wait_rendering_timeout from Ben with some nice
refactorings
- first set of infoframe fixes from Paulo for doubleclocked CEA modes
- improve pch pll handling from Jesse and Chris
- gpu hangman, this also contains the reset fix for gen4
- rps sanity check from Chris - this papers over issues when the gpu fails
to clock up on snb/ivb, and it is shockingly easy to hit. The code
prints a big WARN backtrace and restores the hw to a sane state. The
real fix is still in the works.
Atm I'm aware of 2 regressions in -next:
- One of the gmbus patches (not gmbus itself) regressed lvds detection on
a MacbookPro. I've analyzed the bug already and I think I know what's
going on, patch is awaiting test feedback.
- Just today QA reported that DP on ilk regressed. That bug is fresh of
the press and still awaiting detailed logfiles and the bisect result.
The only thing that's clear atm is that -fixes works and -next doesn't.
Previously these functions would assume that vma->vm_file was the
drm_file. Although if in some cases if the drm driver needs to use
something else for the backing file (such as the tmpfs filp) then this
assumption is no longer true. But vma->vm_private_data is still the
GEM object.
With this change, now the drm_device comes from the GEM object rather
than the drm_file so the driver is more free to play with vma->vm_file.
The scenario where this comes up is for mmap'ing of cached dmabuf's
for non-coherent systems, where the driver needs to use fault handling
and PTE shootdown to simulate coherency. We can't use the vma->vm_file
of the dmabuf, which is using anon_inode's address_space. The most
straightforward thing to do is to use the GEM object's obj->filp for
vma->vm_file in all cases, for which we need this patch.

[ 43.106311] loop0: rw=0, want=277470, limit=2774
Squashfs manages to read in the end block(s) of the disk during the
mount operation. Then, when dd reads the block device, it leads to
block_read_full_page being called with buffers that are beyond end of
disk, but are marked as mapped. Thus, it would end up submitting read
I/O against them, resulting in the errors mentioned above. I fixed the
problem by modifying init_page_buffers to only set the buffer mapped if
it fell inside of i_size.
Cheers,
Jeff

The variables 'StatusProcEntry' and 'UserCommandProcEntry' are
assigned to once and then never used. This patch gets rid of the
variables.
While I was there I also fixed the indentation of the function to use
tabs rather than spaces for the lines that did not already do so.

Mike Turquette <mturquette@ti.com> has asked me to take the clock
changes through the arm-soc tree while there are still so many
inderdependencies, so this is the entire branch.

On big-endian systems (e.g., Apple PowerBook), trying to use a
logitech wireless mouse with the Logitech Unifying Receiver does not
work with v3.2 and later kernels. The device doesn't show up in
/dev/input. Older kernels work fine.
That is because the new hid-logitech-dj driver claims the device. The
device arrival notification appears:
20 00 41 02 00 00 00 00 00 00 00 00 00 00 00
and we read the report_types bitfield (02 00 00 00) to find out what
kind of device it is. Unfortunately the driver only reads the first 8
bits and treats that value as a 32-bit little-endian number, so on a
powerpc the report type seems to be 0x02000000 and is not recognized.
Even on little-endian machines, connecting a media center remote
control (report type 00 01 00 00) with this driver loaded would
presumably fail for the same reason.
Fix both problems by using get_unaligned_le32() to read all four
bytes, which is a little clearer anyway. After this change, the
wireless mouse works on Hugo's PowerBook again.
Based on a patch by Nestor Lopez Casado.

Add sysfs attribute to control LED selector on Wacom Intuos4. There are 4
different LEDs on the tablet and they can be turned on by something like:
echo 50 > /sys/class/leds/(device # here)\:selector\:1/brightness
Only one can be lit at a time. The brightness range is 0 to 127. This patch
also contains short ABI description.

Implement the DSS device driver audio support interface in the HDMI
panel driver and generic driver. The implementation relies on the
IP-specific functions that are defined at DSS probe time.
A mixed locking strategy is used. The panel's mutex is used when
the state of the panel is queried as required by the audio functions.
The audio state is protected using a spinlock as users of DSS HDMI
audio functionality might start/stop audio while holding a spinlock.
The mutex and the spinlock are held and released as needed by each
individual function to protect the panel state and the audio state.
Although the panel's audio_start functions does not check whether
the panel is active, the audio _ENABLED state can be reached only
from audio_enable, which does check the state of the panel. Also,
if the panel is ever disabled, the audio state will transition
to _DISABLED. Transitions are always protected by the audio lock.

As the hdmi_lock mutex is inside the hdmi struct, rename to simply
"lock". This is only a change in the name. There are not changes
in functionality.
