msm: camera: Avoid memory corruption by changing order of enum

SET_POSITION is added above MOVE_FOCUS which makes kernel prone to
memory corruption as MOVE_FOCUS enum is changed. when CFG_POSITION
is not present and userspace calls MOVE_FOCUS kernel misinterprets
MOVE_FOCUS as SET_POSITION and thus copies user structure to wrong
structure and makes memory to corrupt.

msm: mdss: remove interruptible timeout waits

Currently display driver contexts are not utilizing interruptible
wake-ups while using wait_for_completion_interruptible_timeout. This
can lead to incorrect context wake-up and un-predictable outcome. Since
there is already a timeout attached to these kind of context sleeps, it
is safe to replace them with wait_for_completion_timeout.

msm: kgsl: Allow GPU start to run in a high priority queue

The GPU start sequence needs to run with low latency when coming
out of slumber for the first draw command. For those cases allow the
start function to be queued into a high priority workqueue to reduce
the chance of it getting scheduled out.

msm: kgsl: Add an input handler to power up the GPU on a touch event

On a device where the primary input is a touchscreen nobody is
surprised that touch events are often the catalyst for drawing
frames. If the GPU is in slumber we can get a jump on the action
by watching for touch events and turning the GPU on in anticipation
of a draw call. Register for events from all input drivers
returning EV_ABS events and queue a work task to power up the GPU
if it is currently in slumber.

2fs: fix wrong statistics of inline data
If we remove a file that has inline data after mount, our statistics turns to
inaccurate.

cat /sys/kernel/debug/f2fs/status
  - Inline_data Inode: 4294967295

Let's add stat_inc_inline_inode() to stat inline info of the file when lookup.

Change log from v1:
 o stat in f2fs_lookup() instead of in do_read_inode() for excluding wrong stat.

tcp: add a sysctl to config the tcp_default_init_rwnd

The default initial rwnd is hardcoded to 10.

Now we allow it to be controlled via
  /proc/sys/net/ipv4/tcp_default_init_rwnd
which limits the values from 3 to 100

This is somewhat needed because ipv6 routes are
autoconfigured by the kernel.

See "An Argument for Increasing TCP's Initial Congestion Window"
in https://developers.google.com/speed/articles/tcp_initcwnd_paper.pdf

msm: vidc: return EBUSY when hw is overloaded

Component reports hw error to client immediately in
the same thread after stream on failure and blocks
subsequence errors to client. Therefore, the async
v4l2 event "V4L2_EVENT_MSM_VIDC_HW_OVERLOAD" will
be ignored in component.
When loading resource fails because of hw
overload, instead of sending V4l2 event, we are
going to return EBUSY and this return value will
be checked in userspace.
