msm: display: maintain smmu for secure video

Currently video maps and unmaps the secure memory.
It could be too early to unmap it.
Rotator and MDP will maintain this, only unmap it when
no more needed. Memory managr has a refence count for it.

msm: rotator: sync point support

Add MSM_ROTATOR_IOCTL_BUFFER_SYNC ioctl interface.
Rotator will create a timeline for each session at START, wait for
input fence and create released fence in this ioctl call,
signal the timeline after rotation is done.

msm: kgsl: Don't change the sglen of the memdesc if allocation fails

If the page_alloc loop fails, we changed the length of the scatterlist
for the memdesc to the last good page so we could have an efficient
loop through kgsl_sharedmem_free.  Unfortunately, we were also using
the sglen to decide between using kmem or vmalloc memory for the sg
list in the first place. There is a chance that one could start out
with a large sg list from vmalloc, but if it failed early, then we
could truncate the size and attempt to kfree it.

Zero the stlist at init time and use a length == 0 as an indicator
that the list might be truncated.

msm: display: increase fence timeout

Increase timeout value to 900ms to allow
gfx engine to render longer.
When sync_fence_wait fails, need not put fence as
it will be handled outside the loop.

msm_fb: Update MDP fence wait behaviour

The current fence wait times out too early in cases where the GPU
is under a heavy workload. Change this behaviour to warn and wait
for a longer time for GPU to complete it's work.

msm_fb: Add support for multiple DCS commands in a single tx

This patch adds support to send multiple DCS commands in a
single transaction. This helps to reduce the latency caused by
separate tx for each DCS command. The turnaround time
caused by the wait for one DSI interrupt for each transaction
is reduced with this.

msm_fb: display: fix fence fd list be put twice

msm_fb_wait_for_fence() will put fence fd list if sync_fence_wait()
failed. After that same fd list wil be put one more time. This
cause a fd put twice and cause system crash at the time fd
was closed.

gpu: ion: suppress excessive logging for expected failure cases

We expect alloc_pages to fail for high-order pages under stressed
memory conditions. It should then fall back to lower-order page
allocations but due to excessive logging the system crashes. Use
__GFP_NOWARN for high-order allocations to avoid excessive logging.

msm_fb: display: fix the suspend/resume hang caused by wait4vsync stuck

wait_for_completion in wait4vsync stucks after multiple suspend/resume
tests. The cause is that when show_event timeout happens, or vsync isr
is disabled for long time, wait_vsync_cnt resets to zero, and in vsync
isr complete_all has no chance to be called which caused mdp hang. So
complete_all needs to be called whenever show_event has timeouts.
