msm: vidc: Send ABORT in FLUSH command from the Client

When session error is sent to the client, client issues FLUSH
and release buffers commands. But as instance state is INVALID,
these commands are never sent to the firmware, instead FLUSH
DONE and Release buffer done are sent back to client even
though firmware might be working on these buffers which may
result into page faults.
This change fixes the issue by sending ABORT command to the
firmware at the time when driver receives FLUSH command. Then
firmware will release all buffers, clean up session and send
ABORT_DONE back to the driver.

msm: mdss: hdmi: Security check for EDID 3D data parsing

While parsing EDID (Extended display identification data) received

to avoid data overflow or overwrite.
Also, replace snprintf with scnprintf for better memory copy results.

sched,cgroup: Fix up task_groups list

With multiple instances of task_groups, for_each_rt_rq() is a noop,
no task groups having been added to the rt.c list instance.  This
renders __enable/disable_runtime() and print_rt_stats() noop, the
user (non) visible effect being that rt task groups are missing in
/proc/sched_debug.

mm: fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate number of
dirtyable pages/pages that can be allocated to the page cache.  A bug
causes an underflow thus making the page count look like a big unsigned
number.  This in turn confuses the dirty writeback throttling to
aggressively write back pages as they become dirty (usually 1 page at a
time).  This generally only affects systems with highmem because the
underflowed count gets subtracted from the global count of dirtyable
memory.

The problem was introduced with v3.2-4896-gab8fabd

Fix is to ensure we don't get an underflowed total of either highmem or
global dirtyable memory.

msm: kgsl: avoid zero length scatterlist allocation

During sglist allocation we calculate sglen as
per below

sglen_alloc = PAGE_ALIGN(size) >> PAGE_SHIFT;

sglen_alloc can be zero if size falls within the
last page. For example, when size = 0xFFFF_FF7B,
PAGE_ALIGN(0xFFFF_FF7B) will be 0, considering
0x1000 (4kb) PAGE_SIZE. if kzalloc() with
zero size, it will return ZERO_SIZE_PTR which is
not NULL and we always do NULL check. Dereferencing
ZERO_SIZE_PTR will lead to a distinct access fault.
