Asoc: msm: 8064: Set channel as Mono for Incall Music Delivery

For incall music delivery, there is only one share channel is
supported between MDM and APQ. If the media is stereo, afe tries to
open two share channels and causes music playback failure.
Add fixup fucntion to always set the channel as 1 whenever the media
is stereo or mono. And make sure only one share channel is opened.

ASoC: msm: Reduce min buffer size for low latency

The current low latency driver has 512 bytes as
the min buffer size threshold. With this reducing
the playback time to lower values is not possible.
Setting it to 128 bytes gives us more room
to try out lower buffer sizes from the user space

ASoC: msm: Change QOS value for low latency path

There were variations in the time taken to

to the delay in switching in and out of

time to wake up from power collapse

ASoC: msm: Flexible period size for pcm playback

PCM driver was configured for fixed buffer
size on the playback path. With this, varying
the buffer sizes on the playback path was not
possible. To fix this, support for flexible
period sizes is added by setting different
values for min and max buffer sizes

msm: kgsl: Use the kmalloc/vmalloc trick for the sharedmem page array

It was previously assumed that most GPU memory allocations would be
small enough to allow us to fit the array of page pointers into one
or two pages allocated via kmalloc.  Recent reports have proven
those assumptions to be wrong - allocations on the order of 32MB will
end up trying to get 8 pages from kmalloc and 8 contiguous pages
on a busy system are a rare beast indeed.

So use the usual kmalloc/vmalloc trick instead - use kmalloc for the
page array when we can and vmalloc if we can't.

msm: kgsl: send ringbuffer NOP padding with the next command

If there isn't enough room at the bottom of the ringbuffer for a
whole command, the remaining space is filled with NOPs and
the command starts again at the top of the ringbuffer, the write
pointer of the ringbuffer shall update accordingly; the existing
implementation sends out in-complete NOP command which may potentially
cause GPU hang. This fix submits the NOP command along with the next
command instead of submitting them separately to have GPU read both
commands in the same fetch.

Add a check to free the kgsl_timeline object only after

from kgsl if it is already freed and also to catch any unbalanced
kref count.

ARM: 7693/1: mm: clean-up in order to reduce to call kmap_high_get()

In kmap_atomic(), kmap_high_get() is invoked for checking already
mapped area. In __flush_dcache_page() and dma_cache_maint_page(),
we explicitly call kmap_high_get() before kmap_atomic()
when cache_is_vipt(), so kmap_high_get() can be invoked twice.
This is useless operation, so remove one.

v2: change cache_is_vipt() to cache_is_vipt_nonaliasing() in order to
be self-documented
