IPAv2 hardware works with 32 bit addressing,
so allocate a kernel memory using GFP_DMA flag
which is processed by IPA hardware. Added code
changes to free correct tx_pkt pointer in fail_dma_map condition.

Caller of tz_handler() is having the NULL check for devfreq,So
we don’t need unnecessary NULL pointer check.

Race is happening when both audio_pcm_close() and audio_send()
executes in parallel.
When the PCM session is closed, the substream attribute of the
audio_dev structure is set to NULL in audio_pcm_close().
As there is no synchronization protection for the audio_dev subtream
attributes in audio_send(), it is causing NULL pointer dereference.
Hence fixing the issue by adding proper synchronization protection
for the audio_dev subtream attributes in audio_send().

Reduce the latency of device switch during voice call by caching
IIR Band registers at bootup and restore them in
tavil_dig_core_remove_power_collapse instead of updating
through mixer controls from userspace.

For any cache operation, the current code tries to map all pages to the
kernel using vmap in case sg table is not available and then performs
the requested cache operation. If vmap fails because of memory crunch
ioctl just returns failure.
This change avoids using vmap and performs per page cache operation
even when sg table is not available. This is done to avoid failures
because of vmap especially on 32 bit systems.

Currently perf_event.c is 64bit specific due to
inline assembly. Driver needs to support 32bit as well.
Move the assembly code to asm/perf_event.h so that
perf_event.c is 32/64 bit agnostic and move perf_event.c
to drivers/perf from 64bit-specific arch dir.
