ASoC: msm: qdsp6: Fixed the issue unmap command is sent incorrectly

When session CLOSE command is sent right before session RUN command
is acknowledged, callback function can mistakenly think that
the next received acknowledgement is for CLOSE command instead of
RUN command. This triggers driver to send memory unmap command to
the Q6 while it is still processing the CLOSE command. Eventually,
this leads to an invalid memory access and causes Q6 crash.

ASoC: msm: qdsp6: Fixed the volume command timeout issue

QDSP6 can send out of sequence response and this breaks
the no wait command tracking logic. It results the wait
command response gets ignored and causes the wait time out.
To resolve the issue, each response needs to be checked
to determine if the response is for no wait or wait command.

ASoC: msm: Fix for a seekbar issue during audio playback.

Issue is that when seek happens several times during audio playback,
and at some point last buffer write done event from DSP is received,
an ioctl drain is issued, which will set pending_buffer flag to 0,
In the mean time before drain finishes a seek comes, which issues
a flush on all the buffers and try to resume the playback again.
Now because the pending_buffer flag is set to 0, CMD_RUN will return
without any further writes to DSP. As a result no audio buffers are
reaching the DSP and hence no audio is getting played.
Make a fix is to set pending_buffer flag to 1 whenever playback is resumed
after seek.

cpufreq: interactive: add timer slack to limit idle at speed > min

Always use deferrable timer for load sampling.

Set a non-deferrable timer to an additional slack time to allow prior to
waking up from idle to drop speed when not at minimum speed.  Slack value
-1 avoids wakeups to drop speed.  Default is 80ms.

Remove the governidle module param and its timer management in idle.  For
platforms on which holding speed above mimum in idle costs power, use the
new timer slack to select how long to wait before waking up to drop speed.

cpufreq: interactive: fix racy timer stopping

When stopping the governor, del_timer_sync() can race against an
invocation of the idle notifier callback, which has the potential
to reactivate the timer.

To fix this issue, a read-write semaphore is used. Multiple readers are
allowed as long as pcpu->governor_enabled is true.  However it can be
moved to false only after taking a write semaphore which would wait for
any on-going asynchronous activities to complete and prevent any more of
those activities to be initiated.

cpufreq: interactive: fix race on timer restart on governor start

Starting the governor, or restarting on a hotplugged-in CPU, can race
with the timer start in idle, triggering a BUG on timer already pending.
Start the timer before setting the enable flag, and use enable_sem to
protect the sequence (and ensure correct order of the update to the
enable flag).  Delete any existing timer for safety.

cpufreq: interactive: default go_hispeed_load 99%, doc updates

Update default go_hispeed_load from 85% to 99%.  Recent changes to the
governor now use a default target_load of 90%.  go_hispeed_load should
not be lower than the target load for hispeed_freq, which could lead
to oscillating speed decisions.  Other recent changes reduce the need
to dampen speed jumps on load spikes, while input event boosts from
userspace are the preferred method for anticipating load spikes with
UI impacts.

General update to the documentation to reflect recent changes.

msm: kgsl: Remove incorrect check for current context

We remove an incorrect check for currently active context.
The intent of the original check was to ensure that the
current context is at least there/valid before we issue
a dummy command with a forced interrupt. However, this
check was implemented incorrectly, instead of checking
the context under which the function is running, the check
was probing the "drawctxt_active" which may not necessarily
be the same as the context for which the function was called.
We fix this by changing the check to instead look for the
context under which the kgsl_check_interrupt_timestamp() has
been called.

msm: kgsl: Make the GPU device aware of the next pending event

The adreno core needs to know what the next event pending for
any given context is so it can mark the interupt to be fired.
If this isn't done then some timestamps that don't have a
matching waittimestamp call won't fire an interrupt. This is
dangerous on the last interrupt/event before a context goes
away.
