sync: signal pt before sync_timeline object gets destroyed

There is a race condition

Assume we have *one* sync_fence object, with *one* sync_pt
which belongs to *one* sync_timeline, given this condition,
sync_timeline->kref will have two counts, one for sync_timeline
(implicit) and another for sync_pt.

Assume following is the situation on CPU

Theead-1 : (Thread which calls sync_timeline_destroy())
  -> (some function calls)
   -> sync_timeline_destory()
    -> sync_timeline_signal() (CPU is inside this
function after putting reference to sync_timeline)

At this time Thread-2 comes and does following

Thread-2 : (fclose on fence fd)
> sync_fence_release() -> because of fclose() on fence object
 -> sync_fence_free()
  -> sync_pt_free()
   -> kref_put(&pt->parent->kref, sync_timeline_free);
    -> sync_timeline_free() (CPU is inside this because
this time kref will be zero after _put)

Thread-2 will free sync_timeline object before Thread-1
has finished its work inside sync_timeline_signal.

With this change we signals all sync_pt before putting
reference to sync_timeline object.

msm: kgsl: always check ft and hw gates in kgsl_active_count_get

The device state can fluctuate during recovery and resume, so
it is safer to check the gates unconditionally rather than
trust the state. The gates are left open until recovery
or suspend starts.

msm: kgsl: Do not wait for FT gate in fault tolerance state

When device start fails, device is in INIT state and FT is triggered.
In FT we trigger snapshot which waits on ft_gate when active count is
0 and device is not in active state. This causes a deadlock. This
change does not wait for FT gate in FT state and thereby prevents
the deadlock.

ALSA: pcm: check for integer overflow during multiplication

Channel info data structure is parsed from userspace and if
user does not set the no. of channels correctly, it could lead
to security vulnerability if we don't check for overflow when the
no. of channels is multiplied with pcm bit width. Add a condition
to check for overflow during multiplication.

msm: kgsl: enable CPU IRQ while suspending context

Make sure that CPU interrupt is enabled before calling adreno
suspend_context when moving from NAP/SLEEP to SLUMBER state.
We send commands to GPU in adreno_drawctxt_switch() which will generate
GPU interrupt. Since CPU interrupt is not enabled, adreno_idle() will
fail because pending interrupt will not be served by CPU this causes
false GPU hang.

Issue: When a session is opened for playback of the touch tone and
	routed through the COPP, the PBE and IIR params are being
	reconfigured in the COPP every time a session is open.

Rootcause:Configuring the PBE/IIR in the COPP every time a session
           is open.
Fix: Configuring the PBE and IIR param in the COPP one time a session
      is open

msm: kgsl: Count user and kernel performance counters seperately

Rather than just storing if the performance counter was referenced by the
kernel in a flag, keep track of user space and kernel space references
seperately.  This allows finer grained manipulations on the performance
counters (ie when allowed to be released).  This is needed to be able to
turn off certain performance counters when fault tolerance is disabled
at runtime.
