ASoC: msm: qdsp6: Fix pop noise seen with touch tone during playback

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: Get an active count before snapshotting GPU

Acquire an active count before attempting to capture a snapshot.
Doing so prevents instances of not being able to snapshot because of
switched off clocks.

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.

mm/page_alloc.c: fix watermark check in __zone_watermark_ok()

The watermark check consists of two sub-checks.  The first one is:

	if (free_pages <= min + lowmem_reserve)
		return false;

The check assures that there is minimal amount of RAM in the zone.  If
CMA is used then the free_pages is reduced by the number of free pages
in CMA prior to the over-mentioned check.

	if (!(alloc_flags & ALLOC_CMA))
		free_pages -= zone_page_state(z, NR_FREE_CMA_PAGES);

This prevents the zone from being drained from pages available for
non-movable allocations.

The second check prevents the zone from getting too fragmented.

	for (o = 0; o < order; o++) {
		free_pages -= z->free_area[o].nr_free << o;
		min >>= 1;
		if (free_pages <= min)
			return false;
	}

The field z->free_area[o].nr_free is equal to the number of free pages
including free CMA pages.  Therefore the CMA pages are subtracted twice.
This may cause a false positive fail of __zone_watermark_ok() if the CMA
area gets strongly fragmented.  In such a case there are many 0-order
free pages located in CMA.  Those pages are subtracted twice therefore
they will quickly drain free_pages during the check against
fragmentation.  The test fails even though there are many free non-cma
pages in the zone.

This patch fixes this issue by subtracting CMA pages only for a purpose of
(free_pages <= min + lowmem_reserve) check.

Laura said:

  We were observing allocation failures of higher order pages (order 5 =
  128K typically) under tight memory conditions resulting in driver
  failure.  The output from the page allocation failure showed plenty of
  free pages of the appropriate order/type/zone and mostly CMA pages in
  the lower orders.

  For full disclosure, we still observed some page allocation failures
  even after applying the patch but the number was drastically reduced and
  those failures were attributed to fragmentation/other system issues.
