kgsl: Implement conservative scaling policy

This behaves similarly to the conservative cpufreq governor,
which is similar to how most Mali GPU scaling algorithms behave.

The "trustzone" policy that is default relies on an undocumented
black box to make scaling decisions.

How to enable:
echo conservative > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy

Conservative attr group:
/sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative

Polling interval (10-1000):
/sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative/polling_interval

Enable stats printing (causes microlags on low polling intervals):
echo 1 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/policy_config/conservative/print_stats

NOTE:
- perms are set to 666 for testing purposes

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.

Issue: When a session is opened for playback of the touch tone and

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

msm: kgsl: Hold driver process mutex till sysfs entries deleted

sysfs entries deletion logic is not under the driver
process mutex lock, there was a Camera test case
where a single process was trying to call
kgsl_open/kgsl_release very rapidly from multiple
thread, sometimes sysfs entries remained valid
and kgsl_open was trying to create new sysfs
entries for same process id. This caused
WARNING in kernel logs "sysfs: cannot create
duplicate filename '/devices/virtual/kgsl/kgsl/proc/277'"
This change holds the driver process mutex
lock till sysfs entries are deleted.

msm: kgsl: Remove drawctxt_active from setstate default

drawctxt_active is cleared after the old context is removed
during context switch.  Unfortunately, the context restore calls
adreno_use_default_setstate() which always returns true if
drawctxt_active is NULL, effectively always forcing us down the
software path.

Remove the check - adreno_use_default_setstate() already checks to see
if the GPU is idle and that is a more reliable verification that the
software path is worth going down.
