These idles were necessary when the context switch code
preserved PM_OVERRIDE registers. That was removed some time
ago so now the idles are not needed.

Add support for snapshotting the state of the GPU in a binary format. The
snapshot can be pulled from sysfs and parsed off-target. The advantage is
that far more information can be encapsulated in a snapshot then can be
printed on the console during a hang. Snapshots are automatically created
during a hang, or can be manually triggered by writing 'trigger'
in /sys/class/kgsl/kgsl-<n>/snapshot where n is either the 2D or 3D device.
Snapshot data can be pulled from 'dump' in the same directory.

kmalloc allocates physically contiguous memory and
may fail for larger allocations due to fragmentation.
The large allocations are caused by the fact that the
scatterlist structure is 24 bytes and the array size
is proportional to the number of pages being mapped.

* changes:
msm: kgsl: only poke once during adreno_idle
msm: kgsl: Modify only the pending idle timer in ISR.
msm: kgsl: flush device workqueue before stop
The RBBM_STATUS loop is extremely tight and calling
adreno_poke() each time through this loop appears
to cause watchdog bites on 8960.

mod_timer reactivates the timer even when timer is deleted using
del_timer_sync. In the ISR we should be modifying only the pending
timer. We deleted the timer using del_timer_sync, if the interrupts
are still enabled, we could be re-enabling the timer in the ISR.
There is a code path in kgsl_suspend device where we delete the timer
but disable IRQ later.This code path seems to be fixed with another
commit.

Make sure the irq is off, the idle timer is
stopped and the workqueue is flushed before
stopping the device for early suspend, suspend,
last release or hang recovery. There is one case
where the workqueue cannot be flushed, which is from
kgsl_pwrctrl_sleep() when going into SLUMBER
state. This codepath can be called from the
workqueue itself so flushing would deadlock.

Establish a standard generic format for a GPU ID in the KGSL core:
[0:15] - GPU specific identifier
[16:31] - 0x0002 for 2D or 0x0003 for 3D
Add a KGSL core function to get the GPU ID from the devices and
GPU specific functions to return them. For Z180, the ID will be
0x0002000B4 (0xB4 = 180). For 3D, the ID will be 0x00030000 ORed
with the GPU identifier (anywhere from 205 to 225).
