devfreq: governor_cpubw_hwmon: Fix use of decay_rate

The decay rate tunable is used to compute the current averaged bandwidth
use, but the calculated value is never used. Fix this by using the
calculated averaged bandwidth instead of the instantaneous measured
bandwidth when computing the AB and IB votes.

msm: msm_bus: Don't divide RPM BW requests

When sending bandwidth requests to slave don't divide the request by
the number of ports as this is done at the RPM driver.

msm: kgsl: Pass the right timeout to adreno_drawctxt_wait()

adreno_drawctxt_wait() expects the passed in timeout to be in
milliseconds and converts it to jiffies.  Unfortunately, so does
the caller so the timeout is shorter than it should be.

msm: kgsl: Add arch_mmap_check() stub definition

Add a stub definition for arch_mmap_check() in kgsl.c for
situations where the function is not defined, similar to the
stub definition in mm/mmap.c

msm: kgsl: protect syncpoint events with a reference count

Replace the event spinlock with krefs to avoid the possiblity
of calling a sleeping function while holding the spinlock and
to generally make the whole cmdbatch cancel loop a lot more
stable.

msm: kgsl: fix race condition setting the event->handle

A race condition existed for setting the event->handle since the
async event can signal at any time after it has been registered.
When the event signals the reference count for the synclist and
the async callback are decremented causing the event to be freed.
The kgsl_cmdbatch_add_sync_fence function needs to take another
reference to ensure that the handle can be set before the event
is freed.
