video: msm: Add multiplier to MDP bandwidth calculation

 * We have major underruns on 8660 without higher bandwidth. Scale it by
   2x to achieve a solid framerate with no underrun.

msm: htc_battery: Use fast (5 sec) timer while on battery power

Previously, the battery driver would refresh itself every 60 seconds, resulting in grossly inaccurate battery readings. Refresh battery driver every 5 seconds while on battery power, and silence resulting logspam.

msm: kgsl: Cleanup the memory free list

Tighten up the memory free list code and remove the memory unused
debugfs file.  Outside of the cleanup the functional changes are
a) move the mutex to a spinlock for speed, and b) only return the
last entry in the list for given pid/gpu address combination.

msm: kgsl: Fix GPUMMU mapping.

Change "msm: kgsl: allow consistent CPU and GPU mappings" broke the older,
GPUMMU mapping. Revert it partially to keep older targets working.

Not tested with IOMMU targets.
msm: kgsl: hold a process_private refcount in process_mem_print

There is a possible race condition where the process can be going
away while its debugfs 'mem' file is being read, which could cause
memory corruption.

msm: kgsl: Look up the process struct in process_mem_open()

The pointer to an active process struct stands the risk of going stale
if process_mem_open() is called just before the debugfs dentry is
destroyed.  Instead of storing and using the pointer pass the process pid
to process_mem_open() and do a lookup to ensure that we always get active
processes.

msm: kgsl: prevent kgsl_get_pagetable from returning a destroyed pt

A race condition exists between kref_get_pagetable and
kref_put_pagetable such that is is possible to put the last
reference to a pagetable slightly before it has been removed
from the list. By checking kref_get_unless_zero we can determine
if the last reference has already been released. This is safe
because the list is protected by a ptlock.

msm: kgsl: Fix spinlock recursion in destroy pagetable

pagetable list is protected by ptlock. Few functions
while iterating over a pagetable list takes same ptlock,
kgsl_destroy_pagetable() also need same lock. This will
cause spinlock recursion if kgsl_destroy_pagetable()
called while iterating over a list. Created two versions
of same function one is with lock and other is without
lock.

Avoid to create duplicate filename for misc devices.

There has two bugs.
1. For example, the 'psaux' device will use '1' as minor number to
register misc device, but misc deriver doesn't set the '1' as used.
It's the root casue for duplicate filename.
2. From warning message, minor number '1' is the one of duplicate
fileanme, it meanes the number of dynamic minor is not enough.

The symptom of creating duplicate filename:
