misc: uidstat: avoid create_stat() race and blockage.

cpufreq: interactive: handle errors from cpufreq_frequency_table_target

Add checks for error return from cpufreq_frequency_table_target, and be
less noisy on the existing call with an error check.  CPU hotplug and
system shutdown may cause this call to return -EINVAL.

cpufreq: interactive: reduce chance of zero time delta on load eval

Reschedule load sampling timer after timestamp of sample start taken,
hold spinlock across entire sequence to avoid preemption.  Avoid the
WARN for zero time delta in the load sampling timer function.

block: Squashed update of BFQ-v6 to BFQ-v6r1

- Introduce an eqm_lock to protect EQM-related data.
- Fix use-after-free of queues in __bfq_bfqq_expire(). It may happen that
  a call to bfq_del_bfqq_busy() puts the last reference taken on a queue
  and frees it. Subsequent accesses to that same queue would result in a
  use-after-free. Make sure that a queue that has just been deleted from
  busy is no more touched.
- Use the uninitialized_var() macro when needed. It may happen that a
  variable is initialized in a function that is called by the function
  that defined it. Use the uninitialized_var() macro in these cases.
Squashed update of kernel from 3.0.81 to 3.0.82
Squashed update of BFQ-v6r1 to BFQ-v6r2
msm: kgsl: Always resume the GPU regardless of its state

Make sure we resume the GPU regardless of its current
state. If the device is not in suspend state restart the
device and  print an error message.

cpufreq: interactive: fix race on cpufreq TRANSITION notifier

The cpufreq TRANSTION notifier callback does not check the
governor_enabled state on affected CPUS, which will case
kernel panic in update_load because the policy object maybe
NULL or invalid when governor_enabled is false.

cpufreq: interactive: resched timer if max freq raised

When the policy max freq is raised, and before the timer is
rescheduled in idle callback, the cpu freq may stuck at a
lower freq.

The target_freq shall be updated too, else on a high load
situation, the new_freq is always equal to target_freq and
which will cause freq stuck at a lower freq too.

Reschedule the timer on gov limits callback.
