sched_avg: add run queue averaging.

Add code to calculate the run queue depth of a cpu and iowait
depth of the cpu.

The scheduler calls in to sched_update_nr_prod whenever there
is a runqueue change. This function maintains the runqueue average
and the iowait of that cpu in that time interval.

Whoever wants to know the runqueue average is expected to call
sched_get_nr_running_avg periodically to get the accumulated
runqueue and iowait averages for all the cpus.

sched: add PF_WAKE_UP_IDLE.

Certain workloads may benefit from the SD_SHARE_PKG_RESOURCES behavior
of waking their tasks up on idle CPUs. The feature has too much of a
negative impact on other workloads however to apply globally. The
PF_WAKE_UP_IDLE flag tells the scheduler to wake up tasks that have this
flag set, or tasks woken by tasks with this flag set, on an idle CPU
if one is available.

sched: add sysctl for controlling task migrations on wake

The PF_WAKE_UP_IDLE per-task flag made it impossible to enable
the old behavior of SD_SHARE_PKG_RESOURCES, where every task
migrates to an idle CPU on wakeup.

The sched_wake_to_idle sysctl value, when made nonzero, will cause
all tasks to migrate to an idle CPU if one is available when the
task is woken up. This is regardless of how PF_WAKE_UP_IDLE is
configured for tasks in the system. Similar to PF_WAKE_UP_IDLE,
the SD_SHARE_PKG_RESOURCES scheduler domain flag must be enabled
for the sysctl value to have an effect.

msm: kgsl: Synchronize access to IOMMU cfg port

Add a software based spinlock between CPU and GPU.
This spinlock is used to grant mutually exclusive access to
SMMU configuration between CPU and GPU. This mutual exclusion
is required to prevent deadlock in the system.

msm: dcvs: add ss_no_corr_below_freq parameter

The busy/idle behavior of different cores can be correlated by
DCVS when determining what frequency to run cores at. However,
this is not desirable below a certain frequency. Add a parameter
to establish what this frequency is. The parameter is configurable
in userspace via sysfs.

The ss_iobusy_conv parameter is currently unused, so it is
being replaced with ss_no_corr_below_freq.
