ASoC: wcd9320: remove runtime PM voting

All the codec reads/writes go through slimbus satellite driver on APPS.
Slimbus satellite driver is already voting for slimbus clock before any
codec read or write so remove the vote from codec driver

cpufreq: Sync on thread migration optimizations

When threads migrate between CPUs the destination CPU will temporarily
have a boosted frequency and the source CPU will have a residual higher
frequency even though the load could have just been reduced. To avoid
leaving CPUs at a high frequencies notify the source CPU after a thread
migration and make the interactive governor's timer reschedule
conditionally.

cpufreq: cpu-boost: Re-issue boosts above minimum frequency

Frequency boosts where the source CPU frequency is greater than CPU's
minimum frequency should always go through regardless of the destination
CPU's current frequency. This fixes a performance issue where the governor
lowers the CPU frequency shortly after a thread is migrated to it because
the boost wasn't re-issued.

cpufreq: cpu-boost: Introduce scheduler assisted load based syncs

Previously, on getting a migration notification cpu-boost changed
the scaling min of the destination frequency to match that of the
source frequency or sync_threshold whichever was minimum.

If the scheduler migration notification is extended with task load
(cpu demand) information, the cpu boost driver can use this load to
compute a suitable frequency for the migrating task. The required
frequency for the task is calculated by taking the load percentage
of the max frequency and no sync is performed if the load is less
than a particular value (migration_load_threshold).This change is
beneficial for both perf and power as demand of a task is taken into
consideration while making cpufreq decisions and unnecessary syncs
for lightweight tasks are avoided.

The task load information provided by scheduler comes from a
window-based load collection mechanism which also normalizes the
load collected by the scheduler to the max possible frequency
across all CPUs.

cpufreq: cpu-boost: Handle wakeup hints received for foreground tasks

A previous change modifies the notification conditions in the scheduler
to call the notifier chain even on foreground_thread wakeups for tasks
having load more than a threshold value.

If load_based_syncs is turned OFF then we do not need to perform
cpu boost for wakeup hints for foreground tasks from scheduler

cpufreq: interactive: Don't reset sampling down factor at max freq

A previous patch sets the min_sample_time to zero if the cpufreq
min/max limits have changed which would bring down the frequency
in the next sample even if min_sample_time doesnt allow it to do so.
This could severly affect benchmarks if this is applied to max
frequencies as min_sample_time for max frequencies is set to
sampling_down_factor.
This patch resets the limits_changed flag for cases where timer fires
while running at max frequencies so that sampling_down_factor is
still applicable as before.

sched: Make scheduler aware of cpu frequency state

Capacity of a cpu (how much performance it can deliver) is partly
determined by its frequency (P) state, both current frequency as well
as max frequency it can reach.  Knowing frequency state of cpus will
help scheduler optimize various functions such as tracking every
task's cpu demand and placing tasks on various cpus.

This patch has scheduler registering for cpufreq notifications to
become aware of cpu's frequency state. Subsequent patches will make
use of derived information for various purposes, such as task's scaled
load (cpu demand) accounting and task placement.

sched: window-based load stats for tasks

Provide a metric per task that specifies how cpu bound a task is. Task
execution is monitored over several time windows and the fraction of
the window for which task was found to be executing or wanting to run
is recorded as task's demand. Windows over which task was sleeping are
ignored. We track last 5 recent windows for every task and the maximum
demand seen in any of the previous 5 windows (where task had some
activity) drives freq demand for every task.

A per-cpu metric (rq->cumulative_runnable_avg) is also provided which
is an aggregation of cpu demand of all tasks currently enqueued on it.
rq->cumulative_runnable_avg will be useful to know if cpu frequency
will need to be changed to match task demand.

sched: Call the notify_on_migrate notifier chain for wakeups as well

Add a change to send notify_on_migrate hints on wakeups of
foreground tasks from scheduler if their load is above
wakeup_load_thresholds (default value is 60).
These hints can be used to choose an appropriate CPU frequency
corresponding to the load of the task being woken up.

genalloc: Correct nbytes calculation on long boundary

In existing code we calculate nbytes based on the byte
boundary, but genalloc uses bitmap for maintaining the
memory allocation aligned to long. So while calculating
nbytes we end up getting wrong nbytes.
example: lets say nbytes comes to 9 bytes for 70 bits when
bytes aligned,but if long aligned we will have 3 long words
i.e 12 bytes. This difference may lead to choosing the
wrong api for freeing the memory i.e Between kfree() and
vfree().
Fix was inspired by an upstream commit
eedce141cd2dad8d0cefc5468ef41898949a7031, bringing same fix
into the gen_pool_detroy path.
