When WLAN driver calls unregister driver, an event is posted to
event work queue and the calling thread waits for the event to
complete. In some cases like during suspend, calling thread gets
interrupted and wait_for_completion returns. Once it is returned,
WLAN module resources are freed including code segments and work
queue gets into Synchronous Abort.
Fix the issue by making unregister uninterruptible to make sure
WLAN driver clean-up happens gracefully without interrupted by
user space.

The current (CFS) scheduler implementation does not allow "to boost"
tasks performance by running them at a higher OPP compared to the
minimum required to meet their workload demands.
To support tasks performance boosting the scheduler should provide a
"knob" which allows to tune how much the system is going to be optimised
for energy efficiency vs performance.
This patch is the first of a series which provides a simple interface to
define a tuning knob. One system-wide "boost" tunable is exposed via:
/proc/sys/kernel/sched_cfs_boost
which can be configured in the range [0..100], to define a percentage
where:
- 0% boost requires to operate in "standard" mode by scheduling
tasks at the minimum capacities required by the workload demand
- 100% boost requires to push at maximum the task performances,
"regardless" of the incurred energy consumption
A boost value in between these two boundaries is used to bias the
power/performance trade-off, the higher the boost value the more the
scheduler is biased toward performance boosting instead of energy
efficiency.

The CPU controller hasn't kept up with the various changes in the whole
cgroup initialization / destruction sequence, and commit:
2e91fa7f6d ("cgroup: keep zombies associated with their original cgroups")
caused it to explode.
The reason for this is that zombies do not inhibit css_offline() from
being called, but do stall css_released(). Now we tear down the cfs_rq
structures on css_offline() but zombies can run after that, leading to
use-after-free issues.
The solution is to move the tear-down to css_released(), which
guarantees nobody (including no zombies) is still using our cgroup.
Furthermore, a few simple cleanups are possible too. There doesn't
appear to be any point to us using css_online() (anymore?) so fold that
in css_alloc().
And since cgroup code guarantees an RCU grace period between
css_released() and css_free() we can forgo using call_rcu() and free the
stuff immediately.

When a cgroup's CPU runqueue is destroyed, it should remove its
remaining load accounting from its parent cgroup.
The current site for doing so it unsuited because its far too late and
unordered against other cgroup removal (->css_free() will be, but we're also
in an RCU callback).
Put it in the ->css_offline() callback, which is the start of cgroup
destruction, right after the group has been made unavailable to
userspace. The ->css_offline() callbacks are called in hierarchical order
after the following v4.4 commit:
aa226ff4a1ce ("cgroup: make sure a parent css isn't offlined before its children")

CC_OUT is the signal/status to the PD that indicates which of
the CC line is active. When its low CC1 is active and when
high CC2 is active.
During Source -> Sink Power Role Swap, CC_OUT is reset default
low (CC1 = CC) when SW sets the UFP/SNK_EN_CMD bit, losing the
plug orientation info and causing USB PD message error if CC2
was the CC pin.
Fix this by ensuring that s/w overrides the CC_OUT signal to
reflect the actual one, in preparation for a possible upcoming
