Using memory barriers does not guarantee that the writes will
be completed before moving further unless the memory is marked
as strongly ordered. Use a read instead to make sure that the
previous writes take effect before the read can be processed
and we continue further.

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.

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
