cfg80211: unblock user hint when cfg80211_regdom is intersected

If the driver is loaded when cfg80211_regdom is intersected then
user hint will fail for the first time since cfg80211 does not
have a check to see if cfg80211_regdom is intersected. Add
a check to see if cf80211_regdom is intersected and allow the
user hint to be processed.

ARM: Don't dump vmalloc addresses with show_data()

Memory-mapped IO address spaces cannot be safely dumped at will.
Some addresses may not be available (clocked, powered) at all times,
and may result in hangs or bus decode errors if accessed. Other
registers that are accessible may have read side-effects, and dumping
them may have adverse affects on stability or the functionality of
the affected peripheral.

Be safe, and skip dumping such addresses altogether.

prctl: adds PR_SET_TIMERSLACK_PID for setting timer slack of an arbitrary thread.

Second argument is similar to PR_SET_TIMERSLACK, if non-zero then the
slack is set to that value otherwise sets it to the default for the thread.

Takes PID of the thread as the third argument.

This allows power/performance management software to set timer slack for
other threads according to its policy for the thread (such as when the
thread is designated foreground vs. background activity)

nf: IDLETIMER: time-stamp and suspend/resume handling.

Message notifications contains an additional timestamp field in nano seconds.
The expiry time for the timers are modified during suspend/resume.
If timer was supposed to expire while the system is suspended then a
notification is sent when it resumes with the timestamp of the scheduled expiry.

Removes the race condition for multiple work scheduled.

In the callback function src_port was being used
instead of dest_port for returning the callbacks.
Fixed by changing src_port to dest_port.

block: Switch from BFQ-v7r2 for 3.4.0 to BFQ-v7r3 for 3.4.0

. IMPROVEMENT: Improved throughput boosting with NCQ-capable HDDs and
  random workloads. The mechanism that further boosts throghput with
  these devices and workloads is activated only in the cases where it
  does not cause any violation of throughput-distribution and latency
  guarantees.
. IMPROVEMENT: Generalized the computation of the parameters of the
  low-latency heuristic for interactive applications, so as to fit also
  slower storage devices. The purpose of this improvement is to preserve
  low-latency guarantees for interactive applications also on slower
  devices, such as portable hard disks, multimedia and SD cards.
. BUGFIX: Re-added MODULE_LICENSE macro.
. CODE IMPROVEMENTS: Small code cleanups; introduced a coherent naming
  scheme for all identifiers related to weight raising; refactored and
  optimized a few hot paths.
