cpuboost: Add hotplug boosting

If we decide to hotplug a core then we are making a strong
statement that we think that the system load is high.  Let's
have faith in our hotplug driver(s) and boost the cpufreq
when we are hotplugging cores.

[myfluxi: shorter boost, minor style changes]

mmc: core: continue to wait, when unblocked by signal

Mmc thread is waiting for one of following events occurs:
- current running request completion (is_done_rcv)
- new request notification arrived (is_new_req)
- urgent request notification arrived (is_urgent)
or the thread received a signal. In this case none of described events
happened.

This change process the case, when mmc thread was unblocked from wait by
signal, for example system shutdown flow.

unix: fix a race condition in unix_release()

As reported by Jan, and others over the past few years, there is a
race condition caused by unix_release setting the sock->sk pointer
to NULL before properly marking the socket as dead/orphaned.  This
can cause a problem with the LSM hook security_unix_may_send() if
there is another socket attempting to write to this partially
released socket in between when sock->sk is set to NULL and it is
marked as dead/orphaned.  This patch fixes this by only setting
sock->sk to NULL after the socket has been marked as dead; I also
take the opportunity to make unix_release_sock() a void function
as it only ever returned 0/success.

Dave, I think this one should go on the -stable pile.

Special thanks to Jan for coming up with a reproducer for this
problem.
