4.1.33-rt38-rc1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <bige...@linutronix.de>

There should be no need to hold the base lock during the wakeup. There
should be no boosting involved, the wakeup list has its own lock so it
should be safe to do this without the lock.
