3.2.53-rt76-rc1 stable review patch. If anyone has any objections, please let me know.
------------------ From: Sebastian Andrzej Siewior <bige...@linutronix.de> The wait-simple queue is lighter weight and more efficient than the full wait queue, and may be used in atomic context on PREEMPT_RT. Fix up some places that needed to call the swait_*() functions instead of the wait_*() functions.
