3.2.82-rt119-rc1 stable review patch. If anyone has any objections, please let me know.
------------------ From: Sebastian Andrzej Siewior <bige...@linutronix.de> It has been pointed out by tglx that on UP the non-RT task could spin its entire time slice because the lock owner is preempted. This won't happen on !RT. So we back to "chill" if we can't cond_resched() did not work.
