3.10.103-rt115-rc1 stable review patch.
If anyone has any objections, please let me know.

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

From: Sebastian Andrzej Siewior <bigeasy@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.
