[ Upstream commit 2a9c45d8f89112458364285cbe2b0729561953f1 ]

Drop the Ultraviolet patch. UV looks broken upstream for PREEMPT, too.
Mike is the only person I know that has such a thing and he isn't going
to fix this upstream (from 1526977462.6491.1.camel@gmx.de):

I don't think that we need to propagate that revert for stable. I
reverted it in the devel tree because nobody wanted this upstream and I
couldn't test it. For that reason I didn't see the point for having it
in the RT tree.
However, if you want to revert it for stable, be my guest. It probably
will have no impact and if it will people might step forward and fix it
properly / upstream.

I'm in favor of reverting it as useless cruft.  UV has been broken
forever wrt PREEMPT, and nobody cares.  The original interest in UV RT
support evaporated while 2.6.33-rt was still current (and when getting
it working took a bit more than a spinlock conversion).
