Hi all-

Patch 1 is a regression fix and should go to linus and -stable.  (Not
necessarily x86/pti.  It's needed in 4.14, but if anyone backports
real PTI earlier than 4.14, this patch will *not* be needed.  The
regression doesn't really have anything to do with PTI.)

Patch 2 should probably go to normal -tip or even just wait for
Konstantin's ack.
