3.13.11-ckt18 -stable review patch. If anyone has any objections, please let
me know.
------------------
From: James Hogan <james.ho...@imgtec.com>
commit 044f0f03eca0110e1835b2ea038a484b93950328 upstream.
When about to run the guest, deliver guest interrupts after disabling
host interrupts. This should prevent an hrtimer interrupt from being
handled after delivering guest interrupts, and therefore not delivering
the guest timer interrupt until after the next guest exit.
