From: James Hogan <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== 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.
