From 044f0f03eca0110e1835b2ea038a484b93950328 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Thu, 29 May 2014 10:16:32 +0100 Subject: [PATCH] MIPS: KVM: Deliver guest interrupts after local_irq_disable() 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.
