In the current inject_page_fault path KVM only checks if there is another PF pending and injects a DF then. But it has to check for a pending DF too to detect a shutdown condition in the VCPU. If this is not detected the VCPU goes to a PF -> DF -> PF loop when it should triple fault. This patch detects this condition and handles it with an KVM_SHUTDOWN exit to userspace.
