Right, so should we drop the "if (running)" check in this patch, at the same time as it's adding the IN_GUEST_MODE check?LOL, I think we have a Three^WTwo Stooges routine going on. This patch does remove avic_vcpu_is_running() and replaces it with the vcpu->mode check. Or am I completely misunderstanding what your referring to? - if (avic_vcpu_is_running(vcpu)) { + /* + * Signal the doorbell to tell hardware to inject the IRQ if the vCPU + * is in the guest.

Nevermind, I confused svm_deliver_avic_intr with avic_kick_target_vcpus, which anyway you are handling in patch 36.
