In addition I've renamed inject_pending_event to handle_processor_events. The series now passes kvm-unit-tests and various nested hypervisor tests so now it's *really* ready for review! (Thanks Krish for looking at it so far). I'm quite pleased with the overall look of the code, though the INT_CTL arbitration is a bit ugly. I have plans to implement nested vGIF and vLS, and then I will probably clean it up.
