I think you are misunderstanding here. Xen and QEMU suffer from a problem where they misemulate single events that cause two vectors (such as mapping LINT0 to NMI as linux sometimes does). My patch only prioritizes in the sense of ordering between the two sources...both vectors would actually get injected eventually. That is the difference. Xen/QEMU drop one of the vectors (with favor going to EXTINT), whereas mine honors both based on how the "hw" is programmed. So they are not the same.
