Missing: switch the uncached path to a work queue, so we don't have to iterate over all vcpus in interrupt context. That isn't trivial; for edge-triggered interrupts we need to ignore zeros (if polarity=0) but for level-triggered interrupts we need them to override the previous setting. But we don't know the trigger mode and polarity at this point. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
