Generally speaking, hypervisor can't know if the CPU is offline (or e.g. 'isolated') from guest's perspective so I think having an option to specify affinity for reenlightenment notification is rather a good thing, not bad. (Actually, I don't remember if I tried specifying 'HV_ANY' (U32_MAX-1) here to see what happens. But then I doubt it'll notice the fact that we offlined some CPU so we may get a totally unexpected IRQ there). -- Vitaly
