The discussion on the actual change seems to have pointed out all needs of change, but what I wasn't able to understand yet is why this is needed in the first place. From hypervisor pov, so far it's been up to the guest which CPUs get onlined/offlined, and the interface to request offlining (not an issue for onlining) was - afaict - a purely voluntary one. Why does this change with PVH? Any such ratonale should be put in the commit message.
