Just to be consistent with other flush API. Hmm. Do you really want a CPU being brought up to do that to the PoU, every time that it is brought up? I thought you wanted to get rid of that kind of stuff from the hotplug paths so that a CPU being brought up/taken down doesn't affect the caches for the other CPUs within the inner sharable domain.
