It's pretty clear that if we're going to take the hypervisor + dynamic reconfiguration thing seriously, we need a structured notion of adding and removing CPUs from the active CPU pool, including things like event handlers so that subsystems can shut down operations on the CPU. For example, UMA needs a chance to drain per-CPU caches of various zones, services that have pinned threads on the CPU will need to decide how to deal with that, etc. It's work I'd very much like to see happen, and until it's done we basically need to make sure that CPUs either exist from boot and never cease existing, or don't exist at boot and are never used.
I can't agree more. The whole hlt_cpus_mask change leaves taste of the very bad hack.
