Precedence: bulk

This contains two fixes for the "automatic demotion" code which was
merged into 5.15:

 * Fix memory hotplug performance regresssion by watching
   suppressing any real action on irrelevant hotplug events.
 * Ensure CPU hotplug handler is registered when memory hotplug
   is disabled.
