This series introduces a new workqueue for handling hotplug events. On
PowerKVM guests, this provides a work deferral mechanism to avoid
processing hotplug events in interrupt context. On PowerVM lpars, this
will be used to ensure that hotplug events initiated from the HMC and
from PRRN events are handled and serialized properly.
