From: Tyrel Datwyler <tyr...@linux.vnet.ibm.com>
This uses extension of existing EPOW interrupt/event mechanism
to notify userspace tools like librtas/drmgr to handle
in-guest configuration/cleanup operations in response to
device_add/device_del.
Userspace tools that don't implement this extension will need
to be run manually in response/advance of device_add/device_del,
respectively.
