Subject: [Qemu-ppc] [PATCH v2 14/14] spapr_pci: emit hotplug add/remove events during hotplug

From: Tyrel Datwyler <address@hidden>

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

Userspace tools that don't implement this extension will need
to be run manually in response/advance of device_add/device_del,
