Hey Alex, sorry for the long delay. This patch is synchronized with the
QEMU series by registering an event notifier handler to process AP
configuration

change events. This is done by queuing the event and generating a CRW.
The series status is currently going through a v2 RFC after implementing
changes

requested by Cedric and Tony.

Let me know if there's anything else you're concerned with

Thanks!
