For those that didn't read it, some food for thought:
http://lists.gnu.org/archive/html/qemu-devel/2013-01/msg01219.html

The basic assumptions that I have been operating under so far:
1) CPU hotplug will be x86-specific
2) The CPU is sufficiently different from a device to not use device_add
3) x86 CPU hotplug will not allow mixing different CPU types (Alex)

Previous art seems to be HMP cpu_set. Using any such specific operation
would allow us to abstract the ongoing QOM rework - I am about 2-3
series ahead of what has been posted but not there at QOM'ish hotplug
yet, so am open to any suggestions on the call.

Regards,
Andreas
