Yes. For pseries, my patchset did CPU hotplug via device_add and
device_del commands. And that's what I am planning to stick to
going forward.

Yes, the last version I posted is at
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00650.html

Andreas mentioned that he would like to see some generic changes for
supporting device_add for CPU, socket vs core level hotplug, defining the
semantics etc. There was some discussion towards that and this is last I
heard about it:
