were already present in the tree and fix cpu-hotplug.
One of the latest merges from the QEMU 1.6 stable tree effectively
reverted them. May I have a release exception to push them back in?
Without them cpu-hotplug does not work.

It looks like this touches vcpu initialization, which is pretty core to the functionality of a VM as a whole. Hotplug, on the other hand, while an important feature, is much less commonly used.

Given that we're hoping to have an RC5 tomorrow and tag a release next week, I think I'd rather these wait until 4.4.1.
