Hi,

Here's an updated version of the patch. It should fix the problems
Hollis ran into, and also compile on x86_64 again :-)

I managed to get rid of all the runtime use of qemu_kvm_cpu_env(),
except for the hotplug code. But I think it's reasonable to do the
walk of the linked list in that case. However, the more I have looked
at this, the more obvious to me it becomes that it is right<tm> to
expose struct CPUState to libkvm, and avoid passing around int vcpu.

Comments and test reports very welcome!

Cheers,
Jes
