The last two hunks will cause the same !CONFIG_KVM breakages qemu-kvm's
mpstate used to as well. You may either fix it up temporarily or wait
for my refactoring that is now scheduled with highest priority (should
be ready today or tomorrow).

It needs to go in 0.12-stable, so we'll have to leave with it.
Feel free to revert from master when refactoring.
Gleb/Glauber can you review please.

One additional patch is required to account for the new event flags,
also for upstream. Will post it in a minute.

Such hunks were better off in qemu-kvm.h, but this one is not the first
here.
