Gleb, Paolo,
since the qemu part relies on a kernel header file, it makes sense to not only let the kernel
part go via the kvm tree, but also the qemu part. I want Alex to Ack the interface, and if he
agrees then I am fine with applying the whole series.
If nothing else comes up, feel free to apply the small change request from Peter yourself or
ask Jens for a resend.
