Slightly modified version of a patch already included in qemu-kvm: This is a patch actually written by Juan, which, according to him, he plans on posting to qemu.git. Problem is that linux defines u64 in a way that is type-uncompatible with uint64_t. I am including it here, because it is a dependency to my patch series that follows.
