From: Glauber Costa <glom...@redhat.com>
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.
