But they are all related and the code becomes uglier if you only prefix
one of them.  If you don't convert all of them, I will do it anyway as
soon as this patch get in.

Since it touches a lot of KVM files, we should synchronize in order to
avoid conflicts and gnashing of teeth.  What tree is this patch going
in?  You could provide me a commit SHA1 for this patch (well, its
definitive version) based on Linus's tree (so that I can merge it in my
tree as well), or I could commit it and provide the SHA1 to the
maintainer of said tree.
