They're in kvmarm/next, which is a stable branch (doesn't rebase) so our
only choice would be to revert this commit specifically in kvmarm/next
before sending the pull request.  Since that would be more confusing
than help anything, and Paolo said to just include the duplicate commit
in the pull request, here it is.

As we can see in linux-next, it's not really a problem.
