I stuck this and some of the other in this thread on 'stable/bug-fixes-rc3'
(git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git). But before
I send them to Linus to pull I need your OK? Would it be OK if I stuck
your Ack on the patch?

Or you could take this patch (the one I stuck in my tree has the description
a bit modified so I recommend that one).
