I just noticed that it's been pulled into
http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=commitdiff;h=69c358ce377e998e3ababb494c2f8769dfb1715d
and mentioned in
http://lists.xensource.com/archives/html/xen-devel/2011-03/msg00718.html
So I'm sending it to the list (with adjusted Subject and In-Reply-To)
just in case.
