The fix it now would simply be to apply Ira original patch now, but
given that we are at -rc6 is this really a good time?  And if we don't
apply it now based on the quilt based -mm worflow it just seems a lot
easier to apply it after my series.  Unless we want to include it in
the series, in which case I can do a quick rebase, we'd just need to
make sure Andrew pulls it from -mm.
