It'll look a little different because I'm expect to adjust it slightly to match Andrew's tree but there should be no major surprises and my expectation is that testing a -rc kernel after it gets merged is all that is necessary. I'm planning to backport this to -stable but it'll remain to be seen if I can convince the relevant maintainers that it should be merged.
