IMHO, it might be easier when it goes via tip. Peter, feel free to take it. The patch does not create any conflict with the klp tree. But I guess that there might be some dependent patches in tip... That said, I could take it via the livepatch tree if Peter preferred it from some reasons. Anyway, the patch looks good and passes the tests.
