The best solution would be to drop > all those patches from Mark's tree. Read, not revert, drop. There have never been any users of the poweroff-source. The act8846 in the radxarock would have been the first, but I held off with the dts patch as the naming issue came up at the same time. So I guess if Romain keeps the renaming together there shouldn't be any other bad bisection points?
