The duplication looks pretty limited to me, so I don't think it's a problem. How well tested is this on real hardware and how robust is the hardware with this? Since it's a new PMU driver for v3.7, and if these are reasonably well tested, then we could send these to Linus via perf/urgent, so that they don't miss and have to wait all the way to v3.8.
