Since the series needs a resend anyway folding back ought to be fine i think. I'm wondering whether this should get into tip:perf/urgent - or in tip:perf/core for 2.6.35. It fixes sw event call trace ugliness, but is that a 2.6.34 regression? Is there any other aspect of the series that points towards accelerating this into .34? Thanks, Ingo
