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,
