These are in comments though so I'm not sure the coding-style rules
apply. I can change it if if *really* annoys you though :)

Great, thanks! The hard part is going to be getting this merged
without breaking any pending patches to perf_event.c. I think we're
alright at the moment for 2.6.38 but if you see any patches getting
scheduled that touch the old code, please let me know.
