Well, the patch that got posted:

  [PATCH] tracing, perf: add more power related events

Only adds tracepoints to power.h, but doesnt actually use them anywhere 
...

Is there a companion patch i missed?

Also, it would be nice to add it to x86 and to OMAP at once, and 
synchronize up all the power events - and check how existing tools like 
powertop make use of such events - and sync it all up. We dont want to 
have inconsistent, architecture-dependent events in the end, for obvious 
reasons.

Thanks,

	Ingo
