Looks really nice, thanks Masami!

Note, i've created a new topic tree for this work: tip:perf/probes, and
have put all the commits there - since i expect most of the
enabling/completion work for this feature to happen on the perf events
side.

I also merged this tree upto v2.6.32-rc5 and resolved a conflict with
recent tracing fixes. Please base future patches on this new tree.

Thanks,

Ingo
