Here is a series of patches from Anton Blanchard that implement some
nice tracing and perf_event features on powerpc. One of them is
generic perf_event stuff (adding software events for alignment faults
and instruction emulation faults).
Since this touches the perf_event and tracing subsystems as well as the
powerpc architecture code, I think the best way forward is for both
Ingo and Ben to pull it into their trees. I have based it on the most
recent point in Linus' tree that Ingo had pulled into his perf
branches (as of yesterday or so).
Thanks,
Paul.
