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.

This is -next material right ?

Yes, please pull it into your next branch.
Thanks,
Paul.

The generic perf bits look good to me - can pull it if Ben OKs the
PowerPC bits.
Thanks,
Ingo

Yup. Just went through all of them, they look fine. I also test built on
a number of default configs and it seems to pass.
Cheers,
Ben.

Pulled into tip:perf/powerpc (will keep it in a separate branch for a
few days then it can go into perf/core), thanks guys!
