I am clearly missing some kernel patch to try out this perf patch. I have
the 4 timekeeper ones; none of those modify perf_event code. What other
patches are needed? Was this one (or some variant) accepted:

Jah, I now realize I forgot to post that one, I did post the
monotonic_raw nmi patches again, but forgot about this one.
Perhaps a better question is what tree has all of the kernel side patches?
tip/master should have it all.
