Subject: [PATCH 0/6] more perf_counter stuff

This patch set implements some features requested by Paul/Corey.
The main one being the singleshot thing, which is still RFC due to
being incomplete.

It really needs a mechanism to run bits in a regular context ASAP
after the event context. My faviourite is a self-IPI, because one can
issue it from NMI context, or IRQ-disabled rq->lock context and have
it work as expected.

I'll look at doing a x86 self-IPI.
