probably. That was a last minute addition. I have a much more complete
set of tests writted for PAPI and I'm trying to port over the ones that
make sense to be perf-event direct. Properly programming perf_event
generalized cache events isn't documented very well though.
I've been distracted by the fact that my overflow tests start failing as
of kernel 2.6.36 :( I hadn't noticed because I was primarily developing
the tests on 2.6.32 and 2.6.35 machines.
