run_tests only runs the perf_event regressiong tests.

To run the fuzzer, enter the "fuzzer" directory and either run
which will run the fuzzer repeatedly, or you can instead just run
but that sometimes eventually errors out if it manages to get stuck in a
signal storm.

While running on haswell and skylake machines the WARNINGs trigger fairly
quickly (within minutes usually).

You might also encounter a handful of other known kernel warnings which
I've reported in the past and usually just ignore.
