This sort of thing should work at some point:
probe perf.type(2).config(NN)
where NN comes from /debugfs/tracing/events/*/*/id
We could supply a shell script to parse the latter directory to come up with
a tapset correct for the currently running kernel. Or the translator could
do it, and store it cached based on kernel build-id or somesuch.
