Ho hum. The perfctr syscall API has changed so many times that whenever
someone adds a syscall I have rejects to fix up in probably ten different

It would be nice to start folding these patches together a bit to reduce
such problems, but that's rather non-trivial because there is no way to
simply join these patches together which maintains a sensible sequencing.

If we're going to do anything then it's either a major refactoring, or
simply wham the entire feature into a single diff. That diff could then be
split into four patches: core, ppc, x86 and x86_64. We would lose the
layering between ye olde perfctr, the inheritance implementation, the syfs
API, etc. I could live with that.
