Perfmon adds a ridiculous number of syscalls, which means we *really*
shouldn't merge it until they're reserved upstream, otherwise backwards
compat woes will ensue. However, perfmon doesn't look like it is
anywhere near being merged in the current form, so I'd rate it as unlikely
upstream will reserve 10+ syscall entrypoints for it...

NAK from me...

cheers, Kyle
