SubjectRe: [PATCH 1/2] tools, perf: Add a precise event qualifier v2

The problem is they want the ABI to be "whatever our closely-coupled
userspace perf tool accepts as input" which is an often-changing
complicated (and undocumented) set of LEX and YACC parsers.

I guess we could just give in and declare that to be the official
perf sysfs interface in the ABI documentation.

It's frustrating trying to maintain tools that use the perf_event
interface because the inclusion of perf in the kernel is used as an excuse
to constantly break the ABI.
