This is unconditionally asking for asm/perf_regs.h and it is not available
everywhere, so I think this has to be abstracted away, maybe using a weak
function that arm provides a replacement for?

Is this for doing cross-platform analysis? I.e. record a perf.data file
on arm64 and then do a perf-report on it on a x86_64 machine? Yeah, that
is expected to work, but then:
