SubjectRe: [PATCH] perf_counter: remove the event config bitfields
Peter Zijlstra writes:

Yep. That doesn't get assigned directly to a hardware register; it
undergoes further processing first, which just pulls out the bits it
needs. (It's not used directly because the hardware has a couple of
registers that configure all the counters at once, rather than a
configuration register per counter.)
