Subject[PATCH] x86/perf_events: build fix
At least some older gcc versions dislike mixing constant and non-const
data in the same section ("... causes a section type confict"). Newer
gcc simply emits the section as writable (which isn't what we want, but
also is not a big problem as it gets discarded post-init anyway).

Also get the Knight's Corner definitions in sync.
