Applied 1-3 to kvm-x86 pmu.  Note, I grabbed my full version of patch 2 that
also converts the "get" path.

My apologies for not reviewing this earlier in the cycle.  I need to pivot to
TDX+SNP stuff "soon", so AMD v2 support will likely miss 6.4, but I'll prioritize
reviewing and merging support in 6.5.

Thanks!
