The "suggestion" is to not update the headers that perf tooling copies verbatim from the kernel, e.g. tools/include/uapi/linux/kvm.h. The duplicates in tools/ aren't used by KVM selftests, it's purely perf that needs identical copies from the kernel tree, so I strongly prefer to leave it to the perf folks to deal with synchronizing the headers as needed.

This header is a KVM selftests specific header that is independent from the kernel headers. It does have _some_ copy+paste, mostly for architecturally defined bits and bobs, but it's not a straight copy of any kernel header.
That said, yes, I think we should also clean up x86_64/processor.h. That can be done in a one-off standalone patch though.
