I see:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/powerpc/kvm/trace_book3s.h
Would it make sense to have a copy in perf and use the check headers
code to keep them in sync?
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/check-headers.sh

Could you add the commits that add the H_VIRT and H_FAC_UNAVAIL
definitions? I don't see them in Linus' tree yet.

Thanks,
Ian
