I see arch/x86/include/asm/cpufeatures.h patches that also include
a change to tools/arch/x86/include/asm/cpufeatures.h in support
of perf. I do not know the customs here but I see others
change both in the same patch and if it is not done together a separate
patch to tools/arch/x86/include/asm/cpufeatures.h would be required
anyway to address the inevitable perf build warning.
