The only issue is cpufeatures.h as that would create a third copy of it: there is one already at tools/arch/x86/include/asm/cpufeatures.h. Note that we can't move cpufeatures.h from tools/arch/x86/include/asm to tools/testing/selftests/kvm as it's already included by others like tools/perf. > so that we can be sure that > a maintainer (me) runs the script and keeps them up to date.

I'll try this approach for the next version: copy the new headers to tools/testing/selftests/kvm (except cpufeatures.h), and add the script.
