This allows building cpupower in parallel rather than serially.

Can you please show the make calls, ideally with a timing to better
understand and also to reproduce the advantages this patch introduces.
 From what I can see, it only helps if one calls "sub-install" targets
directly?

That's exactly what we do: make install directly:

/linux-5.10.5$ make -C ./tools/power/cpupower DESTDIR=/tmp/cpupower
install -j $(nproc)

This makes sense then.
@Shuah @Rafael: Can this patch be queued up, please.

Thanks for the patch and the details,

Thank you both.

I applied it 
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux.git/commit/?h=cpupower

Will send this in my next pull request to Rafael.

thanks,
