Ah, I missed the tools/ prefix in the patch, sorry.

Well, FWIW, we have hweight32 in <tools/perf/util/hweight.c> too and
there was a patchset preparing a generic kernel tools library where
tools can share functions but the author doesn't have time to dust the
patches off and get it upstream... :-).

I guess having a local function is the easiest for now.

Thanks.
