Yes I explicitly avoided touching parse_cpumask because I don't want to change
behavior of other tools if I'm not confident with that.  Would above two
patches fix oslat too (which I didn't check)?  If so, I'll be fine to have this
patch dropped.  Otherwise I tend to prefer fixing oslat first.  We can further
rework the common code, but if existing tools are fine, then I don't think it's
a bugfix, so no need to rush.  While I'll count this patch as a real bugfix, so
I'd hope we could consider merging it earlier.

As I said, I would really appreciated if all tools behave the same
way. Having oslat be special is going to be pain in the long run. Just
update parse_cpumask, it's not that difficult :)
