For simplicity I would just use it unconditionally when no high_limit is
set. What would be the problem with that? If you look at current users
(and there no new users emerging too often) then most of them just want
_some_ scaling. The original one obviously doesn't scale with large
machines. Are you OK to fold my change to your patch or you want me to
send a separate patch? AFAIK Andrew hasn't posted this patch to Linus
yet.
