This is definitely long overdue, so thanks for taking this on. I think
minmax.h is fine as a header on its own, but for the other one, I think
you should go even further - and perhaps all these should go in a
include/math/ dir (include/linux/ has ~1200 files), so we'd have
math/minmax.h, math/round.h, math/ilog2.h, math/gcd.h etc., each
containing just enough #includes to be self-contained (so if there's a
declaration of something taking a u32, there's no way around having it
include types.h (or wherever that's defined).
