Subject: util: move ALIGN/ROUND_DOWN_TO to u_math.h
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=ae7da1a01706835120bd59ea069e49cf325feaa3

util: move ALIGN/ROUND_DOWN_TO to u_math.h

These are less mesa specific than the rest of macros.h, and would be
nice to use outside of mesa.  Prep for next patch.
