X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1a82081db6e57eaa74f852ed8acb391a7f4c2ca6;p=mesa.git mesa: Move ROUND_DOWN_TO() macro from i915/i965 to macros.h. This seems generally useful, so it may as well live in core Mesa. In fact, the comment for ALIGN() in macros.h actually says to "see also" ROUND_DOWN_TO, which...was in a driver somewhere.
