Subject: [PATCH 06/15 6.6.y] minmax: don't use max() in situations that want a C constant expression
From: Linus Torvalds <torvalds@...ux-foundation.org>
[ Upstream commit cb04e8b1d2f24c4c2c92f7b7529031fc35a16fed ]
We only had a couple of array[] declarations, and changing them to just
use 'MAX()' instead of 'max()' fixes the issue.
This will allow us to simplify our min/max macros enormously, since they
can now unconditionally use temporary variables to avoid using the
argument values multiple times.
