If anyone has any objections, please let me know. ------------------ From: Linus Torvalds [ 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.
