[ 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.

The fix uses MAX() instead of max() in the checksums_onstack[] array declarations. Note: In the mainline branch, checksums_onstack[] used max_t(), so it was fixed to use MAX_T() in commit 4477b39c32fd ("minmax: add a few more MIN_T/MAX_T users"). In 6.1.y, checksums_onstack[] used max(), so it was fixed to use MAX in the backport of commit cb04e8b1d2f2 ("minmax: don't use max() in situations that want a C constant expression").
