[PATCH 0/3] Remove accidental VLA usage

[Kees Cook]

This series adds SIMPLE_MAX() to be used in places where a stack array
is actually fixed, but the compiler still warns about VLA usage due to
confusion caused by the safety checks in the max() macro.

I'm sending these via -mm since that's where I've introduced SIMPLE_MAX(),
and they should all have no operational differences.
