This is so unusual, and I conjecture that linux/kernel.h is broken. I
need to look into the standard C, and see what it really says.

I always took it for granted that INT_MAX and friends are not just
macros. They ought to be macros suitable for use in preprocessor
conditions, before even the compile-time kicks in.
