Subject: [PATCH 9/9] kbuild: enable tautological-constant-out-of-range-compare

From: Arnd Bergmann <arnd@...db.de>

All the previously reported warnings from this option have been addressed,
so the option can now be left default-enabled, rather than disabled without
W=1. There are not too many actual bugs found by this, but it can help
detect a silly mistake earlier, and it's usually trivial to work around
the false-positives.
