Subject: [PATCH 0/9] address remaining -Wtautological-constant-out-of-range-compare

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

The warning option was introduced a few years ago but left disabled
by default. All of the actual bugs that this has found have been
fixed in the meantime, and this series should address the remaining
false-positives, as tested on arm/arm64/x86 randconfigs as well as
allmodconfig builds for all architectures supported by clang.

Please apply the patches individually to subsystem maintainer trees.
