--------------------------------

commit 6f6cb171 upstream.

Patch series "Fix a bunch of allmodconfig errors", v2.

Since b339ec9c ("kbuild: Only default to -Werror if COMPILE_TEST")
WERROR now defaults to COMPILE_TEST meaning that it's enabled for
allmodconfig builds.  This leads to some interesting build failures when
using Clang, each resolved in this set.

With this set applied, I am able to obtain a successful allmodconfig Arm
build.

This patch (of 2):

calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 ||
ARM64) architectures built with Clang (all released versions), whereby the
stack frame gets blown up to well over 5k.  This would cause an immediate
kernel panic on most architectures.  We'll revert this when the following
bug report has been resolved:
https://github.com/llvm/llvm-project/issues/41896.
