Lee Jones 6f6cb17143 drm/amdgpu: temporarily disable broken Clang builds due to blown stack-frame 
Patch series "Fix a bunch of allmodconfig errors", v2.

Since b339ec9c22 ("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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
