Since b339ec9c229aa ("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 failures, each resolved in this set. With this set applied, I am able to obtain a successful allmodconfig Arm build. v1 => v2: - Remove superfluous change (these two override it) - Mark only DRM_AMD_DC ("the new display engine) as Broken - Change logic to only *include* working arches, not *preclude* them Lee Jones (2): drm/amdgpu: Temporarily disable broken Clang builds due to blown stack-frame Kconfig.debug: Provide a little extra FRAME_WARN leeway when KASAN is enabled drivers/gpu/drm/amd/display/Kconfig | 7 +++++++ lib/Kconfig.debug | 1 + 2 files changed, 8 insertions(+) -- 2.38.1.584.g0f3c55d4c2-goog
