I'm also seeing quite a few stack size warnings with KASAN on x86_64
without COMPILT_TEST using gcc 10.2.1 from Debian. In fact there are a
few warnings without KASAN, but with KASAN there are a lot more.
I'll try to find some time to dig into them.
While we're at it, with -Werror something like this is really futile:
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function ‘amdgpu_bo_support_uswc’:
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:493:2: warning: #warning
Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Wcpp
