[PATCH 0/4] Fix compilation issues when using i386

[Rodrigo Siqueira]

Fix compilation issues when using i386

We recently got feedback from Randy about issues in the x86-32
compilation.I was able to reproduce a very similar issue by using:

- gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
- make -j16 ARCH=i386
- amd-staging-drm-next

I'm able to see these issues:

ERROR: modpost: "__nedf2" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! 
ERROR: modpost: "__muldf3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! 
ERROR: modpost: "__floatunsidf" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! 
ERROR: modpost: "__umoddi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!

This patchset addresses each compilation issue in its own patch since I
want to have an easy way to bisect display code in case of regressions.
Please, let me know if you see any issue with these changes and if it
fixes the 32-bit compilation. If you still see compilation issues,
please, report:

- GCC version
- Config file
- Branch

Thanks
Siqueira
