Regarding the claim that this would work for 32-bit x86 builds:
make ARCH=i386 allmodconfig
make ARCH=i386 drivers/gpu/drm/amd/amdgpu/amdgpu_device.o
results in:
...
CC [M] drivers/gpu/drm/amd/amdgpu/amdgpu_device.o
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c: In function ‘amdgpu_mm_rreg64’:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:279:9: error: implicit declaration of function ‘readq’;
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c: In function ‘amdgpu_mm_wreg64’:
drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:298:3: error: implicit declaration of function ‘writeq’
This is with next-20190808.
