Hi Arnd!
Thanks for bisecting this issue.
I wonder whether you are going to commit your patch or planning to update it
and it's still in your work queue. We have one of our 32-bit builds

On 32-bit architectures, dividing a 64-bit integer in the kernel
leads to a link error:
ERROR: "__udivdi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
ERROR: "__divdi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
Change the two recently introduced instances to a multiply+shift
