Heads up to whoever is using or developing for the following kernel branch:

It seems like a recent commit has caused 32bit builds to fail. I haven't
been able to look into it myself or do a bisect, but it seems like it was
something committed between Jan 25th (d0c15b8) and Feb 2nd (99eb22d) caused

Here's the error output:

ERROR: "__udivdi3" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
scripts/Makefile.modpost:91: recipe for target '__modpost' failed
Makefile:1200: recipe for target 'modules' failed
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

After a quick glance, it seems similar to a previous kernel commit:

just a shot in the dark, but it could be caused by this commit:

As it's the only one I see with 64 bit division in it. As I said, shot in
the dark here.
