I don't know where this complaint comes from. When I follow the steps
above to reproduce, I find myself failing on code unrelated to my patch
set so I can get my code compiled:

I think the reason for the complaint comes from usage of DIV_ROUND_UP()
which somehow does not work on mips.
I can try to avoid using this macro and implement something of my own,
unless someone has a better idea what's going on here.
