So this now broke drm-misc-next compilation on arm, which isn't great.
Please make sure you compile test stuff before pushing.

Since the proper fix is maybe stuck in the usual "drm abuses swiotlb
internals" bikeshed, maybe best if we push a fix to including limits.h
in nouveau and call it done? Also adding Maxime, who's trying to get
the backmerge through right now.
