This patch breaks i386_defconfig with both GCC and clang:

ld: drivers/gpu/drm/i915/i915_scatterlist.o: in function `i915_rsgt_from_mm_node':
i915_scatterlist.c:(.text+0x1a7): undefined reference to `__udivdi3'

ld.lld: error: undefined symbol: __udivdi3
>>> referenced by i915_scatterlist.c
>>> gpu/drm/i915/i915_scatterlist.o:(i915_rsgt_from_mm_node) in archive drivers/built-in.a

It was reported by Stephen in -next [1] and there is a fix [2] that
works for me but it doesn't appear to be applied yet (at least, it is
not in drm-intel-fixes at the moment). It is a little disappointing to
see new build errors being introduced before -rc7, especially when
visible with a defconfig...
