   hmm, i didn't check, but i did apply your patch and now it works!

   i had noticed this value is tested to choose which mapping method,
   and wondered about it being 2^32, but didn't know what else it should
   be for i386...

   thanks.  Taylor, what do you think?

LGTM.  rjs@ and I discussed this months ago and I lost track of it.
Needs to happen in i915 too, and everywhere else there's copypasta of
it (grep for DRM_FILE_PAGE_OFFSET, or drm_vma_offset_manager_init).
Looks like drm_gem.c will need a slightly different tweak.
