Hmm. It reverts cleanly, but the end result doesn't work, because of
other changes.

Reverting all of

   763fedd6a216 ("drm/i915: Remove i915_gem_object_get_dirty_page()")
   7ac2d2536dfa ("drm/i915/gem: Delete unused code")
   9e0f9464e2ab ("drm/i915/gem: Async GPU relocations only")

seems to at least build.

Pavel, does doing those three reverts make things work for you?
