Another posting of the gtt remapping series. This time with Chris's idea
of forcing gtt remapping for ci. A slight gap in that testing comes from
the fact that igt will not align linear stride to 4k for non-dumb
buffers. I'd need to pair this with an igt patch to make that happen.

Apart from the hacks the only change from v2 is dealing with
fallout from intel_wakeref_t.

Force pushed on top of the last attempt:
git://github.com/vsyrjala/linux.git fb_vma_remap_13                                                                    

Ville Syrjälä (8):
  drm/i915: Add a new "remapped" gtt_view
  drm/i915/selftests: Add mock selftest for remapped vmas
  drm/i915/selftests: Add live vma selftest
  drm/i915: Overcome display engine stride limits via GTT remapping
  drm/i915: Bump gen4+ fb stride limit to 256KiB
  drm/i915: Bump gen7+ fb size limits to 16kx16k
  hack: drm/i915: Always remap gtt
  hack: align dumb buffer stride to 4k to allow for gtt remapping
