Lots of prep stuff for the GTT remapping already landed, so now
we're left with just the real meat: the remapped vma and actually
constructing it.

I spotted that I kinda busted up the skl+ stride_mult stuff for
linear buffers in the BIOS fb takeover path so I included a fix
for that as a separate patch.

Ville Syrjälä (5):
  drm/i915: Decouple SKL stride units from intel_fb_stride_alignment()
  drm/i915: Add a new "remapped" gtt_view
  drm/i915: Overcome display engine stride limits via GTT remapping
  drm/i915: Bump gen4+ fb stride limit to 256KiB
  drm/i915: Bump gen4+ fb size limits to 32kx32k
