Imre Deak	9755f055f5	drm/i915: Restore memory mapping for DPT FBs across system suspend/resume ... At least during hibernation the DPT mappings are lost with all stolen memory content, so suspend/resume these mappings similarly to GGTT mappings. This fixes a problem where the restoring modeset during system resume fails with pipe faults if a tiled framebuffer was active before suspend. v2: Clarify the way restore works in intel_dpt_resume()'s Docbook entry.
