4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ville Syrjälä ville.syrjala@linux.intel.com
commit f6e35cda66146106cfeb85ed65696e0f8e793fee upstream.
Use I915_GTT_PAGE_SIZE when talking about GTT pages rather than physical pages.
There are some PAGE_SHIFTs left though. Not sure if we want to introduce I915_GTT_PAGE_SHIFT or what?
