From 90d0a0e8d0e64c92c4a6147f3c7cdc7c544d6b1a Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 6 Aug 2014 15:04:56 +0200 Subject: [PATCH] drm/i915: Extract commmon global gtt cleanup code We want to move the aliasing ppgtt cleanup back into the global gtt cleanup code for symmetry, but first we need to create such a place.
