From 3e302542055617703b260489ec1ff6fc6f1e68cd Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Tue, 23 Apr 2013 23:15:32 -0700 Subject: [PATCH] drm/i915: Extract PDE writes It also makes some sense IMO to have these two functions separate irrespective of the number of callers. Only the single caller for now, but that will change as we add more PPGTTs.
