From d200cda6bd9f7553cd83dee261ff593d6386aa0a Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 28 Apr 2016 09:56:44 +0100 Subject: [PATCH] drm/i915: Remove early l3-remap Since we do the l3-remap on context switch, we can remove the redundant early call to set the mapping prior to performing the first context switch.
