From e85b26dc1ca5ecbf6456c61a131a986a755cbc69 Mon Sep 17 00:00:00 2001 From: John Harrison Date: Fri, 29 May 2015 17:43:56 +0100 Subject: [PATCH] drm/i915: Update switch_mm() to take a request structure Updated the switch_mm() code paths to take a request instead of a ring. This includes the myriad *_mm_switch functions themselves and a bunch of PDP related helper functions. v2: Rebased to newer tree.
