From 32ecd24264542328893e8649312c301150dbadc5 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 30 Jul 2012 14:06:55 +1000 Subject: [PATCH] drm/udl: call begin/end cpu access at more appropriate time We need to call these before we transfer the damaged areas to the device not before/after we setup the long lived vmaps.
