Subject: drm/i915: Remove obj->pin_mappable
X-Git-Tag: firefly_0821_release~176^2~1470^2~58^2~66
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=30154650b8b58cd2633475d5a730b44baa140d98;p=firefly-linux-kernel-4.4.55.git
drm/i915: Remove obj->pin_mappable
The obj->pin_mappable flag only exists for debug purposes and is a
hindrance that is mistreated with rotated GGTT views. For debug
purposes, it suffices to mark objects with pin_display as being of note.
