From: Ben Widawsky Date: Thu, 27 Jun 2013 23:30:17 +0000 (-0700) Subject: drm/i915: Really share scratch page X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=84f135605898708ab692fc84555c31fbfe2983c1;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Really share scratch page A previous patch had set up the ppgtt and ggtt to use the same scratch page, but still kept around both pointers. Kill it, it's not needed and gets in our way for upcoming cleanups.
