X-Git-Tag: v2.6.31-rc3~25^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d05ca301997c94c2ef3c112b15319d13fa8cddab;p=pandora-kernel.git drm/i915: Zap the GTT mapping when transitioning from untiled to tiled. As of 52dc7d32b88156248167864f77a9026abe27b432, we could leave an old linear GTT mapping in place, so that apps trying to GTT-mapped write in tiled data wouldn't get the fence added, and garbage would get displayed.
