From afe6804c045fbd69a1b75c681107b5d6df9190de Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 22 Jan 2013 13:56:04 +1000 Subject: [PATCH] ttm: export functions to allow qxl do its own iomapping qxl wants to use io mapping like i915 gem does, for now just export the symbols so the driver can implement atomic page maps using io mapping.
