From ba3139f2577eee24479db73b8dfc7d78eaf4c486 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Wed, 5 Aug 2009 08:12:40 +0100 Subject: intel-agp: Set dma mask for i915 If DMAR is configured in but absent, we really do want to make sure that the dma mask is set appropriately. Otherwise we get mapping failures on highmem. Spotted by Zhenyu Wang.
