From ec402ba97a6479dd80488b4404a73275e894289f Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Wed, 18 Nov 2009 10:22:46 +0000 Subject: agp/intel-agp: Set dma_mask for capable chipsets before agp_add_bridge() We should set this before calling agp_add_bridge() so that it's done before we map the scratch page too. This should probably fix the regression reported as k.o. bug #14627.
