From 459121c9ec1e6c5d701f6520f4170719ac008951 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Tue, 8 Apr 2008 13:20:43 -0300 Subject: [PATCH] x86: introduce pci-dma.c This patch introduces pci-dma.c, a common file for pci dma between i386 and x86_64. As a start, dma_set_mask() is the same between architectures, and is placed there.
