Thread-topic: [PATCH][retry 2] Make x86_64 swiotlb code to support dma_ops [2/2]
As per Keir's and Jan's suggestions, I'm simplifying 
my approach to getting GART into the kernel.  This 
patch set makes the x86_64 swiotlb code work with 

The first patch creates the 
arch/x86_64/kernel/pci-dma-xen.c file based on the 
standard pci-dma.c.

The second patch modifies 
arch/x86_64/kernel/pci-swiotlb-xen.c to work with 
dma_ops, and modifies arch/x86_64/kernel/pci-dma-xen.c
slightly to be Xen-safe by copying over some functions
from arch/i386/kernel/pci-dma-xen.c
