Move the arch/i386/kernel/swiotlb.c code to lib/swiotlb-xen.c code in order to simplify maintenance of Xen in the future. The first patch simply moves the code to lib/swiotlb-xen.c; the second patch adds the necessary changes to the Xen code base to allow x86_64 systems to boot with SWIOTLB and the dma_ops framework. The first patch also copies the standard arch/x86_64/kernel/pci-dma.c to arch/x86_64/kernel/pci-dma-xen.c, which should make reviewing the second patch a little easier.
