[Xen-devel] [PATCH] retry 3: use i386 swiotlb code in lib/swiotlb-xen.c [1/2]

["Langsdorf, Mark" <mark.langsdorf@xxxxxxx>]

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.
