[Xen-merge] AMD64 dma-mapping

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

I'm trying enable the IOMMU in AMD Opteron systems
in the linux-2.6-xen.hg codebase.

If I turn on CONFIG_GART_IOMMU in the Kconfig,
enable it in the .config file, and build the 
kernel, I get errors because
include/asm-i386/mach-xen/asm/dma-mapping.h
is included instead of 
include/asm-x86_64/mach-xen/asm/dma-mapping.h

I can't figure out how or where the build system
decides which dma-mapping file to include.  Help
would be appreciated.
