The attached patch unifies pci-dma.c and adds the pte_mfn() macro.
The one thing that might need an explanation, there's 4 lines of changes
(walking the page table) that add parentheses. The x86_64 compiler doesn't
seem to like doing unparenthesized math for function arguments.
Boot tested dom0 on x86_64 and x86_32 (non-pae)
