Hi All,

This is an updated version of the Xen dom0 PCI access changes with:
- various comments resolved
- acked/reviewed-by tags added
- misc cleanups in patch structure

Ingo, if this is satisfactory with everyone, please pull into
tip/x86/xen/dom0/pci.

(I'll mail the swiotlb changes separately, but they're really part of
the same branch.)

Thanks,
J
