Whilst I'm still a bit worried about the ability of the IOMMU driver to do
very much in the ->domain_alloc callback (since we don't know which IOMMU
instance the domain is for), it doesn't leave us any worse off than we
currently are.

So, for the arm-smmu patch and the core IOMMU changes:

Hopefully this doesn't conflict too badly with my outstanding arm-smmu
pull requests to you, but do shout if you have any trouble.
