Hey Jean-Philippe,
thanks for the patch, I think we are on the finish line with this
interface. Just one small question below.

What is the purpose of the sva_set_ops call-back in iommu-ops? Is the
IOMMU driver supposed to do some extra setup work with the provided ops?
Otherwise we can just store the pointer in 'struct iommu_sva' without
calling into the iommu driver.

Joerg
