The framework allows callable implementation of IO page table.
This allows AMD IOMMU driver to switch between different types
of AMD IOMMU page tables (e.g. v1 vs. v2).
This series refactors the current implementation of AMD IOMMU v1 page table
to adopt the framework. There should be no functional change.
Subsequent series will introduce support for the AMD IOMMU v2 page table.
Thanks,
