[PATCH 0/5] iommu: Domain allocation enhancements

[Vasant Hegde <vasant.hegde@amd.com>]

This series adds iommu_paging_domain_alloc_flags() which takes flags to
pass additional details for domain allocation (like domain with PASID
support).

Also updates AMD IOMMU driver domain allocation code. With this by
default it will allocate domain with V2 page table for PASID capable
device and v1 page table for rest of the devices.

@Baolu,
  With this changes (patch 1), to allocate PASID capable domain, core
  will call domain_alloc_user() interface. Do we need any changes to
  intel driver?

@Yi,
  I think we can look into iommufd related changes once this serires is
  finalized.
