[Xen-devel] [PATCH v14 0/9] paravirtual IOMMU pre-requisites and clean-up

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

This series contains pre-requisites and clean-up needed for paravirtual
IOMMU support.

I have separated these patches to avoid further delaying their application
whilst I re-work the implementation of paravirtual IOMMU after review of
v6 of the series. Several of them already have all necessary acks.

v11:
 - Pull in two more patches from v6.

Paul Durrant (9):
  iommu: introduce the concept of DFN...
  iommu: make use of type-safe DFN and MFN in exported functions
  iommu: push use of type-safe DFN and MFN into iommu_ops
  iommu: don't domain_crash() inside iommu_map/unmap_page()
  memory: add check_get_page_from_gfn() as a wrapper...
  vtd: add missing check for shared EPT...
  vtd: add lookup_page method to iommu_ops
  mm / iommu: include need_iommu() test in iommu_use_hap_pt()
  mm / iommu: split need_iommu() into has_iommu_pt() and
    need_iommu_pt_sync()
