[PATCH 0/7] iommu/s390: support additional table regions

[Matthew Rosato]

The series extends the maximum table size allowed by s390-iommu by
increasing the number of table regions supported.  It also adds logic to
construct the table use the minimum number of regions based upon aperture
calculation.

Matthew Rosato (7):
  iommu/s390: add initial fields to track table size
  s390/pci: set appropriate IOTA region type
  iommu/s390: add basic routines for region 1st and 2nd tables
  iommu/s390: support cleanup of additional table regions
  iommu/s390: support iova_to_phys for additional table regions
  iommu/s390: support map/unmap for additional table regions
  iommu/s390: allow larger region tables
