[PATCH v2 0/6] iommu/s390: support additional table regions

[Matthew Rosato <mjrosato@linux.ibm.com>]

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.

Changes for v2:
- rebase onto 6.13
- remove 'iommu/s390: add basic routines for region 1st and 2nd tables'
  and put routines in first patch that uses each.  No functional change.
