Subject[PATCH v1] iommu/s390: Declare s390 iommu reserved regions
Date
The s390 iommu can only allow DMA transactions between the zPCI device
entries start_dma and end_dma.

Let's declare the regions before start_dma and after end_dma as
reserved regions using the appropriate callback in iommu_ops.

The reserved region may later be retrieved from sysfs or from
the vfio iommu internal interface.

This seems to me related with the work Shameer has started on
vfio_iommu_type1 so I add Alex and Shameer to the CC list.
