Here is another take on iommu_ops on POWER to make VFIO work
again on POWERPC64.

The tree with all prerequisites is here:

Please comment. Thanks.



Alexey Kardashevskiy (3):
  powerpc/iommu: Add "borrowing" iommu_table_group_ops
  powerpc/pci_64: Init pcibios subsys a bit later
  powerpc/iommu: Add iommu_ops to report capabilities and allow blocking
    domains

It has been a little while - and I think this series is still badly
needed by powerpc, right?

Your comments on patch 3 left me with the impression it needed a respin,
but maybe I misread that.

Alexey's reply that it needed testing also made me think it wasn't
ready to pick up.

cheers
