Hey,

here are two patches for the s390 PCI and IOMMU code. It is
based on the assumption that every pci_dev that points to
the same zpci_dev shares a single dma-table (and thus a
single address space).

If this assupmtion is true (as it looks to me from reading
the code) then the iommu-group setup code in the s390 iommu
driver needs to be updated.

These patches do this and also add support for the
iommu_device_register interface to the s390 iommu driver.

Any comments and testing appreciated.

Thanks,

	Joerg
