Hi Gerald,
thanks for your patch. It looks pretty good and addresses my previous
review comments. I have a few questions, first one is how this
operates with DMA-API on s390. Is there a seperate DMA-API
implementation besides the IOMMU-API one for PCI devices?
My other question is inline:

Instead of using your own struct here, have you considered using the
struct iommu_group instead? The struct devices contains a pointer to an
iommu_group and the struct itself contains pointers to the domain it is
currently bound to.
Regards,
Joerg
