This patchset convert the PPC64 IOMMU to use the iova code for free area management.
The IOMMUs ignores low level drivers' restrictions, the maximum segment size and segment boundary.
I fixed the former:

The latter makes the free area management complicated. I'd like to convert IOMMUs to use the iova code (that intel-iommu introduced) for free area management and enable iova to handle segment boundary restrictions, rather than fixing all the IOMMUs' free area management,
I converted the PPC64 IOMMU to see how things work. The patchset was slightly tested with a pSeries box and seems to work.
This is against the latest Linus' git tree with David Miller's genericizing iova patch:
