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:
