The series adds support for VFIO on POWERPC in user space (such as QEMU).
The in-kernel real mode IOMMU support is added by another series posted
separately.
As the first and main aim of this series is the POWERNV platform support,
the "Enable on POWERNV platform" patch goes first and introduces an API
to be used by the VFIO IOMMU driver. The "Enable on pSeries platform" patch
simply registers PHBs in the IOMMU subsystem and expects the API to be present,
it enables VFIO support in fully emulated QEMU guests.
These patches were tested against 3.8 and the "iommu: Move initialization earlier"
patch is already in 3.9 so I am including it here only for the reference.
Change log:
* cleanups and minor fixes
* added support for pSeries
* separated from in-kernel IOMMU handling series (should make it easier to get sob'ed)
* signed-off-by Paul Mackerras
