Merge tag 'iommu-updates-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU Updates from Joerg Roedel:
"Besides some fixes and cleanups in the code there are three more
important changes to point out this time:
* New IOMMU driver for the ARM SHMOBILE platform
* An IOMMU-API extension for non-paging IOMMUs (required for
upcoming PAMU driver)
* Rework of the way the Tegra IOMMU driver accesses its
registetrs - register windows are easier to extend now.
There are also a few changes to non-iommu code, but that is acked by
the respective maintainers."
