Linus Torvalds f6c0ffa8f0 IOMMU Updates for Linux v3.9
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.

* For drivers that require platform data to be provided from the machine
* file, a platform data pointer can also be supplied along with the
* devices names. Usually, the platform data elements that cannot be parsed
