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."

This option sets IPMMU/IPMMUI address space size by
adjusting the 1st level page table size. The page table size
is calculated as follows:
page table size = number of page table entries * 4 bytes
number of page table entries = address space size / 1 MiB
For example, when the address space size is 2048 MiB, the
1st level page table size is 8192 bytes.
