[GIT PULL] iommu/arm-smmu: updates for 3.18

[Will Deacon]

Hi Joerg,

Please can you pull these arm-smmu updates for 3.18? Apologies for sending
this later than usual, but I was at a conference last week and couldn't
easily run the usual series of tests.

The main changes are:

  - Explicit support for MMU-401 (as opposed to choosing an SMMU
    architecture version)
  - Some address size fixes that became apparent when running under KVM
  - A new debugging option to force the use of stage-1 or stage-2 only
  - A fix for a benign bug in the page table code
  - Initial support for multi-master IOMMU groups, but there is likely
    more to come in this area

Thanks,

Will

Pulled, thanks Will.
