Hi Joerg,

I'm sending this pull request now because I'm away next week, but here
are the arm-smmu updates I have for 4.4

Changes include:

  * MSI support for the SMMUv3 driver
  * Removal of the smmu_devices list from the SMMUv3 driver
  * Workaround for an SMMUv3  hardware issue on Cavium ThunderX
  * Some minor fixes and cleanups

Please pull,

Will
