[GIT PULL] iommu/arm-smmu: Updates for 4.3

[Will Deacon]

Hi Joerg,

Here are the arm-smmu and io-pgtable updates I have for 4.3. Main
changes include:

  * Preparation for MSI support for SMMUv3 devices (full support will
    likely come in 4.4, since the IRQ core needs some work to support
    non-PCI devices).

  * A couple of minor fixes in the SMMUv3 driver

  * Support for the dma-coherent propery on SMMUv1/2 devices

  * Removal of the DMA API abuse for flushing page tables out to a
    non-coherent walker. This raised some questions about the DMA API
    Documentation, so I've put these last in the series in case you
    decide not to include them (but I think they're a welcome clean-up).

Please pull,

Will
