Pull iommu fixes from Joerg Roedel:

 - A couple more fixes for the Intel VT-d driver for bugs introduced
   during the recent conversion of this driver to use IOMMU core default
   domains.

 - Fix for common dma-iommu code to make sure MSI mappings happen in the
   correct domain for a device.

 - Fix a corner case in the handling of sg-lists in dma-iommu code that
   might cause dma_length to be truncated.

 - Mark a switch as fall-through in arm-smmu code.
