Pull iommu fixes from Joerg Roedel:

 - Fix kmemleak warning in IOVA code

 - Fix compile warnings on ARM32/64 in dma-iommu code due to dma_mask
   type mismatches

 - Make ISA reserved regions relaxable, so that VFIO can assign devices
   which have such regions defined

 - Fix mapping errors resulting in IO page-faults in the VT-d driver

 - Make sure direct mappings for a domain are created after the default
   domain is updated

 - Map ISA reserved regions in the VT-d driver with correct permissions

 - Remove unneeded check for PSI capability in the IOTLB flush code of
   the VT-d driver

 - Lockdep fix iommu_dma_prepare_msi()
