  iommu/core: Remove global iommu_ops and register_iommu
  iommu/msm: Use bus_set_iommu instead of register_iommu
  iommu/omap: Use bus_set_iommu instead of register_iommu

  iommu/core: Use bus->iommu_ops in the iommu-api
  iommu/core: Convert iommu_found to iommu_present
  iommu/core: Add bus_type parameter to iommu_domain_alloc
  Driver core: Add iommu_ops to bus_type
  iommu/core: Define iommu_ops and register_iommu only with CONFIG_IOMMU_API
  iommu/amd: Fix wrong shift direction
  iommu/omap: always provide iommu debug code
  iommu/core: let drivers know if an iommu fault handler isn't installed
  iommu/core: export iommu_set_fault_handler()
  iommu/omap: Fix build error with !IOMMU_SUPPORT
  iommu/omap: Migrate to the generic fault report mechanism
  iommu/core: Add fault reporting mechanism

  iommu/msm: ->unmap() should return order of unmapped page
  ...

Fixup trivial conflicts in drivers/iommu/Makefile: "move omap iommu to
dedicated iommu folder" vs "Rename the DMAR and INTR_REMAP config
options" just happened to touch lines next to each other.
