Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (33 commits) 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/vt-d: Use bus_set_iommu instead of register_iommu iommu/amd: 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/core: Use PAGE_SIZE instead of hard-coded value iommu/core: use the existing IS_ALIGNED macro 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.
