Merge tag 'iommu-updates-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "This time with: - Generic page-table framework for ARM IOMMUs using the LPAE page-table format, ARM-SMMU and Renesas IPMMU make use of it already. - Break out the IO virtual address allocator from the Intel IOMMU so that it can be used by other DMA-API implementations too. The first user will be the ARM64 common DMA-API implementation for IOMMUs - Device tree support for Renesas IPMMU - Various fixes and cleanups all over the place" * tag 'iommu-updates-v3.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (36 commits) iommu/amd: Convert non-returned local variable to boolean when relevant iommu: Update my email address iommu/amd: Use wait_event in put_pasid_state_wait iommu/amd: Fix amd_iommu_free_device() iommu/arm-smmu: Avoid build warning iommu/fsl: Various cleanups iommu/fsl: Use %pa to print phys_addr_t iommu/omap: Print phys_addr_t using %pa iommu: Make more drivers depend on COMPILE_TEST iommu/ipmmu-vmsa: Fix IOMMU lookup when multiple IOMMUs are registered iommu: Disable on !MMU builds iommu/fsl: Remove unused fsl_of_pamu_ids[] iommu/fsl: Fix section mismatch iommu/ipmmu-vmsa: Use the ARM LPAE page table allocator iommu: Fix trace_map() to report original iova and original size iommu/arm-smmu: add support for iova_to_phys through ATS1PR iopoll: Introduce memory-mapped IO polling macros iommu/arm-smmu: don't touch the secure STLBIALL register iommu/arm-smmu: make use of generic LPAE allocator iommu: io-pgtable-arm: add non-secure quirk ...
