Merge tag 'iommu-updates-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: - code optimizations for the Intel VT-d driver - ability to switch off a previously enabled Intel IOMMU - support for 'struct iommu_device' for OMAP, Rockchip and Mediatek IOMMUs - header optimizations for IOMMU core code headers and a few fixes that became necessary in other parts of the kernel because of that - ACPI/IORT updates and fixes - Exynos IOMMU optimizations - updates for the IOMMU dma-api code to bring it closer to use per-cpu iova caches - new command-line option to set default domain type allocated by the iommu core code - another command line option to allow the Intel IOMMU switched off in a tboot environment - ARM/SMMU: TLB sync optimisations for SMMUv2, Support for using an IDENTITY domain in conjunction with DMA ops, Support for SMR masking, Support for 16-bit ASIDs (was previously broken) - various other small fixes and improvements * tag 'iommu-updates-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (63 commits) soc/qbman: Move dma-mapping.h include to qman_priv.h soc/qbman: Fix implicit header dependency now causing build fails iommu: Remove trace-events include from iommu.h iommu: Remove pci.h include from trace/events/iommu.h arm: dma-mapping: Don't override dma_ops in arch_setup_dma_ops() ACPI/IORT: Fix CONFIG_IOMMU_API dependency iommu/vt-d: Don't print the failure message when booting non-kdump kernel iommu: Move report_iommu_fault() to iommu.c iommu: Include device.h in iommu.h x86, iommu/vt-d: Add an option to disable Intel IOMMU force on iommu/arm-smmu: Return IOVA in iova_to_phys when SMMU is bypassed iommu/arm-smmu: Correct sid to mask iommu/amd: Fix incorrect error handling in amd_iommu_bind_pasid() iommu: Make iommu_bus_notifier return NOTIFY_DONE rather than error code omap3isp: Remove iommu_group related code iommu/omap: Add iommu-group support iommu/omap: Make use of 'struct iommu_device' iommu/omap: Store iommu_dev pointer in arch_data iommu/omap: Move data structures to omap-iommu.h iommu/omap: Drop legacy-style device support ...
