Pull iommu updates from Joerg Roedel: - SMMU Updates from Will Deacon: - SMMUv3: - Support stalling faults for platform devices - Decrease defaults sizes for the event and PRI queues - SMMUv2: - Support for a new '->probe_finalize' hook, needed by Nvidia - Even more Qualcomm compatible strings - Avoid Adreno TTBR1 quirk for DB820C platform - Intel VT-d updates from Lu Baolu: - Convert Intel IOMMU to use sva_lib helpers in iommu core - ftrace and debugfs supports for page fault handling - Support asynchronous nested capabilities - Various misc cleanups - Support for new VIOT ACPI table to make the VirtIO IOMMU available on x86 - Add the amd_iommu=force_enable command line option to enable the IOMMU on platforms where they are known to cause problems - Support for version 2 of the Rockchip IOMMU - Various smaller fixes, cleanups and refactorings * tag 'iommu-updates-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (66 commits) iommu/virtio: Enable x86 support iommu/dma: Pass address limit rather than size to iommu_setup_dma_ops() ACPI: Add driver for the VIOT table ACPI: Move IOMMU setup code out of IORT ACPI: arm64: Move DMA setup operations out of IORT iommu/vt-d: Fix dereference of pointer info before it is null checked iommu: Update "iommu.strict" documentation iommu/arm-smmu: Check smmu->impl pointer before dereferencing iommu/arm-smmu-v3: Remove unnecessary oom message iommu/arm-smmu: Fix arm_smmu_device refcount leak in address translation iommu/arm-smmu: Fix arm_smmu_device refcount leak when arm_smmu_rpm_get fails iommu/vt-d: Fix linker error on 32-bit iommu/vt-d: No need to typecast iommu/vt-d: Define counter explicitly as unsigned int iommu/vt-d: Remove unnecessary braces iommu/vt-d: Removed unused iommu_count in dmar domain iommu/vt-d: Use bitfields for DMAR capabilities iommu/vt-d: Use DEVICE_ATTR_RO macro iommu/vt-d: Fix out-bounds-warning in intel/svm.c iommu/vt-d: Add PRQ handling latency sampling ...
