Merge tag 'iommu-updates-v5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates from Joerg Roedel:

 - ARM-SMMU Updates from Will:

      - Continued SVM enablement, where page-table is shared with CPU

      - Groundwork to support integrated SMMU with Adreno GPU

      - Allow disabling of MSI-based polling on the kernel command-line

      - Minor driver fixes and cleanups (octal permissions, error
        messages, ...)

 - Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when
   a device tries DMA on memory owned by a guest. This needs new
   fault-types as well as a rewrite of the IOMMU memory semaphore for
   command completions.

 - Allow broken Intel IOMMUs (wrong address widths reported) to still be
   used for interrupt remapping.

 - IOMMU UAPI updates for supporting vSVA, where the IOMMU can access
   address spaces of processes running in a VM.

 - Support for the MT8167 IOMMU in the Mediatek IOMMU driver.

 - Device-tree updates for the Renesas driver to support r8a7742.

 - Several smaller fixes and cleanups all over the place.
