Merge tag 'iommu-updates-v6.16' of git://git./linux/kernel/git/iommu/linux

Pull iommu updates from Joerg Roedel:
 "Core:
   - Introduction of iommu-pages infrastructure to consolitate
     page-table allocation code among hardware drivers. This is
     ground-work for more generalization in the future
   - Remove IOMMU_DEV_FEAT_SVA and IOMMU_DEV_FEAT_IOPF feature flags
   - Convert virtio-iommu to domain_alloc_paging()
   - KConfig cleanups
   - Some small fixes for possible overflows and race conditions

  Intel VT-d driver:
   - Restore WO permissions on second-level paging entries
   - Use ida to manage domain id
   - Miscellaneous cleanups

  AMD-Vi:
   - Make sure notifiers finish running before module unload
   - Add support for HTRangeIgnore feature
   - Allow matching ACPI HID devices without matching UIDs

  ARM-SMMU:
   - SMMUv2:
      - Recognise the compatible string for SAR2130P MDSS in the
        Qualcomm driver, as this device requires an identity domain
      - Fix Adreno stall handling so that GPU debugging is more robust
        and doesn't e.g. result in deadlock
   - SMMUv3:
      - Fix ->attach_dev() error reporting for unrecognised domains
   - IO-pgtable:
      - Allow clients (notably, drivers that process requests from
        userspace) to silence warnings when mapping an already-mapped
        IOVA

  S390:
   - Add support for additional table regions

  Mediatek:
   - Add support for MT6893 MM IOMMU

  And some smaller fixes and improvements in various other drivers"
