Merge tag 'iommu-updates-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - Allow compiling the ARM-SMMU drivers as modules. - Fixes and cleanups for the ARM-SMMU drivers and io-pgtable code collected by Will Deacon. The merge-commit (6855d1ba7537) has all the details. - Cleanup of the iommu_put_resv_regions() call-backs in various drivers. - AMD IOMMU driver cleanups. - Update for the x2APIC support in the AMD IOMMU driver. - Preparation patches for Intel VT-d nested mode support. - RMRR and identity domain handling fixes for the Intel VT-d driver. - More small fixes and cleanups. * tag 'iommu-updates-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (87 commits) iommu/amd: Remove the unnecessary assignment iommu/vt-d: Remove unnecessary WARN_ON_ONCE() iommu/vt-d: Unnecessary to handle default identity domain iommu/vt-d: Allow devices with RMRRs to use identity domain iommu/vt-d: Add RMRR base and end addresses sanity check iommu/vt-d: Mark firmware tainted if RMRR fails sanity check iommu/amd: Remove unused struct member iommu/amd: Replace two consecutive readl calls with one readq iommu/vt-d: Don't reject Host Bridge due to scope mismatch PCI/ATS: Add PASID stubs iommu/arm-smmu-v3: Return -EBUSY when trying to re-add a device iommu/arm-smmu-v3: Improve add_device() error handling iommu/arm-smmu-v3: Use WRITE_ONCE() when changing validity of an STE iommu/arm-smmu-v3: Add second level of context descriptor table iommu/arm-smmu-v3: Prepare for handling arm_smmu_write_ctx_desc() failure iommu/arm-smmu-v3: Propagate ssid_bits iommu/arm-smmu-v3: Add support for Substream IDs iommu/arm-smmu-v3: Add context descriptor tables allocators iommu/arm-smmu-v3: Prepare arm_smmu_s1_cfg for SSID support ACPI/IORT: Parse SSID property of named component node ...
