IOMMU Updates for Linux v5.6
Including:
- Allow to compile 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.
