Merge tag 'iommu-updates-v4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
"The updates include:
- rate limiting for the VT-d fault handler
- remove statistics code from the AMD IOMMU driver. It is unused and
should be replaced by something more generic if needed
- per-domain pagesize-bitmaps in IOMMU core code to support systems
with different types of IOMMUs
- support for ACPI devices in the AMD IOMMU driver
- 4GB mode support for Mediatek IOMMU driver
- ARM-SMMU updates from Will Deacon:
- support for 64k pages with SMMUv1 implementations (e.g MMU-401)
- remove open-coded 64-bit MMIO accessors
- initial support for 16-bit VMIDs, as supported by some ThunderX
SMMU implementations
- a couple of errata workarounds for silicon in the field
- various fixes here and there"
