Merge tag 'iommu-updates-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
"This time including:
- A new IOMMU driver for s390 pci devices
- Common dma-ops support based on iommu-api for ARM64. The plan is
to use this as a basis for ARM32 and hopefully other architectures
as well in the future.
- MSI support for ARM-SMMUv3
- Cleanups and dead code removal in the AMD IOMMU driver
- Better RMRR handling for the Intel VT-d driver
- Various other cleanups and small fixes"
