Merge tag 'iommu-updates-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- code optimizations for the Intel VT-d driver
- ability to switch off a previously enabled Intel IOMMU
- support for 'struct iommu_device' for OMAP, Rockchip and Mediatek
IOMMUs
- header optimizations for IOMMU core code headers and a few fixes that
became necessary in other parts of the kernel because of that
- ACPI/IORT updates and fixes
- Exynos IOMMU optimizations
- updates for the IOMMU dma-api code to bring it closer to use per-cpu
iova caches
- new command-line option to set default domain type allocated by the
iommu core code
- another command line option to allow the Intel IOMMU switched off in
a tboot environment
- ARM/SMMU: TLB sync optimisations for SMMUv2, Support for using an
IDENTITY domain in conjunction with DMA ops, Support for SMR masking,
Support for 16-bit ASIDs (was previously broken)
- various other small fixes and improvements
