IOMMU Fixes for Linux v5.3-rc4
Including:
- A couple more fixes for the Intel VT-d driver for bugs
introduced during the recent conversion of this driver to use
IOMMU core default domains.
- Fix for common dma-iommu code to make sure MSI mappings happen
in the correct domain for a device.
- Fix a corner case in the handling of sg-lists in dma-iommu
code that might cause dma_length to be truncated.
- Mark a switch as fall-through in arm-smmu code.
iommu/vt-d: Fix possible use-after-free of private domain
Multiple devices might share a private domain. One real example
is a pci bridge and all devices behind it. When remove a private
domain, make sure that it has been detached from all devices to
avoid use-after-free case.
