    Merge tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu · a13f0655
    Linus Torvalds authored
    Pull IOMMU updates from Joerg Roedel:
    
     - ATS support for ARM-SMMU-v3.
    
     - AUX domain support in the IOMMU-API and the Intel VT-d driver. This
       adds support for multiple DMA address spaces per (PCI-)device. The
       use-case is to multiplex devices between host and KVM guests in a
       more flexible way than supported by SR-IOV.
    
     - the rest are smaller cleanups and fixes, two of which needed to be
       reverted after testing in linux-next.
