# Merge: 55472bae5331 b5531563e8a0
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     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.
