#      "IOMMU core:
#     
#        - Fix for a regression which could cause NULL-ptr dereferences
#     
#       Arm SMMU:
#     
#        - Fix off-by-one in SMMUv3 SVA TLB invalidation
#     
#        - Disable large mappings to workaround nvidia erratum
#     
#       Intel VT-d:
#     
#        - Handle PCI stop marker messages in IOMMU driver to meet the
#          requirement of I/O page fault handling framework.
#     
#        - Calculate a feasible mask for non-aligned page-selective IOTLB
#          invalidation.
