#     Merge tag 'iommu-fixes-v5.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull iommu fixes from Joerg Roedel:
#     
#      - Fix kmemleak warning in IOVA code
#     
#      - Fix compile warnings on ARM32/64 in dma-iommu code due to dma_mask
#        type mismatches
#     
#      - Make ISA reserved regions relaxable, so that VFIO can assign devices
#        which have such regions defined
#     
#      - Fix mapping errors resulting in IO page-faults in the VT-d driver
#     
#      - Make sure direct mappings for a domain are created after the default
#        domain is updated
#     
#      - Map ISA reserved regions in the VT-d driver with correct permissions
#     
#      - Remove unneeded check for PSI capability in the IOTLB flush code of
#        the VT-d driver
#     
#      - Lockdep fix iommu_dma_prepare_msi()
#
