#     Merge tag 'iommu-updates-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
#     
#     Pull IOMMU updates from Joerg Roedel:
#     
#      - PASID table handling updates for the Intel VT-d driver. It implements
#        a global PASID space now so that applications usings multiple devices
#        will just have one PASID.
#     
#      - A new config option to make iommu passthroug mode the default.
#     
#      - New sysfs attribute for iommu groups to export the type of the
#        default domain.
#     
#      - A debugfs interface (for debug only) usable by IOMMU drivers to
#        export internals to user-space.
#     
#      - R-Car Gen3 SoCs support for the ipmmu-vmsa driver
#     
#      - The ARM-SMMU now aborts transactions from unknown devices and devices
#        not attached to any domain.
#     
#      - Various cleanups and smaller fixes all over the place.
