+Description: /sys/kernel/iommu_groups/reserved_regions list IOVA
+ regions that are reserved. Not necessarily all
+ reserved regions are listed. This is typically used to
+ output direct-mapped, MSI, non mappable regions. Each
+ region is described on a single line: the 1st field is
+ the base IOVA, the second is the end IOVA and the third
+ field describes the type of the region.
