So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.
