From 052e87b073cb70afcd767d32f45af2794a5a65de Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 27 May 2013 10:08:27 +0200 Subject: memory: make section size a 128-bit integer 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.
