memory: Add iommu map/unmap notifiers

Enterprise / Virtualization / QEMU - David Gibson [gibson.dropbear.id.au] - 20 June 2013 09:32 UTC

This patch adds a NotifierList to MemoryRegions which represent IOMMUs allowing other parts of the code to register interest in mappings or unmappings from the IOMMU. All IOMMU implementations will need to call memory_region_notify_iommu() to inform those waiting on the notifier list, whenever an IOMMU mapping is made or removed.
