Consumers of this information are the domain save/restore functions of the Xen tools. Being defined as having 3 levels the maximum supported domain size of 64 bit domains is 512 GB. The following patch expands the arch_shared_info structure to support more levels. The Xen tools are not covered in this patch as the patch series "Libxl migration v2 support": http://lists.xen.org/archives/html/xen-devel/2014-09/msg00427.html should be applied first.
