Juergen Gross 882213990d xen: fix p2m size in dom0 for disabled memory hotplug case ... Since commit 9e2369c06c ("xen: add helpers to allocate unpopulated memory") foreign mappings are using guest physical addresses allocated via ZONE_DEVICE functionality. This will result in problems for the case of no balloon memory hotplug being configured, as the p2m list will only cover the initial memory size of the domain. Any ZONE_DEVICE allocated address will be outside the p2m range and thus a mapping can't be established with that memory address. Fix that by extending the p2m size for that case. At the same time add a check for a to be created mapping to be within the p2m limits in order to detect errors early. While changing a comment, remove some 32-bit leftovers. This is XSA-369.
