This partially reverts commit 882213990d32fd224340a4533f6318dd152be4b2.There's no need to special case XEN_UNPOPULATED_ALLOC anymore in order to correctly size the p2m. The generic memory hotplug option has already been tied together with the Xen hotplug limit, so enabling memory hotplug should already trigger a properly sized p2m on Xen PV.
Can you add some words here that XEN_UNPOPULATED_ALLOC depends on MEMORY_HOTPLUG via ZONE_DEVICE? Juergen
