The series improves the use of hotplug memory in the Xen balloon driver. - Reliably find a non-conflicting location for the hotplugged memory (this fixes memory hotplug in a number of cases, particularly in dom0).
- Use hotplugged memory for alloc_xenballooned_pages() (keeping more memory available for the domain and reducing fragmentation of the p2m). Changes in v2: - New BP_WAIT state to signal the balloon process to wait for userspace to online the new memory. - Preallocate P2M entries in alloc_xenballooned_pages() so they do not need allocated later (in a context where GFP_KERNEL allocations are not possible).
