David Rientjes f957db4fcd mm, hotplug: protect zonelist building with zonelists_mutex
Commit 959ecc48fc75 ("mm/memory_hotplug.c: fix building of node hotplug
zonelist") does not protect the build_all_zonelists() call with
zonelists_mutex as needed.  This can lead to races in constructing
zonelist ordering if a concurrent build is underway.  Protecting this
with lock_memory_hotplug() is insufficient since zonelists can be
rebuild though sysfs as well.
