The quilt patch titled
     Subject: mm/page_alloc: don't build vm_numa_stat_key if CONFIG_NUMA=n
has been removed from the -mm tree.  Its filename was
     mm-page_alloc-dont-build-vm_numa_stat_key-if-config_numa=n.patch

This patch was dropped because it was merged into the mm-stable branch

vm_numa_stat_key is only exported if CONFIG_NUMA is set, so avoid the
following warning by guarding it in an #ifdef on CONFIG_NUMA:

mm/page_alloc.c:165:1: warning: symbol 'vm_numa_stat_key' was not declared. Should it be static?
