This patch fixes the following build breakage when memory hotplug is enabled on
UMA configurations:

  /home/test/linux-2.6/mm/slub.c: In function 'kmem_cache_init':
  /home/test/linux-2.6/mm/slub.c:3031:2: error: 'slab_memory_callback'
  undeclared (first use in this function)
  /home/test/linux-2.6/mm/slub.c:3031:2: note: each undeclared
  identifier is reported only once for each function it appears in
  make[2]: *** [mm/slub.o] Error 1
