mm/slab.c
  2117                  kmem_freepages(cachep, addr, *this_cpu);
  2118                  if (OFF_SLAB(cachep)) {
  2119                          if (this_cpu)

	We already dereferenced "this_cpu" two lines earlier. 

  2120                                  __cache_free(cachep->slabp_cache, slabp, this_cpu);
  2121                          else
  2122                                  kmem_cache_free(cachep->slabp_cache, slabp);
