It comes from this code (mm/slab.c):
/*
 * For setting up all the kmem_list3s for cache whose buffer_size is same as
 * size of kmem_list3.
 */
static void __init set_up_list3s(struct kmem_cache *cachep, int index)
{
	int node;

	for_each_online_node(node) {
		cachep->nodelists[node] = &initkmem_list3[index + node];
		cachep->nodelists[node]->next_reap = jiffies +
		    REAPTIMEOUT_LIST3 +
		    ((unsigned long)cachep) % REAPTIMEOUT_LIST3;
	}
}

It is supposed to be used only during early init and thus marked __init.
And initkmem_list3 is marked __initdata so that matches.

But set_up_list3s() is used outside __init marked functions and thus result in an error.

I do not know how to fix this.
