st.c usees alloc_pages(). include/linux/gfp.h:

#define alloc_pages(gfp_mask, order) \
                alloc_pages_node(numa_node_id(), gfp_mask, order)

And in include/linux/mmzone.h:

#define numa_node_id()          (cpu_to_node(smp_processor_id()))

And asm-i386/topology.h has:

static inline int cpu_to_node(int cpu)
{
        return cpu_2_node[cpu];
}

Also, here is my .config, maybe CONFIG_X86_NUMAQ must also be set to hit it?
