2.5.64-mm8: link error with CONFIG_NUMA and !CONFIG_SMP

I get many errors at the final linking when compiling a kernel with
CONFIG_NUMA enabled but CONFIG_SMP disabled:

<-- snip -->

...
/home/bunk/linux/kernel-2.5/linux-2.5.64-mm8/include/asm/topology.h:41:
undefined reference to `cpu_2_node'
...

<-- snip -->

the problem is that include/asm-i386/topology.h says:

<-- snip -->

...
#ifdef CONFIG_NUMA
...
extern volatile int cpu_2_node[];
...

<-- snip -->

but cpu_2_node is in arch/i386/kernel/smpboot.c that only gets included
with CONFIG_SMP.
