2.6.0-test3: #undef SMP && #define NUMA does not compile

2.6.0-test3: #undef SMP && #define NUMA does not compile

[Andreas Schwab]

When configuring 2.6.0-test3 with CONFIG_SMP disabled and CONFIG_NUMA
enabled I get undefined references to cpu_to_node_map and
node_to_cpu_mask.  Both variables are defined in
arch/ia64/kernel/smpboot.c, thus only available for SMP.

Surely we should make NUMA depend on SMP?  Or does someone have an
example of a NUMA single-processor box ;-)

One might want to boot an UP kernel on a NUMA box, would that still work?

I don't see why it shouldn't ... if it doesn't, I'd say that's a bug.
