[PATCH] i386 sparsemem: undefined early_pfn_to_nid when !NUMA

[Dave Hansen <haveblue@us.ibm.com>]

On i386, early_pfn_to_nid() is only defined when discontig.c
is compiled in.  The current dependency doesn't reflect this,
probably because the default i386 config doesn't allow for
SPARSEMEM without NUMA.

But, we'll need SPARSEMEM && !NUMA for memory hotplug, and I
do this for testing anyway.

Andy, please forward on if you concur.
