[PATCH] discontig patch (still ugly)

Ok, here's a new patch that addresses the problems below, just for
reference.  I'll split out the contig.c stuff and send that seperately
in a minute.

I had just removed that printk at Xavier's request and missed that it
wasn't being used anymore.  Fixed.

No, because that was necessary for the contig.c/discontig.c seperation.
Which header file would be better?

You mean for the discontig case?  mem_map isn't there.  It only exists
(mm/memory.c) if CONFIG_DISCONTIGMEM is off, otherwise we just use
vmem_map and pgdata_t->node_mem_map for everything.

Right now (and even without this patch) the config options are kind of a
mess.  CONFIG_DISCONTIGMEM doesn't make sense without CONFIG_NUMA and
CONFIG_VIRTUAL_MEMMAP even though they should all be independent.  I'll
try to clean that up too.
