KAMEZAWA Hiroyuki 3212fe1594 [PATCH] cpu to node relationship fixup: map cpu to node
Assume that a cpu is *physically* offlined at boot time...

Because smpboot.c::smp_boot_cpu_map() canoot find cpu's sapicid,
numa.c::build_cpu_to_node_map() cannot build cpu<->node map for
offlined cpu.

For such cpus, cpu_to_node map should be fixed at cpu-hot-add.
This mapping should be done before cpu onlining.

This patch also handles cpu hotremove case.

Jack Steiner a9de983514 [IA64] Increase max node count on SN platforms
Node number are kept in the cpu_to_node_map which is
currently defined as u8. Change to u16 to accomodate
larger node numbers.

Tony Luck 8d7e35174d [IA64] fix generic/up builds
Jesse Barnes provided the original version of this patch months ago, but
other changes kept conflicting with it, so it got deferred.  Greg Edwards
dug it out of obscurity just over a week ago, and almost immediately
another conflicting patch appeared (Bob Picco's memory-less nodes).

I've resolved the conflicts and got it running again.  CONFIG_SGI_TIOCX
is set to "y" in defconfig, which causes a Tiger to not boot (oops in
tiocx_init).  But that can be resolved later ... get this in now before it
gets stale again.
