[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.
