[PATCH] cpu to node relationship fixup: acpi_map_cpu2node
Problem description: We have additional_cpus= option for allocating possible_cpus. But nid for possible cpus are not fixed at boot time. cpus which is offlined at boot or cpus which is not on SRAT is not tied to its node. This will cause panic at cpu onlining. Usually, pxm_to_nid() mapping is fixed at boot time by SRAT. But, unfortunately, some system (my system!) do not include full SRAT table for possible cpus. (Then, I use additiona_cpus= option.) For such possible cpus, pxm<->nid should be fixed at hot-add. We now have acpi_map_pxm_to_node() which is also used at boot. It's suitable here.
