Fix build error for numa_clear_node() under IA64
numa_clear_node() function is not implemented under IA64, it will be called in unmap_cpu_on_node() in mm/memory_hotplug.c. This cause build error under IA64, this patch adds numa_clear_node() in IA64 to fix this problem. [Added __cpuinit notation to numa_clear_node() to keep linker happy -Tony] Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
