KAMEZAWA Hiroyuki 36920e069a [PATCH] register_one_node() compile fix
register_one_node()'s should be defined under CONFIG_NUMA=n.
fixes following bug.

  CC	  init/version.o
  LD	  init/built-in.o
  LD	  .tmp_vmlinux1
  mm/built-in.o: In function `add_memory': undefined reference to `register_one_node'

/*
* include/linux/node.h - generic node definition
*
* This is mainly for topological representation. We define the
* basic 'struct node' here, which can be embedded in per-arch
* definitions of processors.
*
* Basic handling of the devices is done in drivers/base/node.c
* and system devices are handled in drivers/base/sys.c.
*
* Nodes are exported via driverfs in the class/node/devices/
* directory.
*
* Per-node interfaces can be implemented using a struct device_interface.
* See the following for how to do this:
* - drivers/base/intf.c
* - Documentation/driver-model/interface.txt
