+               When CONFIG_NUMA is enabled, a symbolic link that points
+               to the corresponding NUMA node directory.
+
+               For example, the following symlink is created for cpu42
+               in NUMA node 2:
+
+               /sys/devices/system/cpu/cpu42/node2 -> ../../node/node2
