mm: add numa node symlink for cpu devices in sysfs
You can discover which CPUs belong to a NUMA node by examining
/sys/devices/system/node/node#/
However, it's not convenient to go in the other direction, when looking at
/sys/devices/system/cpu/cpu#/
Yes, you can muck about in sysfs, but adding these symlinks makes life a
lot more convenient.
