This patch three issues in NUMA API

- When 1 was passed to set_mempolicy or mbind as maxnodes argument
  get_nodes could corrupt the stack and cause a crash.  Fix that.

- Remove the restriction to do interleaving only for order 0.  Together
  with the patch that went in previously to use interleaving policy at boot
  time this should give back the original behaviour of distributing the big
  hash tables.

- Fix some bad white space in comments
