11	  in either N-Modes which allows for more nodes or M-Mode which allows
12	  for more memory.  Your hardware is almost certainly running in
13	  M-Mode, so choose M-mode here.

29	  Change the way a Linux kernel is loaded into memory on a MIPS64
30	  machine.  This is required in order to support text replication on
31	  NUMA.  If you need to understand it, read the source code.

38	  Say Y here to enable replicating the kernel text across multiple
39	  nodes in a NUMA cluster.  This trades memory for speed.
