   9           The nodes of Origin, Onyx, Fuel and Tezro systems can be configured
  10           in either N-Modes which allows for more nodes or M-Mode which allows
  11           for more memory.  Your hardware is almost certainly running in
  12           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.
