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

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

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