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

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