10 The nodes of Origin, Onyx, Fuel and Tezro systems can be configured
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.
