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. | |

28 | Change the way a Linux kernel is loaded into memory on a MIPS64 | |
e73ea273 | 29 | machine. This is required in order to support text replication on |
ae6aafe3 RB |
30 | NUMA. If you need to understand it, read the source code. |
