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

in either N-Modes which allows for more nodes or M-Mode which allows

for more memory. Your hardware is almost certainly running in

M-Mode, so choose M-mode here.

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

Say Y here to enable replicating the kernel text across multiple
