893 byte order. These modes require different kernels. Say Y if your

1081 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1340 This enables support for systems with more than one CPU. If you have
1341 a system with only one CPU, like most personal computers, say N. If
1342 you have a system with more than one CPU, say Y.

1344 If you say N here, the kernel will run on single and multiprocessor
1345 machines, but will use only one CPU of a multiprocessor machine. If
1346 you say Y here, the kernel will run on many, but not all,
1347 singleprocessor machines. On a singleprocessor machine, the kernel
1348 will run faster if you say N here.
