354 This enables support for systems with more than one CPU. If you have
355 a system with only one CPU, say N. If you have a system with more
356 than one CPU, say Y. Note that the kernel does not currently
357 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
358 since they have inadequate hardware support for multiprocessor
359 operation.
360
361 If you say N here, the kernel will run on single and multiprocessor
362 machines, but will use only one CPU of a multiprocessor machine. If
363 you say Y here, the kernel will run on single-processor machines.
364 On a single-processor machine, the kernel will run faster if you say
365 N here.
366
367 If you don't know what to do here, say N.
