120 This enables support for systems with more than one CPU. If
121 you say N here, the kernel will run on single and
122 multiprocessor machines, but will use only one CPU of a
123 multiprocessor machine. If you say Y here, the kernel will run
124 on many, but not all, single processor machines. On a single
125 processor machine, the kernel will run faster if you say N
