143 Cause the compiler to optimize for the PPE of the Cell Broadband
144 Engine. This will make the code run considerably faster on Cell
145 but somewhat slower on other machines. This option only changes
146 the scheduling of instructions, not the selection of instructions
147 itself, so the resulting kernel will keep running on all other
148 machines. When building a kernel that is supposed to run only
149 on Cell, you should also select the POWER4_ONLY option.

355 ---help---
356 This enables support for systems with more than one CPU. If you have
357 a system with only one CPU, say N. If you have a system with more
358 than one CPU, say Y. Note that the kernel does not currently
359 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
360 since they have inadequate hardware support for multiprocessor
361 operation.
362
363 If you say N here, the kernel will run on single and multiprocessor
364 machines, but will use only one CPU of a multiprocessor machine. If
365 you say Y here, the kernel will run on single-processor machines.
366 On a single-processor machine, the kernel will run faster if you say
367 N here.
368
369 If you don't know what to do here, say N.
