This enables support for systems with more than one CPU. If you have

a system with only one CPU, say N. If you have a system with more

|
than one CPU, say Y.
|
|
|

If you say N here, the kernel will run on uni- and multiprocessor
|
|
machines, but will use only one CPU of a multiprocessor machine. If

you say Y here, the kernel will run on many, but not all,

uniprocessor machines. On a uniprocessor machine, the kernel

will run faster if you say N here.
