1170 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

Linus Torvalds1da177e2005-04-16 15:20:36 -07001906 This enables support for systems with more than one CPU. If you have
1907 a system with only one CPU, like most personal computers, say N. If
1908 you have a system with more than one CPU, say Y.
1909
1910 If you say N here, the kernel will run on single and multiprocessor
1911 machines, but will use only one CPU of a multiprocessor machine. If
1912 you say Y here, the kernel will run on many, but not all,
1913 singleprocessor machines. On a singleprocessor machine, the kernel
1914 will run faster if you say N here.
