1920 This enables support for systems with more than one CPU. If you have
1921 a system with only one CPU, like most personal computers, say N. If
1922 you have a system with more than one CPU, say Y.
1923
1924 If you say N here, the kernel will run on single and multiprocessor
1925 machines, but will use only one CPU of a multiprocessor machine. If
1926 you say Y here, the kernel will run on many, but not all,
1927 singleprocessor machines. On a singleprocessor machine, the kernel
1928 will run faster if you say N here.
