1894 This enables support for systems with more than one CPU. If you have
1895 a system with only one CPU, like most personal computers, say N. If
1896 you have a system with more than one CPU, say Y.
1897
1898 If you say N here, the kernel will run on single and multiprocessor
1899 machines, but will use only one CPU of a multiprocessor machine. If
1900 you say Y here, the kernel will run on many, but not all,
1901 singleprocessor machines. On a singleprocessor machine, the kernel
1902 will run faster if you say N here.
1903
1904 People using multiprocessor machines who say Y here should also say
1905 Y to "Enhanced Real Time Clock Support", below.
