1891 This enables support for systems with more than one CPU. If you have
1892 a system with only one CPU, like most personal computers, say N. If
1893 you have a system with more than one CPU, say Y.
1894
1895 If you say N here, the kernel will run on single and multiprocessor
1896 machines, but will use only one CPU of a multiprocessor machine. If
1897 you say Y here, the kernel will run on many, but not all,
1898 singleprocessor machines. On a singleprocessor machine, the kernel
1899 will run faster if you say N here.
1900
1901 People using multiprocessor machines who say Y here should also say
1902 Y to "Enhanced Real Time Clock Support", below.
