1892 This enables support for systems with more than one CPU. If you have
1893 a system with only one CPU, like most personal computers, say N. If
1894 you have a system with more than one CPU, say Y.
1895
1896 If you say N here, the kernel will run on single and multiprocessor
1897 machines, but will use only one CPU of a multiprocessor machine. If
1898 you say Y here, the kernel will run on many, but not all,
1899 singleprocessor machines. On a singleprocessor machine, the kernel
1900 will run faster if you say N here.
1901
1902 People using multiprocessor machines who say Y here should also say
1903 Y to "Enhanced Real Time Clock Support", below.
