  1129. This enables support for systems with more than one CPU. If you have
  1130. a system with only one CPU, like most personal computers, say N. If
  1131. you have a system with more than one CPU, say Y.
  1132. If you say N here, the kernel will run on single and multiprocessor
  1133. machines, but will use only one CPU of a multiprocessor machine. If
  1134. you say Y here, the kernel will run on many, but not all,
  1135. singleprocessor machines. On a singleprocessor machine, the kernel
  1136. will run faster if you say N here.
  1137. People using multiprocessor machines who say Y here should also say
  1138. Y to "Enhanced Real Time Clock Support", below.

  1150. kernel will support. The maximum supported value is 32 for 32-bit
  1151. kernel and 64 for 64-bit kernels; the minimum value which makes

  1158. This option reduces the latency of the kernel when reacting to

  1160. be preempted even if it is in kernel mode executing a system call.
