  1542. This allows you to specify the maximum number of CPUs which this
  1543. kernel will support. The maximum supported value is 32 for 32-bit
  1544. kernel and 64 for 64-bit kernels; the minimum value which makes
  1545. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1546. and 2 for all others.
  1547. This is purely to save memory - each supported CPU adds
  1548. approximately eight kilobytes to the kernel image. For best
  1549. performance should round up your number of processors to the next
  1550. power of two.
