  12          This option enables a tickless system: timer interrupts will
  13          only trigger on an as-needed basis both when the system is
  14          busy and when the system is idle.

  20        help
  21          This option enables high resolution timer support. If your
  22          hardware is not capable then this option only increases
  23          the size of the kernel image.
