542 | This adds the cpufreq driver for SuperH. Any CPU that supports |
543 | clock rate rounding through the clock framework can use this | |
544 | driver. While it will make the kernel slightly larger, this is | |

567 | kexec is a system call that implements the ability to shutdown your |

cad82448 PM |
570 | you can start any kernel with it, not just Linux. |
