 557           clock rate rounding through the clock framework can use this

 559           harmless for CPUs that don't support rate rounding. The driver

 581           kexec is a system call that implements the ability to shutdown your
 582           current kernel, and to start another kernel.  It is like a reboot
 583           but it is independent of the system firmware.  And like a reboot
 584           you can start any kernel with it, not just Linux.
 585
 586           The name comes from the similarity to the exec system call.
