KEXEC — kexec system call (experimental)


kexec is a system call that implements the ability to shut down your current kernel and start up another. It is like a reboot, but is indepedent of the system firmware. And like a reboot, you can start any kernel with it, not just Linux.

The name comes from the similiarity to the exec system call.

Do not be surprised if this code does not initially work for you. It may help to enable device hotplugging support. As of this writing, the exact hardware interface is strongly in flux, so no good recommendation can be made.
