612 kexec is a system call that implements the ability to shutdown your
613 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400614 but it is independent of the system firmware. And like a reboot

662 that may need to compute untrusted bytecode during their
663 execution. By using pipes or other transports made available to
