241 all sorts of stuff like CONFIG_MEMORY_START because the config
242 system doesn't already know what it is. You get a machine vector

491 kexec is a system call that implements the ability to shutdown your
492 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400493 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800494 you can start any kernel with it, not just Linux.
495
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400496 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800497
498 It is an ongoing process to be certain the hardware in a machine
499 is properly shutdown, so do not be surprised if this code does not
500 initially work for you. It may help to enable device hotplugging
501 support. As of this writing the exact hardware interface is
502 strongly in flux, so no good recommendation can be made.
