[MIPS] Add support for kexec
A tiny userland application loading the kernel and invoking kexec_load for mips is available here: http://chac.le-poulpe.net/~nico/kexec/kexec-2006-10-18.tar.gz Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

770 bool "Kexec system call (EXPERIMENTAL)"
771 depends on EXPERIMENTAL
772 help
773 kexec is a system call that implements the ability to shutdown your
774 current kernel, and to start another kernel. It is like a reboot
775 but it is indepedent of the system firmware. And like a reboot
776 you can start any kernel with it, not just Linux.
777
778 The name comes from the similiarity to the exec system call.
779
780 It is an ongoing process to be certain the hardware in a machine
781 is properly shutdown, so do not be surprised if this code does not
782 initially work for you. It may help to enable device hotplugging
783 support. As of this writing the exact hardware interface is
784 strongly in flux, so no good recommendation can be made.
