92 bool "kexec system call"
93 depends on M68KCLASSIC
94 help
95 kexec is a system call that implements the ability to shutdown your
96 current kernel, and to start another kernel. It is like a reboot
97 but it is independent of the system firmware. And like a reboot
98 you can start any kernel with it, not just Linux.
99
100 The name comes from the similarity to the exec system call.
101
102 It is an ongoing process to be certain the hardware in a machine
103 is properly shutdown, so do not be surprised if this code does not
104 initially work for you. As of this writing the exact hardware
105 interface is strongly in flux, so no good recommendation can be
106 made.
