94 bool "kexec system call"
95 depends on M68KCLASSIC
98 kexec is a system call that implements the ability to shutdown your
99 current kernel, and to start another kernel. It is like a reboot
100 but it is independent of the system firmware. And like a reboot
101 you can start any kernel with it, not just Linux.
103 The name comes from the similarity to the exec system call.
105 It is an ongoing process to be certain the hardware in a machine
106 is properly shutdown, so do not be surprised if this code does not
107 initially work for you. As of this writing the exact hardware
108 interface is strongly in flux, so no good recommendation can be
112 bool "Export bootinfo in procfs"
113 depends on KEXEC && M68KCLASSIC
115 Say Y to export the bootinfo used to boot the kernel in a
116 "bootinfo" file in procfs. This is useful with kexec.
