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