87 support by paged memory management. If unsure, say 'Y'.

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