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

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