78 bool "MMU-based Paged Memory Management Support"

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