105 help
106 kexec is a system call that implements the ability to shutdown your
107 current kernel, and to start another kernel. It is like a reboot
108 but it is independent of the system firmware. And like a reboot
109 you can start any kernel with it, not just Linux.
110
111 The name comes from the similarity to the exec system call.
112
113 It is an ongoing process to be certain the hardware in a machine
114 is properly shutdown, so do not be surprised if this code does not
115 initially work for you. As of this writing the exact hardware
116 interface is strongly in flux, so no good recommendation can be
117 made.

123 Say Y to export the bootinfo used to boot the kernel in a
124 "bootinfo" file in procfs. This is useful with kexec.
