	help
	  kexec is a system call that implements the ability to shutdown your
	  current kernel, and to start another kernel.  It is like a reboot
	  but it is independent of the system firmware.   And like a reboot
	  you can start any kernel with it, not just Linux.

	  The name comes from the similarity to the exec system call.

	  It is an ongoing process to be certain the hardware in a machine
	  is properly shutdown, so do not be surprised if this code does not
	  initially work for you.  As of this writing the exact hardware
	  interface is strongly in flux, so no good recommendation can be
	  made.

config BOOTINFO_PROC
	bool "Export bootinfo in procfs"
	depends on KEXEC && M68KCLASSIC
	help
	  Say Y to export the bootinfo used to boot the kernel in a
	  "bootinfo" file in procfs.  This is useful with kexec.
