  	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

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