  94           kexec is a system call that implements the ability to shutdown your
  95           current kernel, and to start another kernel.  It is like a reboot
  96           but it is independent of the system firmware.   And like a reboot
  97           you can start any kernel with it, not just Linux.
  98
  99           The name comes from the similarity to the exec system call.
 100
 101           It is an ongoing process to be certain the hardware in a machine
 102           is properly shutdown, so do not be surprised if this code does not
 103           initially work for you.  As of this writing the exact hardware
 104           interface is strongly in flux, so no good recommendation can be
 105           made.
