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