 | |
| 	  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
