977d5f5fa2SGeert Uytterhoeven	  kexec is a system call that implements the ability to shutdown your
987d5f5fa2SGeert Uytterhoeven	  current kernel, and to start another kernel.  It is like a reboot
997d5f5fa2SGeert Uytterhoeven	  but it is independent of the system firmware.   And like a reboot
1007d5f5fa2SGeert Uytterhoeven	  you can start any kernel with it, not just Linux.
1017d5f5fa2SGeert Uytterhoeven
1027d5f5fa2SGeert Uytterhoeven	  The name comes from the similarity to the exec system call.
1037d5f5fa2SGeert Uytterhoeven
1047d5f5fa2SGeert Uytterhoeven	  It is an ongoing process to be certain the hardware in a machine
1057d5f5fa2SGeert Uytterhoeven	  is properly shutdown, so do not be surprised if this code does not
1067d5f5fa2SGeert Uytterhoeven	  initially work for you.  As of this writing the exact hardware
1077d5f5fa2SGeert Uytterhoeven	  interface is strongly in flux, so no good recommendation can be
1087d5f5fa2SGeert Uytterhoeven	  made.
