  	  kexec is a system call that implements the ability to shutdown your

  	  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.  It may help to enable device hotplugging
  	  support.  As of this writing the exact hardware interface is

  	  This kernel feature is useful for number crunching applications

  	  the process as file descriptors supporting the read/write
  	  syscalls, it's possible to isolate those applications in
  	  their own address space using seccomp. Once seccomp is

  	  If you say N here, the kernel will run on single and multiprocessor
