  1589. kexec is a system call that implements the ability to shutdown your
  1590. current kernel, and to start another kernel. It is like a reboot
  1591. but it is independent of the system firmware. And like a reboot
  1592. you can start any kernel with it, not just Linux.
  1593. The name comes from the similarity to the exec system call.
  1594. It is an ongoing process to be certain the hardware in a machine
  1595. is properly shutdown, so do not be surprised if this code does not
  1596. initially work for you. It may help to enable device hotplugging
  1597. support. As of this writing the exact hardware interface is

  1604. This kernel feature is useful for number crunching applications

  1606. execution. By using pipes or other transports made available to
  1607. the process as file descriptors supporting the read/write
  1608. syscalls, it's possible to isolate those applications in
  1609. their own address space using seccomp. Once seccomp is
  1610. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1611. and the task is only allowed to execute a few safe syscalls
