  1614. kexec is a system call that implements the ability to shutdown your
  1615. current kernel, and to start another kernel. It is like a reboot
  1616. but it is independent of the system firmware. And like a reboot
  1617. you can start any kernel with it, not just Linux.
  1618. The name comes from the similarity to the exec system call.
  1619. It is an ongoing process to be certain the hardware in a machine
  1620. is properly shutdown, so do not be surprised if this code does not
  1621. initially work for you. It may help to enable device hotplugging

  1629. This kernel feature is useful for number crunching applications
  1630. that may need to compute untrusted bytecode during their
  1631. execution. By using pipes or other transports made available to
  1632. the process as file descriptors supporting the read/write
  1633. syscalls, it's possible to isolate those applications in
  1634. their own address space using seccomp. Once seccomp is
  1635. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1636. and the task is only allowed to execute a few safe syscalls
  1637. defined by each seccomp mode.
