  1555. kexec is a system call that implements the ability to shutdown your
  1556. current kernel, and to start another kernel. It is like a reboot
  1557. but it is independent of the system firmware. And like a reboot
  1558. you can start any kernel with it, not just Linux.
  1559. The name comes from the similarity to the exec system call.
  1560. It is an ongoing process to be certain the hardware in a machine
  1561. is properly shutdown, so do not be surprised if this code does not
  1562. initially work for you. It may help to enable device hotplugging
  1563. support. As of this writing the exact hardware interface is
  1564. strongly in flux, so no good recommendation can be made.

  1569. help
  1570. This kernel feature is useful for number crunching applications
  1571. that may need to compute untrusted bytecode during their
  1572. execution. By using pipes or other transports made available to
  1573. the process as file descriptors supporting the read/write
  1574. syscalls, it's possible to isolate those applications in
  1575. their own address space using seccomp. Once seccomp is
  1576. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1577. and the task is only allowed to execute a few safe syscalls
  1578. defined by each seccomp mode.
  1579. If unsure, say Y. Only embedded should say N here.

  1625. The Extended Industry Standard Architecture (EISA) bus was
