  1561. kexec is a system call that implements the ability to shutdown your
  1562. current kernel, and to start another kernel. It is like a reboot
  1563. but it is independent of the system firmware. And like a reboot
  1564. you can start any kernel with it, not just Linux.
  1565. The name comes from the similarity to the exec system call.
  1566. It is an ongoing process to be certain the hardware in a machine
  1567. is properly shutdown, so do not be surprised if this code does not
  1568. initially work for you. It may help to enable device hotplugging
  1569. support. As of this writing the exact hardware interface is
  1570. strongly in flux, so no good recommendation can be made.

  1575. help
  1576. This kernel feature is useful for number crunching applications
  1577. that may need to compute untrusted bytecode during their
  1578. execution. By using pipes or other transports made available to
  1579. the process as file descriptors supporting the read/write
  1580. syscalls, it's possible to isolate those applications in
  1581. their own address space using seccomp. Once seccomp is
  1582. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1583. and the task is only allowed to execute a few safe syscalls
  1584. defined by each seccomp mode.
  1585. If unsure, say Y. Only embedded should say N here.

  1627. The Extended Industry Standard Architecture (EISA) bus was
  1628. developed as an open alternative to the IBM MicroChannel bus.
  1629. The EISA bus provided some of the features of the IBM MicroChannel
  1630. bus while maintaining backward compatibility with cards made for
  1631. the older ISA bus. The EISA bus saw limited use between 1988 and
  1632. 1995 when it was made obsolete by the PCI bus.
