  1587. kexec is a system call that implements the ability to shutdown your
  1588. current kernel, and to start another kernel. It is like a reboot
  1589. but it is independent of the system firmware. And like a reboot
  1590. you can start any kernel with it, not just Linux.
  1591. The name comes from the similarity to the exec system call.
  1592. It is an ongoing process to be certain the hardware in a machine
  1593. is properly shutdown, so do not be surprised if this code does not
  1594. initially work for you. It may help to enable device hotplugging
  1595. support. As of this writing the exact hardware interface is

  1602. This kernel feature is useful for number crunching applications

  1605. the process as file descriptors supporting the read/write
  1606. syscalls, it's possible to isolate those applications in
  1607. their own address space using seccomp. Once seccomp is
  1608. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1609. and the task is only allowed to execute a few safe syscalls
