  1596. kexec is a system call that implements the ability to shutdown your
  1597. current kernel, and to start another kernel. It is like a reboot
  1598. but it is independent of the system firmware. And like a reboot
  1599. you can start any kernel with it, not just Linux.

  1611. This kernel feature is useful for number crunching applications

  1614. the process as file descriptors supporting the read/write

  1616. their own address space using seccomp. Once seccomp is
  1617. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1618. and the task is only allowed to execute a few safe syscalls
