2297    help
2298      kexec is a system call that implements the ability to shutdown your
2299      current kernel, and to start another kernel. It is like a reboot
2300      but it is independent of the system firmware. And like a reboot
2301      you can start any kernel with it, not just Linux.
2302
2303      The name comes from the similarity to the exec system call.
2304
2305      It is an ongoing process to be certain the hardware in a machine
2306      is properly shutdown, so do not be surprised if this code does not
2307      initially work for you. It may help to enable device hotplugging
2308      support. As of this writing the exact hardware interface is
2309      strongly in flux, so no good recommendation can be made.

2316      This kernel feature is useful for number crunching applications
2317      that may need to compute untrusted bytecode during their
2318      execution. By using pipes or other transports made available to
2319      the process as file descriptors supporting the read/write
2320      syscalls, it's possible to isolate those applications in
2321      their own address space using seccomp. Once seccomp is
2322      enabled via /proc/<pid>/seccomp, it cannot be disabled
2323      and the task is only allowed to execute a few safe syscalls
2324      defined by each seccomp mode.
