2296    help
2297      kexec is a system call that implements the ability to shutdown your
2298      current kernel, and to start another kernel. It is like a reboot
2299      but it is independent of the system firmware. And like a reboot
2300      you can start any kernel with it, not just Linux.
2301
2302      The name comes from the similarity to the exec system call.
2303
2304      It is an ongoing process to be certain the hardware in a machine
2305      is properly shutdown, so do not be surprised if this code does not
2306      initially work for you. It may help to enable device hotplugging
2307      support. As of this writing the exact hardware interface is
2308      strongly in flux, so no good recommendation can be made.

2315      This kernel feature is useful for number crunching applications
2316      that may need to compute untrusted bytecode during their
2317      execution. By using pipes or other transports made available to
2318      the process as file descriptors supporting the read/write
2319      syscalls, it's possible to isolate those applications in
2320      their own address space using seccomp. Once seccomp is
2321      enabled via /proc/<pid>/seccomp, it cannot be disabled
2322      and the task is only allowed to execute a few safe syscalls
2323      defined by each seccomp mode.
