  1575. kernel will support. The maximum supported value is 32 for 32-bit
  1576. kernel and 64 for 64-bit kernels; the minimum value which makes
  1577. sense is 1 for Qemu (useful only for kernel debugging purposes)
  1578. and 2 for all others.

  1650. kexec is a system call that implements the ability to shutdown your

  1652. but it is independent of the system firmware. And like a reboot
  1653. you can start any kernel with it, not just Linux.
  1654. The name comes from the similarity to the exec system call.
  1655. It is an ongoing process to be certain the hardware in a machine
  1656. is properly shutdown, so do not be surprised if this code does not
  1657. initially work for you. It may help to enable device hotplugging
