  413. kexec is a system call that implements the ability to shutdown your
  414. current kernel, and to start another kernel. It is like a reboot
  415. but it is independent of the system firmware. And like a reboot
  416. you can start any kernel with it, not just Linux.
  417. The name comes from the similarity to the exec system call.
  418. It is an ongoing process to be certain the hardware in a machine
  419. is properly shutdown, so do not be surprised if this code does not
  420. initially work for you. It may help to enable device hotplugging
  421. support. As of this writing the exact hardware interface is
  422. strongly in flux, so no good recommendation can be made.

  426. This enables support for systems with more than one CPU. If you have
  427. a system with only one CPU, like most personal computers, say N. If
  428. you have a system with more than one CPU, say Y.
  429. If you say N here, the kernel will run on single and multiprocessor
  430. machines, but will use only one CPU of a multiprocessor machine. If
  431. you say Y here, the kernel will run on many, but not all,
  432. singleprocessor machines. On a singleprocessor machine, the kernel
  433. will run faster if you say N here.
  434. People using multiprocessor machines who say Y here should also say
  435. Y to "Enhanced Real Time Clock Support", below.
