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

  434. This enables support for systems with more than one CPU. If you have
  435. a system with only one CPU, like most personal computers, say N. If
  436. you have a system with more than one CPU, say Y.
  437. If you say N here, the kernel will run on single and multiprocessor
  438. machines, but will use only one CPU of a multiprocessor machine. If
  439. you say Y here, the kernel will run on many, but not all,
  440. singleprocessor machines. On a singleprocessor machine, the kernel
  441. will run faster if you say N here.
  442. People using multiprocessor machines who say Y here should also say
  443. Y to "Enhanced Real Time Clock Support", below.
