 458           kexec is a system call that implements the ability to shutdown your
 459           current kernel, and to start another kernel.  It is like a reboot
 460           but it is indepedent of the system firmware.  And like a reboot
 461           you can start any kernel with it, not just Linux.
 462
 463           The name comes from the similiarity to the exec system call.
 464
 465           It is an ongoing process to be certain the hardware in a machine
 466           is properly shutdown, so do not be surprised if this code does not
 467           initially work for you.  It may help to enable device hotplugging
 468           support.  As of this writing the exact hardware interface is
 469           strongly in flux, so no good recommendation can be made.

 485           singleprocessor machines. On a singleprocessor machine, the kernel
 486           will run faster if you say N here.
