249 all sorts of stuff like CONFIG_MEMORY_START because the config
250 system doesn't already know what it is. You get a machine vector

437 Select this option if you want to disable continuous timer ticks
438 and have them programmed to occur as required. This option saves
439 power as the system can remain in idle state for longer.
440
441 By default dynamic tick is disabled during the boot, and can be
442 manually enabled with:
443
444 echo 1 > /sys/devices/system/timer/timer0/dyn_tick
445
446 Alternatively, if you want dynamic tick automatically enabled
447 during boot, pass "dyntick=enable" via the kernel command string.

522 kexec is a system call that implements the ability to shutdown your
523 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400524 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800525 you can start any kernel with it, not just Linux.
526
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400527 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800528
529 It is an ongoing process to be certain the hardware in a machine
530 is properly shutdown, so do not be surprised if this code does not
531 initially work for you. It may help to enable device hotplugging
532 support. As of this writing the exact hardware interface is
533 strongly in flux, so no good recommendation can be made.
