It would be a bit neater to have a helper function to perform the call,
rather than directly accessing the notifier list. Apart from anything
else, this hides the fact that the core code (presently!) uses the
blocking_ style notifiers.
Introduced kernel_restart_notify (proposals for better names welcome).
As a side effect, moved restart_notifier_list into kernel/reboot.c and
made it static.
Thanks,
Guenter
