Change 96795 by jb@jb_freebsd2 on 2006/05/07 22:15:40

	Add the hook for the cyclic timer subsystem. The cyclic subsystem
	code which uses this is enabled using the CYCLIC kernel option.
	It's an option because the code is covered by Sun's CDDL. DTrace
	requires the cyclic subsystem to get high priority probes via
	an interrupt.
