Change 131199 by jb at jb_freebsd1 on 2007/12/19 03:07:20

	Let's keep all the DTrace hook definitions in one file: dtrace_bsd.h
	These *MUST* be BSD licensed to keep CDDL code quarantined.
	
	Even so, the KDTRACE_HOOKS option lets embedded developers ignore
	all things DTrace related. I just hope that _everyone_ will have
	KDTRACE_HOOKS defined.
