Change 109194 by jb at jb_freebsd8 on 2006/11/04 02:02:01

	Give all arches kernel support for loading DTrace modules
	by default. This causes the DTrace kernel hooks to be
	compiled in, plus some functions named with the dtrace_
	prefix to help DTrace's FBT (function boundary trace)
	provider know that it can't trace them because they are
	called from the DTrace probe context.
