Change 85619 by millert at millert_ibook on 2005/10/20 20:40:53

	GFP_ATOMIC should really be defined as M_NOWAIT but this causes
	a panic in the zone allocator from avc_init().  Make it M_WAITOK
	for now and document the problem.  Since sebsd_malloc() didn't
	honor M_WAITOK before, this effectively changes things back to
	the way they were, but hopefully in a less confusing manner.
	We may need to investigate using a lower level allocator here.
