There are a lot of places where _make_foo_list()s are implemented. Actually base.obj_make_list() can be used to make the list. The patch is to clean up the redundancies and make the code clean. Also, in order to make _from_db_objects()s the same format, we add 'context' into the parameter list in instance fault object. Related to blueprint icehouse-objects.
