Just to amplify: put the declaration of the data types needed for
your generic instantiation, together with the generic instantiation
itself, in a package specification:

   package X is
     type Y is ...;
     package Z is new Linked_Lists(Y);
   end X;

Now say "with X; use X;" at the start of your test program instead
of "with Linked_Lists".
