CORRECTION FOR APAR MA47420 :
-----------------------------
Licensed Internal Code has been changed to provide support for
reducing machine gating and seize contention on libraries in
Materialize Pointer (MATPTR) and Materialize System Object
(MATSOBJ) MI instructions. This fix does not reduce the
contention, it adds framework for use by future fixes to reduce
the contention.
