From: Dave Chinner <dchinner@xxxxxxxxxx>
CHANGE:
o Add description of new members in opt_params struct.
o Drop "const" from struct opt_params - a previous patch was changed to
not create it as const.
Add flags to the generic input parameter tables so that
respecification can be detected in a generic manner.
