I am not sure what is being asked. Is this it?

The change will be made to mbbiRecord, mbbiDirectRecord, mbboRecord, and
mbboDirectRecord.

For each, SPC_NOMOD will no longer be specified for SHFT.

For all existing mbbi, mbbo, mbbiDirect, mbboDirect device support in
base statements like the following

 pmbbo->shft = pvmeio->signal;

will be changed to

  if(pmbbo->shft==0) pmbbo->shft = pvmeio->signal;

1) Do we really want to do the later?
2) What about all the support not in base?
3) Where will this be documented?

This also does not seem to address Bob Dalesio's concern about what
happens when links are modified dynamically.

For bi, bo records signal is used to select bit in register. For
mbbi,mbbi it was used to select low order bit in register. Do we really
want to change this convention?
