I see.  I either missed this requirement when I implemented those bits for CRIS
or it wasn't a requirement at the time.  BTW, I see several ports are missing
those calls.  I guess in the general case it can't be left to middle-end to
call those functions at the right time, so I'll just update the port and
hopefully the documentation, but no promises.  Assigning the PR to myself while
verifying that this is the cause.
