Unfortunately, I don't have access to ia64 hardware anymore, so I am
not able to verify that this works on hardware.  I would expect that
the patches work, and would recommend that you make the changes, and
then we can back them out later if someone runs into a problem.  It
just looks like an oversight due to lack of ia64 maintenance that this
wasn't done before.

The ia64 changes are OK.
