I would keep it at least in this upcoming release. I also wonder if anybody
tests IA-64 with new LTP, i.e. how long we should keep it in LTP before
removing.

BTW I removed some IA-64 some years ago during some test rewrite (too long ago
now to search for it). At the time I was not aware that anybody would test IA-64
with LTP.

Kind regards,
Petr
