I think this also puts the existing stable and LTS trees in some interesting
state. After arch/ia64 is removed, there may be some tree-wide change
that gets backported to stable & LTS. That may break arch/ia64 in those
trees (e.g. because arguments to some common function are changed).

Maybe just deal with that if it happens ... and if anyone notices ... are there
automated builds and boot test for ia64 in those trees?
