ia64 is the only architecture defining it, nobody uses it in the kernel.
If the ia64 maintainers want to remove it in a separate patch, that
would probably be a good idea.

I tried not to change the ABI in any way in my patch, and there is
a theoretical possibility that some user space program on ia64 currently
depends on that definition.
