My guess is that the difference can be a lot smaller if abstracted
out properly, but that's pretty mood unless someone actually tries it :)
So yes, it's certainly not trivial (otherwise someone would have
already done it), and I didn't say you should hurry to do it. Also
note that you don't have to do it all at once, start with #including
the s390 files on s390x that are exactly the same, and after that
one file after another can be cleaned up to be s390/s390x clean.
