Bah, in carefully removing all the "let's send it as a reply to the
previous thread" command line flags, I cleverly also skipped adding a
cover letter, so this updated series got sent out without one.

I need more coffee.

But hey, it's not like the people cc'd haven't seen it before, and if
you want to see *all* the patches (I didn't want to patch-bomb people
with the prep-work), at least 'b4' is happy so you can get it all with
just

   b4 am 20221109203051.1835763-1-torvalds@linux-foundation.org

this time.

The main changes to the previously posted series are

 (a) try to  move the s390 changes to generic code

 (b) build-time checking for the value range of the flags passed to
encode_page()

 (c) added comments both to code and commit messages

I'm sure I messed something up in the process, not just the lack of
cover letter which has now turned into this "tail letter" instead.
