In fact we test many different builds of Linux kernel for s390 and um with clang, and boot test them in CI.

I guess Rust only cares about s390x ("modern" 64-bit IBM) whereas I believe the Linux kernel technically builds on (32-bit) s390 despite there presumably not being many (any?) actual 20th century System/390 machines running it in practical use ?

If it ever came down to "Should we support decades old System/390 mainframes or Rust?" that seems like a no brainer but for now at least the ambition isn't anywhere close to that.
