  Question for Torbjörn: Which of the gmp machines (if any) would be
  suitable for running tests?

We do have a lot of arm64 capable systems, but they are for the period
not powered on.  I can switch them on within a couple of days.

Most systems are devboards with various cores, but then there is a an
Apple M1 running Linux and an Apple M4 running Macos.

I haven't followed these discussions so I am unaware of what hardware is
required.
