Thanks for this!

There is no `From:` at the top. Since I cannot locate the patch in
Lore, did you mean to put both of you as authors perhaps? In that
case, please use a `Co-developed-by` as needed.

Perhaps it is a good idea to submit each arch independently, too.

The changes themselves look fine on a quick inspection, though the
`xmon.c` one is a global buffer (and there is another equally-sized
buffer in `xmon.c` with a hard-coded `128` constant that would be nice
to clarify).

Cheers,
Miguel
