Interesting, I think they are internal to the 8250 drivers, as I don't
see how the number can be exported to userspace. So they should
probably be moved into 8250.c somewhere.
But I could be wrong, this code is so old it's scary, hopefully no one
really is using this number in userspace.
Only one way to find out, care to make up a patch for me to apply and
queue up for 3.10?
