When using the 8250 as a boot console and the main console results in

Set this flag for the univ8250 console to prevent double-registration.

This patch breaks console= parameter handling. Passing:
console=ttyS0 console=tty0
no longer means /dev/console is tty0 and it should be as is documented.

I'll need to find Matthew Leach's new address as he's moved jobs.
