Linus, please apply.
This has been discussed in a previous thread originated by David
Mosberger. This removed early_serial_setup() in favor of a
working early_port_register() call. Many PPC systems rely on
this functionality and are currently hacking around it in the
PPC devel tree. Last I looked, IA64 still had this in their
devel tree too.
