[PATCH 22/80] serial: Make uart_port's ioport "unsigned long".
From: Alan Cox
Date: Mon Oct 13 2008 - 05:40:44 EST
From: David Miller <davem@xxxxxxxxxxxxx>
Otherwise the top 32-bits of the resource value get chopped
off on 64-bit systems, and the resulting I/O accesses go to
random places.
Thanks to testing and debugging by Josip Rodin, which helped
track this down.
