If I apply the following patch and boot with it on x86-64, dom0 boot
hangs in random places. I found it while adding full ioremap
support. I suspect an overflow in the console subsystem due to ioremap
being called before the console is fuly set up, but did not have time
to fully investigate yet. If anyone wants to take a stab at fixing
this, please do :-)
Cheers,
Muli
