Is it ? I think it's ok to not add support for M64, hotpug etc.... for IODA1, but we can do that without *breaking* basic function that we have today. It's not completely dead, there are still a number of machines inside of IBM with P7 that we can support for a little while longer (including a few inside ozlabs). Cheers, Ben.
