Here's take one of the 64-bit resources.  resource->flags seems to be 
used often to mask out things in resource->start/end, so I think it 
needs to be u64 too.  But, Is it all right to let things like 
pcibios_update_resource() truncate the resource addresses like they do?

With my config, it has no more warnings than it did before.

Here's /proc/iomem from a 16-gig ia32 box with the patch:
