Linux Operating System Source Code: IBM Patches

We need some way to replicate the e820 tables for kexec.  This 
modifies struct resource to use u64's for its start and end fields. 
This way we can export the whole e820 table on PAE machines.

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:
