   Set size cell value to 2 for 4GB memory support in katmai. Also set PCI-E
   node inbound DMA ranges size to 4GB for correct boot up of katmai.

This conflicts with one I already have queued up in my next branch.  It also
seems to lack some of the changes that patch has.

Stefan, can you look this over and work out with Pravin what to do?

As Josh already mentioned, I already submitted a patch which partly covers 
this 4GB support:

http://patchwork.ozlabs.org/patch/36768/

I suggest that you rebase your patch (only with the DMA ranges stuff) and 
resend it.

Cheers,
Stefan
