Ok, I think I know where the issue stems from:

        definition of "package" in the AMD docs != definition of "package" in 

AMD's is "Processor: A package containing one or more Nodes." whereas
ours is:

  "Packages contain a number of cores plus shared resources, e.g. DRAM
   controller, shared caches etc."

and physical sockets we don't care about because they're not relevant to

Yeah, lemme discuss this with tglx to refresh what we were thinking then. :)

Stay tuned.
