6ec6e0d9f2 srat, x86: add support for nodes spanning other nodes 
For example, If the physical address layout on a two node system with 8 GB
memory is something like:
node 0: 0-2GB, 4-6GB
node 1: 2-4GB, 6-8GB

Current kernels fail to boot/detect this NUMA topology.

ACPI SRAT tables can expose such a topology which needs to be supported.

3f6e5a12b8 x86: use core id bits for apicid_to_node initialization 
We shoud use core id bits instead of max cores, in case later with AMD
downcores Quad core Opteron.
