* srat, x86: add support for nodes spanning other nodesSuresh Siddha2008-04-191-1/+1
| | | | | | | | | | | | | | | 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.

* x86: use core id bits for apicid_to_node initializationYinghai Lu2008-01-301-7/+10
| | | | | | | | | | | | | | | We shoud use core id bits instead of max cores, in case later with AMD downcores Quad core Opteron.
