Srikar Dronamraju f9f130ff2e powerpc/numa: Detect support for coregroup ... Add support for grouping cores based on the device-tree classification. - The last domain in the associativity domains always refers to the core. - If primary reference domain happens to be the penultimate domain in the associativity domains device-tree property, then there are no coregroups. However if its not a penultimate domain, then there are coregroups. There can be more than one coregroup. For now we would be interested in the last or the smallest coregroups, i.e one sub-group per DIE. Currently there are no firmwares that are exposing this grouping. Hence allow the basis for grouping to be abstract. Once the firmware starts using this grouping, code would be added to detect the type of grouping and adjust the sd domain flags accordingly.
