This series prepares cpu_to_coregroup_id() for broader use and enables coregroup support on PowerNV when firmware exposes the required associativity information.
The first patch cleans up find_primary_domain_index(). The second makes cpu_to_coregroup_id() available outside PPC_SPLPAR while preserving the existing fallback behavior. The final patch detects coregroup support from the associativity hierarchy and uses it on PowerNV systems.
