[PATCH v10 3/3] powerpc/cacheinfo: Report the correct shared_cpu_map on big-cores

From: "Gautham R. Shenoy" Currently on POWER9 SMT8 cores systems, in sysfs, we report the shared_cache_map for L1 caches (both data and instruction) to be the cpu-ids of the threads in SMT8 cores. This is incorrect since on POWER9 SMT8 cores there are two groups of threads, each of which shares
