These #defines are not used anywhere.
They are used in topology.c driver and sched.c
+#define mc_capable() (cpu_topology[0].socket_id != -1) +#define smt_capable() (cpu_topology[0].thread_id != -1)
Neither are these.
They are used in sched.c
Ahh, sorry for the noise. Documentation/cputopology.txt is most illuminating.
