Sorry,
Can you please change "siblings\t" to "threads\t\t". SuSE 8.1, for example,
is already doing it:
+#ifdef CONFIG_SMP
+ if (cpu_has_ht) {
+ seq_printf(m, "physical id\t: %d\n", phys_proc_id[n]);
+ seq_printf(m, "threads\t\t: %d\n", smp_num_siblings);
+ }
+#endif
Thanks,
Jun

missing this last bit, sorry..
