Digging further. I notice more oddities (or maybe I've just
misunderstood this -- corrections welcomed)
(17:59:02:davej@nemesis:~)$ cat /sys/devices/system/cpu/cpu0/topology/core_id

(17:59:23:davej@nemesis:~)$ cat /sys/devices/system/cpu/cpu1/topology/core_id

(17:59:38:davej@nemesis:~)$ cat /sys/devices/system/cpu/cpu0/topology/core_siblings

Neither of these CPUs are HT / dual-core, so shouldn't these be the same ?
(18:00:04:davej@nemesis:~)$ cat /sys/devices/system/cpu/cpu0/topology/thread_siblings
00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000001

Ditto ?
