m68k is also handled in your patch.
um is still missing.

Thanks!
On m68k, it works on its own or combined with "[PATCH 1/2] topology:
Check for missing CPU devices."

It adds

/sys/devices/system/cpu/cpu0
|-- subsystem -> ../../../../bus/cpu
|-- topology
|   |-- core_id
|   |-- core_siblings
|   |-- core_siblings_list
|   |-- physical_package_id
|   |-- thread_siblings
|   `-- thread_siblings_list
`-- uevent

and

/sys/bus/cpu/devices/cpu0 -> ../../../devices/system/cpu/cpu0

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
