--- Comment #4 from Juha Lepola <fluxie at kapsi.fi> ---
I think I know what the problem is. The command "cat
/sys/devices/system/cpu/cpu0/topology/thread_siblings" reports two different
siblings masks separated with a comma on my machine: "00000000,00010001".

The implementation in the function "create_logical_proc_info" seems to parse
only the first mask. Because the first mask is only zeros the number of logical
CPUs will be zero on my machine. I have ThreadRipper 1950X.

Parsing the siblings from
"/sys/devices/system/cpu/cpu0/topology/thread_siblings_list" would be more
straightforward if more inefficient. But on the other hand, if we used
"thread_siblings_list" to create the "thread_mask" mask in
"create_logical_proc_info" then we wouldn't have to read "thread_siblings" at
all.

I can write a patch but I would like to know if it was acceptable to use
"thread_siblings_list" instead of "thread_siblings"?
