From: Len Brown <len.br...@intel.com> Create CPU topology sysfs attributes: "core_threads" and "core_threads_list"
These attributes represent all of the logical CPU threads that share the same core. These attriutes is synonymous with the existing "thread_siblings" and "thread_siblings_list" attribute, which will be deprecated.
