The turbostat code only looks at thread_siblings_list to determine if processing units/threads are on the same the core. This works well on Intel systems which have a shared L1 instruction and data cache. This does not work on AMD systems which have shared L1 instruction cache but separate L1 data caches. Other utilities also check sibling's core ID to determine if the processing unit shares the same core. Additionally, the cpu_topology *cpus list used in topology_probe() can be used elsewhere in the code to simplify things. Export *cpus to the entire turbostat code, and add Processing Unit/Thread IDs information to each cpu_topology struct. Confirm that the thread is on the same core as indicated by thread_siblings_list. [v2]: Fixup CPU_* usage that caused gcc malloc error.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
