Subject: [PATCH 0/6] Introduce ID_PFR2 and other CPU feature changes

This series is primarily motivated from an adhoc list from Mark Rutland
during our ID_ISAR6 discussion [1]. Besides, it also includes a patch
which does macro replacement for various open bits shift encodings in
various CPU ID registers. This series is based on linux-next 20200124.

Is there anything else apart from these changes which can be accommodated
in this series, please do let me know. Thank you.
