[PATCH v2 04/12] csky: replace definitions of __pXd_offset() with pXd_index()

Mike Rapoport rppt at kernel.org
Fri May 15 03:03:19 AEST 2020


From: Mike Rapoport <rppt at linux.ibm.com>

All architectures use pXd_index() to get an entry in the page table page
corresponding to a virtual address.

Align csky with other architectures.
