Subject: [PATCH v2 04/12] csky: replace definitions of __pXd_offset() with pXd_index()
Date: Thu, 14 May 2020 20:03:19 +0300	[thread overview]
Message-ID: <20200514170327.31389-5-rppt@kernel.org> (raw)
In-Reply-To: <20200514170327.31389-1-rppt@kernel.org>

From: Mike Rapoport <rppt@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.
