Subject: [PATCH 04/12] csky: replace definitions of __pXd_offset() with pXd_index()
Date: Tue, 12 May 2020 21:44:14 +0300	[thread overview]
Message-ID: <20200512184422.12418-5-rppt@kernel.org> (raw)
In-Reply-To: <20200512184422.12418-1-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.
