Subject: [PATCH v4 10/14] sh: drop __pXd_offset() macros that duplicate pXd_index() ones
Date: Tue, 14 Apr 2020 18:34:51 +0300	[thread overview]
Message-ID: <20200414153455.21744-11-rppt@kernel.org> (raw)
In-Reply-To: <20200414153455.21744-1-rppt@kernel.org>

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

The __pXd_offset() macros are identical to the pXd_index() macros and there
is no point to keep both of them. All architectures define and use
pXd_index() so let's keep only those to make mips consistent with the rest
of the kernel.
