Subject: [PATCH v2 09/13] sh: drop __pXd_offset() macros that duplicate pXd_index() ones
Date: Sun, 16 Feb 2020 10:18:39 +0200 [thread overview]
Message-ID: <20200216081843.28670-10-rppt@kernel.org> (raw)
In-Reply-To: <20200216081843.28670-1-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.
