Subject: [PATCH RFC v3 16/21] openrisc/pgtable: drop __pmd_offset()
Date: Wed, 02 Sep 2026 12:56:18 +0100 [thread overview]
Message-ID: <20260902-dummy_ptxp3-v3-16-5d8f5b17c25c@arm.com> (raw)
In-Reply-To: <20260902-dummy_ptxp3-v3-0-5d8f5b17c25c@arm.com>
From: "David Hildenbrand (Arm)" <david@kernel.org>
The macro is unused, and will collide with a folded page table helper.
Let's just remove it.
Signed-off-by: David Hildenbrand (Arm) <david@kernel.org>
