Subject: [PATCH 1/4] arm64/mm: drop vmemmap_pmd helpers and use generic code
Date: Sat, 4 Apr 2026 15:17:05 +0800 [thread overview]
Message-ID: <20260404071720.3577290-2-songmuchun@bytedance.com> (raw)
In-Reply-To: <20260404071720.3577290-1-songmuchun@bytedance.com>
The generic implementations now suffice; remove the arm64 copies.
