Subject: [PATCH 4/4] sparc/mm: drop vmemmap_check_pmd helper and use generic code
Date: Sat, 4 Apr 2026 15:17:12 +0800 [thread overview]
Message-ID: <20260404071720.3577290-9-songmuchun@bytedance.com> (raw)
In-Reply-To: <20260404071720.3577290-1-songmuchun@bytedance.com>
The generic implementations now suffice; remove the sparc copies.
