Subject: [PATCH v2 4/5] loongarch/mm: drop vmemmap_check_pmd helper and use generic code
Date: Sat, 4 Apr 2026 20:20:57 +0800 [thread overview]
Message-ID: <20260404122105.3989557-5-songmuchun@bytedance.com> (raw)
In-Reply-To: <20260404122105.3989557-1-songmuchun@bytedance.com>
The generic implementations now suffice; remove the loongarch copies.
