Subject: [PATCH -next v6 4/6] mm: remove __HAVE_ARCH_PTEP_CLEAR in pgtable.h
Date:   Tue, 26 Apr 2022 08:10:34 +0000
Message-ID: <20220426081036.1374452-5-tongtiangen@huawei.com>
In-Reply-To: <20220426081036.1374452-1-tongtiangen@huawei.com>

Precedence: bulk

Currently, there is no architecture definition __HAVE_ARCH_PTEP_CLEAR,
Generic ptep_clear() is the only definition for all architecture, So
drop the "#ifndef __HAVE_ARCH_PTEP_CLEAR".
