Subject: [PATCH] arm: 9016/2: Make symbol 'tmp_pmd_table' static
Date:   Sat, 27 Mar 2021 16:30:18 +0800
Message-ID: <20210327083018.1922539-1-liushixin2@huawei.com>
MIME-Version: 1.0

Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

Symbol 'tmp_pmd_table' is not used outside of kasan_init.c and only used
when CONFIG_ARM_LPAE enabled. So marks it static and add it into CONFIG_ARM_LPAE.
