Subject: [PATCH] mm: do not export ioremap_page_range symbol for external module
Date: Sun, 22 Jan 2017 20:58:01 +0800 [thread overview]
Message-ID: <1485089881-61531-1-git-send-email-zhongjiang@huawei.com> (raw)
From: zhong jiang <zhongjiang@huawei.com>
Recently, I find the ioremap_page_range had been abusing. The improper
address mapping is a issue. it will result in the crash. so, remove
the symbol. It can be replaced by the ioremap_cache or others symbol.
