[PATCH] mm: do not export ioremap_page_range symbol for external module

Show all headers | View 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.
