Mike Rapoport 4fabcf2294 nds32: flush_dcache_page: use page_mapping_file to avoid races with swapoff ... commit a3a8833dff upstream. Commit cb9f753a37 ("mm: fix races between swapoff and flush dcache") updated flush_dcache_page implementations on several architectures to use page_mapping_file() in order to avoid races between page_mapping() and swapoff(). This update missed arch/nds32 and there is a possibility of a race there. Replace page_mapping() with page_mapping_file() in nds32 implementation of flush_dcache_page().
