mm/filemap: change filemap_read_page calling conventions
Make this function more generic by passing the file instead of the iocb. Check in the callers whether we should call readpage or not. Also make it return an errno / 0 / AOP_TRUNCATED_PAGE, and make calling put_page() the caller's responsibility.
