From: Wu Zhangjin <wuzhangjin@xxxxxxxxx> With FLATMEM, The STD(Hibernation) for Loongson will fail, and there are also some other problems(break the files) when using NFS or CIFS(samba). And as the config help of SPARSEMEM says: "This option provides some potential performance benefits, along with decreased code complexity." So, to avoid the potential problems of FLATMEM, we disable FLATMEM directly and use SPARSEMEM instead.
