From: Damien Le Moal <damien.lemoal@xxxxxxx> [ Upstream commit aa2734202acc506d09c8e641db4da161f902df27 ] Compilation errors trigger if ARCH_SPARSEMEM_ENABLE is enabled for a nommu kernel. Since the sparsemem model does not make sense anyway for the nommu case, do not allow selecting this option to always use the flatmem model.
