From f133f22dd6f413bdf71ebf7e00ce441d98ac7c87 Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Tue, 1 Dec 2009 14:55:42 +0800 Subject: [PATCH] MIPS: Loongson: Switch from flatmem to sparsemem With flatmem hibernation for Loongson will fail, and there are also some other problems such as broken files when using NFS or CIFS / Samba. 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.
