From 4b5f32cee0cce7b9783ced5cbeabd17aa53c51fb Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Mon, 6 Oct 2008 13:24:40 -0400 Subject: [ARM] rationalize memory configuration code some more Currently there are two instances of struct meminfo: one in kernel/setup.c marked __initdata, and another in mm/init.c with permanent storage. Let's keep only the later to directly populate the permanent version from arm_add_memory(). Also move common validation tests between the MMU and non-MMU cases into arm_add_memory() to remove some duplication. Protection against overflowing the membank array is also moved in there in order to cover the kernel cmdline parsing path as well.
