From a8ee48a8d80268ae7a19c0677ad8d055bc815775 Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Wed, 19 Jun 2013 10:06:23 +1000 Subject: [PATCH] c6x: normalize global variables exported by vmlinux.lds Normalize global variables exported by vmlinux.lds to conform usage guidelines from include/asm-generic/sections.h. Use _text to mark the start of the kernel image including the head text, and _stext to mark the start of the .text section. This patch also fixes possible bugs due to current address layout that [__init_begin, __init_end] is a sub-range of [_stext, _etext] and pages within range [__init_begin, __init_end] will be freed by free_initmem().
