From a214a8c68bcdef2fb0803425f7fe36fe41030d3f Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Wed, 3 Jul 2013 15:03:40 -0700 Subject: UML: normalize global variables exported by vmlinux.lds Normalize global variables exported by vmlinux.lds to conform usage guidelines from include/asm-generic/sections.h. 1) Use _text to mark the start of the kernel image including the head text, and _stext to mark the start of the .text section. 2) Export mandatory global variables __bss_stop. 3) Adjust __init_begin and __init_end to avoid acrossing .text and .data sections.
