From: Russell King Date: Mon, 1 Dec 2008 11:53:07 +0000 (+0000) Subject: [ARM] use asm/sections.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=37efe6427dd50e889473fb3c7fcec02dbbd098eb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [ARM] use asm/sections.h Update to use the asm/sections.h header rather than declaring these symbols ourselves. Change __data_start to _data to conform with the naming found within asm/sections.h.
