From 8c69d7af12265e5be9326110b695e010b47505bd Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 5 Jul 2013 22:59:42 +0100 Subject: ARM: 7780/1: add missing linker section markup to head-common.S Macro __INIT is used to place various code in head-common.S into the init section. This should be matched by a closing __FINIT. Also, add an explicit ".text" to ensure subsequent code is placed into the correct section; __FINIT is simply a closing marker to match __INIT and doesn't guarantee to revert to .text. This historically caused no problem, because macro __CPUINIT was used at the exact location where __FINIT was missing, which then placed following code into the cpuinit section. However, with commit 22f0a2736 "init.h: remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a no-op, thus leaving all this code in the init section, rather than the regular text section. This caused issues such as secondary CPU boot failures or crashes.
