From: Stephen Warren <[email protected]> Macro __INIT is used to place various code in head-common.S into the init section. This should be matched by a closing __FINIT at the end of the code destined for the init section. Add this missing macro.
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. Signed-off-by: Stephen Warren <[email protected]> Acked-by: Paul Gortmaker <[email protected]> --- v2: Moved __FINIT after lookup_processor_type, to correctly match the location of __CPUINIT. Russell, I assume I should add this to the ARM patch tracker. This version is based on v3.10. --- arch/arm/kernel/head-common.S | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/kernel/head-common.S b/arch/arm/kernel/head-common.S index 5b391a6..1fb887d 100644 --- a/arch/arm/kernel/head-common.S +++ b/arch/arm/kernel/head-common.S @@ -133,6 +133,8 @@ ENTRY(lookup_processor_type) ldmfd sp!, {r4 - r6, r9, pc} ENDPROC(lookup_processor_type) + __FINIT + /* * Read processor ID register (CP#15, CR0), and look up in the linker-built * supported processor list.
