From 5a567d78c437e3be1c512734cdfe64b4ae6b82d7 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Sat, 8 Oct 2011 11:20:42 +0100 Subject: ARM: 7115/4: move __exception and friends to asm/exception.h The definition of __exception_irq_entry for CONFIG_FUNCTION_GRAPH_TRACER=y needs linux/ftrace.h, but this creates a circular dependency with it's current home in asm/system.h. Create asm/exception.h and update all current users. v4: - rebase to rmk/for-next v3: - remove redundant includes of linux/ftrace.h v2: - document the usage restricitions of __exception* Cc: Zoltan Devai Signed-off-by: Jamie Iles Signed-off-by: Russell King --- arch/arm/include/asm/system.h | 7 ------- 1 file changed, 7 deletions(-) (limited to 'arch/arm/include/asm/system.h') diff --git a/arch/arm/include/asm/system.h b/arch/arm/include/asm/system.h index 832888d0c20c..ed6b0499a106 100644 --- a/arch/arm/include/asm/system.h +++ b/arch/arm/include/asm/system.h @@ -62,13 +62,6 @@ #include -#define __exception __attribute__((section(".exception.text"))) -#ifdef CONFIG_FUNCTION_GRAPH_TRACER -#define __exception_irq_entry __irq_entry -#else -#define __exception_irq_entry __exception -#endif - struct thread_info; struct task_struct; -- cgit v1.2.3 From 2ecccf90f2a6d821af4d33f086d59895e5d3bedc Mon Sep 17 00:00:00 2001 From: Dave Martin Date: Fri, 19 Aug 2011 17:58:35 +0100 Subject: ARM: 7029/1: Make cpu_architecture into a global variable The CPU architecture really should not be changing at runtime, so make it a global variable instead of a function. The cpu_architecture() function declared in remains the correct way to read this variable from C code.

Switch to dump_stack which handles both CONFIG_FRAME_POINTER and CONFIG_ARM_UNWIND correctly. __backtrace is now superseded by dump_stack in general and show_regs was the last caller so remove __backtrace as well.
