2013-12-29ARM: make kernel oops easier to readRussell King1-10/+10
We don't need the offset for the first function name in each backtrace entry; this needlessly consumes screen space. This is virtually always the first or second instruction in the called function. Also, recognise stmfd instructions which include r10 as a valid stack saving instruction, and when dumping the registers, dump six registers per line rather than five, and fix the wrapping.

2011-10-17ARM: 7068/1: process: change from __backtrace to dump_stack in show_regsLaura Abbott1-6/+0
Currently, show_regs calls __backtrace which does nothing if CONFIG_FRAME_POINTER is not set. 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 __backtrace is now superseded by dump_stack in general and show_regs was the last caller so remove __backtrace as well.

2010-04-21ARM: fix build error in arch/arm/kernel/process.cRussell King1-2/+2
/tmp/ccJ3ssZW.s: Assembler messages: /tmp/ccJ3ssZW.s:1952: Error: can't resolve `.text' {.text section} - `.LFB1077' This is caused because: .section .data .section .text .section .text .previous does not return us to the .text section, but the .data section; this makes use of .previous dangerous if the ordering of previous sections is not known. Fix up the other users of .previous; .pushsection and .popsection are a safer pairing to use than .section and .previous. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-07-24Thumb-2: Implement the unified arch/arm/lib functionsCatalin Marinas1-2/+6
This patch adds the ARM/Thumb-2 unified support for the arch/arm/lib/* files. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-09-01[ARM] 5227/1: Add the ENDPROC declarations to the .S filesCatalin Marinas1-0/+4
This declaration specifies the "function" type and size for various assembly functions, mainly needed for generating the correct branch instructions in Thumb-2. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-06-28[ARM] nommu: backtrace code must not reference a discarded sectionRussell King1-4/+1
The code in "1007:" is in the .fixup section, which in the mmuless case is discarded. Since this code is referenced from the .text section, it causes an link error. Move this code into the .text section instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-06-25[ARM] Remove LOADREGS macroRussell King1-4/+4
As for RETINSTR, LOADREGS is a left-over from the 26-bit days. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-05-16[ARM] 3524/1: ARM EABI: more 64-bit aligned stack fixesNicolas Pitre1-2/+2
Patch from Nicolas Pitre Assembly code that calls C code must ensure the C code sees a 64-bit aligned stack pointer. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-03-25[ARM] 3399/1: Fix link problem when CONFIG_PRINTK is disabledMalcolm Parsons1-1/+1
Patch from Malcolm Parsons Printking a backtrace requires printk, so disable backtrace code when printk is disabled. Without this patch, a kernel with CONFIG_PRINTK disabled does not link: arch/arm/lib/lib.a(backtrace.o): In function `c_backtrace': arch/arm/lib/backtrace.S:(.text+0x108): undefined reference to `printk' arch/arm/lib/backtrace.S:(.text+0x11c): undefined reference to `printk' arch/arm/lib/lib.a(backtrace.o):(.fixup+0x8): undefined reference to `printk' Signed-off-by: Malcolm Parsons <malcolm.parsons@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+157
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
