linux-toradex.git/arch/arm/lib/backtrace.S, branch v3.10.2 Linux kernel for Apalis and Colibri modules ARM: 7068/1: process: change from __backtrace to dump_stack in show_regs 2011-10-17T08:12:41+00:00 Laura Abbott lauraa@codeaurora.org 2011-08-31T01:04:06+00:00 b380ab4f85d641574d91b12b333848a0731a497c 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 __backtrace is now superseded by dump_stack in general and show_regs was the last caller so remove __backtrace as well.
