From: "Madhavan T. Venkataraman" <madvenka@xxxxxxxxxxxxxxxxxxx> Currently, there are multiple functions in ARM64 code that walk the stack using start_backtrace() and unwind_frame() or start_backtrace() and walk_stackframe(). They should all be converted to use arch_stack_walk(). This makes maintenance easier. To do that, arch_stack_walk() must always be defined. arch_stack_walk() is within #ifdef CONFIG_STACKTRACE. So, select STACKTRACE in arch/arm64/Kconfig. Signed-off-by: Madhavan T.
