[PATCH v10 01/11] arm64: Select STACKTRACE in arch/arm64/Kconfig

From: <hidden>
Date: 2021-10-15 02:59:09
Also in: linux-arm-kernel, lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

From: "Madhavan T. Venkataraman" <redacted>

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.
