I only looked at docs. But Andrew Morton said: "Your new code should really be generic, utilising the stack-page-zeroing which CONFIG_DEBUG_STACK_USAGE enables." In fact, the other reference is in kernel/sched.c. You may (or may not) join the two stack walking (I would) and match a bit descriptions. Personally, I'd put the Kconfig option in lib/Kconfig.debug and have a Kconfig flag named DEBUG_STACK_USAGE_SUPPORT, much like LOCKDEP_SUPPORT (defined only by architectures supporting the option), but have no time right now.
