From 2020a5ae7c8c2c8504565004915017507b135c63 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Thu, 3 Nov 2016 20:23:07 +0000 Subject: [PATCH] arm64: unexport walk_stackframe The walk_stackframe functions is architecture-specific, with a varying prototype, and common code should not use it directly. None of its current users can be built as modules. With THREAD_INFO_IN_TASK, users will also need to hold a stack reference before calling it. There's no reason for it to be exported, and it's very easy to misuse, so unexport it for now.
