From de0d22e50cd3d57277f073ccf65d57aa519d6888 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Tue, 30 Oct 2018 15:04:47 -0700 Subject: treewide: remove current_text_addr Prefer _THIS_IP_ defined in linux/kernel.h. Most definitions of current_text_addr were the same as _THIS_IP_, but a few archs had inline assembly instead. This patch removes the final call site of current_text_addr, making all of the definitions dead code.
