From 0f5bf6d0afe4be6e1391908ff2d6dc9730e91550 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 6 Feb 2017 16:31:58 -0800 Subject: arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX Both of these options are poorly named. The features they provide are necessary for system security and should not be considered debug only. Change the names to CONFIG_STRICT_KERNEL_RWX and CONFIG_STRICT_MODULE_RWX to better describe what these options do.
