From 1e3479225acbb7ae048ac30fb7c6090fa7f0df02 Mon Sep 17 00:00:00 2001 From: Victor Kamensky Date: Fri, 9 Jan 2015 18:55:45 +0100 Subject: [PATCH] ARM: 8275/1: mm: fix PMD_SECT_RDONLY undeclared compile error MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In v3.19-rc3 tree when CONFIG_ARM_LPAE and CONFIG_DEBUG_RODATA are enabled image failed to compile with the following error: arch/arm/mm/init.c:661:14: error: ‘PMD_SECT_RDONLY’ undeclared here (not in a function) It seems that '80d6b0c ARM: mm: allow text and rodata sections to be read-only' and 'ded9477 ARM: 8109/1: mm: Modify pte_write and pmd_write logic for LPAE' commits crossed. 80d6b0c uses PMD_SECT_RDONLY macro but ded9477 renames it and uses software bits L_PMD_SECT_RDONLY instead. Fix is to use L_PMD_SECT_RDONLY instead PMD_SECT_RDONLY as ded9477 does in another places.
