From 6fbab054eccd14480d0c0805cab80db08e0fb3ee Mon Sep 17 00:00:00 2001 From: Jinbum Park Date: Tue, 12 Dec 2017 01:25:30 +0100 Subject: ARM: 8734/1: mm: idmap: Mark variables as ro_after_init idmap_pgd, arch_phys_to_idmap_offset are setup once while init stage, and never changed after that. so, it is good candidate for __ro_after_init.
