From 404f6aac9b3ef595735feca99979db084ea48315 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 8 Aug 2016 16:29:06 -0700 Subject: x86: Apply more __ro_after_init and const Guided by grsecurity's analogous __read_only markings in arch/x86, this applies several uses of __ro_after_init to structures that are only updated during __init, and const for some structures that are never updated. Additionally extends __init markings to some functions that are only used during __init, and cleans up some missing C99 style static initializers.
