From 63d7c6afc510a4a6265b119f7b988af0cc118889 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 9 Mar 2017 21:51:59 +0100 Subject: [PATCH] arm: kvm: move kvm_vgic_global_state out of .text section The kvm_vgic_global_state struct contains a static key which is written to by jump_label_init() at boot time. So in preparation of making .text regions truly (well, almost truly) read-only, mark kvm_vgic_global_state __ro_after_init so it moves to the .rodata section instead.
