From 4cdecaba0146481f1503a645b8a5a41c1e8566c9 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Tue, 10 Oct 2017 22:40:13 +0200 Subject: KVM: arm64: Unify non-VHE host/guest sysreg save and restore functions There is no need to have multiple identical functions with different names for saving host and guest state. When saving and restoring state for the host and guest, the state is the same for both contexts, and that's why we have the kvm_cpu_context structure. Delete one version and rename the other into simply save/restore.
