From 5b0d2cc2805897c14257f6dbb949639c499c3c25 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Sat, 18 Mar 2017 13:56:56 +0100 Subject: KVM: arm64: Ensure LRs are clear when they should be We currently have some code to clear the list registers on GICv3, but we never call this code, because the caller got nuked when removing the old vgic. We also used to have a similar GICv2 part, but that got lost in the process too. Let's reintroduce the logic for GICv2 and call the logic when we initialize the use of hypervisors on the CPU, for example when first loading KVM or when exiting a low power state.
