From cb7c4f364abd09abd1865fa049ef492fb43e6bf3 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 27 Dec 2021 12:48:04 +0000 Subject: [PATCH] KVM: selftests: arm64: Initialise default guest mode at test startup time As we are going to add support for a variable default mode on arm64, let's make sure it is setup first by using a constructor that gets called before the actual test runs.
