Subject: [PATCH v2 1/6] KVM: selftests: arm64: Initialise default guest mode at test startup time
Date: Mon, 27 Dec 2021 12:48:04 +0000	[thread overview]
Message-ID: <20211227124809.1335409-2-maz@kernel.org> (raw)
In-Reply-To: <20211227124809.1335409-1-maz@kernel.org>

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.
