Subject: [PATCH v6 05/12] KVM: arm64: Pass struct kvm to per-EC handlers
Date: Wed, 22 Sep 2021 13:46:57 +0100 [thread overview]
Message-ID: <20210922124704.600087-6-tabba@google.com> (raw)
In-Reply-To: <20210922124704.600087-1-tabba@google.com>
We need struct kvm to check for protected VMs to be able to pick
the right handlers for them in subsequent patches.
