Subject: [RFC PATCH v1 08/30] KVM: arm64: add hypervisor state accessors
Date: Fri, 24 Sep 2021 13:53:37 +0100	[thread overview]
Message-ID: <20210924125359.2587041-9-tabba@google.com> (raw)
In-Reply-To: <20210924125359.2587041-1-tabba@google.com>

Part of the state in vcpu_arch is hypervisor-specific. To isolate
that state in future patches, start by creating accessors for
this state rather than by dereferencing vcpu.
