Subject: [PATCH v3 15/18] KVM: arm64: nVHE: Pass pointers consistently to hyp-init
Date: Thu, 3 Sep 2020 14:53:04 +0100 [thread overview]
Message-ID: <20200903135307.251331-16-ascull@google.com> (raw)
In-Reply-To: <20200903135307.251331-1-ascull@google.com>
Rather than some being kernel pointer and others being hyp pointers,
standardize on all pointers being hyp pointers.
