Subject: [PATCH v6 58/64] KVM: arm64: nv: Move nested vgic state into the sysreg file
Date: Fri, 28 Jan 2022 12:19:06 +0000 [thread overview]
Message-ID: <20220128121912.509006-59-maz@kernel.org> (raw)
In-Reply-To: <20220128121912.509006-1-maz@kernel.org>
The vgic nested state needs to be accessible from the VNCR page, and
thus needs to be part of the normal sysreg file. Let's move it there.
