Subject: [PATCH v4 57/66] KVM: arm64: nv: Add include containing the VNCR_EL2 offsets
Date: Mon, 10 May 2021 17:59:11 +0100	[thread overview]
Message-ID: <20210510165920.1913477-58-maz@kernel.org> (raw)
In-Reply-To: <20210510165920.1913477-1-maz@kernel.org>

VNCR_EL2 points to a page containing a number of system registers
accessed by a guest hypervisor when ARMv8.4-NV is enabled.

Let's document the offsets in that page, as we are going to use
this layout.
