Subject: [PATCH v11 06/43] KVM: arm64: nv: Add include containing the VNCR_EL2 offsets
Date: Mon, 20 Nov 2023 13:09:50 +0000	[thread overview]
Message-ID: <20231120131027.854038-7-maz@kernel.org> (raw)
In-Reply-To: <20231120131027.854038-1-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.
