Subject: [PATCH 01/14] arm64: sysreg: Add layout for VNCR_EL2
Date: Sat, 15 Feb 2025 15:01:21 +0000	[thread overview]
Message-ID: <20250215150134.3765791-2-maz@kernel.org> (raw)
In-Reply-To: <20250215150134.3765791-1-maz@kernel.org>

Now that we're about to emulate VNCR_EL2, we need its full layout.
Add it to the sysreg file.
