Subject: [PATCH v4 01/17] arm64: sysreg: Add layout for VNCR_EL2
Date: Wed, 14 May 2025 11:34:44 +0100 [thread overview]
Message-ID: <20250514103501.2225951-2-maz@kernel.org> (raw)
In-Reply-To: <20250514103501.2225951-1-maz@kernel.org>
Now that we're about to emulate VNCR_EL2, we need its full layout.
Add it to the sysreg file.
