Subject: [PATCH v3 01/17] arm64/sysreg: Add missing Pauth_LR field definitions to ID_AA64ISAR1_EL1
Date: Thu, 14 Dec 2023 10:01:41 +0000	[thread overview]
Message-ID: <20231214100158.2305400-2-tabba@google.com> (raw)
In-Reply-To: <20231214100158.2305400-1-tabba@google.com>

Add the Pauth_LR field definitions to ID_AA64ISAR1_EL1, based on
DDI0601 2023-09.

These fields aren't used yet. Adding them for completeness and
consistency (definition already exists for ID_AA64ISAR2_EL1).
