Subject: [PATCH v6 4/5] KVM: arm64: selftests: Document feature registers added in 2023 extensions
Date: Fri, 29 Mar 2024 00:13:45 +0000	[thread overview]
Message-ID: <20240329-arm64-2023-dpisa-v6-4-ba42db6c27f3@kernel.org> (raw)
In-Reply-To: <20240329-arm64-2023-dpisa-v6-0-ba42db6c27f3@kernel.org>

The 2023 architecture extensions allocated some previously usused feature
registers, add comments mapping the names in get-reg-list as we do for the
other allocated registers.
