Subject: [PATCH v11 39/39] KVM: selftests: arm64: Add GCS registers to get-reg-list
Date: Thu, 22 Aug 2024 02:15:42 +0100	[thread overview]
Message-ID: <20240822-arm64-gcs-v11-39-41b81947ecb5@kernel.org> (raw)
In-Reply-To: <20240822-arm64-gcs-v11-0-41b81947ecb5@kernel.org>

GCS adds new registers GCSCR_EL1, GCSCRE0_EL1, GCSPR_EL1 and GCSPR_EL0. Add
these to those validated by get-reg-list.
