Subject: [PATCH v4 16/21] kselftest/arm64: Enumerate SME2 in the signal test utility code
Date: Mon, 16 Jan 2023 16:04:51 +0000	[thread overview]
Message-ID: <20221208-arm64-sme2-v4-16-f2fa0aef982f@kernel.org> (raw)
In-Reply-To: <20221208-arm64-sme2-v4-0-f2fa0aef982f@kernel.org>

Support test cases for SME2 by adding it to the set of features that we
enumerate so test cases can check for it.
