Subject: [PATCH v1 1/6] kselftest/arm64: signal: Add SVE to the set of features we can check for
Date: Thu, 19 Aug 2021 14:42:40 +0100	[thread overview]
Message-ID: <20210819134245.13935-2-broonie@kernel.org> (raw)
In-Reply-To: <20210819134245.13935-1-broonie@kernel.org>

Allow testcases for SVE signal handling to flag the dependency and be
skipped on systems without SVE support.
