Subject: [PATCH v2 01/10] kselftest/arm64: Enumerate SME rather than SVE vector lengths for za_regs
Date: Mon, 29 Aug 2022 17:06:54 +0100	[thread overview]
Message-ID: <20220829160703.874492-2-broonie@kernel.org> (raw)
In-Reply-To: <20220829160703.874492-1-broonie@kernel.org>

The za_regs signal test was enumerating the SVE vector lengths rather than
the SME vector lengths through cut'n'paste error when determining what to
test. Enumerate the SME vector lengths instead.
