Subject: [PATCH v1 04/38] arm64/sve: Rename find_supported_vector_length()
Date: Thu, 30 Sep 2021 19:11:10 +0100	[thread overview]
Message-ID: <20210930181144.10029-5-broonie@kernel.org> (raw)
In-Reply-To: <20210930181144.10029-1-broonie@kernel.org>

The function has SVE specific checks in it and it will be more trouble
to add conditional code for SME than it is to simply rename it to be SVE
specific.
