From 059613f546b67423a5b49cb6e6fa8b72fbaa4e0b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 19 Oct 2021 18:22:10 +0100 Subject: [PATCH] arm64/sve: Rename find_supported_vector_length() 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.
