From bbc6172eefdb276be140415fd6ac6cc8a14a5263 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 15 Nov 2022 09:46:38 +0000 Subject: arm64/fpsimd: SME no longer requires SVE register state Now that we track the type of the stored register state separately to what is active in the task, it is valid to have the FPSIMD register state stored while in streaming mode. Remove the special case handling for SME when setting FPSIMD register state.
