From f3d0040ef2c1ad722aa314723ff4264d0cfba2fa Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 22 Nov 2021 15:59:23 +0000 Subject: [PATCH] BACKPORT: KVM: arm64: Remove unused __sve_save_state Now that we don't have any users left for __sve_save_state, remove it altogether. Should we ever need to save the SVE state from the hypervisor again, we can always re-introduce it.
