From 837d632a383f13df7a67207a196d6eb4aeb4adca Mon Sep 17 00:00:00 2001 From: Vincent Donnefort Date: Tue, 4 Oct 2022 16:42:16 +0100 Subject: KVM: arm64: Enable stack protection and branch profiling for VHE For historical reasons, the VHE code inherited the build configuration from nVHE. Now those two parts have their own folder and makefile, we can enable stack protection and branch profiling for VHE.
