From a92ce8f6ab6cb16006f8d73cb0f522079276fd91 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 3 Apr 2017 19:37:56 +0100 Subject: [PATCH] ARM: KVM: Convert __cpu_reset_hyp_mode to using __hyp_reset_vectors We are now able to use the hyp stub to reset HYP mode. Time to kiss __kvm_hyp_reset goodbye, and use __hyp_reset_vectors.
