From 27588702a6792ff86a57317ef60d6e218796598e Mon Sep 17 00:00:00 2001
From: Ralf Ramsauer <ralf.ramsauer@oth-regensburg.de>
Date: Wed, 7 Jun 2017 15:48:43 +0200
Subject: [PATCH 06/32] arm, arm64: export __hyp_stub_vectors

HVC_GET_VECTORS got removed. External hypervisors, like Jailhouse, need
this address when they are deactivated, in order to restore original
state.
