From 7aa8d14641651a61a0b8892314a0bcfaceebe158 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sat, 5 Jan 2019 15:49:50 +0000 Subject: arm/arm64: KVM: Introduce kvm_call_hyp_ret() Until now, we haven't differentiated between HYP calls that have a return value and those who don't. As we're about to change this, introduce kvm_call_hyp_ret(), and change all call sites that actually make use of a return value.
