From 0546c63d988d347fc734fc8c624692b30f95f633 Mon Sep 17 00:00:00 2001 From: "Longpeng(Mike)" Date: Tue, 8 Aug 2017 12:05:34 +0800 Subject: [PATCH] KVM: s390: implements the kvm_arch_vcpu_in_kernel() This implements kvm_arch_vcpu_in_kernel() for s390. DIAG is a privileged operation, so it cannot be called from problem state (user mode).
