From c967118ddb21191178c0e0080fdc41f5d85ca1d1 Mon Sep 17 00:00:00 2001 From: Jim Mattson Date: Wed, 3 Jun 2020 16:56:23 -0700 Subject: [PATCH] kvm: x86: Set last_vmentry_cpu in vcpu_enter_guest Since this field is now in kvm_vcpu_arch, clean things up a little by setting it in vendor-agnostic code: vcpu_enter_guest. Note that it must be set after the call to kvm_x86_ops.run(), since it can't be updated before pre_sev_run().
