From 9d609649bb29a882e7e6bf502adb45dcac178fe5 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 15 Apr 2019 15:14:32 +0200 Subject: [PATCH] KVM: vmx: print more APICv fields in dump_vmcs The SVI, RVI, virtual-APIC page address and APIC-access page address fields were left out of dump_vmcs. Add them. KERN_CONT technically isn't SMP safe, but it's okay to use it here since the whole of dump_vmcs() is a single huge multi-line piece of output that isn't SMP-safe.
