Message-ID: <1249638588-10982-19-git-send-email-joerg.roedel@amd.com> Date: Fri, 7 Aug 2009 11:49:45 +0200 From: Joerg Roedel <joerg.roedel@....com> To: Avi Kivity <avi@...hat.com> CC: Alexander Graf <agraf@...e.de>, kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Joerg Roedel <joerg.roedel@....com> Subject: [PATCH 18/21] kvm/svm: remove unnecessary is_nested check from svm_cpu_run This check is not necessary. We have to sync the vcpu->arch.cr2 always back to the VMCB. This patch remove the is_nested check.
