Message-Id: <1394192571-11056-2-git-send-email-pbonzini@redhat.com> Date: Fri, 7 Mar 2014 12:42:45 +0100 From: Paolo Bonzini <pbonzini@...hat.com> To: linux-kernel@...r.kernel.org Cc: kvm@...r.kernel.org, alex.williamson@...hat.com, mtosatti@...hat.com, gleb@...nel.org, jan.kiszka@...mens.com Subject: [PATCH 1/7] KVM: vmx: we do rely on loading DR7 on entry Currently, this works even if the bit is not in "min", because the bit is always set in MSR_IA32_VMX_ENTRY_CTLS. Mention it for the sake of documentation, and to avoid surprises if we later switch to MSR_IA32_VMX_TRUE_ENTRY_CTLS.
