From: Sean Christopherson Date: Fri, 13 Jul 2018 15:42:30 +0000 (-0700) Subject: KVM: vmx: rename KVM_GUEST_CR0_MASK tp KVM_VM_CR0_ALWAYS_OFF X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3de6347bf96abead5c5257b43a58ca0a057df894;p=openwrt%2Fstaging%2Fblogic.git KVM: vmx: rename KVM_GUEST_CR0_MASK tp KVM_VM_CR0_ALWAYS_OFF The KVM_GUEST_CR0_MASK macro tracks CR0 bits that are forced to zero by the VMX architecture, i.e. CR0.{NW,CD} must always be zero in the hardware CR0 post-VMXON. Rename the macro to clarify its purpose, be consistent with KVM_VM_CR0_ALWAYS_ON and avoid confusion with the CR0_GUEST_HOST_MASK field.
