I actually don't want to, even though it seems like a no-brainer at first glance,
because it would require exporting __kvm_set_rflags() to vendor code.  Which
wouldn't be terrible, but it seems like an unnecessary "risk", e.g. of folks
trying to micro-optimize vendor flows to avoid the KVM_REQ_EVENT.
