Linux 6.14 adds get_entry_info. For lack of a better place, I added it
in this patch when rebasing kvm-coco-queue:

static void vt_get_entry_info(struct kvm_vcpu *vcpu, u32 *intr_info, u32 *error_code)
{
	*intr_info = 0;
	*error_code = 0;

	if (is_td_vcpu(vcpu))
		return;

	vmx_get_entry_info(vcpu, intr_info, error_code);
}

Thanks,

Paolo
