Let me know if you want me to send v13 before testing or you can just use  
the sgx_cg_upstream_v12_plus branch in my repo.

Also thanks for the "Reviewed-by" tags for other patches. But I've not got  
"Reviewed-by" from you for patches #8-12 (not sure I missed). Could you go  
through those alsoe when you get chance?

Thanks
Haitao
