Hi Borislav,

Sorry about it, the actual link is at 
https://lists.01.org/hyperkitty/list/kbuild@lists.01.org/thread/PZVMY3VJU4QY4HQXHK3MLPQ2KZ5CNAYH/,
and it's still an internal report that the robot don't know whether it's 
a false positive or not, we'll update the mail contents to avoid 
misunderstanding.

Best Regards,
Rong Chen
