Hi Linus, this is caused by some cherry picked old commits are compiled on one
randconfig, and triggers bisect. The error is discussed before as you may know,
at https://patchwork.kernel.org/patch/9459363/ or
http://lkml.iu.edu/hypermail/linux/kernel/1611.2/01337.html.

The bisect considers the errors belong to mainline tree, meanwhile, there's a
corner case, the bot sends out this mail externally which is supposed to send
only internally for double check.

Kindly ignore this. We will continue the improvement of the bot.
