Below is the list of build error/warning regressions/improvements in
v4.16-rc1[1] compared to v4.15[2].

Summarized:
  - build errors: +13/-5
  - build warnings: +1653/-1537

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.
