Below is the list of build error/warning regressions/improvements in
v4.8-rc6[1] compared to v4.7[2].

Summarized:
  - build errors: +10/-12
  - build warnings: +1237/-938

JFYI, when comparing v4.8-rc6[1] to v4.8-rc5[3], the summaries are:
  - build errors: +3/-1
  - build warnings: +320/-516

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

As I haven't mastered kup yet, there's no verbose summary at
http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/v4.8-rc6.summary.gz

Happy fixing! ;-)

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