Below is the list of build error/warning regressions/improvements in
v4.15-rc8[1] compared to v4.14[2].

Summarized:
- build errors: +1/-6
- build warnings: +1306/-827

JFYI, when comparing v4.15-rc8[1] to v4.15-rc7[3], the summaries are:
- build errors: +0/-0
- build warnings: +401/-542

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.
