Below is the list of build error/warning regressions/improvements in
v4.12-rc4[1] compared to v4.11[2].

Summarized:
- build errors: +/-3
- build warnings: +27841/-946

JFYI, when comparing v4.12-rc4[1] to v4.12-rc3[3], the summaries are:
- build errors: +/-3
- build warnings: +1324/-1234

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.
