Subject: Build regressions/improvements in v5.8-rc6

Below is the list of build error/warning regressions/improvements in
v5.8-rc6[1] compared to v5.7[2].

Summarized:
  - build errors: +7/-1
  - build warnings: +35/-85

JFYI, when comparing v5.8-rc6[1] to v5.8-rc5[3], the summaries are:
  - build errors: +6/-3
  - build warnings: +0/-48

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.

when I'm talking to journalists I just say "programmer" or something like that.
