Subject: Build regressions/improvements in v5.17

Below is the list of build error/warning regressions/improvements in
v5.17[1] compared to v5.16[2].

Summarized:
  - build errors: +12/-2
  - build warnings: +23/-27

JFYI, when comparing v5.17[1] to v5.17-rc8[3], the summaries are:
  - build errors: +5/-0
  - build warnings: +0/-0

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.
