Subject: Build regressions/improvements in v5.18

Below is the list of build error/warning regressions/improvements in
v5.18[1] compared to v5.17[2].

Summarized:
  - build errors: +15/-5
  - build warnings: +36/-21

JFYI, when comparing v5.18[1] to v5.18-rc7[3], the summaries are:
  - build errors: +0/-1
  - 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.
