Subject: Build regressions/improvements in v5.19-rc2

Below is the list of build error/warning regressions/improvements in
v5.19-rc2[1] compared to v5.18[2].

Summarized:
  - build errors: +7/-10
  - build warnings: +3/-25

JFYI, when comparing v5.19-rc2[1] to v5.19-rc1[3], the summaries are:
  - build errors: +0/-2
  - build warnings: +0/-1

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.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
