Subject: Build regressions/improvements in v6.6-rc3

Below is the list of build error/warning regressions/improvements in
v6.6-rc3[1] compared to v6.5[2].

Summarized:
  - build errors: +4/-5
  - build warnings: +36/-6

JFYI, when comparing v6.6-rc3[1] to v6.6-rc2[3], the summaries are:
  - build errors: +11/-4
  - build warnings: +1479/-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.
