Subject: Build regressions/improvements in v6.11-rc2

Below is the list of build error/warning regressions/improvements in
v6.11-rc2[1] compared to v6.10[2].

Summarized:
  - build errors: +9/-20
  - build warnings: +2/-19

JFYI, when comparing v6.11-rc2[1] to v6.11-rc1[3], the summaries are:
  - build errors: +9/-4
  - build warnings: +0/-2

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
