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.
