Below is the list of build error/warning regressions/improvements in
v5.3-rc1[1] compared to v5.2[2].

Summarized:
  - build errors: +11/-1
  - build warnings: +54/-144

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.

I've a patch queued up for the next pull request (in the parisc git tree) to fix this:

https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git/commit/?h=for-next&id=f5e03d3a04978d2866f82cb11cc7a6b808c8ce07
