Minimize casts to pointers

[cagatay-y]

Minimize casts to pointers by using:

• pointer formatting,
• from_exposed_addr{,_mut},
• from_{ref,mut} (solves Consider adopting ptr_from_ref #793),
• as_str
• and some other methods.

CI failure is being fixed in #965.

Thanks a lot! :)

Could you rebase on main instead of merging main? I'd like to avoid merge commits in feature branches.

Also, it would be great if you could have the CI run all of these commits. I usually do that by force pushing the first commit of the feature branch and then pushing commit by commit. Something like git push origin HEAD~10:cast-elimination --force should work (--force can be omitted on all but the first push).

I can also recomment git-interactive-rebase-tool, but any editor of your choice works just as well for rebases.

As a side note, you don't have to wait for CI to finish before pushing the next commit. :)

Awesome. You also don't need to be up to date with main and rebase on every change, but having a green CI everywhere would be great. :)

I completely misread this message the first time and thought that you said I have to wait :) Thanks for the tip!

I did cancel the CI runs starting from the first unsuccessful one, so this does not block the CI. I think, you should be able to do that too if rights are configured correctly: https://github.com/hermit-os/kernel/actions

Perfect! 👌

Thanks a lot! :)
