Looks pretty good overall.

Requests on the git side:
Ticket reference in the git commit.

Suggestion for the commit subject "os: support Solaris and Sparc"

[victorjulien]

would like to keep this manually formatted, so it would need to be wrapped in clang-format exclusion comments

[victorjulien]

Would like to see this be a bit more compact, like in a helper func that is just called from here

Will return it back. Where are the exlusion comments? Should I do it?
