I usually try to fix warnings when I get them, but the entire point why these still exist is that they require someone to add the syscall with the correct calling conventions for the respective architecture and make sure this actually works correctly. I don't think any of those architecture maintainers are paying attention to the build warnings or the lkp reports, and they are clearly not trying to fix them any more, so maybe it's better to just stop testing them in lkp.
