There are many Sparse warnings in the kernel, including the powerpc directory. This series provides fixes for some low-hanging fruit found when trying to triage the warnings earlier this year. It addresses about 100 warnings (many have the same root cause).
I know there's concerns about making it harder to backport things. In general, as someone who was not around during the development of these features, I think that it is useful make the annotations as correct as possible. But it's no fuss if some/all of the patches are nacked for this reason. I just figured some of it might be useful instead of continuing to sit on it indefinitely.
