A series that fixes up build errors and warnings for at least the 64-bit builds on x86 with clang. The series also includes an optional "improvement" of moving some uffd code into uffd-common.[ch], which is proving to be somewhat controversial, and so if that doesn't get resolved, then patches 9 and 10 may just get dropped. They are not required in order to get a clean build, now that "make headers" is happening. [1]: https://lore.kernel.org/all/20230602013358.900637-1-jhubbard@nvidia.com/ This patch (of 11): uffd_minor_feature() was unused. Remove it in order to fix the associated clang build warning.
