If you want I can send the other reports also. Sure! I am not sure that we have tested mips or powerpc allmodconfig now that I am thinking about it but we'll certainly take a look at any issues that come from them and see what we can do. arm and arm64 are not warning free so disabling CONFIG_WERROR will help out there (arm64 is a recent failure that I have not been able to entirely figure out: https://github.com/ClangBuiltLinux/linux/issues/1642) but I do want to get those warning clean soon so they just build out of the box.
