For the other archs, the patches also don't add declarations in a switch/case. I also checked that there are no new W=2 warnings for the touched C files on x86 with the vmtest bpf config. I have not checked that all files that include a touched header don't have new warnings. When doing -j $(nproc) the diff does not work and with -j 1 it takes forever (e.g., because bpf.h is touched). If you think this is required just let me know (and if you have a tip on how to do it more quickly that would be great too).
