The list was only the 'defconfig' warnings, there are a couple more that I saw with 'allmodconfig', and I'm sure there are even more when dealing with other random configurations. I did send other fixes for microblaze and parisc specific drivers, and I could also send patches for the two defconfig warnings if the maintainers are happy with fixing those but leaving allmodconfig to still warn, but I feel that it's easier for them to just do the last fixes themselves and then remove my hack again. I'll wait for Michal and Helge on these. > Others like loongarch which is a recent actively maintained > architecture, I'd expect the 30 errors to be easy to fix.

In the end it's a matter of where to stop, as there are endless configurations to test if I want to do a complete job. I drew the line between powerpc (which I tried to fix) and mips (which I left alone), mainly because the powerpc side was already exhausting and mips has even more obscure configurations. The other ones on the list are all less actively maintained than these two. Arnd

Arnd, I like your patch! For parisc I've done quite some work during the last few weeks to get such warnings sqeezed out, so please drop the hunk for parisc from your patch. My plan is to become warning-free before 6.5-final. This last one: arch/parisc/lib/ucmpdi2.c:12:5: error: no previous prototype for '__ucmpdi2' [-Werror=missing-prototypes] I'll take care in the parisc for-next tree. Thanks!

Sounds good to me, thanks! Arnd
Thx, Arnd, I will clean them up for the csky part.

Likewise, I'll clean up ARC errors this weekend !
It seems most of therm are in the category you mentioned. Non static but
only used by asm code.
Thx,

Since we already have the majority of architecture maintainers stepping in to fix the warnings, I wonder if I should just drop my patch 16/17 completely and let the others handle it as well rather than shutting up the warnings. Only the asm-offsets change is really needed to compile test most of the kernel even with CONFIG_WERROR, and without that this is just some harmless output. Arnd
