I think that this problem is similar to the one on s390 that was solved by compiler.h in arch/s390/include/asm/bug.h It is related to https://lore.kernel.org/r/20200613142901.65xieioomt6bbqa6@ltop.local It seems that we need the same change also in list.h. > Did you get a compile failure with *just* the lockdep > patch?

Do you mean to repost the 2nd patch with the change in include/linux/list.h? This would be great. Best Regards, Petr
