So what causes this? Because we got a couple of these in our s390 builds last night as well.
kernel/locking/lockdep.c:805:1: error: inlining failed in call to always_inline 'look_up_lock_class': function attribute mismatch
include/linux/debug_locks.h:15:28: error: inlining failed in call to always_inline '__debug_locks_off': function attribute mismatch
s390-linux-gcc (GCC) 8.1.0 / GNU ld (GNU Binutils) 2.30
