Hi, s390 builds in -next fail with lots of errors such as: include/linux/jump_label.h: In function 'static_key_count': include/linux/jump_label.h:122:2: error: implicit declaration of function 'atomic_read' [-Werror=implicit-function-declaration] return atomic_read(&key->enabled); ... ./arch/s390/include/asm/atomic.h: At top level: ./arch/s390/include/asm/atomic.h:74:19: error: static declaration of 'atomic_read' follows non-static declaration static inline int atomic_read(const atomic_t *v) As far as I can see this is due to recursive inclusion of linux/atomic.h (which in turn is triggered by recursive inclusion of linux/mmdebug.h). I was able to "fix" the problem by removing the inclusion of mmdebug.h from arch/s390/include/asm/cmpxchg.h. That is not a proper fix, though, since the file uses VM_BUG_ON(), which is defined in mmdebug.h. The problem was introduced with 'mm, printk: introduce new format string for flags'.
