Pull s390 fixes from Heiko Carstens:
- Split kernel large page mappings into 4k mappings in case debug
pagealloc is enabled again. This got accidentally removed by commit
bb1520d581a3 ("s390/mm: start kernel with DAT enabled")
- Fix error handling in KVM's sthyi handling
- Add missing include to s390's uapi ptrace.h
- Update defconfigs
