Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Martin Schwidefsky:

 - three more patches in regard to the SPDX license tags. The missing
   tags for the files in arch/s390/kvm will be merged via the KVM tree.
   With that all s390 related files should have their SPDX tags.

 - a patch to get rid of 'struct timespec' in the DASD driver.

 - bug fixes

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390: fix compat system call table
  s390/mm: fix off-by-one bug in 5-level page table handling
  s390: Remove redudant license text
  s390: add a few more SPDX identifiers
  s390/dasd: prevent prefix I/O error
  s390: always save and restore all registers on context switch
  s390/dasd: remove 'struct timespec' usage
  s390/qdio: restrict target-full handling to IQDIO
  s390/qdio: consider ERROR buffers for inbound-full condition
  s390/virtio: add BSD license to virtio-ccw
