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
