Hi Linus,

please pull from the 'for-linus' branch of

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus

to receive the following updates:

* 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.

Arnd Bergmann (1):
s390/dasd: remove 'struct timespec' usage

Heiko Carstens (3):
s390: always save and restore all registers on context switch
s390/mm: fix off-by-one bug in 5-level page table handling
s390: fix compat system call table

Julian Wiedmann (2):
s390/qdio: consider ERROR buffers for inbound-full condition
s390/qdio: restrict target-full handling to IQDIO

Martin Schwidefsky (2):
s390: add a few more SPDX identifiers
s390: Remove redudant license text

Michael S. Tsirkin (1):
s390/virtio: add BSD license to virtio-ccw

Stefan Haberland (1):
s390/dasd: prevent prefix I/O error
