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.
