#     Merge tag 's390-5.3-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 updates from Heiko Carstens:
#     
#      - Add ABI to kernel image file which allows e.g. the file utility to
#        figure out the kernel version.
#     
#      - Wire up clone3 system call.
#     
#      - Add support for kasan bitops instrumentation.
#     
#      - uapi header cleanup: use __u{16,32,64} instead of uint{16,32,64}_t.
#     
#      - Provide proper ARCH_ZONE_DMA_BITS so the s390 DMA zone is correctly
#        defined with 2 GB instead of the default value of 1 MB.
#     
#      - Farhan Ali leaves the group of vfio-ccw maintainers.
#     
#      - Various small vfio-ccw fixes.
#     
#      - Add missing locking for airq_areas array in virtio code.
#     
#      - Minor qdio improvements.
