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.
