Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull more s390 updates from Martin Schwidefsky:
 "The second patch set for the 4.14 merge window:

   - Convert the dasd device driver to the blk-mq interface.

   - Provide three zcrypt interfaces for vfio_ap. These will be required
     for KVM guest access to the crypto cards attached via the AP bus.

   - A couple of memory management bug fixes."
