Pull s390 updates from Martin Schwidefsky:
 "The first part of the s390 updates for 4.14:

   - Add machine type 0x3906 for IBM z14

   - Add IBM z14 TLB flushing improvements for KVM guests

   - Exploit the TOD clock epoch extension to provide a continuous TOD
     clock afer 2042/09/17

   - Add NIAI spinlock hints for IBM z14

   - Rework the vmcp driver and use CMA for the respone buffer of z/VM
     CP commands

   - Drop some s390 specific asm headers and use the generic version

   - Add block discard for DASD-FBA devices under z/VM

   - Add average request times to DASD statistics

   - A few of those constify patches which seem to be in vogue right now

   - Cleanup and bug fixes"
