Pull s390 updates from Martin Schwidefsky:
 "The main bulk of the s390 patches for the 4.10 merge window:

   - Add support for the contiguous memory allocator.

   - The recovery for I/O errors in the dasd device driver is improved,
     the driver will now remove channel paths that are not working
     properly.

   - Additional fields are added to /proc/sysinfo, the extended
     partition name and the partition UUID.

   - New naming for PCI devices with system defined UIDs.

   - The last few remaining alloc_bootmem calls are converted to
     memblock.

   - The thread_info structure is stripped down and moved to the
     task_struct. The only field left in thread_info is the flags field.

   - Rework of the arch topology code to fix a fake numa issue.

   - Refactoring of the atomic primitives and add a new preempt_count
     implementation.

   - Clocksource steering for the STP sync check offsets.

   - The s390 specific headers are changed to make them usable with
     CLANG.

   - Bug fixes and cleanup"
