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

Pull s390 updates from Martin Schwidefsky:
 "The s390 patches for the 4.7 merge window have the usual bug fixes and
  cleanups, and the following new features:

   - An interface for dasd driver to query if a volume is online to
     another operating system

   - A new ioctl for the dasd driver to verify the format for a range of
     tracks

   - Following the example of x86 the struct fpu is now allocated with
     the task_struct

   - The 'report_error' interface for the PCI bus to send an
     adapter-error notification from user space to the service element
     of the machine"
