    Pull s390 updates from Martin Schwidefsky:
     "The most notable change for this pull request is the ftrace rework
      from Heiko.  It brings a small performance improvement and the ground
      work to support a new gcc option to replace the mcount blocks with a
      single nop.
    
      Two new s390 specific system calls are added to emulate user space
      mmio for PCI, an artifact of the how PCI memory is accessed.
    
      Two patches for the memory management with changes to common code.
      For KVM mm_forbids_zeropage is added which disables the empty zero
      page for an mm that is used by a KVM process.  And an optimization,
      pmdp_get_and_clear_full is added analog to ptep_get_and_clear_full.
    
      Some micro optimization for the cmpxchg and the spinlock code.
    
      And as usual bug fixes and cleanups"
