    Merge branch 'parisc-4.9-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
    
    Pull parisc fixes from Helge Deller:
     "On parisc we were still seeing occasional random segmentation faults
      and memory corruption on SMP machines. Dave Anglin then looked again
      at the TLB related code and found two issues in the PCI DMA and
      generic TLB flush functions.
    
      Then, in our startup code we had some timing of the cache and TLB
      functions to calculate a threshold when to use a complete TLB/cache
      flush or just to flush a specific range. This code produced a race
      with newly started CPUs and thus lead to occasional kernel crashes
      (due to stale TLB/cache entries). The patch by Dave fixes this issue
      by flushing the local caches before starting secondary CPUs and by
      removing the race.
    
      The last problem fixed by this series is that we quite often suffered
      from hung tasks and self-detected stalls on the CPUs. It was somehow
      clear that this was related to the (in v4.7) newly introduced cr16
      clocksource and the own implementation of sched_clock(). I replaced
      the open-coded sched_clock() function and switched to the generic
      sched_clock() implementation which seems to have fixed this isse as
      well.
    
      All patches have been sucessfully tested on a variety of machines,
      including our debian buildd servers.
    
      All patches (beside the small pr_cont fix) are tagged for stable
      releases"
