commit 8db7b3c54401d83a4dc370a59b8692854000ea03
Merge: 682cb0c 71a71fb

    Merge branch 'parisc-4.4-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
    
    Pull parisc system call restart fix from Helge Deller:
     "The architectural design of parisc always uses two instructions to
      call kernel syscalls (delayed branch feature).  This means that the
      instruction following the branch (located in the delay slot of the
      branch instruction) is executed before control passes to the branch
      destination.
    
      Depending on which assembler instruction and how it is used in
      usersapce in the delay slot, this sometimes made restarted syscalls
      like futex() and poll() failing with -ENOSYS"
