    Pull parisc fixes from Helge Deller:
     "There are two patches in here:
    
      The first patch greatly improves latency and corrects the memory
      ordering in our light-weight atomic locking syscall.
    
      The second patch ratelimits printing of userspace segfaults in the
      same way as it's done on other platforms.  This fixes a possible DOS
      on parisc since it prevents the syslog to grow too fast.  For example,
      when the debian acl2 package was built on our debian buildd servers,
      this package produced lots of gigabytes in syslog in very short time
      and thus filled our harddisks, which then turned the server nearly
      completely unaccessible and unresponsive"
