    kernel - Make sys_ioctl() MPSAFE
    
    * Tokenize the ioctl mapper and stay MPSAFE through the fo_ioctl() call.
      Beyond that it will be determined by the fops driver and for vnodes
      will be determined by the MNTK_*_MPSAFE flags.
    
    * HAMMER's ioctls will now be entered without holding the MP lock, aka
      reblock, prune.
