      [PATCH] fix AB-BA deadlock inversion at cs46xx_dsp_remove_scb · c6482dde
      Arjan van de Ven authored
      There is a code sequence where the locking is substream->self_group.lock
      -> ins->scbs[index].lock
      
      substream->self_group.lock is interrupt safe, and taken from irq context
      as well (trace is snipped for brevity)
      
      so what can happen is
      
         cpu 0                   	cpu 1
         user context			user context
      
      				take ins->scbs[index].lock without disabling interrupts
      
         get substream->self_group.lock (irqsafe)
         try to get ins->scbs[index].lock (spins)
      
      				interrupt happens
      				try to get substream->self_group.lock (spins)
      
      which is an obvious AB-BA deadlock
      
      fix is to just take the lock with _irqsafe

      [PATCH] mthca: initialize send and receive queue locks separately · a46f9484
      Zach Brown authored
      mthca: initialize send and receive queue locks separately
      
      lockdep identifies a lock by the call site of its initialization.  By
      initializing the send and receive queue locks in mthca_wq_init() we confuse
      lockdep.  It warns that that the ordered acquiry of both locks in
      mthca_modify_qp() is recursive acquiry of one lock:
      
        =============================================
        [ INFO: possible recursive locking detected ]
        ---------------------------------------------
        modprobe/1192 is trying to acquire lock:
         (&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca]
        but task is already holding lock:
         (&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca]
      
      Initializing the locks separately in mthca_alloc_qp_common() stops the
      warning and will let lockdep enforce proper ordering on paths that acquire
      both locks.

      [PATCH] Fix copying of pgdat array on each node for ia64 memory hotplug · dd8041f1
      Yasunori Goto authored
      I found a bug in memory hot-add code for ia64.
      
      IA64's code has copies of pgdat's array on each node to reduce memory
      access over crossing node.  This array is used by NODE_DATA() macro.  When
      new node is hot-added, this pgdat's array should be updated and copied on
      new node too.
      
      However, I used for_each_online_node() in scatter_node_data() to copy
      it. This meant its array is not copied on new node.
      Because initialization of structures for new node was halfway,
      so online_node_map couldn't be set at this time.
      
      To copy arrays on new node, I changed it to check value of pgdat_list[]
      which is source array of copies.  I tested this patch with my Memory Hotadd
      emulation on Tiger4.  This patch is for 2.6.17-git20.
