      [ARM] Update show_regs/oops register format · 154c772e
      Russell King authored
      Add the kernel release and version information to the output of
      show_regs/oops.  Add the CPU PSR register.  Avoid using printk
      to output partial lines; always output a complete line.
      
      Re-combine the "Control" and "Table + DAC" lines after nommu
      separated them; we don't want to waste vertical screen space
      needlessly.

      mm: Fix memory/cpu hotplug section mismatch and oops. · d09c6b80
      Paul Mundt authored
      When building with memory hotplug enabled and cpu hotplug disabled, we
      end up with the following section mismatch:
      
      WARNING: mm/built-in.o(.text+0x4e58): Section mismatch: reference to
      .init.text: (between 'free_area_init_node' and '__build_all_zonelists')
      
      This happens as a result of:
      
              -> free_area_init_node()
                -> free_area_init_core()
                  -> zone_pcp_init() <-- all __meminit up to this point
                    -> zone_batchsize() <-- marked as __cpuinit                     fo
      
      This happens because CONFIG_HOTPLUG_CPU=n sets __cpuinit to __init, but
      CONFIG_MEMORY_HOTPLUG=y unsets __meminit.
      
      Changing zone_batchsize() to __devinit fixes this.
      
      __devinit is the only thing that is common between CONFIG_HOTPLUG_CPU=y and
      CONFIG_MEMORY_HOTPLUG=y. In the long run, perhaps this should be moved to
      another section identifier completely. Without this, memory hot-add
      of offline nodes (via hotadd_new_pgdat()) will oops if CPU hotplug is
      not also enabled.

      block: always requeue !fs requests at the front · bc90ba09
      Tejun Heo authored
      SCSI marks internal commands with REQ_PREEMPT and push it at the front
      of the request queue using blk_execute_rq().  When entering suspended
      or frozen state, SCSI devices are quiesced using
      scsi_device_quiesce().  In quiesced state, only REQ_PREEMPT requests
      are processed.  This is how SCSI blocks other requests out while
      suspending and resuming.  As all internal commands are pushed at the
      front of the queue, this usually works.
      
      Unfortunately, this interacts badly with ordered requeueing.  To
      preserve request order on requeueing (due to busy device, active EH or
      other failures), requests are sorted according to ordered sequence on
      requeue if IO barrier is in progress.
      
      The following sequence deadlocks.
      
      1. IO barrier sequence issues.
      
      2. Suspend requested.  Queue is quiesced with part or all of IO
         barrier sequence at the front.
      
      3. During suspending or resuming, SCSI issues internal command which
         gets deferred and requeued for some reason.  As the command is
         issued after the IO barrier in #1, ordered requeueing code puts the
         request after IO barrier sequence.
      
      4. The device is ready to process requests again but still is in
         quiesced state and the first request of the queue isn't
         REQ_PREEMPT, so command processing is deadlocked -
         suspending/resuming waits for the issued request to complete while
         the request can't be processed till device is put back into
         running state by resuming.
      
      This can be fixed by always putting !fs requests at the front when
      requeueing.
      
      The following thread reports this deadlock.
