        concurrency related fixes and one PCI device removal fix for
        ACPI-based PCI hotplug (ACPIPHP), intel_pstate fix that should go into
        stable, three simple ACPI cleanups and a new entry for the ACPI video
        blacklist.
      
        Specifics:
      
         - Fix for a recent ACPI hotplug regression causing a NULL pointer
           dereference to occur while handling ACPI eject notifications for
           already ejected devices.  From Toshi Kani.
      
         - Four concurrency-related fixes for ACPIPHP.  Two of them add
           missing locking and the other two fix race conditions related to
           reference counting.
      
         - ACPIPHP fix to avoid NULL pointer dereferences during device
           removal involving Virtual Funcions.

      hwmon: (da9055) Remove use of regmap_irq_get_virq() · 4f545a4b
      Adam Thomson authored
      Remove use of regmap_irq_get_virq() in driver probe which was
      conflicting with use of platform_get_irq_byname().
      platform_get_irq_byname() already returns the VIRQ number due
      to MFD core translation so using regmap_irq_get_virq() on that
      returned value results in an incorrect IRQ being requested.
      The driver probes then fail because of this.

      mm: __set_page_dirty uses spin_lock_irqsave instead of spin_lock_irq · 227d53b3
      KOSAKI Motohiro authored
      To use spin_{un}lock_irq is dangerous if caller disabled interrupt.
      During aio buffer migration, we have a possibility to see the following
      call stack.
      
      aio_migratepage  [disable interrupt]
        migrate_page_copy
          clear_page_dirty_for_io
            set_page_dirty

                __set_page_dirty
                  spin_lock_irq
      
      This mean, current aio migration is a deadlockable.  spin_lock_irqsave
      is a safer alternative and we should use it.

      arch/x86/mm/numa.c: fix array index overflow when synchronizing nid to memblock.reserved. · 7bc35fdd
      Tang Chen authored
      The following path will cause array out of bound.
      
      memblock_add_region() will always set nid in memblock.reserved to
      MAX_NUMNODES.  In numa_register_memblks(), after we set all nid to
      correct valus in memblock.reserved, we called setup_node_data(), and
      used memblock_alloc_nid() to allocate memory, with nid set to
      MAX_NUMNODES.
      
      The nodemask_t type can be seen as a bit array.  And the index is 0 ~
      MAX_NUMNODES-1.
      
      After that, when we call node_set() in numa_clear_kernel_node_hotplug(),
      the nodemask_t got an index of value MAX_NUMNODES, which is out of [0 ~
      MAX_NUMNODES-1].
      
      See below:
      
      numa_init()
       |---> numa_register_memblks()
       |      |---> memblock_set_node(memory)		set correct nid in memblock.memory
       |      |---> memblock_set_node(reserved)	set correct nid in memblock.reserved
       |      |......
       |      |---> setup_node_data()
       |             |---> memblock_alloc_nid()	here, nid is set to MAX_NUMNODES (1024)
       |......
       |---> numa_clear_kernel_node_hotplug()
              |---> node_set()			here, we have an index 1024, and overflowed
      
      This patch moves nid setting to numa_clear_kernel_node_hotplug() to fix
      this problem.

      mm: __set_page_dirty_nobuffers() uses spin_lock_irqsave() instead of spin_lock_irq() · a85d9df1
      KOSAKI Motohiro authored
      During aio stress test, we observed the following lockdep warning.  This
      mean AIO+numa_balancing is currently deadlockable.
      
      The problem is, aio_migratepage disable interrupt, but
      __set_page_dirty_nobuffers unintentionally enable it again.
      
      Generally, all helper function should use spin_lock_irqsave() instead of
      spin_lock_irq() because they don't know caller at all.
      
         other info that might help us debug this:

      mm/swap: fix race on swap_info reuse between swapoff and swapon · f893ab41
      Weijie Yang authored
      swapoff clear swap_info's SWP_USED flag prematurely and free its
      resources after that.  A concurrent swapon will reuse this swap_info
      while its previous resources are not cleared completely.
      
      These late freed resources are:
       - p->percpu_cluster
       - swap_cgroup_ctrl[type]
       - block_device setting
       - inode->i_flags &= ~S_SWAPFILE
      
      This patch clears the SWP_USED flag after all its resources are freed,
      so that swapon can reuse this swap_info by alloc_swap_info() safely.

      swap: add a simple detector for inappropriate swapin readahead · 579f8290
      Shaohua Li authored
      This is a patch to improve swap readahead algorithm.  It's from Hugh and
      I slightly changed it.
      
      Hugh's original changelog:
      
      swapin readahead does a blind readahead, whether or not the swapin is
      sequential.  This may be ok on harddisk, because large reads have
      relatively small costs, and if the readahead pages are unneeded they can
      be reclaimed easily - though, what if their allocation forced reclaim of
      useful pages? But on SSD devices large reads are more expensive than
      small ones: if the readahead pages are unneeded, reading them in caused
      significant overhead.
      
      This patch adds very simplistic random read detection.  Stealing the
      PageReadahead technique from Konstantin Khlebnikov's patch, avoiding the
      vma/anon_vma sophistications of Shaohua Li's patch, swapin_nr_pages()
      simply looks at readahead's current success rate, and narrows or widens
      its readahead window accordingly.  There is little science to its
      heuristic: it's about as stupid as can be whilst remaining effective.
      
      The table below shows elapsed times (in centiseconds) when running a
      single repetitive swapping load across a 1000MB mapping in 900MB ram
      with 1GB swap (the harddisk tests had taken painfully too long when I
      used mem=500M, but SSD shows similar results for that).
      
      Vanilla is the 3.6-rc7 kernel on which I started; Shaohua denotes his
      Sep 3 patch in mmotm and linux-next; HughOld denotes my Oct 1 patch
      which Shaohua showed to be defective; HughNew this Nov 14 patch, with
      page_cluster as usual at default of 3 (8-page reads); HughPC4 this same
      patch with page_cluster 4 (16-page reads); HughPC0 with page_cluster 0
      (1-page reads: no readahead).
      
      HDD for swapping to harddisk, SSD for swapping to VertexII SSD.  Seq for
      sequential access to the mapping, cycling five times around; Rand for
      the same number of random touches.  Anon for a MAP_PRIVATE anon mapping;
      Shmem for a MAP_SHARED anon mapping, equivalent to tmpfs.
      
      One weakness of Shaohua's vma/anon_vma approach was that it did not
      optimize Shmem: seen below.  Konstantin's approach was perhaps mistuned,
      50% slower on Seq: did not compete and is not shown below.

      These tests are, of course, two extremes of a very simple case: under
      heavier mixed loads I've not yet observed any consistent improvement or
      degradation, and wider testing would be welcome.
      
      Shaohua Li:
      
      Test shows Vanilla is slightly better in sequential workload than Hugh's
      patch.  I observed with Hugh's patch sometimes the readahead size is
      shrinked too fast (from 8 to 1 immediately) in sequential workload if
      there is no hit.  And in such case, continuing doing readahead is good
      actually.
      
      I don't prepare a sophisticated algorithm for the sequential workload
      because so far we can't guarantee sequential accessed pages are swap out
      sequentially.  So I slightly change Hugh's heuristic - don't shrink
      readahead size too fast.
      
      Here is my test result (unit second, 3 runs average):
      	Vanilla		Hugh		New
      Seq	356		370		360
      Random	4525		2447		2444
      
      Attached graph is the swapin/swapout throughput I collected with 'vmstat
      2'.  The first part is running a random workload (till around 1200 of
      the x-axis) and the second part is running a sequential workload.
      swapin and swapout throughput are almost identical in steady state in
      both workloads.  These are expected behavior.  while in Vanilla, swapin
      is much bigger than swapout especially in random workload (because wrong
      readahead).

      ocfs2: free allocated clusters if error occurs after ocfs2_claim_clusters · fb951eb5
      Zongxun Wang authored
      Even if using the same jbd2 handle, we cannot rollback a transaction.
      So once some error occurs after successfully allocating clusters, the
      allocated clusters will never be used and it means they are lost.  For
      example, call ocfs2_claim_clusters successfully when expanding a file,
      but failed in ocfs2_insert_extent.  So we need free the allocated
      clusters if they are not used indeed.

      Dave Airlie authored
      the evergreen CS parser has allowed this for a while, just port
      the code to the r600 one.
      
      This is required before geom shaders can be made work.

      A couple of vmwgfx fixes together with missing bits of legacy device
      emulation to facilitate old user-space drivers on new devices.
      
      The shader emulation bits are a bit large, but since they mostly touch the
      new device code, regressions are unlikely. I figure the gain of having
      this from the start clearly outweighs the risc of adding these bits at
      this point.
