      Pull qxl drm fixes from Dave Airlie:
       "Okay as I warned, the qxl driver was running a bit free and loose with
        its ttm object reservations and the new lockdep enabled reservation
        tracking shone a bright light into it, it also with the new
        reservations mutexes hits a possible deadlock during boot.
      
        The first patch is a real fix to render the console correctly as the
        driver used to just drop irq renderering as too hard, this also fixes
        a sleeping while atomic warning.
      
        The other two patches are the big ugly ones that redo how the driver
        allocates objects and reserves them and makes things all work
        properly, I've tested this in a VM, and compared to the current code
        which hits a lockdep warning and the sleep while atomic warning before
        failing.
      
        So sorry this is coming in late, I should have tested qxl before
        merging the mutex code, but I'd rather just fix qxl with this than
        revert the reservations code at this point"

      Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8" · 8e5c2b77
      Rafael J. Wysocki authored
      We attempted to address a regression introduced by commit a57f7f91
      (ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
      ACPI video backlight support doesn't work on a number of systems,
      because the relevant AML methods in the ACPI tables in their BIOSes
      become useless after the BIOS has been told that the OS is compatible
      with Windows 8.  That problem is tracked by the bug entry at:
      
      https://bugzilla.kernel.org/show_bug.cgi?id=51231
      
      Commit 8c5bd7ad (ACPI / video / i915: No ACPI backlight if firmware
      expects Windows 8) introduced for this purpose essentially prevented
      the ACPI backlight support from being used if the BIOS had been told
      that the OS was compatible with Windows 8 and the i915 driver was
      loaded, in which case the backlight would always be handled by i915.
      Unfortunately, however, that turned out to cause problems with
      backlight to appear on multiple systems with symptoms indicating that
      i915 was unable to control the backlight on those systems as
      expected.
      
      For this reason, revert commit 8c5bd7ad, but leave the function
      acpi_video_backlight_quirks() introduced by it, because another
      commit on top of it uses that function.

      tracing: Remove locking trace_types_lock from tracing_reset_all_online_cpus() · 09d8091c
      Steven Rostedt (Red Hat) authored
      Commit a8227415 "tracing: Protect ftrace_trace_arrays list in trace_events.c"
      added taking the trace_types_lock mutex in trace_events.c as there were
      several locations that needed it for protection. Unfortunately, it also
      encapsulated a call to tracing_reset_all_online_cpus() which also takes
      the trace_types_lock, causing a deadlock.
      
      This happens when a module has tracepoints and has been traced. When the
      module is removed, the trace events module notifier will grab the
      trace_types_lock, do a bunch of clean ups, and also clears the buffer
      by calling tracing_reset_all_online_cpus. This doesn't happen often
      which explains why it wasn't caught right away.
      
      Commit a8227415 was marked for stable, which means this must be
      sent to stable too.

      mfd: max8925: fix dt code for backlight · 515c0967
      Olof Johansson authored
      The device-tree enablement for max8925 has several problems, but besides
      the bindings being wrong (and not having seen review) there's also some
      bad coding practices on how to fill in the platform_data from device tree.
      
      I came across this since it causes a warning when compiling
      mmp2_defconfig, and instead of doing the minimal fix to silence the
      warning, I restructured the code a bit.
      
      This silences the warning:
      drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
      drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]
      
      Note that the bindings themselves need to be revisited too, but that will
      affect more than just the backlight driver and is best done separately;
      this just fixes the bad code for the backlight driver.

      xhci: Bug fixes, now with more tags!
      
      Hi Greg,
      
      Here's five bug fixes for 3.12.
      
      The three patches are marked for stable.  Two fix NULL pointer dereferences.
      The third marked for stable suppresses some serious log spam from unnecessary
      xHCI driver warnings, whenever an isochronous short packet happens on an xHCI
      1.0 host.
      
      The other two patches fix build warnings.

      xfs: di_flushiter considered harmful · e1b4271a
      Dave Chinner authored
      When we made all inode updates transactional, we no longer needed
      the log recovery detection for inodes being newer on disk than the
      transaction being replayed - it was redundant as replay of the log
      would always result in the latest version of the inode would be on
      disk. It was redundant, but left in place because it wasn't
      considered to be a problem.
      
      However, with the new "don't read inodes on create" optimisation,
      flushiter has come back to bite us. Essentially, the optimisation
      made always initialises flushiter to zero in the create transaction,
      and so if we then crash and run recovery and the inode already on
      disk has a non-zero flushiter it will skip recovery of that inode.
      As a result, log recovery does the wrong thing and we end up with a
      corrupt filesystem.
      
      Because we have to support old kernel to new kernel upgrades, we
      can't just get rid of the flushiter support in log recovery as we
      might be upgrading from a kernel that doesn't have fully transactional
      inode updates.  Unfortunately, for v4 superblocks there is no way to
      guarantee that log recovery knows about this fact.
      
      We cannot add a new inode format flag to say it's a "special inode
      create" because it won't be understood by older kernels and so
      recovery could do the wrong thing on downgrade. We cannot specially
      detect the combination of zero mode/non-zero flushiter on disk to
      non-zero mode, zero flushiter in the log item during recovery
      because wrapping of the flushiter can result in false detection.
      
      Hence that makes this "don't use flushiter" optimisation limited to
      a disk format that guarantees that we don't need it. And that means
      the only fix here is to limit the "no read IO on create"
      optimisation to version 5 superblocks....

      usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0 · 07f3cb7c
      George Cherian authored
      Xhci controllers with hci_version > 0.96 gives spurious success
      events on short packet completion. During webcam capture the
      "ERROR Transfer event TRB DMA ptr not part of current TD" was observed.
      The same application works fine with synopsis controllers hci_version 0.96.
      The same issue is seen with Intel Pantherpoint xhci controller. So enabling
      this quirk in xhci_gen_setup if controller verion is greater than 0.96.
      For xhci-pci move the quirk to much generic place xhci_gen_setup.
      
      Note from Sarah:
      
      The xHCI 1.0 spec changed how hardware handles short packets.  The HW
      will notify SW of the TRB where the short packet occurred, and it will
      also give a successful status for the last TRB in a TD (the one with the
      IOC flag set).  On the second successful status, that warning will be
      triggered in the driver.
      
      Software is now supposed to not assume the TD is not completed until it
      gets that last successful status.  That means we have a slight race
      condition, although it should have little practical impact.  This patch
      papers over that issue.
      
      It's on my long-term to-do list to fix this race condition, but it is a
      much more involved patch that will probably be too big for stable.  This
      patch is needed for stable to avoid serious log spam.
      
      This patch should be backported to kernels as old as 3.0, that
      contain the commit ad808333 "Intel xhci:
      Ignore spurious successful event."
      
      The patch will have to be modified for kernels older than 3.2, since
      that kernel added the xhci_gen_setup function for xhci platform devices.
      The correct conflict resolution for kernels older than 3.2 is to set
      XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts.

      xhci: Avoid NULL pointer deref when host dies. · 203a8661
      Sarah Sharp authored
      When the host controller fails to respond to an Enable Slot command, and
      the host fails to respond to the register write to abort the command
      ring, the xHCI driver will assume the host is dead, and call
      usb_hc_died().
      
      The USB device's slot_id is still set to zero, and the pointer stored at
      xhci->devs[0] will always be NULL.  The call to xhci_check_args in
      xhci_free_dev should have caught the NULL virt_dev pointer.
      
      However, xhci_free_dev is designed to free the xhci_virt_device
      structures, even if the host is dead, so that we don't leak kernel
      memory.  xhci_free_dev checks the return value from the generic
      xhci_check_args function.  If the return value is -ENODEV, it carries on
      trying to free the virtual device.
      
      The issue is that xhci_check_args looks at the host controller state
      before it looks at the xhci_virt_device pointer.  It will return -ENIVAL
      because the host is dead, and xhci_free_dev will ignore the return
      value, and happily dereference the NULL xhci_virt_device pointer.
      
      The fix is to make sure that xhci_check_args checks the xhci_virt_device
      pointer before it checks the host state.
      
      See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for
      further details.  This patch doesn't solve the underlying issue, but
      will ensure we don't see any more NULL pointer dereferences because of
      the issue.
      
      This patch should be backported to kernels as old as 3.1, that
      contain the commit 7bd89b40 "xhci: Don't
