      Pull ACPI and power management fixes from Rafael Wysocki:
      
       - ACPI-based memory hotplug stopped working after a recent change,
         because it's not possible to associate sufficiently many "physical"
         devices with one ACPI device object due to an artificial limit.  Fix
         from Rafael J Wysocki removes that limit and makes memory hotplug
         work again.
      
       - A change made in 3.9 uncovered a bug in the ACPI processor driver
         preventing NUMA nodes from being put offline due to an ordering
         issue.  Fix from Yasuaki Ishimatsu changes the ordering to make
         things work again.
      
       - One of the recent ACPI video commits (that hasn't been reverted so
         far) uncovered a bug in the code handling quirky BIOSes that caused
         some Asus machines to boot with backlight completely off which made
         it quite difficult to use them afterward.  Fix from Felipe Contreras
         improves the quirk to cover this particular case correctly.
      
       - A cpufreq user space interface change made in 3.10 inadvertently
         renamed the ignore_nice_load sysfs attribute to ignore_nice which
         resulted in some confusion.  Fix from Viresh Kumar changes the name
         back to ignore_nice_load.
      
       - An initialization ordering change made in 3.9 broke cpufreq on
         loongson2 boards.  Fix from Aaro Koskinen restores the correct
         initialization ordering there.
      
       - Fix breakage resulting from a mistake made in 3.9 and causing the
         detection of some graphics adapters (that were detected correctly
         before) to fail.  There are two objects representing the same PCIe
         port in the affected systems' ACPI tables and both appear as
         "enabled" and we are expected to guess which one to use.  We used to
         choose the right one before by pure luck, but when we tried to
         address another similar corner case, the luck went away.  This time
         we try to make our guessing a bit more educated which is reported to
         work on those systems.
      
       - The /proc/acpi/wakeup interface code is missing some locking which
         may lead to breakage if that file is written or read during hotplug
         of wakeup devices.  That should be rare but still possible, so it's
         better to start using the appropriate locking there.

      dlm: kill the unnecessary and wrong device_close()->recalc_sigpending() · 201d3dfa
      Oleg Nesterov authored
      device_close()->recalc_sigpending() is not needed, sigprocmask() takes
      care of TIF_SIGPENDING correctly.
      
      And without ->siglock it is racy and wrong, it can wrongly clear
      TIF_SIGPENDING and miss a signal.
      
      But even with this patch device_close() is still buggy:
      
        1. sigprocmask() should not be used, we have set_task_blocked(),
           but this is minor.
      
        2. We should never block SIGKILL or SIGSTOP, and this is what
           the code tries to do.
      
        3. This can't protect against SIGKILL or SIGSTOP anyway. Another
           thread can do signal_wake_up(), say, do_signal_stop() or
           complete_signal() or debugger.
      
        4. sigprocmask(SIG_BLOCK, allsigs) doesn't necessarily clears
           TIF_SIGPENDING, say, freezing() or ->jobctl.
      
        5. device_write() looks equally wrong by the same reason.
      
      Looks like, this tries to protect some wait_event_interruptible() logic
      from signals, it should be turned into uninterruptible wait.  Or we need
      to implement something like signals_stop/start for such a use-case.

      Revert "HID: hid-logitech-dj: querying_devices was never set" · 8e5654ce
      Jiri Kosina authored
      This reverts commit 407a2c2a.
      
      Explanation provided by Benjamin Tissoires:
      
      Commit "HID: hid-logitech-dj, querying_devices was never set" activate
      a flag which guarantees that we do not ask the receiver for too many
      enumeration. When the flag is set, each following enumeration call is
      discarded (the usb request is not forwarded to the receiver). The flag
      is then released when the driver receive a pairing information event,
      which normally follows the enumeration request.
      However, the USB3 bug makes the driver think the enumeration request
      has been forwarded to the receiver. However, it is actually not the
      case because the USB stack returns -EPIPE. So, when a new unknown
      device appears, the workaround consisting in asking for a new
      enumeration is not working anymore: this new enumeration is discarded
      because of the flag, which is never reset.
      
      A solution could be to trigger a timeout before releasing it, but for
      now, let's just revert the patch.
