Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

   - On top of the above, new sysfs attribute for ACPI device objects
     allowing user space to check device status by triggering the
     execution of _STA for its ACPI object.  From Srinivas Pandruvada.

   - ACPI core hotplug changes reducing code duplication, integrating
     the PCI root hotplug with the core and reworking container hotplug.

   - ACPI core simplifications making it use ACPI_COMPANION() in the
     code "glueing" ACPI device objects to "physical" devices.

   - ACPICA update to upstream version 20131218.  This adds support for
     the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves
     debug facilities.  From Bob Moore, Lv Zheng and Betty Dall.

   - Init code change to carry out the early ACPI initialization
     earlier.  That should allow us to use ACPI during the timekeeping
     initialization and possibly to simplify the EFI initialization too.
     From Chun-Yi Lee.

   - Clenups of the inclusions of ACPI headers in many places all over
     from Lv Zheng and Rashika Kheria (work in progress).

   - New helper for ACPI _DSM execution and rework of the code in
     drivers that uses _DSM to execute it via the new helper.  From
     Jiang Liu.

   - New Win8 OSI blacklist entries from Takashi Iwai.

   - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun
     Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava,
     Rashika Kheria, Tang Chen, Zhang Rui.

   - intel_pstate driver updates, including proper Baytrail support,
     from Dirk Brandewie and intel_pstate documentation from Ramkumar
     Ramachandra.

   - Generic CPU boost ("turbo") support for cpufreq from Lukasz
     Majewski.

   - powernow-k6 cpufreq driver fixes from Mikulas Patocka.

   - cpufreq core fixes and cleanups from Viresh Kumar, Jane Li, Mark
     Brown.

   - Assorted cpufreq drivers fixes and cleanups from Anson Huang, John
     Tobias, Paul Bolle, Paul Walmsley, Sachin Kamat, Shawn Guo, Viresh
     Kumar.

   - cpuidle cleanups from Bartlomiej Zolnierkiewicz.

   - Support for hibernation APM events from Bin Shi.

   - Hibernation fix to avoid bringing up nonboot CPUs with ACPI EC
     disabled during thaw transitions from Bjørn Mork.

   - PM core fixes and cleanups from Ben Dooks, Leonardo Potenza, Ulf
     Hansson.

   - PNP subsystem fixes and cleanups from Dmitry Torokhov, Levente
     Kurusa, Rashika Kheria.

   - New tool for profiling system suspend from Todd E Brandt and a
     cpupower tool cleanup from One Thousand Gnomes"
