Pull more ACPI and power management fixes and updates from Rafael Wysocki:
 "This is PM and ACPI material that has emerged over the last two weeks
  and one fix for a CPU hotplug regression introduced by the recent CPU
  hotplug notifiers registration series.

  Included are intel_idle and turbostat updates from Len Brown (these
  have been in linux-next for quite some time), a new cpufreq driver for
  powernv (that might spend some more time in linux-next, but BenH was
  asking me so nicely to push it for 3.15 that I couldn't resist), some
  cpufreq fixes and cleanups (including fixes for some silly breakage in
  a couple of cpufreq drivers introduced during the 3.14 cycle),
  assorted ACPI cleanups, wakeup framework documentation fixes, a new
  sysfs attribute for cpuidle and a new command line argument for power
  domains diagnostics.

  Specifics:

   - Fix for a recently introduced CPU hotplug regression in ARM KVM
     from Ming Lei.

   - Fixes for breakage in the at32ap, loongson2_cpufreq, and unicore32
     cpufreq drivers introduced during the 3.14 cycle (-stable material)
     from Chen Gang and Viresh Kumar.

   - New powernv cpufreq driver from Vaidyanathan Srinivasan, with bits
     from Gautham R Shenoy and Srivatsa S Bhat.

   - Exynos cpufreq driver fix preventing it from being included into
     multiplatform builds that aren't supported by it from Sachin Kamat.

   - cpufreq cleanups related to the usage of the driver_data field in
     struct cpufreq_frequency_table from Viresh Kumar.

   - cpufreq ppc driver cleanup from Sachin Kamat.

   - Intel BayTrail support for intel_idle and ACPI idle from Len Brown.

   - Intel CPU model 54 (Atom N2000 series) support for intel_idle from
     Jan Kiszka.

   - intel_idle fix for Intel Ivy Town residency targets from Len Brown.

   - turbostat updates (Intel Broadwell support and output cleanups)
     from Len Brown.

   - New cpuidle sysfs attribute for exporting C-states' target
     residency information to user space from Daniel Lezcano.

   - New kernel command line argument to prevent power domains enabled
     by the bootloader from being turned off even if they are not in use
     (for diagnostics purposes) from Tushar Behera.

   - Fixes for wakeup sysfs attributes documentation from Geert
     Uytterhoeven.

   - New ACPI video blacklist entry for ThinkPad Helix from Stephen
     Chandler Paul.

   - Assorted ACPI cleanups and a Kconfig help update from Jonghwan
     Choi, Zhihui Zhang, Hanjun Guo"
