Pull late power management and ACPI fixes from Rafael Wysocki:
 "Sorry about the timing of this, but ACPI-based docking stations with
  PCI devices on them and ATA bays would be hardly usable with 3.10
  without it.  We've been working on these fixes for the last couple of
  weeks and everyone involved appears to be reasonably comfortable with
  them now.

  The PM part is one fix for a cpufreq regression introduced recently

   - Fix for an ACPI dock regression introduced by the recent rework of
     the ACPI-based PCI hotplug code (acpiphp) that caused it to be
     initialized before the ACPI dock driver, which is incorrect (ACPI
     dock has to be initialized before acpiphp so that acpiphp can
     register PCI devices on docking stations with it for PCI hotplug on
     re-dock to work).  From Jiang Liu.

   - Fix for PCI resources allocation in the ACPI-based PCI hotplug code
     (acpiphp) that makes it use the same PCI resources assignment rules
     during runtime hotplug that are used during boot (the BIOS' choices
     are now respected in both cases).  This prevents PCI resource
     allocation failures during hotplug from happening in some cases.
     From Jiang Liu.

   - Fix for ordering and synchronization issues during hot-removal of
     PCI devices on docking stations.  It makes the ACPI dock code carry
     out the PCI devices removal synchronously during undock instead of
     spawning a separate asynchronous work item to remove each of them
     without even bothering to wait for all those work items to
     complete.  The hot-addition part is changed analogously.

   - Fix for a regression (introduced a few releases ago) that removed
     the code to register a hotplug notificaion handler for for ATA
     ports/devices inadvertently which prevented ATA bays hotplug from
     working.  The missing code is added back with some improvements.
     From Aaron Lu.

   - Fix for a recent cpufreq regression causing a NULL pointer
     dereference to trigger in od_set_powersave_bias() in some
     situations from Jacob Shin"
