Linus Torvalds 4dedde7c7a ACPI and power management updates for 3.15-rc1
- Device PM QoS support for latency tolerance constraints on systems with
    hardware interfaces allowing such constraints to be specified.  That is
    necessary to prevent hardware-driven power management from becoming
    overly aggressive on some systems and to prevent power management
    features leading to excessive latencies from being used in some cases.
 
  - Consolidation of the handling of ACPI hotplug notifications for device
    objects.  This causes all device hotplug notifications to go through
    the root notify handler (that was executed for all of them anyway
    before) that propagates them to individual subsystems, if necessary,
    by executing callbacks provided by those subsystems (those callbacks
    are associated with struct acpi_device objects during device
    enumeration).  As a result, the code in question becomes both smaller
    in size and more straightforward and all of those changes should not
    affect users.
 
  - ACPICA update, including fixes related to the handling of _PRT in cases
    when it is broken and the addition of "Windows 2013" to the list of
    supported "features" for _OSI (which is necessary to support systems
    that work incorrectly or don't even boot without it).  Changes from
    Bob Moore and Lv Zheng.
 
  - Consolidation of ACPI _OST handling from Jiang Liu.
 
  - ACPI battery and AC fixes allowing unusual system configurations to
    be handled by that code from Alexander Mezin.
 
  - New device IDs for the ACPI LPSS driver from Chiau Ee Chew.
 
  - ACPI fan and thermal optimizations related to system suspend and resume
    from Aaron Lu.
 
  - Cleanups related to ACPI video from Jean Delvare.
 
  - Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan Tianyu,

Pull ACPI and power management updates from Rafael Wysocki:
 "The majority of this material spent some time in linux-next, some of
  it even several weeks.  There are a few relatively fresh commits in
  it, but they are mostly fixes and simple cleanups.

  ACPI took the lead this time, both in terms of the number of commits
  and the number of modified lines of code, cpufreq follows and there
  are a few changes in the PM core and in cpuidle too.

  A new feature that already got some LWN.net's attention is the device
  PM QoS extension allowing latency tolerance requirements to be
  propagated from leaf devices to their ancestors with hardware
  interfaces for specifying latency tolerance.  That should help systems
  with hardware-driven power management to avoid going too far with it
  in cases when there are latency tolerance constraints.

  There also are some significant changes in the ACPI core related to
  the way in which hotplug notifications are handled.  They affect PCI
  hotplug (ACPIPHP) and the ACPI dock station code too.  The bottom line
  is that all those notification now go through the root notify handler
  and are propagated to the interested subsystems by means of callbacks
  instead of having to install a notify handler for each device object
  that we can potentially get hotplug notifications for.

  In addition to that ACPICA will now advertise "Windows 2013"
  compatibility for _OSI, because some systems out there don't work
  correctly if that is not done (some of them don't even boot).

  On the system suspend side of things, all of the device suspend and
  resume callbacks, except for ->prepare() and ->complete(), are now
  going to be executed asynchronously as that turns out to speed up
  system suspend and resume on some platforms quite significantly and we
  have a few more optimizations in that area.

  Apart from that, there are some new device IDs and fixes and cleanups
  all over.  In particular, the system suspend and resume handling by
  cpufreq should be improved and the cpuidle menu governor should be a
  bit more robust now.

  Specifics:

   - Device PM QoS support for latency tolerance constraints on systems
     with hardware interfaces allowing such constraints to be specified.
     That is necessary to prevent hardware-driven power management from
     becoming overly aggressive on some systems and to prevent power
     management features leading to excessive latencies from being used
     in some cases.

   - Consolidation of the handling of ACPI hotplug notifications for
     device objects.  This causes all device hotplug notifications to go
     through the root notify handler (that was executed for all of them
     anyway before) that propagates them to individual subsystems, if
     necessary, by executing callbacks provided by those subsystems
     (those callbacks are associated with struct acpi_device objects
     during device enumeration).  As a result, the code in question
     becomes both smaller in size and more straightforward and all of
     those changes should not affect users.

   - ACPICA update, including fixes related to the handling of _PRT in
     cases when it is broken and the addition of "Windows 2013" to the
     list of supported "features" for _OSI (which is necessary to

     it).  Changes from Bob Moore and Lv Zheng.

     Kumar.

     Karafotis, Saravana Kannan, Rashika Kheria, Joe Perches.
