Linus Torvalds 09da8dfa98 ACPI and power management updates for 3.14-rc1
- 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.

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

************************************************************

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
    http://sourceforge.net/project/showfiles.php?group_id=387
    http://dri.sourceforge.net/doc/
