    Linus Torvalds 提交于
    Pull ACPI and power management updates from Rafael Wysocki:
    
     1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
        of Intel Thunderbolt support on systems that use ACPI for signalling
        Thunderbolt hotplug events.  This also should make ACPIPHP work in
        some cases in which it was known to have problems.  From
        Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.
    
     2) ACPI core code cleanups and dock station support cleanups from
        Jiang Liu and Rafael J Wysocki.
    
     3) Fixes for locking problems related to ACPI device hotplug from
        Rafael J Wysocki.
    
     4) ACPICA update to version 20130725 includig fixes, cleanups, support
        for more than 256 GPEs per GPE block and a change to make the ACPI
        PM Timer optional (we've seen systems without the PM Timer in the
        field already).  One of the fixes, related to the DeRefOf operator,
        is necessary to prevent some Windows 8 oriented AML from causing
        problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.
    
     5) Removal of the old and long deprecated /proc/acpi/event interface
        and related driver changes from Thomas Renninger.
    
     6) ACPI and Xen changes to make the reduced hardware sleep work with
        the latter from Ben Guthro.
    
     7) ACPI video driver cleanups and a blacklist of systems that should
        not tell the BIOS that they are compatible with Windows 8 (or ACPI
        backlight and possibly other things will not work on them).  From
        Felipe Contreras.
    
     8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,
        Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
        Toshi Kani, and Wei Yongjun.
    
     9) cpufreq ondemand governor target frequency selection change to
        reduce oscillations between min and max frequencies (essentially,
        it causes the governor to choose target frequencies proportional
        to load) from Stratos Karafotis.
    
    10) cpufreq fixes allowing sysfs attributes file permissions to be
        preserved over suspend/resume cycles Srivatsa S Bhat.
    
    11) Removal of Device Tree parsing for CPU device nodes from multiple
        cpufreq drivers that required some changes related to
        of_get_cpu_node() to be made in a few architectures and in the
        driver core.  From Sudeep KarkadaNagesha.
    
    12) cpufreq core fixes and cleanups related to mutual exclusion and
        driver module references from Viresh Kumar, Lukasz Majewski and
        Rafael J Wysocki.
    
    13) Assorted cpufreq fixes and cleanups from Amit Daniel Kachhap,
        Bartlomiej Zolnierkiewicz, Hanjun Guo, Jingoo Han, Joseph Lo,
        Julia Lawall, Li Zhong, Mark Brown, Sascha Hauer, Stephen Boyd,
        Stratos Karafotis, and Viresh Kumar.
    
    14) Fixes to prevent race conditions in coupled cpuidle from happening
        from Colin Cross.
    
    15) cpuidle core fixes and cleanups from Daniel Lezcano and
        Tuukka Tikkanen.
    
    16) Assorted cpuidle fixes and cleanups from Daniel Lezcano,
        Geert Uytterhoeven, Jingoo Han, Julia Lawall, Linus Walleij,
        and Sahara.
    
    17) System sleep tracing changes from Todd E Brandt and Shuah Khan.
    
    18) PNP subsystem conversion to using struct dev_pm_ops for power
        management from Shuah Khan.
