Date: Tue Sep 03 2013 - 07:34:11 EST

Hi Linus,

Please pull from the git repository at

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.12-rc1

to receive ACPI and power management updates for v3.12 with top-most commit
f41b83126cba53849dd2353476a7715613af648f

Merge branch 'pm-cpufreq'

on top of commit d8dfad3876e4386666b759da3c833d62fb8b2267

Linux 3.11-rc7

We have more ACPI commits than power management commits this time, mostly
due to the fact that I put some cpufreq cleanups on hold.

The headline feature of this pull request, in my personal view, is the
addition of Intel Thunderbolt support on systems that use ACPI for
signaling Thunderbolt hotplug events (they don't include Apple, because
Apple seems to have its own kind of secret way of doing this).
To make that work on all of our test machines we had to rework the
entire ACPI-based PCI hotplug (ACPIPHP) code and now it should cover
a few more cases in which it didn't work before.

Also worth mentioning is the change of cpufreq ondemand governor that
makes it choose target frequencies proportional to load. It simplifies
the code in question quite a bit and promises both to improve
performance and to reduce energy consumption slightly on systems using
that governor. It's been in linux-next pretty much since 3.11-rc1
and no one has reported any problems with it for that period, but that's
subtle stuff, so testing is obviously welcome.

In addition to that, the old and long deprecated /proc/acpi/event interface
is going away and no one seems to have any problems with that.

The rest is mostly cleanups and fixes all over and, interestingly enough,
we're removing more lines of code total than we're adding.

Specifics:

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 yours truly,
Mika Westerberg and Kirill A Shutemov.

2) ACPI core code cleanups and dock station support cleanups from
Jiang Liu and me.

3) Fixes for locking problems related to ACPI device hotplug.

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
myself.

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 suspend/hibernation 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.

Thanks!
