[GIT PULL] ACPI and power management fixes for 3.17-rc7

[Rafael J. Wysocki]

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.17-rc7

to receive ACPI and power management fixes for v3.17-rc7 (or
for the final v3.17 if there's no -rc7) with top-most commit
381e63da44301f49be5876d56a5da2434f132dff

 Merge branches 'pm-cpufreq' and 'pm-sleep'

on top of commit 0f33be009b89d2268e94194dc4fd01a7851b6d51

 Linux 3.17-rc6

These are regression fixes (ACPI hotplug, cpufreq, hibernation, ACPI
LPSS driver), fixes for stuff that never worked correctly (ACPI GPIO
support in some cases and a wrong sign of an error code in the ACPI
core in one place), and one blacklist item for ACPI backlight handling.

Specifics:

 - Revert of a recent hibernation core commit that introduced
   a NULL pointer dereference during resume for at least one user
   (Rafael J Wysocki).

 - Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable
   asynchronous PM callback execution for LPSS devices during system
   suspend/resume (introduced in 3.16) which turns out to break
   ordering expectations on some systems.  From Fu Zhonghui.

 - cpufreq core fix related to the handling of sysfs nodes during
   system suspend/resume that has been broken for intel_pstate
   since 3.15 from Lan Tianyu.

 - Restore the generation of "online" uevents for ACPI container
   devices that was removed in 3.14, but some user space utilities
   turn out to need them (Rafael J Wysocki).

 - The cpufreq core fails to release a lock in an error code path
   after changes made in 3.14.  Fix from Prarit Bhargava.

 - ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO
   operation regions (which means AML using GPIOs) work correctly
   in all cases from Bob Moore and Srinivas Pandruvada.

 - Fix for a wrong sign of the ACPI core's create_modalias() return
   value in case of an error from Mika Westerberg.

 - ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu.

Thanks!
