[GIT PULL] ACPI and power management fixes for v3.16-rc5

[Rafael J. Wysocki]

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.16-rc5

to receive ACPI and power management fixes for v3.16-rc5
with top-most commit 2091044299e9bc3340d845301b13bd92d6c10993

 Merge branch 'pm-cpufreq'

on top of commit cd3de83f147601356395b57a8673e9c5ff1e59d1

 Linux 3.16-rc4

These are a few regression fixes for ACPI device enumeration and
resources management, intel_pstate and cpufreq, a revert of an
ACPI commit removing user space interfaces in /proc that we
incorrectly thought were not used any more, fixes for some
long-standing concurrency issues in the ACPI EC driver, two ACPI
battery driver fixes, stable-candidate fixes for intel_pstate, an
ACPI-related fix for i915 and two new ACPI video blacklist entries
for Win8-oriented BIOSes.

Specifics:

 - Missing device ID for ACPI enumeration of PNP devices that we
   overlooked during the recent rework of that code from Zhang Rui.

 - Fix for a problem introduced during the 3.14 cycle in the ACPI
   device resources management code and causing it to reject all
   resources of length 0 although some of them are actually valid
   which affects serial ports detection on a number of systems.
   From Andy Whitcroft.

 - intel_pstate fix for a boot problem on some BayTrail-based
   systems introduced by a previous fix related to that platform
   during the 3.13 cycle from Dirk Brandewie.

 - Revert of a 3.13 commit that removed the ACPI AC /proc interface
   which turns out to be still needed by some old utilities (kpowersave
   from kde 3.5.10 in particular) from Lan Tianyu.

 - cpufreq build fix for the davinci ARM platform from Prabhakar Lad
   (the breakage was introduced during the 3.10 cycle).

 - ACPI-related i915 fix preventing firmware on some Thinkpad laptops
   from setting backlight levels incorrectly during AC plug/unplug.
   From Aaron Lu.

 - Fixes for two nasty race conditions in the ACPI embedded controller
   driver that may be responsible for a number of past bug reports
   related to the EC from Lv Zhang and a fix for two memory leaks in
   error code paths in that driver from Colin Ian King.

 - Fixes for a couple of corner-case issues in the intel_pstate
   driver (all candidates for -stable) from Dirk Brandewie and
   Vincent Minet.

 - Fixes for two corner-case issues in the ACPI battery driver
   from Josef Gajdusek and Lan Tianyu.

 - Two new ACPI video blacklist entries for Acer TravelMate B113
   and Dell Inspiron 5737 from Edward Lin and Martin Kepplinger.

Thanks!
