Subject: [GIT PULL] More ACPI and power management updates for 3.17-rc1

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.17-rc1-2

to receive more ACPI and power management updates for v3.17-rc1 with
top-most commit af5b7e84d022fdea373038d831bb4ca2c0e82108

 Merge branch 'pm-tools'

on top of commit 7725131982477bffff8ffdea143434dcc69f5d90

 Merge tag 'pm+acpi-3.17-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/
linux-pm

These are a couple of regression fixes, cpuidle menu governor
optimizations, fixes for ACPI proccessor and battery drivers,
hibernation fix to avoid problems related to the e820 memory map,
fixes for a few cpufreq drivers and a new version of the suspend
profiling tool analyze_suspend.py.

Specifics:

 - Fix for an ACPI-based device hotplug regression introduced in 3.14
   that causes a kernel panic to trigger when memory hot-remove is
   attempted with CONFIG_ACPI_HOTPLUG_MEMORY unset from Tang Chen.

 - Fix for a cpufreq regression introduced in 3.16 that triggers a
   "sleeping function called from invalid context" bug in
   dev_pm_opp_init_cpufreq_table() from Stephen Boyd.

 - ACPI battery driver fix for a warning message added in 3.16 that
   prints silly stuff sometimes from Mariusz Ceier.

 - Hibernation fix for safer handling of mismatches in the 820 memory
   map between the configurations during image creation and during
   the subsequent restore from Chun-Yi Lee.

 - ACPI processor driver fix to handle CPU hotplug notifications
   correctly during system suspend/resume from Lan Tianyu.

 - Series of four cpuidle menu governor cleanups that also should
   speed it up a bit from Mel Gorman.

 - Fixes for the speedstep-smi, integrator, cpu0 and arm_big_little
   cpufreq drivers from Hans Wennborg, Himangi Saraogi, Markus Pargmann
   and Uwe Kleine-König.

 - Version 3.0 of the analyze_suspend.py suspend profiling tool
   from Todd E Brandt.

Thanks!
