ACPI and power management fixes for 3.15-rc3

Browse source 
- Fix for broken ACPI notifications on some systems caused by
    a recent ACPI hotplug commit that blocked the propagation of
    unknown type notifications to device drivers inadvertently.
 
  - intel_idle fix to make the IvyTown C-states handling (added
    recently) work as intended which now is broken due to missing
    braces.  From Christoph Jaeger.
 
  - ACPICA fix to make it allocate buffers of the right sizes for
    the Generic Serial Bus operation region access.  From Lv Zheng.
 
  - PM core fix unblocking cpuidle before entering the "freeze"
    sleep state which causes that state to be able to actually save
    more energy than runtime idle.
 
  - Configuration and build fixes for the highbank and powernv
    cpufreq drivers from Kefeng Wang and Srivatsa S Bhat.
 
  - Coccinelle warning fix related to error pointers for the
    unicore32 cpufreq driver from Duan Jiong.
 
  - Integer overflow fix for the ppc-corenet cpufreq driver from
    Geert Uytterhoeven.
 
  - Workaround for BIOSes that don't report the entire Intel MCH
    area in their ACPI tables from Bjorn Helgaas.
 
  - ACPI tools Makefile fix and cleanup from Thomas Renninger.

Pull ACPI and power management fixes from Rafael Wysocki:
 "These include a fix for a recent ACPI regression related to device
  notifications, intel_idle fix related to IvyTown support, fix for a
  buffer size issue in ACPICA, PM core fix related to the "freeze" sleep
  state, four fixes for various types of breakage in cpufreq drivers, a
  PNP workaround for a wrong memory region size in ACPI tables, and a
  fix and cleanup for the ACPI tools Makefile.

  Specifics:

   - Fix for broken ACPI notifications on some systems caused by a
     recent ACPI hotplug commit that blocked the propagation of unknown
     type notifications to device drivers inadvertently.

   - intel_idle fix to make the IvyTown C-states handling (added
     recently) work as intended which now is broken due to missing
     braces.  From Christoph Jaeger.

   - ACPICA fix to make it allocate buffers of the right sizes for the
     Generic Serial Bus operation region access.  From Lv Zheng.

   - PM core fix unblocking cpuidle before entering the "freeze" sleep
     state which causes that state to be able to actually save more
     energy than runtime idle.

   - Configuration and build fixes for the highbank and powernv cpufreq
     drivers from Kefeng Wang and Srivatsa S Bhat.

   - Coccinelle warning fix related to error pointers for the unicore32
     cpufreq driver from Duan Jiong.

   - Integer overflow fix for the ppc-corenet cpufreq driver from Geert
     Uytterhoeven.

   - Workaround for BIOSes that don't report the entire Intel MCH area
     in their ACPI tables from Bjorn Helgaas.
