 ACPI and power management fixes for 3.15-rc4
 
  - There are two bugs in the ACPI PNP core that cause errors to
    be returned if optional ACPI methods are not present.  After
    an ACPI core change made in 3.14 one of those errors leads
    to serial port suspend failures on some systems.  Fix from
    Rafael J Wysocki.
 
  - A recently added PNP quirk related to Intel chipsets intorduced
    a build error in unusual configurations (PNP without PCI).  Fix
    from Bjorn Helgaas.
 
  - An ACPI EC workaround related to system suspend on Samsung machines
    added in 3.14 introduced a race causing some valid EC events to be
    discarded.  Fix from Kieran Clancy.
 
  - The acpi-cpufreq driver fails to load on some systems after a 3.14
    commit related to APIC ID parsing that overlooked one corner case.
    Fix from Lan Tianyu.
 
  - Fix for a recently introduced build problem in the ppc-corenet
    cpufreq driver from Tim Gardner.
 
  - A recent cpufreq core change to ensure serialization of frequency
    transitions for drivers with a ->target_index() callback overlooked
    the fact that some of those drivers had been doing operations
    introduced by it into the core already by themselves.  That resulted
    in a mess in which the core and the drivers try to do the same thing
    and block each other which leads to deadlocks.  Fixes for the
    powernow-k7, powernow-k6, and longhaul cpufreq drivers from
    Srivatsa S Bhat.
 
  - Fix for a computational error in the powernow-k6 cpufreq driver
    from Srivatsa S Bhat.

Pull ACPI and power management fixes from Rafael Wysocki:
 "A bunch of regression fixes this time.  They fix two regressions in
  the PNP subsystem, one in the ACPI processor driver and one in the
  ACPI EC driver, four cpufreq driver regressions and an unrelated bug
  in one of the drivers.  The regressions are recent or introduced in
  3.14.

  Specifics:

   - There are two bugs in the ACPI PNP core that cause errors to be
     returned if optional ACPI methods are not present.  After an ACPI
     core change made in 3.14 one of those errors leads to serial port
     suspend failures on some systems.  Fix from Rafael J Wysocki.

   - A recently added PNP quirk related to Intel chipsets intorduced a
     build error in unusual configurations (PNP without PCI).  Fix from
     Bjorn Helgaas.

   - An ACPI EC workaround related to system suspend on Samsung machines
     added in 3.14 introduced a race causing some valid EC events to be
     discarded.  Fix from Kieran Clancy.

   - The acpi-cpufreq driver fails to load on some systems after a 3.14
     commit related to APIC ID parsing that overlooked one corner case.
