Linus Torvalds b890eb4ecc ACPI and power management fixes and cleanups for 3.14-rc1
- ACPI device hotplug fix preventing ACPI drivers from binding to device
    objects that acpi_bus_trim() has been called for and the devices
    represented by them may not be operational.
 
  - Recent cpufreq changes related to the "boost" (turbo) feature broke
    the acpi-cpufreq error code path causing a NULL pointer dereference
    to occur on some systems.  Fix from Konrad Rzeszutek Wilk.
 
  - The log level of a CPU initialization error message added recently
    needs to be reduced, because the particular BIOS issue indicated by
    it turns out to be widespread and doesn't really matter for the
    majority of systems having it.  From Jiang Liu.
 
  - The regulator API needs to be told to stay away from things on systems
    with ACPI BIOSes or it may conflict with the BIOS' own handling of
    voltage regulators.  Fix from Mark Brown that works around a 3.13
    regression in lm90 on PCs occuring if the regulator API is enabled.
 
  - Prevent the Exynos4 devfreq driver from being built on multiplatform,
    because it depends on things that aren't available during such builds.
    From Sachin Kamat.
 
  - Upstream ACPICA doesn't use the bool type as defined in the kernel,
    so modify the kernel's ACPICA code to follow the upstream in that
    respect (only one variable definition is affected) to reduce
    divergences between the two.  From Lv Zheng.
 
  - Make the ACPI device PM code use ACPI_COMPANION() instead of its own
    routine doing the same thing (and invokng ACPI_COMPANION() in the
    process).
 
  - Modify some routines in the ACPI processor driver to follow the
    common convention and return negative integers on errors.  From
    Hanjun Guo.
