a67e6f3ab1 Instead of trusting _STA from power resources, cache the first value
returned and then infer the state from calls to _ON/_OFF.  This works
around a problem in systems that don't correctly report the state (i.e.
the HP Omnibook 500 reports "on" for its fan always after it has been
turned on once).

d317428f44 MPSAFE locking
* Serialize acpi_pwr_switch_consumer() and acpi_pwr_wake_enable().
* Make acpi_pwr_switch_consumer() have a single exit point.
* Add assertions to the leaf functions they call.
* Fix a memory leak in acpi_pwr_deregister_consumer().  However, it is
  currently ifdefed out so this code was unused.

d3b9d3d1d7 Add a method for referencing/switching power resources based on _PRW.
This brings us into line with the standard, which requires power resources
be enabled when wake is enabled for a given device.  Move the dereferencing
code into its own function, +acpi_pwr_dereference_resource().

45e556cc69 Avoid printing extraneous warning messages when trying to switch a device
which doesn't support ACPI power states.  Return AE_NOT_FOUND for these
cases and don't print the warning message.  Also, print the name of the
handle instead of device when unable to switch states.  The device is often
not attached at this point and so its name is NULL, which doesn't help
debugging.

aa95c5b148 Replace more ad-hoc versions of acpi_GetReference(). Since the type of
Reference objects changed from ACPI_TYPE_ANY to ACPI_TYPE_LOCAL_REFERENCE
in Oct. 2002, this may help systems where switching the cooler on failed.
We support both types for now until this sorts out.

c310653ea1 Change to acpi_{Get,Set}Integer to provide both methods. Convert all
callers to the new API.

3184cf5a6b Add support for quirks for acpi tables. Key off OEM vendor and revision.
Sort acpi debug values.  Change "disable" to "disabled" to match rest of
the kernel.  Remove debugging from acpi_toshiba since it was only used for
probe/attach.

cfd820d382 Fix a bug about the cooling system controlling in acpi_thermal driver.
Recent version of ACPI CA returns the package object which contains
object reference elements if the elements are named objects.
We need to be careful when you use acpi_ForeachPackageObject() in new
code...

c573e654b7 Add OS layer ACPI mutex and threading support.
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

dfcd35dd08 Whoops; we get an ACPI_OBJECT back from evaluating a method, not
an ACPI_OPERAND_OBJECT.  Fix this so that the power resource type
can be properly checked, and we can get the system level and
resource order.

c5ba0be495 Sync to my work in progress:
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.
