6c165fc101 Move the timer difference convenience function from acpi_cpu.c to make it 
globally available.  acpi_TimerDelta() subtracts two readings from the
ACPI PM timer and returns the difference.  It properly distinguishes between
24-bit and 32-bit timers and handles wraparound.

8059c69810 Allow the AC adapter device to be disabled with debug.acpi.disable="acad". 
Even though documented, this option was never enabled even in rev 1.1.

fce4fe318a Add a temporary workaround for acpi_AppendBufferResource() returning with 
a NULL crsbuf pointer.  This shouldn't happen if it returns AE_OK.  We'll
figure out why this is happening later.

8d672f8640 Disable the new wake GPE behavior. With it enabled, my laptop won't stay 
suspended after the second try.  Intel is working on a fix to properly
differentiate the non-standard wake/runtime GPEs from wake-only GPEs.

ca56ea20fc Omnibus PCI commit: 
o Save and restore bars for suspend/resume as well as for D3->D0
	  transitions.
	o preallocate resources that the PCI devices use to avoid resource
	  conflicts
	o lazy allocation of resources not allocated by the BIOS.
	o set unattached drivers to state D3.  Set power state to D0
	  before probe/attach.  Right now there's two special cases
	  for this (display and memory devices) that need work in other
	  areas of the tree.

Please report any bugs to me.

6c09d371b9 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.

baec2dbefc Implement an ACPI-aware pci_set_powerstate() method for PCI busses that 
are enumerated in the ACPI device tree.  In addition to the normal PCI
powerstate functionality, the ACPI _PSx methods are executed and ACPI
PowerResources are switched on and off via the acpi_pwr_switch_consumer()
function.

d976b2d5bf Move the ivar accessing routines back to inlines (reverting acpivar.h 
rev 1.44 and acpi.c rev 1.96).  Now gcc can handle larger inlines and we
really need external drivers to be able to read their acpi ivars.

b33d64d240 Disable serialize_methods and enable _OSI support by default. The former 
is necessary because some IBMs use recursive methods (pointed out by
Robert Moore from Intel).  The latter was a typo on my part.  It was disabled
by default when it should have been enabled.

27ea45097f A user can set tz_requested via the hw.acpi.thermal.tzX.active sysctl. 
The previous logic meant that if a user sets it to a minimal cooling value
acpi_thermal will not use higher cooling levels.  Reverse the logic so that
the user requesting a level (say, 2) also gets 0 - 1 also.
