8ccf25b79d Initialise the adapter status to an invalid state, so that the initial check 
of the adapter object will always result in a change event.

This fixes the problem where a laptop booted without an AC adapter ran
at 100% CPU speed by default.

a19dd226fc Just print a message in acpi_tz_monitor() only when new active state 
is different from the previous active state.
This reduce tons of 'acpi_tz0: _AC0: temperature 64.0 >= setpoint 64.0'
messages.

2f50c10b5b Add a MODULE_VERSION declaration. This should prevent duplicate loading 
of the module, and allows other modules to depend on and link against
the ACPI module.

Add a sysctl that allows us to retrieve the ACPI CA version number as
well.

d83b514457 Add support for attaching PnP-aware ISA drivers to ACPI. 
Always parse ACPI device resource settings (current resources only)
and attach the resources to the device before probe/attaching.

48c2759e11 Retarget the resource parser slightly. We only fetch current resources 
for the device now (we should really just be parsing a passed-in resource
buffer).

Wrap long lines so this is (more) readable.

Support Address16 and Address32 resources, in the CONSUMER case.

Support DRQs so that we can handle ISA devices.

Support ExtendedIrqs (we ignore most of their attributes)

Add a placeholder device for system memory and system resources.  This
takes the place of the nexus placeholder, which only attaches to ISA.

8f6b46742a Note that now that some ISA devices will attach to ACPI, we need to 
keep the ivar indexes that ISA uses free.

9b55e30943 The current resource buffer returned from an interrupt link device 
in the case where there are no interrupts routed for it does not
contain enough space to use it to route an interrupt.  In the case
where we need to route an interrupt, throw away the returned buffer

f3637b944d - Prevent the ACPI code from being loaded as a module other than at 
boot time.  Loading as a module once the system is up and running
   doesn't make any sense.

 - Fix acpi_FindIndexedResource (it would only check the first resource),
   changes the calling interface.

 - Add a new helper function (acpi_AppendBufferResource) to help building
   buffers containing resources.

- Remove the beer-ware license (reqested by phk)
 - Reorganise so that the PIIX4 workaround code is kept together, and
   switch the workaround function via the timecounter struct, saving
   a compare in the read-timecounter codepath.  Also indicate that
   the workaround is active by changing the timecounter hardware string.

b364b2c885 Implement a "proper" timecounter hung off the ACPI timer device. 
This code is based on the mp_clock code by phk.  It attempts to
detect the PIIX4 (see comments for details) and use a workaround
for its problems.

This code is experimental, and could use some testing and review by a
timekeeping enthusiast.

fdc534151a The API for loading tables changed (we no longer explicitly search for the 
RSDP, it's now found via a callback).

AcpiOsSleepUsec() went away, use AcpiOsSleep() instead (we could use
AcpiOsStall() too)

AcpiFormatException() was changed to make more sense (it behaves like
our old acpi_strerror() did), so throw acpi_strerror() away (still
#defined in acpivar.h though, we need to sweep these seperately).
