stopped returning events. Don't disable the event when removing
the handler because it still needs to be enabled for the other
handler. Also, remove duplicate AcpiEnableEvent calls since the
install function now does this for us.
systems define power/sleep buttons in both places but only deliver
notifies to the ones defined in the AML.
Also, reduce length of various function handler names.

Implement this in acpi_MatchHid() and acpi_isa_get_compatid(). This
should fix mouse support for some users.
Move all users of AcpiGetObjectInfo() to use dynamic storage instead of
a devinfo on the stack. This is necessary since ACPI-CA needs to
allocate different sized arrays for the CompatList.
an acpi_cpu method for shutdown that disables entry to acpi_cpu_idle
and then IPIs/waits for threads to exit. This fixes a panic late in
reboot in the SMP case.
* In the !SMP case, don't use the processor id filled out by the MADT
since there can only be one processor. This was causing a panic in
acpi_cpu_idle if the id was 1 since the data was being dereferenced from
cpu_softc[1] even though the actual data was in cpu_softc[0] (which is
correct).
* Rework the initialization functions so that cpu_idle_hook is written
late in the boot process.
* Make the P_BLK, P_BLK_LEN, and cpu_cx_count all softc-local variables.
This will help SMP boxes that have _CST or multiple P_BLKs. No such
boxes are known at this time.
* Always allocate the C1 state, even if the P_BLK is invalid. This means
we will always take over idling if enabled. Remove the value -1 as
valid for cx_lowest since this is redundant with machdep.cpu_idle_hlt.
* Reduce locking for the throttle initialization case to around the write
to the smi_cmd port. Add disabled code to write the CST_CNT. It will
be enabled once _CST re-evaluation is tested (post 5.2R).

identical to the ACPICA version.

This is not known to have caused problems. Bug symptoms might have included
instability after an aborted suspend attempt or power/sleep buttons not
being enabled.
namespace has been evaluated. Machines with ACPI 2.0 expect this behavior
and have AML which calls EC functions early in the boot process. If the
ECDT is not available, fall back to original probe behavior.
Other minor changes:
* Add GPE bit and GLK usage to the device announcement
* Always use the global lock in the ECDT case, but potentially downgrade to
not using it if _GLK is 0 once the namespace is available. This is
announced with "Changing GLK from 1 to 0"
* Remove the acpi_object_list definitions which were earlier deprecated
Ideas from: takawata
* Use ACPI_BUFFER as the type for AcpiGetObjectInfo
* Remove AcpiEnableEvent/AcpiClearEvent for ACPI_EVENT_FIXED (power/sleep
buttons) as they are no longer needed
* Change calls to use the new GPE functions
* Add AcpiOs*Lock functions

- Change the apm driver to match the acpi driver's behavior by checking to
see if the device is disabled in the identify routine instead of in the
probe routine. This way if the device is disabled it is never created.
Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled". If this is a big problem, resource_disabled() can always be
changed to honor both names.

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

Switch the device to a group of wheel instead of operator.
Narrow down the permissions on the device to require root privilege
to manipulate the system power state. It may be that we can broaden
access to the device after review of the access control in ACPI.

any machine dependent initialization. This allows the MD code to set the
interrupt routing model so that PCI interrupts are routed correctly when
using an APIC or SAPIC for example.
Fix device hints entry for disabling acpi(4).
This also should fix the arbitration with apm(4) when both drivers
are enabled.
Note that your /boot/device.hints needs to be updated if you want to
stop auto-loading acpi.ko or disable acpi(4).
