4e376d58dc Add a "quirks" value to disable quirks handling for a given boot.
Also, disable quirks if booting with a custom DSDT.  Add a quirk
to disable loading ACPI so known bad systems can be completely
blacklisted.

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.

dc08ffec87 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

c9c7976f7f Device megapatch 1/6:
Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

968c0e1bf4 Fix problem caused by previous commit where some users' buttons
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.

33febf93d6 Prefer buttons defined in the AML over the ones in the FADT. Some
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.

1e4925e8d3 Add support for multiple CIDs since _CID can contain a package of values.
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.

56a70eadf5 * Add a DEVMETHOD for acpi so that child detach methods get called. Add
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).

f8335e3a97 Add ECDT (ACPI 2.0) support. This allows the EC to be enabled before the
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

8a9bc9c03b - Use the new resource_disabled() helper function to see if devices are
disabled.
- 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.

branches:

Initialize struct cdevsw using C99 sparse initializtion and remove

2a4689e84a Change ACPI make_dev() calls to use UID_ and GID_ constants rather

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.
