67ce16735b Don't call ourselves a "control method" anything, that's not useful.
Move the "button pressed" diagnostics to the point where we can print
out which button was actually pressed.

2a4ac806d7 - Updates for new constant naming in the ACPI CA 20010518 update.
- Use __func__ instead of __FUNCTION.
 - Support power-off to S3 or S5 (takawata)
 - Enable ACPI debugging earlier (with a sysinit)
 - Fix a deadlock in the EC code (takawata)
 - Improve arithmetic and reduce the risk of spurious wakeup in
   AcpiOsSleep.
 - Add AcpiOsGetThreadId.
 - Simplify mutex code (still disabled).

0ae554237c - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.

15e32d5d03 Initial FreeBSD OSPM (operating system power management) modules for
ACPICA.  Most of these are still works in progress.  Support exists for:

 - Fixed feature and control method power, lid and sleep buttons.
 - Detection of ISA PnP devices using ACPI namespace.
 - Detection of PCI root busses using ACPI namespace.
 - CPU throttling and sleep states (incomplete)
 - Thermal monitoring and cooling control (incomplete)
 - Interface to platform embedded controllers (mostly complete)
 - ACPI timer (incomplete)
 - Simple userland control of sleep states.
 - Shutdown and poweroff.
