9bb04eb483 Add status initialization code for acpi_cmbat and acpi_acad,
acpi_cmbat_init_battery() and acpi_cmbat_init_acline() respectively.
Call acpi_cmbat_init_battery() from acpi_cmbat_resume() too just in
case.
This is a workaround for embedded controller operations which is
unstable for about a minute (typically 30 or 40 sec.) at boot time.

899ccf541a Add generalized power profile code.
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified
the events.

 - move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
 - call power_profile_set_state() also from APM driver when AC-line
   status changes
 - add call-back function for Crusoe LongRun controlling on power
   profile changes for a example

6971b3c7d1 Cleanups of verbose printing. All the messages for the debugging is
disabled unless verbose flag is set.  Also fix some messages in terms
of English.
The critical messages and error messages in probe/attach routine are
unchanged by this commit.

f86214b6b8 Add APM compatibility feature to ACPI.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications.  The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
 - APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
 - APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
 - APMIO_GETINFO and APMIO_GETINFO_OLD
 - APMIO_GETPWSTATUS

With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

1dffb34a9a 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.

- Set system power profile only when AC-line status has canged.
 - Get initial AC-line status after whole system is up.

91467fc61d ACPI_NUMBER becomes ACPI_INTEGER. acpi_EvaluateNumber becomes
acpi_EvaluateInteger.

Use acpi_EvaluateInteger instead of doing things the hard way where
possible.

AcpiSetSystemSleepState (unofficial) becomes AcpiEnterSleepState.

Use the AcpiGbl_FADT pointer rather than searching for the FADT.
