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.

11dfccde73 Use the _STA method of a battery control method to see if a battery is
present or not.  My laptop now properly notices when a battery is removed.

8b79649b5b Do not concatenate __func__ with strings, because it is not a string.
Later gcc's blow up on this.

595a08978c Match namespace cleanup changes in ACPI CA 20020217 update.
Use ACPI_SUCCESS/ACPI_FAILURE consistently.
The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER.

Kill off the timeouts that used to read _BIF and _BST.  These are
invoked when the battery is actually read.  timeout() is dangerous
in combination with ACPI, as the interpreter can block.

This driver still needs more work.

c573e654b7 Add OS layer ACPI mutex and threading support.
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

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.

3fa010222f Oops, deleted wrong BIF acquisition timeout invocation by mistake
in my previous commit.
acpi_cmbat_get_bif() from taskqueue calls acpi_cmbat_timeout() so it's
better for startup.

9febbb4078 Some improvements of control method battery driver.
- Add a new MIB for battery info expire time in order to make it changeable.
   Battery info expire time can be specified by
   hw.acpi.battery.info_expire in sec.
 - Add own MALLOC type and fix some potential memory leakages.
 - Change some frequent printings to verbose printing.
 - Stop timeout during acpi_cmbat_get_bst() too.  This should reduce
   the races with BIF evaluation.
 - Remove acpi_cmbat_get_bif() invocation from acpi_cmbat_attach().
   This was redundant because this should be called from
   acpi_cmbat_timeout() now.

 - 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).

e3225e78f7 When ensuring the destination buffer is truncated for a string obtained
from a BIF, use the size of the destinatino buffer, not the length of the
string to determine where to put the nul char.  As a side effect, the
old code would truncate the string by one character while it was possibly
overflowing the buffer.

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.
