Whitespace cleanups (verified with MD5 1832ce5ede6c58c844dfb53fd48f0eea).
Also clarify a macro expansion with an XXX. I will be fixing access to
Acpi Global Lock in a subsequent commit.

Resolve conflicts arising from the ACPI CA 20021118 import.

Add new loader tunable hw.acpi.ec.event_driven so that we control
EcWaitEventIntr()'s behavior.
Some EC controllers require this for working properly (including
sleep/wakeup).

Catch up to changes in acpivar.h to add support for using ACPI on
4-stable systems.

Make interrupt driven EC transaction optional.

Brutally deal with __func__ being 'const char *' on gcc-3.1.

Match namespace cleanup changes in ACPI CA 20020217 update.
Use ACPI_SUCCESS/ACPI_FAILURE consistently.

The ACPI global lock acquire takes a timeout value. I'm not sure what
we should do about timeouts on it; a deadlock against this lock is
catastrophic.

Staticise devclasses and some unnecessarily global variables.

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 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.

Don't parse our resources ourself, the ACPI core code must do it.

Updates to match the ACPI CA 20010816 import:

- New debug macro (ACPI_DEBUG_PRINT), reducing debug-case code size.
- New debug level/subsystem codes.

Convert from acpi_strerror() to AcpiFormatException()

Fix dangling include of the dear departed acpi_ecreg.h

Merge the EC register definitions into the EC module proper, they're not
used anywhere else.

AcpiOsSleepUsec() -> AcpiOsStall()

Improve some error messages slightly.

Use msleep() when we sleep waiting for a GPE, since we are holding the
ACPI mutex.

Add some comments to EcWaitEventIntr.

Clean up deviant style, add debugging to be consistent.

- Use __func__ instead of __FUNCTION.
- Support power-off to S3 or S5 (takawata)
- Enable ACPI debugging earlier (with a sysinit)
