Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

Fix a witness(4) warning introduced in r217238.

Remove impossible error conditions.

Add forgotten free(9) in the previous commit for an error case.

Allow AcpiOsInstallInterruptHandler() and AcpiOsRemoveInterruptHandler() to
install or remove non-SCI interrupt handlers per ACPI Component Architecture
User Guide and Programmer Reference. ACPICA may install such interrupt
handler when a GPE block device is found, for example. Add a wrapper for
ACPI_OSD_HANDLER, convert its return values to ours, and make it a filter.
Prefer KASSERT(9) over panic(9) as we have never seen those in reality.
Clean up some style(9) nits and add my copyright.

Import ACPICA 20090521.

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

MPSAFE locking

* Remove the interrupt wrapper that locked Giant and call the handler
directly. Mark the handler as MPSAFE.
* Don't attempt to detect if a handler is installed. Leave that to the
bus_alloc_resource() function.

Style cleanup, plus properly backup partial resource allocation in
AcpiOsInstallInterruptHandler() in the case of failure to initialize.

Convert callers to the new bus_alloc_resource_any(9) API.

Reindent to non-style(9) compliant 4 space indent to match rest of file.

Add an ACPI_FUNCTION_TRACE() invocation to acpi_OverrideInterruptLevel()
to fix compile with ACPI_DEBUG.

Add an acpi_OverrideInterruptLevel() method that OSPM can use to override
the InterruptLevel used for the SCI.

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

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

Match namespace cleanup changes in ACPI CA 20020217 update.

find_devclass -> devclass_find.

Staticise devclasses and some unnecessarily global variables.

Synch with minor changes in the ACPI CA 20011120 snapshot.

Better checking of duplicated interrupt handler installation.

Get the ACPI softc before we potentially dereference it.

Wrap the interrupt handler so that we can get the ACPI lock.

- 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).

Add some debugging statements.
