Adrian Bunk points out that it has build errors, and apparently no
maintenance. Throw it out.

Create a driver which lives in the acpi subsystem to handle dock events.
This driver is not an "ACPI" driver, because acpi drivers require that the
object be present when the driver is loaded.

Nobody looks at the return value, and this brings it into line with
pci_unregister_driver(), etc.  Also removed validation of the driver
pointer passed in to register and unregister.  More consistent, and we'll
find bugs faster if we fault rather than returning an error that's ignored.

Also makes internal functions acpi_device_unregister() and
acpi_driver_detach() void, since nobody uses their returns either.

acpi_bus_register_driver() should not return the number of devices claimed.
We're not asking to find devices, we're making a driver available to devices,
including hot-pluggable devices that may appear in the future.

I audited all callers of acpi_bus_register_driver(), and except asus_acpi.c
and sonypi.c (fixed in previous patches), all either ignore the return value
or test only for failure (<0).

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

Fixed a problem in the AML parser where the method thread
count could be decremented below zero if any errors
occurred during the method parse phase. This should
eliminate AE_AML_METHOD_LIMIT exceptions seen on some
machines. This also fixed a related regression with the
mechanism that detects and corrects methods that cannot
properly handle reentrancy (related to the deployment of
the new OwnerId mechanism.)

Eliminated the pre-parsing of control methods (to detect
errors) during table load. Related to the problem above,
this was causing unwind issues if any errors occurred
during the parse, and it seemed to be overkill. A table
load should not be aborted if there are problems with
any single control method, thus rendering this feature
rather pointless.

Fixed a problem with the new table-driven resource manager
where an internal buffer overflow could occur for small
resource templates.

Implemented a new external interface, acpi_get_vendor_resource()
This interface will find and return a vendor-defined
resource descriptor within a _CRS or _PRS
method via an ACPI 3.0 UUID match. (from Bjorn Helgaas)

Removed the length limit (200) on string objects as
per the upcoming ACPI 3.0A specification. This affects
the following areas of the interpreter: 1) any implicit
conversion of a Buffer to a String, 2) a String object
result of the ASL Concatentate operator, 3) the String
object result of the ASL ToString operator.

Create new interfaces to recursively add an acpi namespace object to the acpi
device list, and recursively start the namespace object.  This is needed for
ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
