9becf5b91e ACPI: asus_acpi: correct M6N/M6R display nodes
This patch switches back the display nodes for M6R and M6N -- this happened
a while ago when a patch was misapplied (only the in-tree version was
affected).

ffab0d9507 ACPI: asus_acpi: rework model detection
This patch reworks laptop model detection.

This addresses the Samsung P30 issue, where the INIT method would return no
object, but the implicit return in the AML interpreter would confuse the
driver. It also accounts for a newer batch of Asus models whose INIT
returns ACPI_TYPE_BUFFER instead of STRING.

The handling is now much leaner, if we get a buffer or a string, we check
against known values, in every other case we use a different path
(currently DSDT signatures). The bulk of this patch is separating the
string matching from asus_hotk_get_info() into a separate function.

This patch properly fixes http://bugme.osdl.org/show_bug.cgi?id=5067 and
http://bugme.osdl.org/show_bug.cgi?id=5092 and makes the driver fully
functional again with acpi=strict on all machines.

e067aaa761 ACPI: asus_acpi: handle internal Bluetooth / support W5A
This patch creates a new file named "bluetooth" under /proc/acpi/asus/.
This file controls both the internal Bluetooth adapter's presence on the
USB bus and the associated LED.

echo 1 > /proc/acpi/asus/bluetooth to enable, 0 to disable.

Additionally, the patch add support for Asus W5A, the first model that uses
this feature.

b229cf92ee ACPI: ACPICA 20060421
Removed a device initialization optimization introduced in
20051216 where the _STA method was not run unless an _INI
was also present for the same device. This optimization
could cause problems because it could allow _INI methods
to be run within a not-present device subtree (If a
not-present device had no _INI, _STA would not be run,
the not-present status would not be discovered, and the
children of the device would be incorrectly traversed.)

Implemented a new _STA optimization where namespace
subtrees that do not contain _INI are identified and
ignored during device initialization. Selectively running
_STA can significantly improve boot time on large machines
(with assistance from Len Brown.)

Implemented support for the device initialization case
where the returned _STA flags indicate a device not-present
but functioning. In this case, _INI is not run, but the
device children are examined for presence, as per the
ACPI specification.

Implemented an additional change to the IndexField support
in order to conform to MS behavior. The value written to
the Index Register is not simply a byte offset, it is a
byte offset in units of the access width of the parent
Index Field. (Fiodor Suietov)

Defined and deployed a new OSL interface,
acpi_os_validate_address().  This interface is called during
the creation of all AML operation regions, and allows
the host OS to exert control over what addresses it will
allow the AML code to access. Operation Regions whose
addresses are disallowed will cause a runtime exception
when they are actually accessed (will not affect or abort
table loading.)

Defined and deployed a new OSL interface,
acpi_os_validate_interface().  This interface allows the host OS
to match the various "optional" interface/behavior strings
for the _OSI predefined control method as appropriate
(with assistance from Bjorn Helgaas.)

Restructured and corrected various problems in the
exception handling code paths within DsCallControlMethod
and DsTerminateControlMethod in dsmethod (with assistance
from Takayoshi Kochi.)

Modified the Linux source converter to ignore quoted string
literals while converting identifiers from mixed to lower
case. This will correct problems with the disassembler
and other areas where such strings must not be modified.

The ACPI_FUNCTION_* macros no longer require quotes around
the function name. This allows the Linux source converter
to convert the names, now that the converter ignores
quoted strings.

200739c179 ACPI: remove __init/__exit from Asus .add()/.remove() methods
Even though the devices claimed by asus_acpi.c can not be hot-plugged, the
driver registration infrastructure allows the .add() and .remove() methods to
be called at any time while the driver is registered.  So remove __init and
__exit from them.

578b333bfe ACPI: update asus_acpi driver registration to unload on failure
Remove the assumption that acpi_bus_register_driver() returns the number of
devices claimed.  Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).

Since the hardware for this driver is not hot-pluggable, determine whether the
hardware is present by noticing calls to the .add() method.  It would be
better to probe the ACPI namespace for the ASUS HIDs, and load the driver only
when we find one, but ACPI doesn't support that yet.

I don't have an ASUS laptop to test on, but on my HP dl360, it does report the
appropriate error when attempting to load the module:

    $ sudo insmod drivers/acpi/asus_acpi.ko
    insmod: error inserting 'drivers/acpi/asus_acpi.ko': -1 No such device

b697b5372e [ASUS_ACPI] work around Samsung P30s oops
The code used to rely on a certain method to return a NULL buffer, which
is now hardly possible with the implicit return code on by default. This
sort of fixes bugs #5067 and #5092 for now.

Note: this patch makes the driver unusable on said machines (and on said
machines only) iff acpi=strict is specified, but it seems noone really uses
that.

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!
