Bob Moore 04a81dce13 ACPICA: Eliminate some small unnecessary pathname functions.
Removed several small pathname functions to increase efficiency.
Essentially, they replace a function call with a single compare.

Lv Zheng 7b6afb6782 ACPICA: Fix broken call depth tracing logic.
This patch does not affect the generation of the Linux binary.
This patch decreases 26 lines of 20121018 divergence.diff.

The ACPICA uses a call depth tracing mechanism by wrapping the return
statements with return macros and marking the entrance with
ACPI_FUNCTION_TRACE_ macros. There are other ACPI_FUNCTION_ macros used
to mark the functions not using this tracing mechanism.

This patch fixes broken call depth tracing logic.

Lv Zheng 3e8214e5c2 ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 210 lines of 20121018 divergence.diff.

The ACPICA source codes uses a totally different indentation style from the
Linux to be compatible with other users (operating systems or BIOS).

Indentation differences are critical to the release automation. There are
two causes related to the "indentation" that are affecting the release
automation:
1. The ACPICA -> Linux release process is:
     ACPICA source -- acpisrc - hierarchy - indent ->
     linuxized ACPICA source -- diff ->
     linuxized ACPICA patch (x) -- human intervention ->
     linuxized ACPICA patch (o)
     Where
       'x' means "cannot be directly applied to the Linux"
       'o' means "can be directly applied to the Linux"
   Different "indent" version or "indent" options used in the "indent"
   step will lead to different divergences.
   The version of "indent" used for the current release process is:
     GNU indent 2.2.11
   The options of "indent" used for the current release process is:
     -npro -kr -i8 -ts8 -sob -l80 -ss -ncs
2. Manual indentation prettifying work in the Linux side will also harm the
   automatically generated linuxized ACPICA patches, making them impossible
   to apply directly.

This patch fixes source code differences caused by the two causes so that
the "human intervention" can be reduced in the future.

Lv Zheng 739dcbb90a ACPICA: Cleanup source to reduce differences between Linux and ACPICA.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 389 lines of 20121018 divergence.diff.

This patch reduces source code diff caused by the simple code maintenance
work:
1. Deletion of the unused include files.
2. Deletion of the deprecated codes blocks.
3. Repositioning of the code blocks.
4. Replacing the values with the well defined macros.
5. Replacing the types with the equivalent types.

Lv Zheng 75c8044fb3 ACPICA: Cleanup updated comments.
This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.

This patch does not affect the generation of the Linux binary.
This patch decreases 558 lines of 20121018 divergence.diff.

This patch reduces the source code diff between Linux and ACPICA by
cleaning the comments that already have been updated in ACPICA.

There is no extra indentation done in this patch. Even the empty line
deletions and insertions are also splitted into another cleanup patch so
that this patch can be easily reviewed, and the binary differences can be
held to a lowest level.

Lv Zheng 78e25fef27 ACPICA: Fix divergences of definition conflicts.
There are conflicts in the "acpi_device_id*" definitions between the
Linux and the ACPICA.  The definitions of acpi_device_id* in ACPICA
have been changed to the "acpi_pnp_device_id*".  This patch changes
the corresponding "acpica_device_id*" definitiions in the Linux.

This patch will not affect the generated vmlinx binary.
This will decrease 298 lines of 20120913 divergence.diff.

Fixes issues like this:

i_aSL -> iASL
00-7_f -> 00-7F
local_fADT -> local_FADT
execute_oSI -> execute_OSI

Also, in function headers, the parameters are now translated to
lower case (with underscores if necessary.)

Paul Gortmaker 214f2c90b9 acpi: add export.h to files using THIS_MODULE/EXPORT_SYMBOL
These files were relying on module.h to come in via the path
in an include/acpi header file, but we don't want to have
instances of module.h being included from include/* files
if it can be avoided.  Have the files include export.h instead.

Bob Moore 15b8dd53f5 ACPICA: Major update for acpi_get_object_info external interface
Completed a major update for the acpi_get_object_info external interface.
Changes include:
 - Support for variable, unlimited length HID, UID, and CID strings
 - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
 - Call the _SxW power methods on behalf of a device object
 - Determine if a device is a PCI root bridge
 - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.

Also, update all invocations of acpi_get_object_info interface

Luca Tettamanti 2c03d07ad5 hwmon: Add Asus ATK0110 support
Asus boards have an ACPI interface for interacting with the hwmon (fan,
temperatures, voltages) subsystem; this driver exposes the relevant
information via the standard sysfs interface.

There are two different ACPI interfaces:
- an old one (based on RVLT/RFAN/RTMP)
- a new one (GGRP/GITM)
Both may be present but there a few cases (my board, sigh) where the
new interface is just an empty stub; the driver defaults to the old one
when both are present.
The old interface has received a considerable testing, but I'm still
awaiting confirmation from my tester that the new one is working as
expected (hence the debug code is still enabled).

Currently all the attributes are read-only, though a (partial) control
should be possible with a bit more work.

Bob Moore 8a335a2331 ACPICA: Fix AcpiWalkNamespace race condition with table unload
Added a reader/writer locking mechanism to allow multiple
concurrent namespace walks (readers), but a dynamic table unload
will have exclusive access to the namespace. This fixes a problem
where a table unload could delete the portion of the namespace that
is currently being examined by a walk.  Adds a new file, utlock.c
that implements the reader/writer lock mechanism. ACPICA BZ 749.
