Bob Moore b268cee867 ACPICA: Emit all unresolved method externals in a text block
Put all of the unresolved external method declarations in a single block,
since they are important and may cause the resulting disassembled ASL file
to not compile.
This patch only affects ACPICA utilities and is necessary to avoid adding
source code divergences between Linux and ACPICA upstream.

Ben Guthro d6b47b1224 ACPI / sleep: Introduce acpi_os_prepare_extended_sleep() for extended sleep path
Like acpi_os_prepare_sleep(), register a callback for use in systems
like tboot, and xen, which have system specific requirements outside
of ACPICA.  This mirrors the functionality in acpi_os_prepare_sleep(),
called from acpi_hw_sleep()

Lv Zheng 2cf9f5bcc8 ACPICA: Add acpi_update_interfaces() public interface
Add new API to allow OSPM to disable/enable specific types of _OSI
interface strings.

ACPICA does not have the knowledge about whether an _OSI interface
string is an OS vendor string or a feature group string and there
isn't any API interface to allow OSPM to install a new interface
string as a feature group string.
This patch simply adds all feature group strings defined by ACPI
specification into the acpi_default_supported_interfaces with
ACPI_OSI_FEATURE flag set to fix this gap.  This patch also adds
codes to keep their default states as ACPI_OSI_INVALID before the
initialization and after the termination.

 1. Sort the list ascending by C state type.
 2. Ensure type cannot be zero.
 3. A sub-package count of zero means _CST is meaningless.
 4. Count must match the number of C state sub-packages.

Lv Zheng 75e444606d ACPICA: Update initialization codes.
This patch decreases 18 lines of 20121018 divergence.diff.

This patch updates initialization codes as they are already been updated in
ACPICA. This can also help to reduce source code differences between Linux
and ACPICA.

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 9c0d793945 ACPICA: Cleanup coding style 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 314 lines of 20121018 divergence.diff.

ACPICA core uses ()'s on return statements. This is a known and committed
differences from Linux standard coding style.

This patch cleans up the Linux side ACPICA code to use this codying style
in order to reduce the source code differences between Linux and ACPICA.

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.
