      ACPICA: Cleanup coding style to reduce differences between Linux and ACPICA. · 9c0d7939
      由 Lv Zheng 提交于 
      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.

      ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA. · 3e8214e5
      由 Lv Zheng 提交于 
      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.

      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.

      ACPICA: Update codes under disabled build options. · 56324c10
      由 Lv Zheng 提交于 
      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 170 lines of 20121018 divergence.diff.

This patch updates ACPICA codes surrounded by some disabled build options
so that the source code diff between Linux and ACPICA can be reduced.

Some of these build options may never be used in the kernel, so they may
be deleted entirely in future patches.

      ACPICA: Cleanup updated comments. · 75c8044f
      由 Lv Zheng 提交于 
      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.

      ACPI: delete _GTS/_BFS support · 3f6f49c7
      由 Len Brown 提交于 
      _GTS and _BFS were added to the suspend/resume flow
in the ACPI 2.0 specification.

Linux dutifully implemented _GTS and _BFS.
We discovered that it was rarely seen in systems
in the field.  Further, some of those systems had
AML so bogus that it could never work -- proof that
no other operating system supports _GTS and _BFS.
So we made _GTS and _BFS optional via modparam,
and disabled them by default.

But we've had to complicate some code to keep
this support in the kernel, as these methods are defined
to be evaluated very close to sleep entry and exit.
Indeed, no other AML is ever evaluated with interrupts off.

We have submitted a proposal for _GTS and _BFS
to be officially removed from the ACPI specification
on the next revision.  Here we remove it from Linux.
