[PATCH 00/18] ACPICA: 20140214 Release

[PATCH 00/18] ACPICA: 20140214 Release

[Lv Zheng]

The 20140214 ACPICA kernel resident system updates are linuxized based on
the pm/linux-next branch.

The patch set has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. i386 + allyes + CONFIG_ACPI=y
3. i386 + default + COFNIG_ACPI=n
4. i386 + allyes + CONFIG_ACPI=n
5. x86_64 + default + COFNIG_ACPI=y
6. x86_64 + allyes + CONFIG_ACPI=y
7. x86_64 + default + COFNIG_ACPI=n
8. x86_64 + allyes + CONFIG_ACPI=n
Boot tests are performed as follows:
1. i386 + default + COFNIG_ACPI=y
2. x86_64 + default + COFNIG_ACPI=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "HP Compaq 8200 Elite SFF PC"
3. default: kernel configuration with following items enabled:
   All hardware drivers related to the machines of i386/x86_64
   All drivers/acpi configurations
   All platform drivers
   All ACPI drivers
   4 DRM drivers that implement ACPI opregion
   All buses with ACPI bindings
   All cpufreq configurations
   All xen configurations
   All ACPI tabln drivers
4. allyes: kernel configuration generated by allyesconfig.

Excluded the divergence reductions that are managed, after applying this
series, the divergence result is 889 Lines, 31.3 Kbytes.

[PATCH 01/18] ACPICA: Headers: Deploy #pragma pack (push) and (pop).

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

Use push and pop to both guarantee that the correct alignment is used,
and to restore the alignment to whatever it was before the header
was included.

It is reported that the #pragma pack(push/pop) directives are not supported
by the specific GCCs.  While this patch still doesn't affect kernel build
as there are already #pragma pack([1]) directives used in the old ACPICA
headers, which means there shouldn't be GCCs that are currently used to
compile the ACPI kernels do not support #pragma pack() directives.

[PATCH 03/18] ACPICA: Update conditional compilation flags for resource dump functions.

[Lv Zheng]

Corrects ACPI_DISASSEMBLER to the compile conditions.  The wrong
condition was introduced by this commit:
  Commit: 3334861b1e9947631230b573eba27bcd778b93c8
  Subject: ACPICA: Update the conditions to enable the utility resource dump strings.

This was detected in the ACPICA upstream.  Linux is not affected by the
wrong commit as the disassembler is not shipped in the Linux.

[PATCH 05/18] ACPICA: Restore code that repairs NULL package elements in return values.

[Lv Zheng]

The original code was lost accidently, it was not generated along with the
following commit of mechanism improvements and thus not get merged:

  Commit: d5a36100f62fa6db5541344e08b361b34e9114c5
  Subject: ACPICA: Add mechanism for early object repairs on a per-name basis

  Adds the framework to allow object repairs very early in the
  return object analysis. Enables repairs like string->unicode,
  etc.

This patch restores the implementation of the NULL element repair code for
ACPI_RTYPE_NONE.  In the original design, ACPI_RTYPE_NONE is defined to
collect simple NULL object repairs.

[PATCH 08/18] ACPICA: Add auto-serialization support for ill-behaved control methods.

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

This change adds support to automatically mark a control method as
"serialized" if the method creates any named objects. This will
positively prevent the method from being entered by more than one
thread and thus preventing a possible abort when an attempt is
made to create an object twice.

Implemented by parsing all non-serialize control methods at table
load time.

[PATCH 10/18] ACPICA: Add additional named objects for the auto-serialize method scan.

[Lv Zheng]

This change adds some additional opcodes that are detected and will
cause a method to be auto-serialized. These opcodes are the various
CreateXField and the FieldUnit opcodes. Lv Zheng.

[PATCH 12/18] ACPICA: Remove global option to serialize all control methods.

[Lv Zheng]

With the addition of the auto-serialization feature, this option
is obsolete and is completely removed. Lv Zheng.

This patch also updates acpi_serialize kernel parameter using the
new auto-serialization feature - acpi_gbl_auto_serialize_methods.

[PATCH 13/18] ACPICA: Cleanup/improve global variable declarations.

[Lv Zheng]

This change cleans up the entire global variable mechaninism including
the related macros. Also reduces warnings from the "sparse" utility
in the Linux environment. Lv Zheng.

+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ *    the latest version of Windows, which would respond to the latest/newest
+ *    _OSI string. Not responding TRUE to the latest version of Windows will
+ *    risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ *    has the potential to cause problems on existing working machines because
+ *    of the possibility that a new and different path through the ASL code
+ *    will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ *    in recognizing a new string for a significant amount of time risks the
+ *    release of another string which only compounds the initial problem.

[PATCH 16/18] ACPICA: Debugger: Add missing objects; Traverse linked lists

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

This change adds support for two missing objects, the "extra" and
"data" secondary objects, as well as adding support to traverse and
display linked lists related to ACPICA objects.

[PATCH 17/18] ACPICA: Prevent infinite loops when traversing corrupted lists.

[Lv Zheng]

From: Bob Moore <robert.moore@intel.com>

This change hardens the ACPICA code to detect circular linked object
lists and prevent an infinite loop if such corruption exists.

[PATCH] ACPICA: Revert "Headers: Deploy #pragma pack (push) and (pop)."

[Lv Zheng]

From: Robert Moore <Robert.Moore@intel.com>

This reverts commit aae576e5faefa8ba70647efa320d4747b6375f1e.
Push and Pop are not portable "enough", and caused problems for
some ACPICA customers.
