ab6c573320 ACPICA: Executer: Add interpreter tracing mode for method tracing facility
ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

The acpi_debug_trace() is the mechanism known as ACPI method tracing that is
used by Linux as ACPICA debugging message reducer. This facility can be
controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
logs in the kernel dmesg output.

This patch enhances acpi_debug_trace() to make it not only a message reducer,
but a real tracer to trace AML interpreter execution. Note that in addition
to the AML tracer enabling, this patch also updates the facility with the
following enhancements:
1. Allow a full path to be specified by the acpi_debug_trace() API.
2. Allow any method rather than just the entrance of acpi_evaluate_object()
   to be traced.
3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
   ACPI_EXECUTER layer.

The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
and the duplicated stubs are removed after that.

Note that since this patch has enhanced the method tracing facility, Linux
need also be updated after applying this patch. Lv Zheng.

a616dc2fe5 ACPICA: Dispatcher: Add trace support for interpreter
ACPICA commit 71299ec8b49054daace0df50268e8e055654ca37

This patch adds trace point at the following point:
 1. Begin/end of a control method execution;
 2. Begin/end of an opcode execution.

The trace point feature can be enabled by defining ACPI_DEBUG_OUTPUT
and specifying a debug level that includes ACPI_LV_TRACDE_POINT and the
debug layers that include ACPI_PARSER and ACPI_DISPACTCHER.

In order to make aml_op_name of union acpi_parse_object usable for tracer, it is
enabled for ACPI_DEBUG_OUTPUT in this patch. Lv Zheng.

62eb935b77 ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address assignments
ACPICA commit afb52611dbe7403551f93504d3798534f5c343f4

This patch cleans up the code of assigning the AML address to the
union acpi_operand_object.

The idea behind this cleanup is:
The AML address of the union acpi_operand_object should always be determined at
the point where the object is encountered. It should be started from the
first byte of the object. For example, the opcode of the object, the name
string of the user_term object, or the first byte of the packaged object
(where a pkg_length is prefixed). So it's not cleaner to have it assigned
here and there in the entire ACPICA source tree.

There are some special cases for the internal opcodes, before cleaning up
the internal opcodes, we should also determine the rules for the AML
addresses of the internal opcodes:
1. INT_NAMEPATH_OP: the address of the first byte for the name_string.
2. INT_METHODCALL_OP: the address of the first byte for the name_string.
3. INT_BYTELIST_OP: the address of the first byte for the byte_data list.
4. INT_EVAL_SUBTREE_OP: the address of the first byte for the
                        Region/Package/Buffer/bank_field/Field arguments.
5. INT_NAMEDFIELD_OP: the address to the name_seg.
6. INT_RESERVEDFIELD_OP: the address to the 0x00 prefix.
7. INT_ACCESSFIELD_OP: the address to the 0x01 prefix.
8. INT_CONNECTION_OP: the address to the 0x02 prefix.
9: INT_EXTACCESSFIELD_OP: the address to the 0x03 prefix.
10.INT_RETURN_VALUE_OP: the address of the replaced operand.
11.computational_data: the address to the
                      Byte/Word/Dword/Qword/string_prefix.

Before cleaning up the internal root scope of the aml_walk, turning it into
the term_list, we need to remember the aml_start address as the "Aml"
attribute for the union acpi_operand_object created by acpi_ps_create_scope_op().

Finally, we can delete some redundant AML address assignment in psloop.c.

1f86e8c1c9 ACPICA: Fix indent caused divergences.
New version of "indent" program will generate different outputs that
will lead to the divergences between the Linux and the ACPICA.
This patch fixes such divergences caused by the "indent" program.
The version of the "indent" used for this patch is "GNU indent 2.2.11".

This patch will not affect the generated vmlinux binary.
This will decrease 581 lines of 20120913 divergence.diff.

2629484288 ACPICA: Fix issues/fault with automatic "serialized" method support
History: This support changes a method to "serialized" on the fly if the
method generates an AE_ALREADY_EXISTS error, indicating the possibility
that it cannot handle reentrancy.

This fix repairs a couple of issues seen in the field, especially on
machines with many cores.

1) Delete method children only upon the exit of the last thread, so
as to not delete objects out from under running threads.

2) Set the "serialized" bit for the method only upon the exit of the
last thread, so as to not cause deadlock when running threads attempt
to exit.

3) Cleanup the use of the AML "MethodFlags" and internal method flags
so that there is no longer any confustion between the two.
