2e5321cb62 ACPICA: Debugger: Cleanup debugging outputs to dump name path without trailing underscores
ACPICA commit 51a49c2fb4a73f302a6df2b8ddc1350dd261684d

It is better to use unified ASL path name to interact with the developers.

This patch cleans up all of the above usages. ACPICA BZ 1178, Lv Zheng.

Linux kernel's ACPICA debugging messages may also be changed.

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.

0bac429552 ACPICA: Dispatcher: Move stack traversal code to dispatcher
ACPICA commit c8275e243b58fd4adfc0362bd704af41ed14bc75

This patch moves parts of acpi_dm_dump_method_info() to the dispatcher
component.

This patch also makes the new function dependent on ACPI_DEBUG_OUTPUT
compile-stage definition so that it can be used by the trace facility.

acpi_dm_dump_method_info() traverses method stack when an exception is
encountered. Such traversal is needed to support method tracing for the
exceptions. When an exception is encountered, the end indications of the
aborted methods should be logged in order not to break the user space
analysis tool. Lv Zheng.
