This patch enables ACPICA debugger files using a configurable
CONFIG_ACPI_DEBUGGER configuration item. Those debugger related code that
was originally masked as ACPI_FUTURE_USAGE now gets unmasked.
Necessary OSL stubs are also added in this patch:
1. acpi_os_readable(): This should be arch specific in Linux, while this
patch doesn't introduce real implementation and a complex mechanism to
allow architecture specific acpi_os_readable() to be implemented to
validate the address. It may be done by future commits.
2. acpi_os_get_line(): This is used to obtain debugger command input. This
patch only introduces a simple KDB concept example in it and the
example should be co-working with the code implemented in
acpi_os_printf(). Since this KDB example won't be compiled unless
ENABLE_DEBUGGER is defined and it seems Linux has already stopped to
use ENABLE_DEBUGGER, thus do not expect it can work properly.
This patch also cleans up all other ACPI_FUTURE_USAGE surroundings
accordingly.
1. Since linkage error can be automatically detected, declaration in the
headers needn't be surrounded by ACPI_FUTURE_USAGE.
So only the following separate exported fuction bodies are masked by
this macro (other exported fucntions may have already been masked at
entire module level via drivers/acpi/acpica/Makefile):
acpi_install_exception_handler()
acpi_subsystem_status()
acpi_get_system_info()
acpi_get_statistics()
acpi_install_initialization_handler()
2. Since strip can automatically zap the no-user functions, functions that
are not marked with ACPI_EXPORT_SYMBOL() needn't get surrounded by
ACPI_FUTURE_USAGE.
So the following function which is not used by Linux kernel now won't
get surrounded by this macro:
acpi_ps_get_name()

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.

ACPICA commit 47d22a738d0e19fd241ffe4e3e9d4e198e4afc69
Across all of ACPICA. Replace C library macros such as ACPI_STRLEN with the
standard names such as strlen. The original purpose for these macros is
long since obsolete.
Also cast various invocations as necessary. Bob Moore, Jung-uk Kim, Lv Zheng.

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.

Fixes issues like this:
i_aSL -> iASL
00-7_f -> 00-7F
local_fADT -> local_FADT
execute_oSI -> execute_OSI
Also, in function headers, the parameters are now translated to
lower case (with underscores if necessary.)
