Bob Moore 6ea8c546f3 ACPICA: FADT support cleanup
ACPICA commit 34ccd43af3fd1870fddfac0617dd0ba706963558

Remove all vestiges of the version 2 FADT which never was included
in the ACPI specification.

This enabled significant cleanup of both the data table compiler
and the disassembler.

Added many clarification comments to associate each FADT version
with the version of the ACPI spec where it was originally
defined.

Lv Zheng 8a216d7f6a ACPICA: Tables: Cleanup ACPI_TABLE_ORIGIN_xxx flags.
This patch refines ACPI_TABLE_ORIGIN_xxx flags.  No functional changes.

The previous commits have introduced the following internal APIs:
1. acpi_tb_acquire_table: Acquire struct acpi_table_header according to
                       ACPI_TABLE_ORIGIN_xxx flags.
2. acpi_tb_release_table: Release struct acpi_table_header according to
                       ACPI_TABLE_ORIGIN_xxx flags.
3. acpi_tb_install_table: Make struct acpi_table_desc.Address not NULL according to
                       ACPI_TABLE_ORIGIN_xxx flags.
4. acpi_tb_uninstall_table: Make struct acpi_table_desc.Address NULL according to
                         ACPI_TABLE_ORIGIN_xxx flags.
5. acpi_tb_validate_table: Make struct acpi_table_desc.Pointer not NULL according to
                        ACPI_TABLE_ORIGIN_xxx flags.
6. acpi_tb_invalidate_table: Make struct acpi_table_desc.Pointer NULL according to
                          ACPI_TABLE_ORIGIN_xxx flags.
It thus detects that the ACPI_TABLE_ORIGIN_UNKNOWN is redundant to
ACPI_TABLE_ORIGIN_OVERRIDE.

The ACPI_TABLE_ORIGIN_xxTERN_VIRTUAL flags are named as VIRTUAL in order
not to confuse with x86 logical address, this patch also renames all
"logical override" into "virtual override".

Bob Moore 4ac4c5fad8 ACPICA: Headers: Deploy #pragma pack (push) and (pop).
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, but 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.

Lv Zheng 671cc68dc6 ACPICA: Back port and refine validation of the XSDT root table.
Some platforms contain an XSDT that is ill-formed or otherwise invalid
(such as containing some or all entries that are NULL pointers).
This change adds a new function to validate the XSDT before actually
using it. If the XSDT is found to be invalid, ACPICA will now fall
back to using the RSDT instead.

This feature is already in the Linux kernel.  When it is back ported to
ACPICA, code is refined to follow ACPICA coding style and this patch
is the generation of the integration.

Lv Zheng 3e8214e5c2 ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA.
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.

3. Repositioning of the code blocks.
4. Replacing the values with the well defined macros.

Bob Moore be030a5768 ACPICA: Add support for complex _PLD buffers.
_PLD (Physical Location of Device) returns a bit-packed buffer that
is difficult to parse. This change adds a new interface,
AcpiDecodePldBuffer that parses the buffer into a more usable
local struct. Also adds macros to both get and set individual
fields within the packed _PLD buffer. Adds a new include file,
acbuffer.h - which will be expanded to add structs for other
ACPI names that return buffers. ACPICA BZ 954.

Emit (in comments) the decoded contents of a static _PLD buffer
in order to improve comprehension of this bit-packed buffer.

Add multi-endian support to the _PLD decode routine. Deploy the
multi-endian macros to extract data from the _PLD buffer.

Bob Moore 958dd242b6 ACPI: ACPICA 20060512
Replaced the acpi_os_queue_for_execution() with a new
interface named acpi_os_execute(). The major difference is
that the new interface does not have a Priority parameter,
this appeared to be useless and has been replaced by
a Type parameter. The Type tells the OS what type of
execution is being requested, such as global lock handler,
notify handler, GPE handler, etc. This allows the host
to queue and execute the request as appropriate for the
request type, possibly using different work queues and
different priorities for the various request types. This
enables fixes for multithreading deadlock problems such as

Fixed a possible memory leak associated with the
support for the so-called "implicit return" ACPI
extension. Reported by FreeBSD  (Fiodor Suietov)
http://bugzilla.kernel.org/show_bug.cgi?id=6514

Fixed a problem with the Load() operator where a table
load from an operation region could overwrite an internal
table buffer by up to 7 bytes and cause alignment faults
on IPF systems. (With assistance from Luming Yu)

Bob Moore 793c2388ca ACPI: ACPICA 20060331
Implemented header file support for the following
additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
SPMI, TCPA, and WDRT. With this support, all current and
known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.

Implemented support to allow tables that contain ACPI
names with invalid characters to be loaded. Previously,
this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the
behavior of the Microsoft ACPI implementation.

Fixed a couple regressions introduced during the memory
optimization in the 20060317 release. The namespace
node definition required additional reorganization and
an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)

Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object().  (Valery Podrezov,
Fiodor Suietov)

Fixed a memory mapping leak during the deletion of
a SystemMemory operation region where a cached memory
mapping was not deleted. This became a noticeable problem
for operation regions that are defined within frequently
used control methods. (Dana Meyers)

Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,
and another for the miscellaneous ACPI tables that are
consumed by the drivers and other software. The various
FADT definitions were merged into one common section and
three different tables (ACPI 1.0, 1.0+, and 2.0)

Added 2006 copyright.

At SuSE's suggestion, enabled all error messages
without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n

Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages
in the non-debug version of the ACPICA code (this has been
referred to as the "debug lite" option.) Over 200 cases
were converted to create a total of over 380 error/warning
messages across the ACPICA code. This increases the code
and data size of the default non-debug version by about 13K.
Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
The size of the debug version remains about the same.

Bob Moore defba1d8f2 [ACPI] ACPICA 20051216
Implemented optional support to allow unresolved names
within ASL Package objects. A null object is inserted in
the package when a named reference cannot be located in
the current namespace. Enabled via the interpreter slack
flag which Linux has enabled by default (acpi=strict
to disable slack).  This should eliminate AE_NOT_FOUND
exceptions seen on machines that contain such code.

Implemented an optimization to the initialization
sequence that can improve boot time. During ACPI device
initialization, the _STA method is now run if and only
if the _INI method exists. The _STA method is used to
determine if the device is present; An _INI can only be
run if _STA returns present, but it is a waste of time to
run the _STA method if the _INI does not exist. (Prototype
and assistance from Dong Wei)

Implemented use of the C99 uintptr_t for the pointer
casting macros if it is available in the current
compiler. Otherwise, the default (void *) cast is used
as before.

Fixed some possible memory leaks found within the
execution path of the Break, Continue, If, and CreateField
operators. (Valery Podrezov)

Fixed a problem introduced in the 20051202 release where
an exception is generated during method execution if a
control method attempts to declare another method.
