Bob Moore 6c9deb7201 ACPICA: Update copyright to 2007.
Added 2007 copyright to all module headers and signons. This affects
virtually every file in the ACPICA core subsystem, iASL compiler,
and the utilities.

Restructured, flattened, and simplified the internal
interfaces for namespace object evaluation - resulting
in smaller code, less CPU stack use, and fewer
interfaces. (With assistance from Mikhail Kouzmich)

Fixed a problem with the CopyObject operator where the
first parameter was not typed correctly for the parser,
interpreter, compiler, and disassembler. Caused various
errors and unexpected behavior.

Fixed a problem where a ShiftLeft or ShiftRight of
more than 64 bits produced incorrect results with some
C compilers. Since the behavior of C compilers when
the shift value is larger than the datatype width is
apparently not well defined, the interpreter now detects
this condition and simply returns zero as expected in all
such cases. (BZ 395)

Fixed problem reports (Valery Podrezov) integrated: -
Update String-to-Integer conversion to match ACPI 3.0A spec
http://bugzilla.kernel.org/show_bug.cgi?id=5329
Allow interpreter to handle nested method declarations
http://bugzilla.kernel.org/show_bug.cgi?id=5361

Fixed problem reports (Fiodor Suietov) integrated: -
acpi_terminate() doesn't free debug memory allocation
list objects (BZ 355) - After Core Subsystem
shutdown, acpi_subsystem_status() returns AE_OK (BZ 356) -
acpi_os_unmap_memory() for RSDP can be invoked inconsistently
(BZ 357) - Resource Manager should return AE_TYPE for
non-device objects (BZ 358) - Incomplete cleanup branch
in AcpiNsEvaluateRelative (BZ 359) - Use acpi_os_free()
instead of ACPI_FREE in acpi_rs_set_srs_method_data (BZ 360)
- Incomplete cleanup branch in acpi_ps_parse_aml (BZ 361) -
Incomplete cleanup branch in acpi_ds_delete_walk_state (BZ 362)
- acpi_get_table_header returns AE_NO_ACPI_TABLES until DSDT
is loaded (BZ 365) - Status of the Global Initialization
Handler call not used (BZ 366) - Incorrect object parameter
to Global Initialization Handler (BZ 367)

Bob Moore 8313524a0d ACPI: ACPICA 20060310
Tagged all external interfaces to the subsystem with the
new ACPI_EXPORT_SYMBOL macro. This macro can be defined
as necessary to assist kernel integration. For Linux,
the macro resolves to the EXPORT_SYMBOL macro. The default
definition is NULL.

Added the ACPI_THREAD_ID type for the return value from
acpi_os_get_thread_id(). This allows the host to define this
as necessary to simplify kernel integration. The default
definition is ACPI_NATIVE_UINT.

Valery Podrezov fixed two interpreter problems related
to error processing, the deletion of objects, and placing
invalid pointers onto the internal operator result stack.

http://bugzilla.kernel.org/show_bug.cgi?id=6151

Increased the reference count threshold where a warning is
emitted for large reference counts in order to eliminate
unnecessary warnings on systems with large namespaces
(especially 64-bit.) Increased the value from 0x400
to 0x800.

Due to universal disagreement as to the meaning of the
'c' in the calloc() function, the ACPI_MEM_CALLOCATE
macro has been renamed to ACPI_ALLOCATE_ZEROED so that the
purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and
ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.

Removed a couple of extraneous ACPI_ERROR messages that
appeared during normal execution. These became apparent
after the conversion from ACPI_DEBUG_PRINT.

Fixed a problem where the CreateField operator could hang
if the BitIndex or NumBits parameter referred to a named
object. From Valery Podrezov.

Fixed a problem where a DeRefOf operation on a buffer
object incorrectly failed with an exception. This also
fixes a couple of related RefOf and DeRefOf issues.

Index() operation. From Valery Podrezov.

Implemented a memory cleanup at the end of the execution
of each iteration of an AML While() loop, preventing the
accumulation of outstanding objects. From Valery Podrezov.

Bob Moore b8e4d89357 [ACPI] ACPICA 20060127
Implemented support in the Resource Manager to allow
unresolved namestring references within resource package
objects for the _PRT method. This support is in addition
to the previously implemented unresolved reference
support within the AML parser. If the interpreter slack
mode is enabled (true on Linux unless acpi=strict),
these unresolved references will be passed through
to the caller as a NULL package entry.
http://bugzilla.kernel.org/show_bug.cgi?id=5741

Implemented and deployed new macros and functions for
error and warning messages across the subsystem. These
macros are simpler and generate less code than their
predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION,
ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_*
macros.

Implemented the acpi_cpu_flags type to simplify host OS
integration of the Acquire/Release Lock OSL interfaces.
Suggested by Steven Rostedt and Andrew Morton.

Fixed a problem where Alias ASL operators are sometimes
not correctly resolved. causing AE_AML_INTERNAL
http://bugzilla.kernel.org/show_bug.cgi?id=5189
http://bugzilla.kernel.org/show_bug.cgi?id=5674

Fixed several problems with the implementation of the
ConcatenateResTemplate ASL operator. As per the ACPI
specification, zero length buffers are now treated as a
single EndTag. One-length buffers always cause a fatal
exception. Non-zero length buffers that do not end with
a full 2-byte EndTag cause a fatal exception.

Fixed a possible structure overwrite in the
AcpiGetObjectInfo external interface. (With assistance
from Thomas Renninger)

Bob Moore 4a90c7e862 [ACPI] ACPICA 20060113
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.

Robert Moore 44f6c01242 ACPICA 20050408 from Bob Moore
Fixed three cases in the interpreter where an "index"
argument to an ASL function was still (internally) 32
bits instead of the required 64 bits.  This was the Index
argument to the Index, Mid, and Match operators.

The "strupr" function is now permanently local
(acpi_ut_strupr), since this is not a POSIX-defined
function and not present in most kernel-level C
libraries. References to the C library strupr function
have been removed from the headers.

Completed the deployment of static
functions/prototypes. All prototypes with the static
attribute have been moved from the headers to the owning
C file.

ACPICA 20050329 from Bob Moore

An error is now generated if an attempt is made to create
a Buffer Field of length zero (A CreateField with a length
operand of zero.)

The interpreter now issues a warning whenever executable
code at the module level is detected during ACPI table
load. This will give some idea of the prevalence of this
type of code.

Implemented support for references to named objects (other
than control methods) within package objects.

Enhanced package object output for the debug
object. Package objects are now completely dumped, showing
all elements.

Enhanced miscellaneous object output for the debug
object. Any object can now be written to the debug object
(for example, a device object can be written, and the type
of the object will be displayed.)

The "static" qualifier has been added to all local
functions across the core subsystem.

The number of "long" lines (> 80 chars) within the source
has been significantly reduced, by about 1/3.

Cleaned up all header files to ensure that all CA/iASL
functions are prototyped (even static functions) and the
formatting is consistent.

Two new header files have been added, acopcode.h and
acnames.h.

Removed several obsolete functions that were no longer
used.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
