      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)

      Removed a device initialization optimization introduced in
      20051216 where the _STA method was not run unless an _INI
      was also present for the same device. This optimization
      could cause problems because it could allow _INI methods
      to be run within a not-present device subtree (If a
      not-present device had no _INI, _STA would not be run,
      the not-present status would not be discovered, and the
      children of the device would be incorrectly traversed.)
      
      Implemented a new _STA optimization where namespace
      subtrees that do not contain _INI are identified and
      ignored during device initialization. Selectively running
      _STA can significantly improve boot time on large machines
      (with assistance from Len Brown.)
      
      Implemented support for the device initialization case
      where the returned _STA flags indicate a device not-present
      but functioning. In this case, _INI is not run, but the
      device children are examined for presence, as per the
      ACPI specification.
      
      Implemented an additional change to the IndexField support
      in order to conform to MS behavior. The value written to
      the Index Register is not simply a byte offset, it is a
      byte offset in units of the access width of the parent
      Index Field. (Fiodor Suietov)
      
      Defined and deployed a new OSL interface,
      acpi_os_validate_address().  This interface is called during
      the creation of all AML operation regions, and allows
      the host OS to exert control over what addresses it will
      allow the AML code to access. Operation Regions whose
      addresses are disallowed will cause a runtime exception
      when they are actually accessed (will not affect or abort
      table loading.)
      
      Defined and deployed a new OSL interface,
      acpi_os_validate_interface().  This interface allows the host OS
      to match the various "optional" interface/behavior strings
      for the _OSI predefined control method as appropriate
      (with assistance from Bjorn Helgaas.)
      
      Restructured and corrected various problems in the
      exception handling code paths within DsCallControlMethod
      and DsTerminateControlMethod in dsmethod (with assistance
      from Takayoshi Kochi.)
      
      Modified the Linux source converter to ignore quoted string
      literals while converting identifiers from mixed to lower
      case. This will correct problems with the disassembler
      and other areas where such strings must not be modified.
      
      The ACPI_FUNCTION_* macros no longer require quotes around
      the function name. This allows the Linux source converter
      to convert the names, now that the converter ignores
      quoted strings.

      Implemented the use of a cache object for all internal
      namespace nodes. Since there are about 1000 static nodes
      in a typical system, this will decrease memory use for
      cache implementations that minimize per-allocation overhead
      (such as a slab allocator.)
      
      Removed the reference count mechanism for internal
      namespace nodes, since it was deemed unnecessary. This
      reduces the size of each namespace node by about 5%-10%
      on all platforms. Nodes are now 20 bytes for the 32-bit
      case, and 32 bytes for the 64-bit case.
      
      Optimized several internal data structures to reduce
      object size on 64-bit platforms by packing data within
      the 64-bit alignment. This includes the frequently used
      ACPI_OPERAND_OBJECT, of which there can be ~1000 static
      instances corresponding to the namespace objects.
      
      Added two new strings for the predefined _OSI method:
      "Windows 2001.1 SP1" and "Windows 2006".
      
      Split the allocation tracking mechanism out to a separate
      file, from utalloc.c to uttrack.c. This mechanism appears
      to be only useful for application-level code. Kernels may
      wish to not include uttrack.c in distributions.
      
      Removed all remnants of the obsolete ACPI_REPORT_* macros
      and the associated code. (These macros have been replaced
      by the ACPI_ERROR and ACPI_WARNING macros.)

      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.

      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.

      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

      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.

      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.

      Implemented support to ignore an attempt to install/load
      a particular ACPI table more than once. Apparently there
      exists BIOS code that repeatedly attempts to load the same
      SSDT upon certain events. Thanks to Venkatesh Pallipadi.
      
      Restructured the main interface to the AML parser in
      order to correctly handle all exceptional conditions. This
      will prevent leakage of the OwnerId resource and should
      eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
      machines. Thanks to Alexey Starikovskiy.
      
      Support for "module level code" has been disabled in this
      version due to a number of issues that have appeared
      on various machines. The support can be enabled by
      defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
      compilation. When the issues are fully resolved, the code
      will be enabled by default again.
      
      Modified the internal functions for debug print support
      to define the FunctionName parameter as a (const char *)
      for compatibility with compiler built-in macros such as
      __FUNCTION__, etc.

      ACPICA 20050617:
      
      Moved the object cache operations into the OS interface
      layer (OSL) to allow the host OS to handle these operations
      if desired (for example, the Linux OSL will invoke the
      slab allocator).  This support is optional; the compile
      time define ACPI_USE_LOCAL_CACHE may be used to utilize
      the original cache code in the ACPI CA core.  The new OSL
      interfaces are shown below.  See utalloc.c for an example
      implementation, and acpiosxf.h for the exact interface
      definitions.  Thanks to Alexey Starikovskiy.
      	acpi_os_create_cache
      	acpi_os_delete_cache
      	acpi_os_purge_cache
      	acpi_os_acquire_object
      	acpi_os_release_object
      
      Modified the interfaces to acpi_os_acquire_lock and
      acpi_os_release_lock to return and restore a flags
      parameter.  This fits better with many OS lock models.
      Note: the current execution state (interrupt handler
      or not) is no longer passed to these interfaces.  If
      necessary, the OSL must determine this state by itself, a
      simple and fast operation.  Thanks to Alexey Starikovskiy.
      
      Fixed a problem in the ACPI table handling where a valid
      XSDT was assumed present if the revision of the RSDP
      was 2 or greater.  According to the ACPI specification,
      the XSDT is optional in all cases, and the table manager
      therefore now checks for both an RSDP >=2 and a valid
      XSDT pointer.  Otherwise, the RSDT pointer is used.
      Some ACPI 2.0 compliant BIOSs contain only the RSDT.
      
      Fixed an interpreter problem with the Mid() operator in the
      case of an input string where the resulting output string
      is of zero length.  It now correctly returns a valid,
      null terminated string object instead of a string object
      with a null pointer.
      
      Fixed a problem with the control method argument handling
      to allow a store to an Arg object that already contains an
      object of type Device.  The Device object is now correctly
      overwritten.  Previously, an error was returned.
      
      ACPICA 20050624:
      
      Modified the new OSL cache interfaces to use ACPI_CACHE_T
      as the type for the host-defined cache object.  This allows
      the OSL implementation to define and type this object in
      any manner desired, simplifying the OSL implementation.
      For example, ACPI_CACHE_T is defined as kmem_cache_t for
      Linux, and should be defined in the OS-specific header
      file for other operating systems as required.
      
      Changed the interface to AcpiOsAcquireObject to directly
      return the requested object as the function return (instead
      of ACPI_STATUS.) This change was made for performance
      reasons, since this is the purpose of the interface in the
      first place.  acpi_os_acquire_object is now similar to the
      acpi_os_allocate interface.  Thanks to Alexey Starikovskiy.
      
      Modified the initialization sequence in
      acpi_initialize_subsystem to call the OSL interface
      acpi_osl_initialize first, before any local initialization.
      This change was required because the global initialization
      now calls OSL interfaces.
      
      Restructured the code base to split some files because
      of size and/or because the code logically belonged in a
      separate file.  New files are listed below.
      
        utilities/utcache.c	/* Local cache interfaces */

      Implemented support to execute Type 1 and Type 2 AML
      opcodes appearing at the module level (not within a control
      method.)  These opcodes are executed exactly once at the
      time the table is loaded. This type of code was legal up
      until the release of ACPI 2.0B (2002) and is now supported
      within ACPI CA in order to provide backwards compatibility
      with earlier BIOS implementations. This eliminates the
      "Encountered executable code at module level" warning that
      was previously generated upon detection of such code.
      
      Fixed a problem in the interpreter where an AE_NOT_FOUND
      exception could inadvertently be generated during the
      lookup of namespace objects in the second pass parse of
      ACPI tables and control methods. It appears that this
      problem could occur during the resolution of forward
      references to namespace objects.
      
      Added the ACPI_MUTEX_DEBUG #ifdef to the
      acpi_ut_release_mutex function, corresponding to the same
      the deadlock detection debug code to be compiled out in
      the normal case, improving mutex performance (and overall
      subsystem performance) considerably.  As suggested by
      Alexey Starikovskiy.
      
      Implemented a handful of miscellaneous fixes for possible
      memory leaks on error conditions and error handling
      control paths. These fixes were suggested by FreeBSD and
      the Coverity Prevent source code analysis tool.
      
      Added a check for a null RSDT pointer in
      acpi_get_firmware_table (tbxfroot.c) to prevent a fault
      in this error case.

      The interpreter now automatically truncates incoming
      64-bit constants to 32 bits if currently executing out
      of a 32-bit ACPI table (Revision < 2). This also affects
      the iASL compiler constant folding. (Note: as per below,
      the iASL compiler no longer allows 64-bit constants within
      32-bit tables.)
      
      Fixed a problem where string and buffer objects with
      "static" pointers (pointers to initialization data within
      an ACPI table) were not handled consistently. The internal
      object copy operation now always copies the data to a newly
      allocated buffer, regardless of whether the source object
      is static or not.
      
      Fixed a problem with the FromBCD operator where an
      implicit result conversion was improperly performed while
      storing the result to the target operand. Since this is an
      "explicit conversion" operator, the implicit conversion
      should never be performed on the output.
      
      Fixed a problem with the CopyObject operator where a copy
      to an existing named object did not always completely
      overwrite the existing object stored at name. Specifically,
      a buffer-to-buffer copy did not delete the existing buffer.

      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.

      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!
