      Converted the locking mutex used for the ACPI hardware
      to a spinlock. This change should eliminate all problems
      caused by attempting to acquire a semaphore at interrupt
      level, and it means that all ACPICA external interfaces
      that directly access the ACPI hardware can be safely
      called from interrupt level.
      Fixed a regression introduced in 20060526 where the ACPI
      device initialization could be prematurely aborted with
      an AE_NOT_FOUND if a device did not have an optional
      _INI method.
      Fixed an IndexField issue where a write to the Data
      Register should be limited in size to the AccessSize
      (width) of the IndexField itself. (BZ 433, Fiodor Suietov)
      Fixed problem reports (Valery Podrezov) integrated: - Allow
      store of ThermalZone objects to Debug object.
      Fixed problem reports (Fiodor Suietov) integrated: -
      acpi_get_table_header() doesn't handle multiple instances
      correctly (BZ 364)
      Removed four global mutexes that were obsolete and were
      no longer being used.

      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 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)

      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.
      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_*
      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
      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)

      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
      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.

      Fixed a problem in the AML parser where the method thread
      count could be decremented below zero if any errors
      occurred during the method parse phase. This should
      eliminate AE_AML_METHOD_LIMIT exceptions seen on some
      machines. This also fixed a related regression with the
      mechanism that detects and corrects methods that cannot
      properly handle reentrancy (related to the deployment of
      the new OwnerId mechanism.)
      Eliminated the pre-parsing of control methods (to detect
      errors) during table load. Related to the problem above,
      this was causing unwind issues if any errors occurred
      during the parse, and it seemed to be overkill. A table
      load should not be aborted if there are problems with
      any single control method, thus rendering this feature
      rather pointless.
      Fixed a problem with the new table-driven resource manager
      where an internal buffer overflow could occur for small
      resource templates.
      Implemented a new external interface, acpi_get_vendor_resource()
      This interface will find and return a vendor-defined
      resource descriptor within a _CRS or _PRS
      method via an ACPI 3.0 UUID match. (from Bjorn Helgaas)
      Removed the length limit (200) on string objects as
      per the upcoming ACPI 3.0A specification. This affects
      the following areas of the interpreter: 1) any implicit
      conversion of a Buffer to a String, 2) a String object
      result of the ASL Concatentate operator, 3) the String
      object result of the ASL ToString operator.

      Implemented support for the EM64T and other x86_64
      processors. This essentially entails recognizing
      that these processors support non-aligned memory
      transfers. Previously, all 64-bit processors were assumed
      to lack hardware support for non-aligned transfers.
      Completed conversion of the Resource Manager to nearly
      full table-driven operation. Specifically, the resource
      conversion code (convert AML to internal format and the
      reverse) and the debug code to dump internal resource
      descriptors are fully table-driven, reducing code and data
      size and improving maintainability.
      The OSL interfaces for Acquire and Release Lock now use a
      64-bit flag word on 64-bit processors instead of a fixed
      32-bit word. (Alexey Starikovskiy)
      Implemented support within the resource conversion code
      for the Type-Specific byte within the various ACPI 3.0
      *WordSpace macros.
      Fixed some issues within the resource conversion code for
      the type-specific flags for both Memory and I/O address
      resource descriptors. For Memory, implemented support
      for the MTP and TTP flags. For I/O, split the TRS and TTP
      flags into two separate fields.

      Implemented a full bytewise compare to determine if a table load
      request is attempting to load a duplicate table. The compare is
      performed if the table signatures and table lengths match. This
      will allow different tables with the same OEM Table ID and
      revision to be loaded.
      Although the BIOS is technically violating the ACPI spec when
      this happens -- it does happen -- so Linux must handle it.

      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.
      Linted the entire ACPICA source tree for both 32-bit
      and 64-bit.

      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.

      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
      Removed several obsolete functions that were no longer

      Initial git repository build. I'm not bothering with the full history,
