      Implemented a new acpi_spinlock type for the OSL lock
      interfaces.  This allows the type to be customized to
      the host OS for improved efficiency (since a spinlock is
      usually a very small object.)
      
      Implemented support for "ignored" bits in the ACPI
      registers.  According to the ACPI specification, these
      bits should be preserved when writing the registers via
      a read/modify/write cycle. There are 3 bits preserved
      in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
      and PM1_STATUS[11].
      http://bugzilla.kernel.org/show_bug.cgi?id=3691
      
      Implemented the initial deployment of new OSL mutex
      interfaces.  Since some host operating systems have
      separate mutex and semaphore objects, this feature was
      requested. The base code now uses mutexes (and the new
      mutex interfaces) wherever a binary semaphore was used
      previously. However, for the current release, the mutex
      interfaces are defined as macros to map them to the
      existing semaphore interfaces.
      
      Fixed several problems with the support for the control
      method SyncLevel parameter. The SyncLevel now works
      according to the ACPI specification and in concert with the
      Mutex SyncLevel parameter, since the current SyncLevel is
      a property of the executing thread. Mutual exclusion for
      control methods is now implemented with a mutex instead
      of a semaphore.
      
      Fixed three instances of the use of the C shift operator
      in the bitfield support code (exfldio.c) to avoid the use
      of a shift value larger than the target data width. The
      behavior of C compilers is undefined in this case and can
      cause unpredictable results, and therefore the case must
      be detected and avoided.  (Fiodor Suietov)
      
      Added an info message whenever an SSDT or OEM table
      is loaded dynamically via the Load() or LoadTable()
      ASL operators. This should improve debugging capability
      since it will show exactly what tables have been loaded
      (beyond the tables present in the RSDT/XSDT.)

      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      this appeared to be useless and has been replaced by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

      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.

      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

      definition is ACPI_NATIVE_UINT.

      'c' in the calloc() function, the ACPI_MEM_CALLOCATE
      macro has been renamed to ACPI_ALLOCATE_ZEROED so that the

      flag which Linux has enabled by default (acpi=strict

      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

      exceptions seen on some machines where reentrant control
      methods are protected by an AML mutex. The mutex will now

      Fixed a problem in the AML parser where the method thread
      count could be decremented below zero if any errors

      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.

      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_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.

      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.

      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
      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!
