      The use of the CPU stack in the debug version of the
      subsystem has been considerably reduced.  Previously, a
      debug structure was declared in every function that used
      the debug macros.  This structure has been removed in
      favor of declaring the individual elements as parameters
      to the debug functions.  This reduces the cumulative stack
      use during nested execution of ACPI function calls at the
      cost of a small increase in the code size of the debug
      version of the subsystem.  With assistance from Alexey
      Starikovskiy and Len Brown.
      
      Added the ACPI_GET_FUNCTION_NAME macro to enable the
      compiler-dependent headers to define a macro that will
      return the current function name at runtime (such as
      __FUNCTION__ or _func_, etc.) The function name is used
      by the debug trace output.  If ACPI_GET_FUNCTION_NAME
      is not defined in the compiler-dependent header, the
      function name is saved on the CPU stack (one pointer per
      function.) This mechanism is used because apparently there
      exists no standard ANSI-C defined macro that that returns
      the function name.
      
      Alexey Starikovskiy redesigned and reimplemented the
      "Owner ID" mechanism used to track namespace objects
      created/deleted by ACPI tables and control method
      execution.  A bitmap is now used to allocate and free the
      IDs, thus solving the wraparound problem present in the
      previous implementation.  The size of the namespace node
      descriptor was reduced by 2 bytes as a result.
      
      Removed the UINT32_BIT and UINT16_BIT types that were used
      for the bitfield flag definitions within the headers for
      the predefined ACPI tables.  These have been replaced by
      UINT8_BIT in order to increase the code portability of
      the subsystem.  If the use of UINT8 remains a problem,
      we may be forced to eliminate bitfields entirely because
      of a lack of portability.
      
      Alexey Starikovksiy enhanced the performance of
      acpi_ut_update_object_reference.  This is a frequently used
      function and this improvement increases the performance
      of the entire subsystem.
      
      Alexey Starikovskiy fixed several possible memory leaks
      and the inverse - premature object deletion.

      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 */
        utilities/utmutex.c	/* Local mutex support */
        utilities/utstate.c	/* State object support */
        parser/psloop.c	/* Main AML parse loop */

      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!
