      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 (These macros have been replaced
      by the ACPI_ERROR and ACPI_WARNING macros.)

      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.

      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.

      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!
