      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.

      Completed a major overhaul of the Resource Manager code -
      specifically, optimizations in the area of the AML/internal
      resource conversion code. The code has been optimized to
      simplify and eliminate duplicated code, CPU stack use has
      been decreased by optimizing function parameters and local
      variables, and naming conventions across the manager have
      been standardized for clarity and ease of maintenance (this
      includes function, parameter, variable, and struct/typedef
      names.)
      
      All Resource Manager dispatch and information tables have
      been moved to a single location for clarity and ease of
      maintenance. One new file was created, named "rsinfo.c".
      
      The ACPI return macros (return_ACPI_STATUS, etc.) have
      been modified to guarantee that the argument is
      not evaluated twice, making them less prone to macro
      side-effects. However, since there exists the possibility
      of additional stack use if a particular compiler cannot
      optimize them (such as in the debug generation case),
      the original macros are optionally available.  Note that
      some invocations of the return_VALUE macro may now cause
      size mismatch warnings; the return_UINT8 and return_UINT32
      macros are provided to eliminate these. (From Randy Dunlap)
      
      Implemented a new mechanism to enable debug tracing for
      individual control methods. A new external interface,
      acpi_debug_trace(), is provided to enable this mechanism. The
      intent is to allow the host OS to easily enable and disable
      tracing for problematic control methods. This interface
      can be easily exposed to a user or debugger interface if
      desired. See the file psxface.c for details.
      
      acpi_ut_callocate() will now return a valid pointer if a
      length of zero is specified - a length of one is used
      and a warning is issued. This matches the behavior of
      acpi_ut_allocate().

      Fixed a problem within the Resource Manager where
      support for the Generic Register descriptor was not fully
      implemented.  This descriptor is now fully recognized,
      parsed, disassembled, and displayed.
      
      Restructured the Resource Manager code to utilize
      table-driven dispatch and lookup, eliminating many of the
      large switch() statements.  This reduces overall subsystem
      code size and code complexity.  Affects the resource parsing
      and construction, disassembly, and debug dump output.
      
      Cleaned up and restructured the debug dump output for all
      resource descriptors.  Improved readability of the output
      and reduced code size.
      
      Fixed a problem where changes to internal data structures
      caused the optional ACPI_MUTEX_DEBUG code to fail
      compilation if specified.

      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!
