      Implemented support to execute Type 1 and Type 2 AML
      opcodes appearing at the module level (not within a control
      method.)  These opcodes are executed exactly once at the
      time the table is loaded. This type of code was legal up
      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.

      Implemented support for PCI Express root bridges
      -- added support for device PNP0A08 in the root
      bridge search within AcpiEvPciConfigRegionSetup.
      acpi_ev_pci_config_region_setup().
      
      The interpreter now automatically truncates incoming
      64-bit constants to 32 bits if currently executing out
      of a 32-bit ACPI table (Revision < 2). This also affects
      the iASL compiler constant folding. (Note: as per below,
      the iASL compiler no longer allows 64-bit constants within
      32-bit tables.)
      
      Fixed a problem where string and buffer objects with
      "static" pointers (pointers to initialization data within
      an ACPI table) were not handled consistently. The internal
      object copy operation now always copies the data to a newly
      allocated buffer, regardless of whether the source object
      is static or not.
      
      Fixed a problem with the FromBCD operator where an
      implicit result conversion was improperly performed while
      storing the result to the target operand. Since this is an
      "explicit conversion" operator, the implicit conversion
      should never be performed on the output.
      
      Fixed a problem with the CopyObject operator where a copy
      to an existing named object did not always completely
      overwrite the existing object stored at name. Specifically,
      a buffer-to-buffer copy did not delete the existing buffer.
      
      Replaced "interrupt_level" with "interrupt_number" in all
      GPE interfaces and structs for consistency.
