  ACPICA: Interpreter: Add additional debug info for an error case.
  ACPICA: Update ACPI example code to make it an actual working program.
  ACPICA: Add an error message if the Debugger fails initialization.
  ACPICA: Conditionally define a local variable that is used for debug only.
  ACPICA: Parser: Updates/fixes for debug output.
  ACPICA: Enhance ACPI warning for memory/IO address conflicts.
  ACPICA: Update several debug statements - no functional change.
  ACPICA: Improve exception handling for GPE block installation.
  ACPICA: Add helper macros to extract bus/segment numbers from HEST table.
  ACPICA: Tables: Add full support for the PCCT table, update table definition.
  ACPICA: Tables: Add full support for the DBG2 table.
  ACPICA: Add option to favor 32-bit FADT addresses.
  ACPICA: Cleanup the option of forcing the use of the RSDT.
  ACPICA: Back port and refine validation of the XSDT root table.
  ACPICA: Linux Header: Remove unused OSL prototypes.
  ACPICA: Remove unused ACPI_FREE_BUFFER macro. No functional change.
  ACPICA: Disassembler: Improve pathname support for emitted External() statements.

* 32-bit V1.0 fields to the 64-bit X fields if the the 64-bit X field is

* fields are expanded to the corresponding 64-bit X fields in the internal
* common FADT.
*
* For ACPI 2.0+ FADTs, all valid (non-zero) 32-bit address fields are expanded
* to the corresponding 64-bit X fields. For compatibility with other ACPI
* implementations, we ignore the 64-bit field if the 32-bit field is valid,
