Merge branch 'acpica'
* acpica: (21 commits) ACPICA: Update version to 20131218. ACPICA: Utilities: Cleanup declarations of the acpi_gbl_debug_file global. ACPICA: Linuxize: Cleanup spaces after special macro invocations. 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.
