From 1044f1f65b7df2aae979e397904c4985eeb99ba2 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Sat, 27 Sep 2008 11:08:41 +0800 Subject: ACPICA: Cleanup for internal Reference Object Fix some sloppiness in the Reference object. No longer use AML opcodes to differentiate the types, introduce new reference Class. Cleanup the debug output code.
