# --------------------------------------------
# 03/09/29	len.brown@intel.com	1.1114
# [ACPI] ACPI Component Architecture 20030918 (Bob Moore)
# 
# Found and fixed a longstanding problem with the late execution of
# the various deferred AML opcodes (such as Operation Regions,
# Buffer Fields, Buffers, and Packages)...
# This fixes the "region size computed incorrectly" problem.
# 
# Fixed several 64-bit issues with prototypes, casting and data types.
# 
# Removed duplicate prototype from acdisasm.h
# --------------------------------------------
