From 7d91bda6bfba1bd0cf49ff7ff20373b5d44df87a Mon Sep 17 00:00:00 2001
From: Nathan Binkert <binkertn@umich.edu>

Subject: Add support for using the variables that m5 was compiled with for
 determining which parameters belong to a class.  This allows us to remove the
 disable flag since it is not the correct model for variable checking anyway.

objects/BaseCPU.mpy:
    Use the FULL_SYSTEM environment variable to enable or disable
    parameters.
sim/pyconfig/m5config.py:
    remove the disable flag since it is not the correct model
    for variable checking.
