modification history
--------------------
01g,17sep99,ms_  remove period in __INCm8260Intr
01f,17sep99,ms_  try removing config.h
01e,15jul99,ms_  make compliant with our coding standards
01d,17apr99,ms_  final EAR cleanup
01c,15apr99,ms_  add default interrupt priority ordering
01b,13apr99,ms_  redefine IVEC_TO_INUM and INUM_TO_IVEC to use the numbers as
                 shown in the 
MPC8260 user's manaul
01a,21jan99,ms_  adapted from ppc860Intr.h
