--------------------
01g,30nov11,h_k  avoided conflict with interrupt controller driver specific
                 IVEC_TO_INUM and INUM_TO_IVEC. (WIND00124986)
01f,04nov03,kam  ISR Object code inspection mods
01e,09dec96,tpr  changed _func_intEnableRtn() & _func_intDisableRtn() return
		 type from void to int.
01d,17jun96,tpr  added _func_intXXX prototype.
01c,17jun96,tam  used "INUM_TO_IVEC" instead of "IVEC_TO_INUM" for the PPC403
		 interrupt vector definitions (spr #6017).
01b,02feb95,yao  added vector definition for PPC403.
01a,29may87,yao  written.
