No, you are absolutely right! I should have looked more attentively.

Is "IL" good enough for a decoded reason

 	{ARM_EXCEPTION_IRQ,		"IRQ"		},	\
 	{ARM_EXCEPTION_EL1_SERROR,	"SERROR"	},	\
 	{ARM_EXCEPTION_TRAP,		"TRAP"		},	\
+	{ARM_EXCEPTION_IL,		"IL"		}, \
 	{ARM_EXCEPTION_HYP_GONE,	"HYP_GONE"	}

or should there be "ILLEGAL", or maybe something even better?
ILLEGAL_EXC, etc.
