What is the purpose of set_vector()?

Hello,

the set_vector() seems to be a pretty weird function. What is the 
purpose of it? It is not clear from the implementations. In particular 
set_vector(..., ..., 0) is only used in five spots:

bsps/m68k/csb360/dev/timer.c:    set_vector(timerisr, BSP_INTVEC_TMR2, 0);
bsps/m68k/mcf5206elite/dev/timer.c:    set_vector(timerisr, 
BSP_INTVEC_TIMER2, 0);
bsps/m68k/mvme167/btimer/btimer.c:  (void) set_vector( timerisr, 
TIMER_VECTOR, 0 );
bsps/m68k/mvme147/btimer/btimer.c:  (void) set_vector(timerisr, 
TIMER_1_VECTOR, 0); /* install ISR */
bsps/m68k/mvme162/btimer/btimer.c:  (void) set_vector( timerisr, VBR0 * 
0x10 + 0x8, 0 );

I think in most cases there is a type mismatch of the handler for type 0 
and not 0.
