This is already cleaned up (the mpc55xx was the first BSP that uses this, it is
required here due to the nearly 400 interrupt sources):

http://www.rtems.com/doxygen/cpukit/html/group__rtems__interrupt__extension.html

./cpukit/include/rtems/irq-extension.h

./c/src/lib/libbsp/shared/include/irq-config.h


./c/src/lib/libbsp/shared/include/irq-info.h


./c/src/lib/libbsp/shared/include/irq-generic.h

./c/src/lib/libbsp/shared/src/irq-shell.c


./c/src/lib/libbsp/shared/src/irq-legacy.c


./c/src/lib/libbsp/shared/src/irq-generic.c


./c/src/lib/libbsp/shared/src/irq-info.c
./c/src/lib/libbsp/shared/src/irq-server.c

The interrupt handler type will change in the near future from

typedef void(*rtems_interrupt_handler)(rtems_vector_number, void *);

to

typedef void(*rtems_interrupt_handler)(void *);

or a union that contains the type above.
