Subject[PATCH - RESUBMiT] Minor patch to pvr2 driver required for maple bus support on SEGA Dreamcast
The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware
synchronisation between the maple bus and the VBLANK to poll the maple
bus. This patch makes the interrupt shareable.

By definition the interrupt is for both devices.
