/*
 * These are the virtual IRQ numbers, we divide all IRQ's into
 * 'spaces', the 'space' determines where and how to enable/disable
 * that particular IRQ on an SGI machine. HPC DMA and MC DMA interrupts
 * are not supported this way. Driver is supposed to allocate HPC/MC
 * interrupt as shareable and then look to proper status bit (see
 * HAL2 driver). This will prevent many complications, trust me ;-)
