arch/ppc or arch/powerpc?
If the latter, you need to translate the hardware IRQ into a virtual
IRQ. The easiest way to do this is to put the DMA node into the device
tree and use of_irq_to_resource().
Plus, this obviously isn't the exact code you're running, as the
spelling and capitalization errors would keep it from compiling.
