Michael Ellerman de4c928b84 [POWERPC] Avoid DMA exception when using axon_msi with IOMMU ... There's a brown-paper-bag bug in axon_msi, we pass the address of our FIFO directly to the hardware, without DMA mapping it. This leads to DMA exceptions if you enable MSI & the IOMMU. The fix is to correctly DMA map the fifo, dma_alloc_coherent() does what we want - and we need to track the virt & phys addresses.
