More late-caught fallout from the mainline merge. The patch: [POWERPC] Use archdata.dma_data in dma_direct_ops and add the offset "Now that all platforms using dma_direct_offset setup the archdata.dma_data correctly, ..." Nope -- the pasemi iommu setup code that disables translation on the DMA pci device didn't set dma_data correctly. The below patch is needed, please merge as soon as practical. Thanks!Sorry about that. I'm confused though, didn't your device come from alloc_pci_dev() which kzalloc()s the pci_dev which contains the archdata which contains the dma_data, ie. dma_data will already be 0?
Yeah, I don't see how my patch could work (but it did), since the code falls through and overwrites dma_data with the pointer to the table, just as before. Weird, I did test it last night. See new patch. -Olof
