The patch titled Subject: nouveau: don't call pci_dma_supported has been removed from the -mm tree. Its filename was nouveau-dont-call-pci_dma_supported.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Christoph Hellwig <hch@xxxxxx> Subject: nouveau: don't call pci_dma_supported Just try to set a 64-bit DMA mask first and retry with the smaller dma_mask if dma_set_mask failed.
