All these patches have already been posted. They have been generated with a coccinelle script. The tricky parts are patches that use dma_alloc_coherent() because the correct GFP flag has to be used in place of the previous embedded GFP_ATOMIC. Patches 1-3 are already Reviewed. References to the corresponding mail is given below the --- Patch 1-2,4-10 are just generated from the coccinelle script. Only too long lines have been hand modified. dma_alloc_coherent() modification are NOT part of these patches. Patch 3 also includes some 'dma_set_mask_and_coherent()' instead of 'pci_set_dma_mask()/pci_set_consistent_dma_mask()'. I've left this additional modification because it was reviewed with it. Patch 10-15 are the tricky parts. Explanation of which GFP flag is the right one is given in each patch. It has been divided in several patches to ease review. Patch 15 is the only one I'm slighly unsure with. The old code was using a GFP_USER flag in the function. I'm not familiar with it. I *guess* that GFP_KERNEL is fine, but maybe it should also be GFP_USER or left as GFP_ATOMIC so that nothing is changed. Patch 16 is the last step that remove "pci-dma-compat.h" and its only usage. All patches, exept 1-2,6 that are architecture specific, have been compile tested. After all that, a few rst files, 1 or 2 strings in error messages and some error branching labels should still need some attention. This is some minor issues. Only the cover letter is sent to every one. Each patch is sent to the corresponding maintainer(s) + Andrew Morton, Christoph Hellwig and Arnd Bergmann. Best regards.
