The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'ql_alloc_net_req_rsp_queues()' GFP_KERNEL can be used because it is only called from 'ql_alloc_mem_resources()' which already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see below) When memory is allocated in 'ql_alloc_buffer_queues()' GFP_KERNEL can be used because this flag is already used just a few line above. When memory is allocated in 'ql_alloc_small_buffers()' GFP_KERNEL can be used because it is only called from 'ql_alloc_mem_resources()' which already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see above) When memory is allocated in 'ql_alloc_mem_resources()' GFP_KERNEL can be used because this function already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see above) While at it, use 'dma_set_mask_and_coherent()' instead of 'dma_set_mask()/ dma_set_coherent_mask()' in order to slightly simplify code. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3;
