The wrappers in include/linux/pci-dma-compat.h should go away. 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 'fst_add_one()', GFP_KERNEL can be used because it is a probe function and no lock is acquired. @@ @@ - 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; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jail...@wanadoo.fr> --- If needed, see post from Christoph Hellwig on the kernel-janitors ML: https://marc.info/?l=kernel-janitors&m=158745678307186&w=4 --- drivers/net/wan/farsync.c | 25 ++++++++++++------------- 1 file changed, 12 insertions(+), 13 deletions(-) diff --git a/drivers/net/wan/farsync.c b/drivers/net/wan/farsync.c index 5ff249b76525..b50cf11d197d 100644 --- a/drivers/net/wan/farsync.c +++ b/drivers/net/wan/farsync.c @@ -2553,16 +2553,16 @@ fst_add_one(struct pci_dev *pdev, const struct pci_device_id *ent) * Allocate a dma buffer for transmit and receives */ card->rx_dma_handle_host = - pci_alloc_consistent(card->device, FST_MAX_MTU, - &card->rx_dma_handle_card); + dma_alloc_coherent(&card->device->dev, FST_MAX_MTU, + &card->rx_dma_handle_card, GFP_KERNEL); if (card->rx_dma_handle_host == NULL) { pr_err("Could not allocate rx dma buffer\n"); err = -ENOMEM; goto rx_dma_fail; } card->tx_dma_handle_host = - pci_alloc_consistent(card->device, FST_MAX_MTU, - &card->tx_dma_handle_card); + dma_alloc_coherent(&card->device->dev, FST_MAX_MTU, + &card->tx_dma_handle_card, GFP_KERNEL); if (card->tx_dma_handle_host == NULL) { pr_err("Could not allocate tx dma buffer\n"); err = -ENOMEM; @@ -2572,9 +2572,8 @@ fst_add_one(struct pci_dev *pdev, const struct pci_device_id *ent) return 0; /* Success */ tx_dma_fail: - pci_free_consistent(card->device, FST_MAX_MTU, - card->rx_dma_handle_host, - card->rx_dma_handle_card); + dma_free_coherent(&card->device->dev, FST_MAX_MTU, + card->rx_dma_handle_host, card->rx_dma_handle_card); rx_dma_fail: fst_disable_intr(card); for (i = 0 ; i < card->nports ; i++) @@ -2625,12 +2624,12 @@ fst_remove_one(struct pci_dev *pdev) /* * Free dma buffers */ - pci_free_consistent(card->device, FST_MAX_MTU, - card->rx_dma_handle_host, - card->rx_dma_handle_card); - pci_free_consistent(card->device, FST_MAX_MTU, - card->tx_dma_handle_host, - card->tx_dma_handle_card); + dma_free_coherent(&card->device->dev, FST_MAX_MTU, + card->rx_dma_handle_host, + card->rx_dma_handle_card); + dma_free_coherent(&card->device->dev, FST_MAX_MTU, + card->tx_dma_handle_host, + card->tx_dma_handle_card); } fst_card_array[card->card_no] = NULL; } -- 2.25.1
