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. The only file where some GFP_ flags are updated is 'pci.c'. When memory is allocated in '_rtl_pci_init_tx_ring()' and '_rtl_pci_init_rx_ring()' GFP_KERNEL can be used because both functions are called from a probe function and no spinlock is taken. The call chain is: rtl_pci_probe --> rtl_pci_init --> _rtl_pci_init_trx_ring --> _rtl_pci_init_rx_ring --> _rtl_pci_init_tx_ring @@ @@ - 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.jaillet@wanadoo.fr> --- If needed, see post from Christoph Hellwig on the kernel-janitors ML: https://marc.info/?l=kernel-janitors&m=158745678307186&w=4 V2: rebased on latest wireless-drivers-next because V1 does not apply cleanly anymore --- drivers/net/wireless/realtek/rtlwifi/pci.c | 116 +++++++++--------- .../wireless/realtek/rtlwifi/rtl8188ee/hw.c | 9 +- .../wireless/realtek/rtlwifi/rtl8188ee/trx.c | 13 +- .../wireless/realtek/rtlwifi/rtl8192ce/trx.c | 14 +-- .../wireless/realtek/rtlwifi/rtl8192de/trx.c | 12 +- .../wireless/realtek/rtlwifi/rtl8192ee/trx.c | 13 +- .../wireless/realtek/rtlwifi/rtl8192se/trx.c | 12 +- .../wireless/realtek/rtlwifi/rtl8723ae/trx.c | 14 +-- .../wireless/realtek/rtlwifi/rtl8723be/hw.c | 9 +- .../wireless/realtek/rtlwifi/rtl8723be/trx.c | 13 +- .../wireless/realtek/rtlwifi/rtl8821ae/hw.c | 9 +- .../wireless/realtek/rtlwifi/rtl8821ae/trx.c | 13 +- 12 files changed, 115 insertions(+), 132 deletions(-)
