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 'mpi_map_card()' GFP_KERNEL can be used because this function is called from a probe or a module_init() function and no spinlock is taken in the between. The call chains are: airo_init_module module_init function in 'airo.c' or airo_probe .probe function in 'airo_cs.c' --> airo_config followed in both cases by: --> init_airo_card --> _init_airo_card --> mpi_map_card @@ @@ - 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> Signed-off-by:

Grygorii Strashko says: ==================== net: ethernet: ti: ale: add static configuration As existing, as newly introduced CPSW ALE versions have differences in supported features and ALE table formats. Especially it's actual for the recent AM65x/J721E/J7200 and future AM64x SoCs, which supports more features like: auto-aging, classifiers, Link aggregation, additional HW filtering, etc. The existing ALE configuration interface is not practical in terms of adding new features and requires consumers to program a lot static parameters. And any attempt to add new features will case endless adding and maintaining different combination of flags and options. Because CPSW ALE configuration is static and fixed for SoC (or set of SoC), It is reasonable to add support for static ALE configurations inside ALE module. This series introduces static ALE configuration table for different ALE variants and provides option for consumers to select required ALE configuration by providing ALE const char *dev_id identifier (Patch 2). And all existing driver have been switched to use new approach (Patches 3-6). After this ALE HW auto-ageing feature can be enabled for AM65x CPSW ALE variant (Patch 7). Finally, Patches 8-9 introduces tables to describe the ALE VLAN entries fields as the ALE VLAN entries are too much differ between different TI CPSW ALE versions. So, handling them using flags, defines and get/set functions are became over-complicated. Patch 1 - is preparation patch Changes in v3: - fixed comment for Patch 2 Changes in v2: - fixed sparse warnings v2: https://lore.kernel.org/patchwork/cover/1301684/ v1: https://lore.kernel.org/patchwork/cover/1301048/ ==================== Signed-off-by:

The AM65x ALE supports HW auto-ageing which can be enabled by programming ageing interval in ALE_AGING_TIMER register. For this CPSW fck_clk frequency has to be know by ALE.
