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.

Vladimir Oltean says: ==================== DSA tag_8021q cleanup This small series tries to consolidate the VLAN handling in DSA a little bit. It reworks tag_8021q to be minimally invasive to the dsa_switch_ops structure. This makes the rest of the code a bit easier to follow. ==================== Signed-off-by: -

This reverts commit 314f76d7. Citing that commit message, the call graph was: dsa_slave_vlan_rx_add_vid dsa_port_setup_8021q_tagging | | | | | +-------------+ | | v v dsa_port_vid_add dsa_slave_port_obj_add | | +-------+ +-------+ | | v v dsa_port_vlan_add Now that tag_8021q has its own ops structure, it no longer relies on dsa_port_vid_add, and therefore on the dsa_switch_ops to install its VLANs. So dsa_port_vid_add now only has one single caller. So we can simplify the call graph to what it was before, aka: dsa_slave_vlan_rx_add_vid dsa_slave_port_obj_add | | +-------+ +-------+ | | v v dsa_port_vlan_add Signed-off-by:

While working on another tag_8021q driver implementation, some things became apparent: - It is not mandatory for a DSA driver to offload the tag_8021q VLANs by using the VLAN table per se. For example, it can add custom TCAM rules that simply encapsulate RX traffic, and redirect & decapsulate rules for TX traffic. For such a driver, it makes no sense to receive the tag_8021q configuration through the same callback as it receives the VLAN configuration from the bridge and the 8021q modules. - Currently, sja1105 (the only tag_8021q user) sets a priv->expect_dsa_8021q variable to distinguish between the bridge calling, and tag_8021q calling. That can be improved, to say the least. - The crosschip bridging operations are, in fact, stateful already. The list of crosschip_links must be kept by the caller and passed to the relevant tag_8021q functions. So it would be nice if the tag_8021q configuration was more self-contained. This patch attempts to do that. Create a struct dsa_8021q_context which encapsulates a struct dsa_switch, and has 2 function pointers for adding and deleting a VLAN. These will replace the previous channel to the driver, which was through the .port_vlan_add and .port_vlan_del callbacks of dsa_switch_ops. Also put the list of crosschip_links into this dsa_8021q_context. Drivers that don't support cross-chip bridging can simply omit to initialize this list, as long as they dont call any cross-chip function. The sja1105_vlan_add and sja1105_vlan_del functions are refactored into a smaller sja1105_vlan_add_one, which now has 2 entry points: - sja1105_vlan_add, from struct dsa_switch_ops - sja1105_dsa_8021q_vlan_add, from the tag_8021q ops But even this change is fairly trivial. It just reflects the fact that for sja1105, the VLANs from these 2 channels end up in the same hardware table. However that is not necessarily true in the general sense (and that's the reason for making this change). The rest of the patch is mostly plain refactoring of "ds" -> "ctx". The dsa_8021q_context structure needs to be propagated because adding a VLAN is now done through the ops function pointers inside of it. Signed-off-by:

There is no point in calling dsa_port_setup_8021q_tagging for each individual port. Additionally, it will become more difficult to do that when we'll have a context structure to tag_8021q (next patch). So refactor this now. Signed-off-by:

Remove the tx_queue->handle_tso function pointer, and just use tx_queue->tso_version to decide which function to call, thus removing an indirect call from the fast path. Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired tx_queue->tso_version before calling it. In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by setting tx_queue->tso_version to 0, which will cause the TX path to use the GSO-based fallback. Signed-off-by:

Each MDB entry is encoded in a nested netlink attribute called 'MDBA_MDB_ENTRY'. In turn, this attribute contains another nested attributed called 'MDBA_MDB_ENTRY_INFO', which encodes a single port group entry within the MDB entry. The cited commit added the ability to restart a dump from a specific port group entry. However, on failure to add a port group entry to the dump the entire MDB entry (stored in 'nest2') is removed, resulting in missing port group entries. Fix this by finalizing the MDB entry with the partial list of already encoded port group entries.
