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

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.

                           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
                      |                         |

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.

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.
