Currently, duplicated rules are rejected only for skip_hw or "none",
hence allowing users to push duplicates into HW for no reason.
Use the flower tables to protect for that.

The CP rings are accounted differently on the new 57500 chips. There
must be enough CP rings for the sum of RX and TX rings on the new
chips. The current logic may be over-estimating the RX and TX rings.
The output parameter max_cp should be the maximum NQs capped by
MSIX vectors available for networking in the context of 57500 chips.
The existing code which uses CMPL rings capped by the MSIX vectors
works most of the time but is not always correct.

The new 57500 chips have introduced the NQ structure in addition to
the existing CP rings in all chips. We need to introduce a new
bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the
same and one will just call the other. On the new chips, they
refer to the 2 separate ring structures. The new function is now
called to determine the resource (NQ or CP rings) associated with
MSIX that are in use.
On 57500 chips, the RDMA driver does not use the CP rings so
we don't need to do the subtraction adjustment.

The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use
1 CP ring per MSIX vector. To better unify this, add a resv_irqs
field to struct bnxt_hw_resc. On legacy chips, we initialize resv_irqs
with resv_cp_rings. On new chips, we initialize it with the allocated
MSIX resources.

Recent changes to support the 57500 devices have created this
regression. The bnxt_hwrm_queue_qportcfg() call was moved to be
called earlier before the RDMA support was determined, causing
the CoS queues configuration to be set before knowing whether RDMA
was supported or not. Fix it by moving it to the right place right
after RDMA support is determined.

The Marvell 6390 Ethernet switch family does not perform MDIO
turnaround correctly. Many hardware MDIO bus masters don't care about
this, but the bitbangging implementation in Linux does by default. Add
phy_ignore_ta_mask to the platform data so that the bitbangging code
can be told which devices are known to get TA wrong.

It is sometimes necessary to instantiate a bit-banging MDIO bus as a
platform device, without the aid of device tree.
When device tree is being used, the bus is not scanned for devices,
only those devices which are in device tree are probed. Without device
tree, by default, all addresses on the bus are scanned. This may then
find a device which is not a PHY, e.g. a switch. And the switch may
have registers containing values which look like a PHY. So during the
scan, a PHY device is wrongly created.
After the bus has been registered, a search is made for
mdio_board_info structures which indicates devices on the bus, and the
driver which should be used for them. This is typically used to
instantiate Ethernet switches from platform drivers. However, if the
scanning of the bus has created a PHY device at the same location as
indicated into the board info for a switch, the switch device is not
created, since the address is already busy.
This can be avoided by setting the phy_mask of the mdio bus. This mask
prevents addresses on the bus being scanned.

extra_uref is used in __ip(6)_append_data only if uarg is set.
Smatch sees that the variable is passed to sock_zerocopy_put_abort.
This function accesses it only when uarg is set, but smatch cannot
infer this.
Make this dependency explicit.

alloc_hugepage_direct_gfpmask"
This reverts commit 89c83fb539f95491be80cdd5158e6f0ce329e317.
This should have been done as part of 2f0799a0ffc0 ("mm, thp: restore
node-local hugepage allocations"). The movement of the thp allocation
policy from alloc_pages_vma() to alloc_hugepage_direct_gfpmask() was
intended to only set __GFP_THISNODE for mempolicies that are not
MPOL_BIND whereas the revert could set this regardless of mempolicy.
While the check for MPOL_BIND between alloc_hugepage_direct_gfpmask()
and alloc_pages_vma() was racy, that has since been removed since the
revert. What is left is the possibility to use __GFP_THISNODE in
policy_node() when it is unexpected because the special handling for
hugepages in alloc_pages_vma() was removed as part of the consolidation.
Secondly, prior to 89c83fb539f9, alloc_pages_vma() implemented a somewhat
different policy for hugepage allocations, which were allocated through
alloc_hugepage_vma(). For hugepage allocations, if the allocating
process's node is in the set of allowed nodes, allocate with
__GFP_THISNODE for that node (for MPOL_PREFERRED, use that node with
__GFP_THISNODE instead). This was changed for shmem_alloc_hugepage() to
allow fallback to other nodes in 89c83fb539f9 as it did for new_page() in
mm/mempolicy.c which is functionally different behavior and removes the
requirement to only allocate hugepages locally.
So this commit does a full revert of 89c83fb539f9 instead of the partial
revert that was done in 2f0799a0ffc0. The result is the same thp
allocation policy for 4.20 that was in 4.19.
Fixes: 89c83fb539f9 ("mm, thp: consolidate THP gfp handling into alloc_hugepage_direct_gfpmask")
Fixes: 2f0799a0ffc0 ("mm, thp: restore node-local hugepage allocations")

This reverts commit 624ca9c33c8a853a4a589836e310d776620f4ab9.
This commit is completely bogus. The STACR register has two formats, old
and new, depending on the version of the IP block used. There's a pair of
device-tree properties that can be used to specify the format used:
has-inverted-stacr-oc
has-new-stacr-staopc
What this commit did was to change the bit definition used with the old
parts to match the new parts. This of course breaks the driver on all
the old ones.
Instead, the author should have set the appropriate properties in the
device-tree for the variant used on his board.
