[Why]
DWB (Display Writeback) flag needs to be enabled as 1, or system
will throw out a few warnings when creating dcn20 resource pool.
Also, Navi14's dwb setting needs to match Navi10's,
which has already been set to 1.
[How]
Change value of num_dwb from 0 to 1.

The API was reduced to include only knowledge currently needed by the
FW scan logic, the rest is legacy. Support the new, reduced version.
Using the old API with newer firmwares (starting from
iwlwifi-*-50.ucode, which implements and requires the new API version)
causes an assertion failure similar to this one:

mt76 dma layer is supposed to unmap skb data buffers while keep txwi
mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does
not unmap data fragments in even positions for non-linear skbs. This
issue may result in hw hangs with A-MSDU if the system relies on IOMMU
or SWIOTLB. Fix this behaviour properly unmapping data fragments on
non-linear skbs.

On same device (e.g. U7612E-H1) PCIE_ASPM causes continuous mcu hangs and
instability. Since mt76x2 series does not manage PCIE PS states, first we
try to disable ASPM using pci_disable_link_state. If it fails, we will
disable PCIE PS configuring PCI registers.

This cures a panic on restart after a kexec operation on 5.3 and 5.4

The underlying state of the iommu registers (iommu->flags &
VTD_FLAG_TRANS_PRE_ENABLED) on a restart results in a domain being marked as
"DEFER_DEVICE_DOMAIN_INFO" that produces an Oops in identity_mapping().

pn532 devices support an autopoll command, that lets the chip
automatically poll for selected nfc technologies instead of manually
looping through every single nfc technology the user is interested in.
This is faster and less cpu and bus intensive than manually polling.
This adds this autopoll capability to the pn533 driver.

There is a problem in the initialisation and setup of the pn533: It
registers with nfc too early. It could happen, that it finished
registering with nfc and someone starts using it. But setup of the pn533
is not yet finished. Bad or at least unintended things could happen.
So I split out nfc registering (and unregistering) to seperate functions
that have to be called late in probe then.
i2c requires a bit more love: i2c requests an irq in it's probe
function. 'Commit 32ecc75ded72 ("NFC: pn533: change order operations in
dev registation")' shows, this can not happen too early. An irq can be
served before structs are fully initialized. The way chosen to prevent
this is to request the irq after nfc_alloc_device initialized the
structs, but before nfc_register_device. So there is now this
pn532_i2c_nfc_alloc function.

This adds hooks for dev_up and dev_down to the phy_ops. They are
optional.
The idea is to inform the phy driver when the nfc chip is really going
to be used. When it is not used, the phy driver can suspend it's
interface to the nfc chip to save some power. The nfc chip is considered
not in use before dev_up and after dev_down.

It is favourable to have one unified compatible string for devices that

This patch is meant to address possible race conditions that can exist
between network configuration and power management. A similar issue was
fixed for igb in commit 9474933caf21 ("igb: close/suspend race in
netif_device_detach").
In addition it consolidates the code so that the PCI error handling code
will essentially perform the power management freeze on the device prior to
attempting a reset, and will thaw the device afterwards if that is what it
is planning to do. Otherwise when we call close on the interface it should
see it is detached and not attempt to call the logic to down the interface
and free the IRQs again.
From what I can tell the check that was adding the check for __E1000_DOWN
in e1000e_close was added when runtime power management was added. However
it should not be relevant for us as we perform a call to
pm_runtime_get_sync before we call e1000_down/free_irq so it should always
be back up before we call into this anyway.

When a bonding interface is being created, it setups its mode and options.
At that moment, it uses mode_lock so mode_lock should be initialized
before that moment.
rtnl_newlink()
rtnl_create_link()
alloc_netdev_mqs()
->setup() //bond_setup()
->newlink //bond_newlink
bond_changelink()
register_netdevice()
->ndo_init() //bond_init()
After commit 089bca2caed0 ("bonding: use dynamic lockdep key instead of
subclass"), mode_lock is initialized in bond_init().
So in the bond_changelink(), un-initialized mode_lock can be used.
mode_lock should be initialized in bond_setup().
This patch partially reverts commit 089bca2caed0 ("bonding: use dynamic
lockdep key instead of subclass")
Test command:
ip link add bond0 type bond mode 802.3ad lacp_rate 0

it takes a lot of cycles to clean up the used buffer,

Prior to this patch, the amount of counters guaranteed per VF in the
resource tracker was MLX4_VF_COUNTERS_PER_PORT * MLX4_MAX_PORTS. It was
set regardless if the VF was single or dual port.
This caused several VFs to have no guaranteed counters although the
system could satisfy their request.
The fix is to dynamically guarantee counters, based on each VF
specification.

Ethtool self test contains a test for link speed. This test reads the
PTYS register and determines whether the current speed is valid or not.
Change current implementation to use the function mlx5e_port_linkspeed()
that does the same check and fails when speed is invalid. This code
redundancy lead to a bug when mlx5e_port_linkspeed() was updated with
expended speeds and the self test was not.

When CQE compression is enabled, compressed CQEs use the following
structure: a title is followed by one or many blocks, each containing 8
mini CQEs (except the last, which may contain fewer mini CQEs).
Due to NAPI budget restriction, a complete structure is not always
parsed in one NAPI run, and some blocks with mini CQEs may be deferred
to the next NAPI poll call - we have the mlx5e_decompress_cqes_cont call
in the beginning of mlx5e_poll_rx_cq. However, if the budget is
extremely low, some blocks may be left even after that, but the code
that follows the mlx5e_decompress_cqes_cont call doesn't check it and
assumes that a new CQE begins, which may not be the case. In such cases,
random memory corruptions occur.
An extremely low NAPI budget of 8 is used when busy_poll or busy_read is
active.
This commit adds a check to make sure that the previous compressed CQE
has been completely parsed after mlx5e_decompress_cqes_cont, otherwise
it prevents a new CQE from being fetched in the middle of a compressed
CQE.
This commit fixes random crashes in __build_skb, __page_pool_put_page
and other not-related-directly places, that used to happen when both CQE
compression and busy_poll/busy_read were enabled.

Geneve implementation changed mlx5 tc to user direct pointer to tunnel_key
action's internal struct ip_tunnel_info instance. However, this leads to
use-after-free error when initial filter that caused creation of new encap
entry is deleted or when tunnel_key action is manually overwritten through
action API. Moreover, with recent TC offloads API unlocking change struct
flow_action_entry->tunnel point to temporal copy of tunnel info that is
deallocated after filter is offloaded to hardware which causes bug to
reproduce every time new filter is attached to existing encap entry with
following KASAN bug:

Fix the issue by duplicating tunnel info into per-encap copy that is
deallocated with encap structure. Also, duplicate tunnel info in flow parse
attribute to support cases when flow might be attached asynchronously.
