In station/client mode, the link data needs a bit more
initialization and destruction than just zero-init and
kfree() respectively, implement that.
This required some shuffling of the link data handling
in general, as we should set it up in setup and do the
teardown in teardown, otherwise we're asymmetric in
case of interface type changes.
Also stop using kfree_rcu(), we cannot guarantee that
nothing is scheduling things that live within the link
(e.g. the u.mgd.request_smps_work) until we're sure it
cannot be referenced anymore, therefore synchronize
instead. This isn't very efficient, but we can always
optimize it later.

With the split into keys[]/deflink.gtk[] arrays, WEP keys are
still installed into the keys[] array, but we didn't look them
up there. This meant they weren't deleted correctly.
Fix this by looking up the key there even if it's not pairwise

For multi-link operation, this cannot work as the req->bss pointer

tracing for the MLO case here. Drop the BSS elements for now as
they're not the most useful thing, and it's hard to size things
correctly for the MLO case (without adding a lot of code that's
also executed when tracing isn't enabled.)

ieee80211s_update_metric function uses sta_set_rate_info_tx
function to get struct rate_info data from ieee80211_tx_rate
struct, present in ieee80211_sta->deflink.tx_stats. However,
drivers can skip tx rate calculation by setting rate idx as
-1. Such drivers provides rate_info directly and hence
ieee80211s metric is updated incorrectly since ieee80211_tx_rate
has inconsistent data.

In AP mode, multicast traffic is handled very differently from normal traffic,
especially if at least one client is in powersave mode.
This means that multicast packets can be buffered a lot longer than normal
unicast packets, and can eat up the AQL budget very quickly because of the low
data rate.
Along with the recent change to maintain a global PHY AQL limit, this can lead
to significant latency spikes for unicast traffic.
Since queueing multicast to hardware is currently not constrained by AQL limits
anyway, let's just exclude it from the AQL pending airtime calculation entirely.

Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
- quieten the spectre-bhb prints

- fix thumb unaligned access abort emulation
- fix amba_device_add() refcount underflow
- fix literal placement

The UML function names to_virt() and to_phys() are exposed by UML
headers, and are very generic and may be defined by drivers. As it
turns out, commit 9409c9b670 ("pmem: refactor pmem_clear_poison()")
did exactly that.
This results in build errors such as the following when trying to build
um:allmodconfig:
drivers/nvdimm/pmem.c: In function ‘pmem_dax_zero_page_range’:
./arch/um/include/asm/page.h:105:20: error: too few arguments to function ‘to_phys’
105 | #define __pa(virt) to_phys((void *) (unsigned long) (virt))
| ^~~~~~~
Use less generic function names for the um specific to_phys() and
to_virt() functions to fix the problem and to avoid similar problems in
the future.

Hopefully the last PR for 5.19. This became bigger than wished,
but all changes are pretty device-specific small fixes, which
look less worrisome.
The majority of changes are about various ASoC fixes, while the
usual HD-audio quirks are included as well.

nfp_tun_write_neigh() function will configure a tunnel neighbour when
calling nfp_tun_neigh_event_handler() or nfp_flower_cmsg_process_one_rx()
(with no tunnel neighbour type) from firmware.
When configuring IP on physical port as a tunnel endpoint, no operation
will be performed after receiving the cmsg mentioned above.
Therefore, add a progress to configure tunnel neighbour in this case.
v2: Correct format of fixes tag.
Fixes: f1df7956c1 ("nfp: flower: rework tunnel neighbour configuration")
