f4f92db439 virtio: features, fixes, cleanups
Several new features here:
 
 - Virtio find vqs API has been reworked
   (required to fix the scalability issue we have with
    adminq, which I hope to merge later in the cycle)
 
 - vDPA driver for Marvell OCTEON
 
 - virtio fs performance improvement
 
 - mlx5 migration speedups
 
 Fixes, cleanups all over the place.

b5d14b0c67 wifi: virt_wifi: avoid reporting connection success with wrong SSID
When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).

The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.

Fixed it by checking the SSID (from user space) in the connection code.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

There were are a number of cases in mac80211 and iwlwifi (at
least) that used the sband->iftype_data pointer directly,
instead of using the accessors to find the right array entry
to use.

Make sparse warn when such a thing is done.

                        __read_overflow2_field(q_size_field, size);

The compiler actually complains on 'mac80211_hwsim_get_et_strings()' where
fortification logic inteprets call to 'memcpy()' as an attempt to copy the
whole 'mac80211_hwsim_gstrings_stats' array from its first member and so
issues an overread warning. This warning may be silenced by passing
an address of the whole array and not the first member to 'memcpy()'.

556eb8b791 Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1.
 
 Once again, a busy development cycle, with lots of changes happening in
 the driver core in the quest to be able to move "struct bus" and "struct
 class" into read-only memory, a task now complete with these changes.
 
 This will make the future rust interactions with the driver core more
 "provably correct" as well as providing more obvious lifetime rules for
 all busses and classes in the kernel.
 
 The changes required for this did touch many individual classes and
 busses as many callbacks were changed to take const * parameters
 instead.  All of these changes have been submitted to the various
 subsystem maintainers, giving them plenty of time to review, and most of
 them actually did so.
 
 Other than those changes, included in here are a small set of other
 things:
   - kobject logging improvements
   - cacheinfo improvements and updates
   - obligatory fw_devlink updates and fixes
   - documentation updates
   - device property cleanups and const * changes
   - firwmare loader dependency fixes.
 
 All of these have been in linux-next for a while with no reported
 problems.
