Add a driver for the Marvell 88Q2220. This driver allows to detect the
link, switch between 100BASE-T1 and 1000BASE-T1 and switch between
master and slave mode. Autonegotiation is supported.

====================
tls: fixes for record type handling with PEEK
There are multiple bugs in tls_sw_recvmsg's handling of record types
when MSG_PEEK flag is used, which can lead to incorrectly merging two
records:
- consecutive non-DATA records shouldn't be merged, even if they're
the same type (partly handled by the test at the end of the main
loop)
- records of the same type (even DATA) shouldn't be merged if one
record of a different type comes in between

If we queue 3 records:

- record 2, some other type

the current code can look past the 2nd record and merge the 2 data

If we queue 3 records:
- record 1, type DATA
- record 2, some other type
- record 3, type DATA
and do a recv(PEEK), the rx_list will contain the first two records.
The next large recv will walk through the rx_list and copy data from
record 1, then stop because record 2 is a different type. Since we
haven't filled up our buffer, we will process the next available
record. It's also DATA, so we can merge it with the current read.
We shouldn't do that, since there was a record in between that we
ignored.
Add a flag to let process_rx_list inform tls_sw_recvmsg that it had
more data available.

If we have a non-DATA record on the rx_list and another record of the
same type still on the queue, we will end up merging them:
- process_rx_list copies the non-DATA record
- we start the loop and process the first available record since it's
of the same type
- we break out of the loop since the record was not DATA
Just check the record type and jump to the end in case process_rx_list
did some work.

PEEK needs to leave decrypted records on the rx_list so that we can
receive them later on, so it jumps back into the async code that
queues the skb. Unfortunately that makes us skip the
TLS_RECORD_TYPE_DATA check at the bottom of the main loop, so if two
records of the same (non-DATA) type are queued, we end up merging
them.
Add the same record type check, and make it unlikely to not penalize
the async fastpath. Async decrypt only applies to data record, so this
check is only needed for PEEK.
process_rx_list also has similar issues.

Back in 2018 the commit be95a845cc44 ("bpf: avoid false sharing of map refcount
with max_entries") added ____cacheline_aligned to "struct bpf_map" to make sure
that fields like refcnt don't share a cache line with max_entries that is used
to bounds check map access. That was done to make spectre style attacks harder.
The main mitigation is done via code similar to array_index_nospec(), of course.
This was an additional precaution.
It increased the size of "struct bpf_map" a little, but it's affect on all
other maps (like array) is significant, since "struct bpf_map" is typically
the first member in other map types.
Undo this ____cacheline_aligned tag. Instead move freeze_mutex field around, so
that refcnt and max_entries are still in different cache lines.
The main effect is seen in sizeof(struct bpf_array) that reduces from 320
to 248 bytes.
BEFORE:
struct bpf_map {
const struct bpf_map_ops * ops; /* 0 8 */
...
char name[16]; /* 96 16 */
/* XXX 16 bytes hole, try to pack */
/* --- cacheline 2 boundary (128 bytes) --- */
atomic64_t refcnt __attribute__((__aligned__(64))); /* 128 8 */
...
/* size: 256, cachelines: 4, members: 30 */
/* sum members: 232, holes: 1, sum holes: 16 */
/* padding: 8 */
/* paddings: 1, sum paddings: 2 */
} __attribute__((__aligned__(64)));
struct bpf_array {
struct bpf_map map; /* 0 256 */
...
/* size: 320, cachelines: 5, members: 5 */
/* padding: 48 */
/* paddings: 1, sum paddings: 8 */
} __attribute__((__aligned__(64)));
AFTER:

/* size: 232, cachelines: 4, members: 30 */

commit 7418ec5b151f ("docs: translations: add translations links when they

TypeError: LanguagesNode.__init__() missing 1 required positional argument: 'current_language'
The full traceback has been saved in /tmp/sphinx-err-7xmwytuu.log, if you want to report the issue to the developers.
Solve this problem by making 'current_language' a true element attribute
of the LanguagesNode element, which is probably the more correct way to do
it anyway.

The GIC/ITS code is designed to ensure to pick up any preallocated LPI
tables on the redistributors, as enabling LPIs is a one-way switch. There
is no such restriction for vLPIs, and for GICv4.1 it is expected to
allocate a new vPE table at boot.
This works as intended when initializing an ITS, however when setting up a
redistributor in cpu_init_lpis() the early return for preallocated RD
tables skips straight past the GICv4 setup. This all comes to a head when
trying to kexec() into a new kernel, as the new kernel silently fails to
set up GICv4, leading to a complete loss of SGIs and LPIs for KVM VMs.
Slap a band-aid on the problem by ensuring its_cpu_init_lpis() always
initializes GICv4 on the way out, even if the other RD tables were
preallocated.

This reverts commit fcf690b0b47494df51d214db5c5a714a400b0257.
When using a wilc1000 chip over a spi bus, users can optionally define a
reset gpio and a chip enable gpio. The reset line of wilc1000 is active
low, so to hold the chip in reset, a low (physical) value must be applied.
The corresponding device tree binding documentation was introduced by
commit f31ee3c0a555 ("wilc1000: Document enable-gpios and reset-gpios
properties") and correctly indicates that the reset line is an active-low
signal. The corresponding driver part, brought by commit ec031ac4792c
("wilc1000: Add reset/enable GPIO support to SPI driver") was applying the
correct logic. But commit fcf690b0b474 ("wifi: wilc1000: use correct
sequence of RESET for chip Power-UP/Down") eventually flipped this logic
and started misusing the gpiod APIs, applying an inverted logic when
powering up/down the chip (for example, setting the reset line to a logic
"1" during power up, which in fact asserts the reset line when device tree
describes the reset line as GPIO_ACTIVE_LOW). As a consequence, any
platform currently using the driver in SPI mode must use a faulty reset
line description in device tree, or else chip will be maintained in reset
and will not even allow to bring up the chip.
Fix reset line usage by inverting back the gpiod APIs usage, setting the
reset line to the logic value "0" when powering the chip, and the logic
value "1" when powering off the chip.

The ACEPC W5 Pro HDMI stick contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
"brcmfmac43455-sdio.$(DEFAULT_STRING)-$(DEFAULT_STRING).txt" as nvram file
which is both too generic and messy with the $ symbols in the name.
The ACEPC W5 Pro uses the same Ampak AP6255 module as the ACEPC T8
and the nvram for the T8 is already in linux-firmware, so point the new
DMI nvram filename quirk to the T8 nvram file.

rtl8192cu is checking rtl_mac.tids when deciding if it should enable
aggregation. This is wrong because rtl_mac.tids is not initialised
anywhere. Check rtl_sta_info.tids instead, which is initialised.
Also, when enabling aggregation also enable RTS. The vendor driver does
this, my router does this. It seems like the thing to do.
Also also, it seems right to set the AMPDU density only when enabling
aggregation.
Also also also, delete the unused member rtl_mac.tids and the unused
macros RTL_AGG_ON and RTL_AGG_OFF.
Naturally, with working AMPDU the download/upload speeds are better.

The driver currently raises the following sparse warning:
[...] cfg80211.c:360:42: warning: incorrect type in assignment (different
base types)
[...] cfg80211.c:360:42: expected unsigned int key_mgmt_suite
[...] cfg80211.c:360:42: got restricted __be32 [usertype]
CHECK drivers/net/wireless/microchip/wilc1000/netdev.c
This conversion was needed because historically the external supplicant
(observed with wpa_supplicant) expects AKM suite as big endian in
NL80211_CMD_EXTERNAL_AUTH message when the AKM suite is WLAN_AKM_SUITE_SAE.
This is not needed anymore:
- new (to be released) versions of wpa_supplicant now reads it in host
endian _while_ keeping compatibility for older drivers
- for new drivers used with current/old wpa_supplicant, this conversion has
been added to nl80211 to force big endian when the AKM suite is
WLAN_AKM_SUITE_SAE
Remove this not-needed-anymore conversion to fix the sparse warning.

In [1] it was observed that the ath12k maintainers were not added to
the review of a new ath12k YAML file. Bartosz suggested "adding an N:
ath12k entry to MAINTAINERS" to prevent this in the future. In the
process it was noticed that one of the ath11k YAML files was also not
explicitly referenced, so add N: entries to ath10k, ath11k, and
ath12k, and remove the explicit F: entries.

ata_dev_power_is_active() and return if the device is already in

bus_get_dev_root() returns sp->dev_root which is set in subsys_register(),
but subsys_register() is not called by platform_bus_init().
Therefor for the platform_bus_type, bus_get_dev_root() always returns NULL.
This makes mbigen_of_create_domain() always return -ENODEV.
Don't try to retrieve the parent via bus_get_dev_root() and
unconditionally hand a NULL pointer to of_platform_device_create() to
fix this.

The CSA offset parsing happens the same way for all of
beacon template offsets, probe response template offsets
and TX offsets (for using during probe response TX from
userspace directly).
Refactor the parsing here. There's an additional check
this introduces, which is that the number of counters in
TX offsets doesn't exceed the driver capability, but as
only two counters are used at most for anything, this is
hopefully OK.

NL80211_CMD_EXTERNAL_AUTH
User-space supplicant (observed at least on wpa_supplicant) historically
parses the NL80211_ATTR_AKM_SUITES from the NL80211_CMD_EXTERNAL_AUTH
message as big endian _only_ when its value is WLAN_AKM_SUITE_SAE, while
processing anything else in host endian. This behavior makes any driver
relying on SAE external auth to switch AKM suite to big endian if it is
WLAN_AKM_SUITE_SAE. A fix bringing compatibility with both endianness
has been brought into wpa_supplicant, however we must keep compatibility
with older versions, while trying to reduce the occurences of this manual
conversion in wireless drivers.
Add the be32 conversion specifically on WLAN_AKM_SUITE_SAE in nl80211 layer
to keep compatibility with older wpa_supplicant versions.
