qdisc_reset() is clearing qdisc->q.qlen and qdisc->qstats.backlog
_after_ calling qdisc->ops->reset. There is no need to clear them
again in the specific reset function.

Commit c70727a5bc18 ("xen: allow more than 512 GB of RAM for 64 bit
pv-domains") from July 2015 replaces the config XEN_MAX_DOMAIN_MEMORY with
a new config XEN_512GB, but misses to adjust arch/x86/configs/xen.config.
As XEN_512GB defaults to yes, there is no need to explicitly set any config
in xen.config.
Just remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY.

LoongArch only support 32-bit/64-bit xchg/cmpxchg in native. But percpu
operation, qspinlock and some drivers need 8-bit/16-bit xchg/cmpxchg. We
add subword xchg/cmpxchg emulation in this patch because the emulation
has better performance than the generic implementation (on NUMA system),
and it can fix some build errors meanwhile [1].
LoongArch's guarantee for forward progress (avoid many ll/sc happening
at the same time and no one succeeds):
We have the "exclusive access (with timeout) of ll" feature to avoid
simultaneous ll (which also blocks other memory load/store on the same
address), and the "random delay of sc" feature to avoid simultaneous
sc. It is a mandatory requirement for multi-core LoongArch processors
to implement such features, only except those single-core and dual-core
processors (they also don't support multi-chip interconnection).
Feature bits are introduced in CPUCFG3, bit 3 and bit 4 [2].

When enable GENERIC_IOREMAP, there will be circular dependency to cause

but pgtable.h need some macros defined in io.h. So cleanup those macros

commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT")
made the assumption that it was the only one handling tablets and thus
kept an internal state regarding the tool.
Turns out that the uclogic driver has a timer to release the in range
bit, effectively making hid-input ignoring all in range information
after the very first one.
Fix that by having a more rationale approach which consists in forwarding
every event and let the input stack filter out the duplicates.

There is a timing issue captured during ishtp client sending stress tests.
It was observed during stress tests that ISH firmware is getting out of
ordered messages. This is a rare scenario as the current set of ISH client
drivers don't send much data to firmware. But this may not be the case
going forward.
When message size is bigger than IPC MTU, ishtp splits the message into
fragments and uses serialized async method to send message fragments.
The call stack:
ishtp_cl_send_msg_ipc->ipc_tx_callback(first fregment)->
ishtp_send_msg(with callback)->write_ipc_to_queue->
write_ipc_from_queue->callback->ipc_tx_callback(next fregment)......
When an ipc write complete interrupt is received, driver also calls
write_ipc_from_queue->ipc_tx_callback in ISR to start sending of next fragment.
Through ipc_tx_callback uses spin_lock to protect message splitting, as the
serialized sending method will call back to ipc_tx_callback again, so it doesn't
put sending under spin_lock, it causes driver cannot guarantee all fragments
be sent in order.
Considering this scenario:
ipc_tx_callback just finished a fragment splitting, and not call ishtp_send_msg
yet, there is a write complete interrupt happens, then ISR->write_ipc_from_queue
->ipc_tx_callback->ishtp_send_msg->write_ipc_to_queue......
Because ISR has higher exec priority than normal thread, this causes the new
fragment be sent out before previous fragment. This disordered message causes
invalid message to firmware.
The solution is, to send fragments synchronously:
Use ishtp_write_message writing fragments into tx queue directly one by one,
instead of ishtp_send_msg only writing one fragment with completion callback.
As no completion callback be used, so change ipc_tx_callback to ipc_tx_send.

From 'IEEE Std 802.11-2020 section 11.8.8.4.1':
The mesh channel switch may be triggered by the need to avoid
interference to a detected radar signal, or to reassign mesh STA
channels to ensure the MBSS connectivity.
A 20/40 MHz MBSS may be changed to a 20 MHz MBSS and a 20 MHz
MBSS may be changed to a 20/40 MHz MBSS.
Since the standard allows the change of bandwidth during
the channel switch in mesh, remove the bandwidth check present in
ieee80211_set_csa_beacon.

In ieee80211_tx_dequeue() we currently allow a control port

For an AP interface, when userspace specifieds the link ID to
transmit the control port frame on (in particular for the
initial 4-way-HS), due to the logic in ieee80211_build_hdr()
for a frame transmitted from/to an MLD, we currently build a
header with
A1 = DA = MLD address of the peer MLD
A2 = local link address (!)
A3 = SA = local MLD address
This clearly makes no sense, and leads to two problems:
- if the frame were encrypted (not true for the initial
4-way-HS) the AAD would be calculated incorrectly
- if iTXQs are used, the frame is dropped by logic in
ieee80211_tx_dequeue()
Fix the addressing, which fixes the first bullet, and the
second bullet for peer MLDs, I'll fix the second one for
non-MLD peers separately.

The next patch will require splitting the data here into
AP and non-AP because for EHT, the format of the MCS/NSS
support (struct ieee80211_eht_mcs_nss_supp) is different,
for AP the only_20mhz cannot be used.

Draft P802.11be_D2.1, section 35.3.17 states that the EML Capabilities
Field shouldn't be included in case the device doesn't have support for
EMLSR or EMLMR.

When queuing frames to an interface store the link ID we
determined (which possibly came from the driver in the
RX status in the first place) in the RX status, and use
it in the MLME code to send probe responses, beacons and
CSA frames to the right link.

In MLO, when the address translation from link to MLD is done
in fw/hw, it is necessary to be able to have some information
on the link on which the frame has been received. Extend the
rx API to include link_id and a valid flag in ieee80211_rx_status.
Also make chanes to mac80211 rx APIs to make use of the reported
link_id after sanity checks.

Add support for various key operations on MLD by adding new parameter
link_id. Pass the link_id received from userspace to driver for add_key,
get_key, del_key, set_default_key, set_default_mgmt_key and
set_default_beacon_key to support configuring keys specific to each MLO
link. Userspace must not specify link ID for MLO pairwise key since it
is common for all the MLO links.

Currently, MLO support is not added for WEXT code and WEXT handlers are
prevented on MLDs. Prevent WEXT handler cfg80211_wext_siwencodeext()
also on MLD which is missed in commit 7b0a0e3c3a88 ("wifi: cfg80211: do
some rework towards MLO link APIs")

We've already freed the assoc_data at this point, so need
to use another copy of the AP (MLD) address instead.

The Tx queue parameters are per link, so add the link ID
from nl80211 parameters to the API.
While at it, lock the wdev when calling into the driver
so it (and we) can check the link ID appropriately.
