Add some basic documentation (zh_CN version) for LoongArch. LoongArch is
a new RISC ISA, which is a bit like MIPS or RISC-V. LoongArch includes a
reduced 32-bit version (LA32R), a standard 32-bit version (LA32S) and a
64-bit version (LA64).

HTVEC will be shared by both MIPS-based and LoongArch-based Loongson
processors (not only Loongson-3), so we adjust its description. HTPIC is
only used by MIPS-based Loongson, so we add a MIPS dependency.

The header cleanup series from Masahiro Yamada ended up causing

This was only caught after the original patches got merged, but
at least the fixes are trivial and hopefully complete.

Commit cfc1d27789 ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.
This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.
So, set the prefix back to "module.".

net: af_packet: be careful when expanding mac header size
A recent regression in af_packet needed a preliminary debug patch,
which will presumably be useful for next bugs hunting.
The af_packet fix is to make sure MAC headers are contained in
skb linear part, as GSO stack requests.
v2: CONFIG_DEBUG_NET depends on CONFIG_NET to avoid compile
errors found by kernel bots.

While analyzing yet another syzbot report, I found the following
patch very useful. It allows to better understand what went wrong.
This debug info is only enabled if CONFIG_DEBUG_NET=y,
which is the case for syzbot builds.

I have a board where these two lines are always printed during boot:
imx-dwmac 30bf0000.ethernet: Cannot register the MDIO bus
imx-dwmac 30bf0000.ethernet: stmmac_dvr_probe: MDIO bus (id: 1) registration failed
It's perfectly fine, and the device is successfully (and silently, as
far as the console goes) probed later.
Use dev_err_probe() instead, which will demote these messages to debug
level (thus removing the alarming messages from the console) when the
error is -EPROBE_DEFER, and also has the advantage of including the
error code if/when it happens to be something other than -EPROBE_DEFER.
While here, add the missing \n to one of the format strings.

The {pid,uid}_t fields of struct binder_transaction were recently
replaced to use kernel types in commit 169adc2b6b ("android/binder.h:
add linux/android/binder(fs).h to UAPI compile-test coverage").
However, using __kernel_uid_t here breaks backwards compatibility in
architectures using 16-bits for this type, since glibc and some others
still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which
avoids this compatibility problem.

Global `-Warray-bounds` enablement revealed some problems, one of
which is the way we define and use AQC rules messages.
In fact, they have a shared header, followed by the actual message,
which can be of one of several different formats. So it is
straightforward enough to define that header as a separate struct
and then embed it into message structures as needed, but currently
all the formats reside in one union coupled with the header. Then,
the code allocates only the memory needed for a particular message
format, leaving the union potentially incomplete.
There are no actual reads or writes beyond the end of an allocated
chunk, but at the same time, the whole implementation is fragile and
backed by an equilibrium rather than strong type and memory checks.
Define the structures the other way around: one for the common
header and the rest for the actual formats with the header embedded.
There are no places where several union members would be used at the
same time anyway. This allows to use proper struct_size() and let
the compiler know what is going to be done.
Finally, unsilence `-Warray-bounds` back for ice_switch.c.
Other little things worth mentioning:
* &ice_sw_rule_vsi_list_query is not used anywhere, remove it. It's
weird anyway to talk to hardware with purely kernel types
(bitmaps);
* expand the ICE_SW_RULE_*_SIZE() macros to pass a structure
variable name to struct_size() to let it do strict typechecking;
* rename ice_sw_rule_lkup_rx_tx::hdr to ::hdr_data to keep ::hdr
for the header structure to have the same name for it constistenly
everywhere;
* drop the duplicate of %ICE_SW_RULE_RX_TX_NO_HDR_SIZE residing in
ice_switch.h.

NFDK firmware supports 48-bit dma addressing and
parses 16 high bits of dma addresses.
In nfp_nfdk_tx_desc, dma related structure and tso
related structure are union. When "mss" be filled
with nonzero value due to enable tso, the memory used
by "padding" may be also filled. Then, firmware may
parse wrong dma addresses which causes TX watchdog
timeout problem.
This patch removes padding and unifies the dma_addr_hi
bits with the one in firmware. nfp_nfdk_tx_desc_set_dma_addr
is also added to match this change.

There are session cleanup problems in ax25_release() and
ax25_disconnect(). If we setup a session and then disconnect,
the disconnected session is still in "LISTENING" state that
is shown below.
Active AX.25 sockets
Dest Source Device State Vr/Vs Send-Q Recv-Q
DL9SAU-4 DL9SAU-3 ??? LISTENING 000/000 0 0
DL9SAU-3 DL9SAU-4 ??? LISTENING 000/000 0 0
The first reason is caused by del_timer_sync() in ax25_release().
The timers of ax25 are used for correct session cleanup. If we use
ax25_release() to close ax25 sessions and ax25_dev is not null,
the del_timer_sync() functions in ax25_release() will execute.
As a result, the sessions could not be cleaned up correctly,
because the timers have stopped.
In order to solve this problem, this patch adds a device_up flag
in ax25_dev in order to judge whether the device is up. If there
are sessions to be cleaned up, the del_timer_sync() in
ax25_release() will not execute. What's more, we add ax25_cb_del()
in ax25_kill_by_device(), because the timers have been stopped
and there are no functions that could delete ax25_cb if we do not
call ax25_release(). Finally, we reorder the position of
ax25_list_lock in ax25_cb_del() in order to synchronize among
different functions that call ax25_cb_del().
The second reason is caused by improper check in ax25_disconnect().
The incoming ax25 sessions which ax25->sk is null will close
heartbeat timer, because the check "if(!ax25->sk || ..)" is
satisfied. As a result, the session could not be cleaned up properly.
In order to solve this problem, this patch changes the improper
check to "if(ax25->sk && ..)" in ax25_disconnect().
What`s more, the ax25_disconnect() may be called twice, which is
not necessary. For example, ax25_kill_by_device() calls
ax25_disconnect() and sets ax25->state to AX25_STATE_0, but
ax25_release() calls ax25_disconnect() again.
In order to solve this problem, this patch add a check in
ax25_release(). If the flag of ax25->sk equals to SOCK_DEAD,
the ax25_disconnect() in ax25_release() should not be executed.

A rare BUG_ON triggered in assoc_array_gc:
[3430308.818153] kernel BUG at lib/assoc_array.c:1609!
Which corresponded to the statement currently at line 1593 upstream:
BUG_ON(assoc_array_ptr_is_meta(p));
Using the data from the core dump, I was able to generate a userspace
reproducer[1] and determine the cause of the bug.
[1]: https://github.com/brenns10/kernel_stuff/tree/master/assoc_array_gc
After running the iterator on the entire branch, an internal tree node
looked like the following:
NODE (nr_leaves_on_branch: 3)
SLOT [0] NODE (2 leaves)
SLOT [1] NODE (1 leaf)
SLOT [2..f] NODE (empty)
In the userspace reproducer, the pr_devel output when compressing this
node was:
-- compress node 0x5607cc089380 --
free=0, leaves=0
[0] retain node 2/1 [nx 0]
[1] fold node 1/1 [nx 0]
[2] fold node 0/1 [nx 2]
[3] fold node 0/2 [nx 2]
[4] fold node 0/3 [nx 2]
[5] fold node 0/4 [nx 2]
[6] fold node 0/5 [nx 2]
[7] fold node 0/6 [nx 2]
[8] fold node 0/7 [nx 2]
[9] fold node 0/8 [nx 2]
[10] fold node 0/9 [nx 2]
[11] fold node 0/10 [nx 2]
[12] fold node 0/11 [nx 2]
[13] fold node 0/12 [nx 2]
[14] fold node 0/13 [nx 2]
[15] fold node 0/14 [nx 2]
after: 3
At slot 0, an internal node with 2 leaves could not be folded into the
node, because there was only one available slot (slot 0). Thus, the
internal node was retained. At slot 1, the node had one leaf, and was
able to be folded in successfully. The remaining nodes had no leaves,
and so were removed. By the end of the compression stage, there were 14
free slots, and only 3 leaf nodes. The tree was ascended and then its
parent node was compressed. When this node was seen, it could not be
folded, due to the internal node it contained.
The invariant for compression in this function is: whenever
nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT, the node should contain all
leaf nodes. The compression step currently cannot guarantee this, given
the corner case shown above.
To fix this issue, retry compression whenever we have retained a node,
and yet nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT. This second
compression will then allow the node in slot 1 to be folded in,
satisfying the invariant. Below is the output of the reproducer once the
fix is applied:
-- compress node 0x560e9c562380 --
free=0, leaves=0
[0] retain node 2/1 [nx 0]
[1] fold node 1/1 [nx 0]
[2] fold node 0/1 [nx 2]
[3] fold node 0/2 [nx 2]
[4] fold node 0/3 [nx 2]
[5] fold node 0/4 [nx 2]
[6] fold node 0/5 [nx 2]

[13] fold node 0/12 [nx 2]
[14] fold node 0/13 [nx 2]
[15] fold node 0/14 [nx 2]
internal nodes remain despite enough space, retrying
-- compress node 0x560e9c562380 --
free=14, leaves=1
[0] fold node 2/15 [nx 0]

tx_channel_offset is calculated in efx_allocate_msix_channels, but it is
also calculated again in efx_set_channels because it was originally done
there, and when efx_allocate_msix_channels was introduced it was
forgotten to be removed from efx_set_channels.
Moreover, the old calculation is wrong when using
efx_separate_tx_channels because now we can have XDP channels after the
TX channels, so n_channels - n_tx_channels doesn't point to the first TX
channel.
Remove the old calculation from efx_set_channels, and add the
initialization of this variable if MSI or legacy interrupts are used,
next to the initialization of the rest of the related variables, where
it was missing.
This has been already done for sfc, do it also for sfc_siena.

Normally, all channels have RX and TX queues, but this is not true if
modparam efx_separate_tx_channels=1 is used. In that cases, some
channels only have RX queues and others only TX queues (or more
preciselly, they have them allocated, but not initialized).
Fix efx_channel_has_tx_queues to return the correct value for this case
too.

Commit 4bd69ecfa6 ("dt-bindings: i3c: Convert cdns,i3c-master to DT
schema") and commit 6742ca620b ("dt-bindings: i3c: Convert
snps,dw-i3c-master to DT schema") convert some i3c dt-bindings to yaml,
but miss to adjust its reference in MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about
broken references.
Repair these file references in I3C DRIVER FOR CADENCE I3C MASTER IP and
I3C DRIVER FOR SYNOPSYS DESIGNWARE.

Pull more erofs updates from Gao Xiang:
"This is a follow-up to the main updates, including some fixes of
fscache mode related to compressed inodes and a cachefiles tracepoint.
There is also a patch to fix an unexpected decompression strategy
change due to a cleanup in the past. All the fixes are quite small.
Apart from these, documentation is also updated for a better
description of recent new features.
In addition, this has some trivial cleanups without actual code logic
changes, so I could have a more recent codebase to work on folios and
avoiding the PG_error page flag for the next cycle.
Summary:
- Leave compressed inodes unsupported in fscache mode for now
- Avoid crash when using tracepoint cachefiles_prep_read
- Fix `backmost' behavior due to a recent cleanup
- Update documentation for better description of recent new features
- Several decompression cleanups w/o logical change"
