Some third-party controllers, such as the HORPIAD FPS for Nintendo Switch
and Gamesir-G3w, require a specific packet that the first-party XInput
driver sends before it will start sending reports. It's not currently known
what this packet does, but since the first-party driver always sends it's
unlikely that this could cause issues with existing controllers.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends

struct mux_adth actually ends with multiple struct mux_adth_dg members.
This is seen both in the comments about the member:
/**
* struct mux_adth - Structure of the Aggregated Datagram Table Header.
...
* @dg: datagramm table with variable length
*/
and in the preparation for populating it:
adth_dg_size = offsetof(struct mux_adth, dg) +
ul_adb->dg_count[i] * sizeof(*dg);
...
adth_dg_size -= offsetof(struct mux_adth, dg);
memcpy(&adth->dg, ul_adb->dg[i], adth_dg_size);
This was reported as a run-time false positive warning:
memcpy: detected field-spanning write (size 16) of single field "&adth->dg" at drivers/net/wwan/iosm/iosm_ipc_mux_codec.c:852 (size 8)
Adjust the struct mux_adth definition and associated sizeof() math; no binary
output differences are observed in the resulting object file.

Pull regmap fix from Mark Brown:
"One more fix for v6.4
The earlier fix to take account of the register data size when
limiting raw register writes exposed the fact that the Intel AVMM bus
was incorrectly specifying too low a limit on the maximum data
transfer, it is only capable of transmitting one register so had set a
transfer size limit that couldn't fit both the value and the the
register address into a single message"

This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13.
This change appears to have broken things...
We now see applications hanging during disk accesses.
e.g.
multi-port virtio-blk device running in h/w (FPGA)
Host running a simple 'fio' test.
[global]
thread=1
direct=1
ioengine=libaio
norandommap=1
group_reporting=1
bs=4K
rw=read
iodepth=128
runtime=1
numjobs=4
time_based
[job0]
filename=/dev/vda
[job1]
filename=/dev/vdb
[job2]
filename=/dev/vdc
...
[job15]
filename=/dev/vdp
i.e. 16 disks; 4 queues per disk; simple burst of 4KB reads
This is repeatedly run in a loop.
After a few, normally <10 seconds, fio hangs.
With 64 queues (16 disks), failure occurs within a few seconds; with 8 queues (2 disks) it may take ~hour before hanging.
Last message:
fio-3.19
Starting 8 threads
Jobs: 1 (f=1): [_(7),R(1)][68.3%][eta 03h:11m:06s]
I think this means at the end of the run 1 queue was left incomplete.
'diskstats' (run while fio is hung) shows no outstanding transactions.
e.g.
$ cat /proc/diskstats
...
252 0 vda 1843140071 0 14745120568 712568645 0 0 0 0 0 3117947 712568645 0 0 0 0 0 0
252 16 vdb 1816291511 0 14530332088 704905623 0 0 0 0 0 3117711 704905623 0 0 0 0 0 0
...
Other stats (in the h/w, and added to the virtio-blk driver ([a]virtio_queue_rq(), [b]virtblk_handle_req(), [c]virtblk_request_done()) all agree, and show every request had a completion, and that virtblk_request_done() never gets called.
e.g.
PF= 0 vq=0 1 2 3
[a]request_count - 839416590 813148916 105586179 84988123
[b]completion1_count - 839416590 813148916 105586179 84988123
[c]completion2_count - 0 0 0 0
PF= 1 vq=0 1 2 3
[a]request_count - 823335887 812516140 104582672 75856549
[b]completion1_count - 823335887 812516140 104582672 75856549
[c]completion2_count - 0 0 0 0
i.e. the issue is after the virtio-blk driver.
This change was introduced in kernel 6.3.0.
I am seeing this using 6.3.3.
If I run with an earlier kernel (5.15), it does not occur.
If I make a simple patch to the 6.3.3 virtio-blk driver, to skip the blk_mq_add_to_batch()call, it does not fail.
e.g.
kernel 5.15 - this is OK
virtio_blk.c,virtblk_done() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
blk_mq_complete_request(req);
}
kernel 6.3.3 - this fails
virtio_blk.c,virtblk_handle_req() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
if (!blk_mq_complete_request_remote(req)) {
if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) {
virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed
}
}
}
If I do, kernel 6.3.3 - this is OK
virtio_blk.c,virtblk_handle_req() [irq handler]
if (likely(!blk_should_fake_timeout(req->q))) {
if (!blk_mq_complete_request_remote(req)) {
virtblk_request_done(req); //force this here...
if (!blk_mq_add_to_batch(req, iob, virtblk_vbr_status(vbr), virtblk_complete_batch)) {
virtblk_request_done(req); //this never gets called... so blk_mq_add_to_batch() must always succeed
}
}
}
Perhaps you might like to fix/test/revert this change...

This reverts commit da9ef50f545f86ffe6ff786174d26500c4db737a.
This fixes a regression in which the link would come up, but no
communication was possible.
The reverted commit was also removing a comment about
DP83867_PHYCR_FORCE_LINK_GOOD, this is not added back in this commits
since it seems that this is unrelated to the original code change.
