A probe-time deadlock can occur between the dequeue worker and
drm_client_register(). During probe, drm_client_register() holds
clientlist_mutex and calls the fbdev hotplug callback, which triggers an
atomic commit that ends up sleeping in virtio_gpu_queue_ctrl_sgs()
waiting for virtqueue space. The dequeue worker that would free that
space calls virtio_gpu_cmd_get_display_info_cb(), which invokes
drm_kms_helper_hotplug_event() -> drm_client_dev_hotplug(), attempting
to acquire the same clientlist_mutex. Since wake_up() is only called
after the resp_cb loop, the probe thread is never woken and both threads
deadlock.
Fix this by removing the hotplug notification from
virtio_gpu_cmd_get_display_info_cb(). The display data (outputs[i].info)
is still updated synchronously in the callback.
For the init path, drm_client_register() already fires an initial
hotplug when the client is registered, which picks up the connector
state updated by display_info_cb.
For the runtime config_changed path, add a wait_event_timeout() in
config_changed_work_func() so that display_info_cb updates the connector
data before the hotplug notification is sent. Also replace
drm_helper_hpd_irq_event() with drm_kms_helper_hotplug_event() since
virtio-gpu never calls drm_kms_helper_poll_init() and thus
drm_helper_hpd_irq_event() always returns false without doing anything.

The cause is that the tvp5150 i2c module uses v4l2_async, but

In that corner case sd->asc_list is empty, so

Commit 53b7c271f0 ("smb: client: restrict implied bcc[0] exemption to

exception to responses without a data area. However, the overlap
handling in __smb2_calc_size() clears data_length, which can make an
invalid response appear to have no data area and so qualify for the
exception.
Track data area overlap separately and reject such responses before
applying the length compatibility exceptions.

Before this change, xfstests generic/496 was not supported on ksmbd:
generic/496 ... [not run] fallocated swap not supported here
ksmbd handles SetEOF as truncate, so EOF extension alone does not
allocate backing blocks. A fallocated swapfile can therefore still
look sparse to swapon.
Request allocation for EOF-extending fallocate ranges that can be
represented by FILE_ALLOCATION_INFORMATION, and refresh the allocation
state afterwards.
With this change, xfstests generic/496 and generic/701 pass on ksmbd.
However, Samba "strict allocate = no" now exposes the real generic/701
failure: the old pass came from inflated local i_blocks, not from
server allocation. generic/213 also fails in that case because an
oversized allocation request may not return ENOSPC.

When a mode 0 fallocate extends EOF from 1G to 2G + 1M, the client
currently sends SetEOF for 2G + 1M. This can make fallocate return
success without allocating the requested range, or allocate extra
space before that range.
For example, on a fresh file:
xfs_io -f \
-c "falloc 0 1G" \
-c "falloc 2G 1M" \
-c "truncate 3G" test
The second fallocate should allocate [2G, 2G + 1M), leaving [1G, 2G)
as a hole.
Before this change, the result depended on the server allocation policy.
With Samba "strict allocate = no", SetEOF could return success without
allocating [2G, 2G + 1M). With "strict allocate = yes":
# filefrag -v test
[0, 1G) allocated
[1G, 2G) allocated unexpectedly
[2G, 2G + 1M) allocated
SMB cannot allocate that arbitrary range, so write zeroes to small
EOF-extending ranges instead. Limit this to 1 MiB to bound the
client-side I/O cost.
With "strict allocate = no", the requested range [2G, 2G + 1M) is
allocated by the writes. With "strict allocate = yes":
# filefrag -v test
[0, 1G) allocated
[1G, 2G) hole
[2G, 2G + 1M) allocated
This fixes the small EOF-extending range case exercised by generic/213.

The fallocate emulation allocates a 1 MiB zero-filled buffer even
though each SMB2_write request is limited to SMB2_MAX_BUFFER_SIZE,
which is 64 KiB. A high-order 1 MiB allocation is more likely to
fail on a fragmented system.
Allocate only the smaller of the requested range and SMB2_MAX_BUFFER_SIZE,
and reuse that zero-filled buffer for every write request. Also reject
a successful write that makes no progress to avoid looping indefinitely.
This reduces the contiguous allocation required by fallocate emulation
without changing the written data or range semantics.

smb3_simple_fallocate_range() can skip holes when an allocated range
returned by the server starts before the current fallocate offset. The
skipped hole is not zero-filled, but fallocate still returns success. A
later write to that hole may therefore fail with ENOSPC.
The function queries allocated ranges so that it can preserve existing
contents and write zeroes only into holes. However, the server may return
a range that starts before the current fallocate offset.
For example, assume the fallocate request is [100, 400) and the only
allocated range returned by the server is [0, 200):
Request: [100, 400)
Server range: [ 0, 200) allocated
Correct:
[100, 200) allocated data, skip
[200, 400) hole, zero-fill
Current:
[100, 300) skipped
[300, 400) zero-filled afterwards
The current code adds the full server range length, 200, to the current
offset 100 and moves to 300. As a result, the hole in [200, 300) is
skipped without being zero-filled.
Fix this by advancing only over the part of the allocated range that
overlaps the current fallocate offset. Ignore ranges that end before the
current offset and reject ranges whose end offset overflows.
This also prevents a malformed range length from causing an out-of-bounds
zero-buffer read.

FSCTL_DUPLICATE_EXTENTS_TO_FILE changes the target file extents on the
server, but the client does not refresh the target AllocationSize/i_blocks.
Callers can observe or use the wrong st_blocks value immediately after the
clone, before a later attribute revalidation corrects it.
For example, create a reflinked file with a leading hole:
xfs_io -f -c "pwrite -S 0x61 0 64k" src
touch dst
chmod 600 dst
xfs_io -c "reflink src 0 1m 64k" dst
mkswap dst
swapon dst
The file still has a hole after mkswap:
/mnt/scratch/dst:
[0..7]: allocated
[8..2047]: hole
[2048..2175]: allocated
The server also reports only the allocated ranges:
server dst size=1114112 blocks=144
but the client reported EOF-derived blocks:
client dst size=1114112 blocks=2176
and swapon succeeded:
swapon_result=success
/mnt/scratch/dst 1.1M 0B -1
So EOF-derived i_blocks can let a sparse reflinked file pass the CIFS
swapfile hole check.
Fix this by querying FILE_ALL_INFORMATION on the target handle after a
successful duplicate extents request. Update i_blocks from AllocationSize
and keep the refreshed target inode attributes valid so a following stat
does not immediately revalidate again.
If the query fails, mark the cached inode attributes stale so a later
getattr can refresh them.
This also fixes the xfstests generic/370 regression introduced by the
i_blocks accounting change, as tested on a Samba "vfs objects = btrfs"
share.

setting is board-specific and should be handled by BIOS/firmware rather
than the generic codec driver, especially since inline remote support
is not currently implemented.

Fix the Ethernet PHY description on the DART-MX9 Sonata boards.
The GPIO previously described as the PHY reset line is actually a
board-level enable signal required by the PHY. Model it accordingly and
remove the incorrect reset GPIO description from the PHY nodes.
On i.MX91 and i.MX93 the signal is described as a fixed regulator,
whereas the existing regulator description on i.MX95 is reused.
Keeping the PHY enable asserted during boot ensures that Ethernet
initialization completes successfully.

More bug fixes, many found by tools:
- Protect from a possible DOS with certain RMPP traffic patterns
- Correct mac address comparison so CMA works properly on IB
- Some crashes in irdma around memory registration
- Uninitialized value in erdma and mana
- Wrong order setting up a QP in SIW allowed a network packet to reach an
unready QP struct
- Catch math overflows in hns and irdma

On most Qualcomm SoCs where minidump is supported, a word in always-on
SRAM is shared between the operating system (OS) and boot firmware.
Before DDR is initialized on the warm reset following a crash, firmware
reads this word to decide if minidump is enabled and collect a minidump,
and where to deliver it (USB upload to a host, or save to local
storage). The OS is expected to select one of the destinations.
The SRAM region is described by a 'sram' phandle on the SCM DT node.
If the property is absent the feature is silently disabled, keeping
existing SoCs unaffected.
Expose a 'minidump_dest' module parameter (default: usb) so the user
can select the destination. Only the string names "usb" or "storage"
are accepted.

__scm is published in qcom_scm_probe() with smp_store_release()
but qcom_scm_set_download_mode() reads it directly without
smp_load_acquire(), creating a potential ordering violation where a
CPU could observe a stale or partially initialised __scm pointer.
Use smp_load_acquire() to acquire __scm in the
qcom_scm_set_download_mode() function.

On Qualcomm SoCs that support minidump, a word in always-on SRAM
is shared between the Operating System(HLOS) and boot firmware.
OS is expected to select the minidump download destination
either USB upload to a host PC or save to on-device storage.
Boot firmware will reads this word before DDR is initialized
on the warm reset following a crash to decide where to deliver
the minidump.
Add a 'sram' property to the SCM binding to allow the OS to
identify this SRAM region via a phandle.

MGMT_EV_DEVICE_DISCONNECTED carries a reason field which is defined to
be one of MGMT_DEV_DISCONN_* (0x00..0x05). hci_disconn_complete_evt()
converts the HCI error with hci_to_mgmt_reason(), but two other paths
pass the raw HCI error straight through:
hci_cs_disconnect() -> cp->reason
mgmt_connect_failed() -> status
The latter is reached whenever the adapter is powered off or suspended:
hci_disconnect_all_sync() aborts every link with
HCI_ERROR_REMOTE_POWER_OFF, hci_disconnect_sync() deliberately does not
wait for HCI_EV_DISCONN_COMPLETE for that reason, so that
hci_abort_conn_sync() finishes the connection off through
hci_conn_failed() instead.
As a result userspace sees an out of range reason:
@ MGMT Event: Device Disconnected (0x000c) plen 8
BR/EDR Address: 8C:A9:6F:2C:51:46
Reason: Reserved (0x15)
bluetoothd: btd_bearer_disconnected() Unknown disconnection value: 21
bluetoothd: device_disconnected() Unknown disconnection value: 21
Export hci_to_mgmt_reason() and use it in both places, so that a power
off is reported as MGMT_DEV_DISCONN_REMOTE rather than as the raw
HCI_ERROR_REMOTE_POWER_OFF (0x15).
