After ptep_clear_flush(), if we find that src_folio is pinned we will fail
UFFDIO_MOVE and put src_folio back to src_pte entry, but the change to
src_folio->{mapping,index} is not restored in this process. This is not
what we expected, so fix it.
This can cause the rmap for that page to be invalid, possibly resulting
in memory corruption. At least swapout+migration would no longer work,
because we might fail to locate the mappings of that folio.

allocations
Sven reports an infinite loop in __alloc_pages_slowpath() for costly order
__GFP_RETRY_MAYFAIL allocations that are also GFP_NOIO. Such combination
can happen in a suspend/resume context where a GFP_KERNEL allocation can
have __GFP_IO masked out via gfp_allowed_mask.
Quoting Sven:
1. try to do a "costly" allocation (order > PAGE_ALLOC_COSTLY_ORDER)
with __GFP_RETRY_MAYFAIL set.
2. page alloc's __alloc_pages_slowpath tries to get a page from the
freelist. This fails because there is nothing free of that costly
order.
3. page alloc tries to reclaim by calling __alloc_pages_direct_reclaim,
which bails out because a zone is ready to be compacted; it pretends
to have made a single page of progress.
4. page alloc tries to compact, but this always bails out early because
__GFP_IO is not set (it's not passed by the snd allocator, and even
if it were, we are suspending so the __GFP_IO flag would be cleared
anyway).
5. page alloc believes reclaim progress was made (because of the
pretense in item 3) and so it checks whether it should retry
compaction. The compaction retry logic thinks it should try again,
because:
a) reclaim is needed because of the early bail-out in item 4
b) a zonelist is suitable for compaction
6. goto 2. indefinite stall.
(end quote)
The immediate root cause is confusing the COMPACT_SKIPPED returned from
__alloc_pages_direct_compact() (step 4) due to lack of __GFP_IO to be
indicating a lack of order-0 pages, and in step 5 evaluating that in
should_compact_retry() as a reason to retry, before incrementing and
limiting the number of retries. There are however other places that
wrongly assume that compaction can happen while we lack __GFP_IO.
To fix this, introduce gfp_compaction_allowed() to abstract the __GFP_IO
evaluation and switch the open-coded test in try_to_compact_pages() to use
it.
Also use the new helper in:
- compaction_ready(), which will make reclaim not bail out in step 3, so
there's at least one attempt to actually reclaim, even if chances are
small for a costly order
- in_reclaim_compaction() which will make should_continue_reclaim()
return false and we don't over-reclaim unnecessarily
- in __alloc_pages_slowpath() to set a local variable can_compact,
which is then used to avoid retrying reclaim/compaction for costly
allocations (step 5) if we can't compact and also to skip the early
compaction attempt that we do in some cases

The current measured frame rate is 59.95Hz, which does not meet the
requirements of touch-stylus and stylus cannot work normally. After
adjustment, the actual measurement is 60.001Hz. Now this panel looks
like it's only used by me on the MTK platform, so let's change this

The linear ranges aren't really matching what they should be. Indeed,
the range is inclusive of the min value, so it makes sense the previous
range does NOT include the max step value representing the min value of
the range in question.
Since 3.4V is represented by the decimal value 232, the previous range
max step value should be 231 and not 232.
No expected change in behavior since 3.4V was mapped with step 232 from
the first range but is now mapped with step 232 from the second range.
While at it, remove the incorrect comment from the second range.

The linear ranges aren't really matching what they should be. Indeed,
the range is inclusive of the min value, so it makes sense the previous
range does NOT include the max step value representing the min value of
the range in question.
Since 1.5V is represented by the decimal value 160, the previous range
max step value should be 159 and not 160. Similarly, 3.4V is represented
by the decimal value 236, so the previous range max value should be 235
and not 237.
The only change in behavior this makes is that this actually modeled
the ranges to map step with decimal value 237 with 3.65V instead of
3.4V (the max supported by the HW).

selftests: mptcp: fixes for diag.sh
Here are two patches fixing issues in MPTCP diag.sh kselftest:
- Patch 1 makes sure the exit code is '1' in case of error, and not the
test ID, not to return an exit code that would be wrongly interpreted
by the ksefltests framework, e.g. '4' means 'skip'.
- Patch 2 avoids waiting for unnecessary conditions, which can cause
timeouts in some very slow environments.

When creating a lot of listener sockets, it is enough to wait only for
the last one, like we are doing before in diag.sh for other subtests.
If we do a check for each listener sockets, each time listing all
available sockets, it can take a very long time in very slow
environments, at the point we can reach some timeout.
When using the debug kconfig, the waiting time switches from more than
8 sec to 0.1 sec on my side. In slow/busy environments, and with a poll
timeout set to 30 ms, the waiting time could go up to ~100 sec because
the listener socket would timeout and stop, while the script would still
be checking one by one if all sockets are ready. The result is that
after having waited for everything to be ready, all sockets have been
stopped due to a timeout, and it is too late for the script to check how
many there were.
While at it, also removed ss options we don't need: we only need the
filtering options, to count how many listener sockets have been created.
We don't need to ask ss to display internal TCP information, and the
memory if the output is dropped by the 'wc -l' command anyway.

The test counter 'test_cnt' should not be returned in diag.sh, e.g. what
if only the 4th test fail? Will do 'exit 4' which is 'exit ${KSFT_SKIP}',
the whole test will be marked as skipped instead of 'failed'!
So we should do ret=${KSFT_FAIL} instead.

If drm_kms_helper_poll=n the output poll work will only get scheduled
from drm_helper_probe_single_connector_modes() to handle a delayed
hotplug event. Since polling is disabled the work in this case should
just call drm_kms_helper_hotplug_event() w/o detecting the state of
connectors and rescheduling the work.
After commit d33a54e3991d after a delayed hotplug event above the
connectors did get re-detected in the poll work and the work got
re-scheduled periodically (since poll_running is also false if
drm_kms_helper_poll=n), in effect ignoring the drm_kms_helper_poll=n
kernel param.
Fix the above by calling only drm_kms_helper_hotplug_event() for a
delayed hotplug event if drm_kms_helper_hotplug_event=n, as was done
before d33a54e3991d.

pskb_inet_may_pull() makes sure the needed headers are in skb->head.

I'm updating __assign_str() and will be removing the second parameter. To
make sure that it does not break anything, I make sure that it matches the
__string() field, as that is where the string is actually going to be
saved in. To make sure there's nothing that breaks, I added a WARN_ON() to
make sure that what was used in __string() is the same that is used in
__assign_str().
In doing this change, an error was triggered as __assign_str() now expects
the string passed in to be a char * value. I instead had the following
warning:
include/trace/events/qdisc.h: In function ‘trace_event_raw_event_qdisc_reset’:
include/trace/events/qdisc.h:91:35: error: passing argument 1 of 'strcmp' from incompatible pointer type [-Werror=incompatible-pointer-types]
91 | __assign_str(dev, qdisc_dev(q));
That's because the qdisc_enqueue() and qdisc_reset() pass in qdisc_dev(q)
to __assign_str() and to __string(). But that function returns a pointer
to struct net_device and not a string.
It appears that these events are just saving the pointer as a string and
then reading it as a string as well.
Use qdisc_dev(q)->name to save the device instead.

suspend/resume
When not configured for wakeup lis3lv02d_i2c_suspend() will call
lis3lv02d_poweroff() even if the device has already been turned off
by the runtime-suspend handler and if configured for wakeup and
the device is runtime-suspended at this point then it is not turned
back on to serve as a wakeup source.
Before commit b1b9f7a49440 ("misc: lis3lv02d_i2c: Add missing setting
of the reg_ctrl callback"), lis3lv02d_poweroff() failed to disable
the regulators which as a side effect made calling poweroff() twice ok.
Now that poweroff() correctly disables the regulators, doing this twice
triggers a WARN() in the regulator core:
unbalanced disables for regulator-dummy
WARNING: CPU: 1 PID: 92 at drivers/regulator/core.c:2999 _regulator_disable
...
Fix lis3lv02d_i2c_suspend() to not call poweroff() a second time if
already runtime-suspended and add a poweron() call when necessary to
make wakeup work.
lis3lv02d_i2c_resume() has similar issues, with an added weirness that
it always powers on the device if it is runtime suspended, after which
the first runtime-resume will call poweron() again, causing the enabled
count for the regulator to increase by 1 every suspend/resume. These
unbalanced regulator_enable() calls cause the regulator to never
be turned off and trigger the following WARN() on driver unbind:
WARNING: CPU: 1 PID: 1724 at drivers/regulator/core.c:2396 _regulator_put
Fix this by making lis3lv02d_i2c_resume() mirror the new suspend().

"A workaround to suppress the continuous bus resets in the case that
older devices are connected to the modern 1394 OHCI hardware and
devices
In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
However, it is well-known that the solution is not necessarily
effective in the mixing environment that both IEEE 1394-1995 PHY and
IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
of IEEE 1394a-2000.
The current implementation of firewire stack schedules the short bus
reset when attempting to resolve the mismatch of gap count in the
certain generation of bus topology. It can cause the continuous bus
reset in the issued environment.
The workaround simply uses the long bus reset instead of the short bus
reset. It is desirable to detect whether the issued environment or
not. However, the way to access PHY registers from remote note is
firstly defined in IEEE 1394a-2000, thus it is not available in the
case"

We accidently met the issue that the bash prompt is not shown after the
previous command done and until the next input if there's only one CPU
(In our issue other CPUs are isolated by isolcpus=). Further analysis
shows it's because the port entering runtime suspend even if there's
still pending chars in the buffer and the pending chars will only be
processed in next device resuming. We are using amba-pl011 and the
problematic flow is like below:
Bash kworker
tty_write()
file_tty_write()
n_tty_write()
uart_write()
__uart_start()
pm_runtime_get() // wakeup waker
queue_work()
pm_runtime_work()
rpm_resume()
status = RPM_RESUMING
serial_port_runtime_resume()
port->ops->start_tx()
pl011_tx_chars()
uart_write_wakeup()
[…]
__uart_start()
pm_runtime_get() < 0 // because runtime status = RPM_RESUMING
// later data are not commit to the port driver
status = RPM_ACTIVE
rpm_idle() -> rpm_suspend()
This patch tries to fix this by checking the port busy before entering
runtime suspending. A runtime_suspend callback is added for the port
driver. When entering runtime suspend the callback is invoked, if there's
still pending chars in the buffer then flush the buffer.

When userspace opens the console, we call set_termios() passing a
termios with the console's configured baud rate. Currently this causes
dw8250_set_termios() to disable and then re-enable the UART clock at
the same frequency as it was originally. This can cause corruption
of any concurrent console output. Fix it by skipping the reclocking
if we are already at the correct rate.

When about to transmit the function imx_uart_start_tx is called and in
some RS485 configurations this function will call imx_uart_stop_rx. The
problem is that imx_uart_stop_rx will enable loopback in order to
release the RS485 bus, but when loopback is enabled transmitted data
will just be looped to RX.
This patch fixes the above problem by not enabling loopback when about
to transmit.
This driver now works well when used for RS485 half duplex master
configurations.

The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values
in the ATA ID information to calculate cylinder and head values when
creating a CDB for READ or WRITE commands. The calculation involves
division and modulus operations, which will cause a crash if either of
these values is 0. While this never happens with a genuine device, it
could happen with a flawed or subversive emulation, as reported by the
syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if
either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID
information is 0. This requires isd200_Initialization() to return a
negative error code when initialization fails; currently it always
returns 0 (even when there is an error).

In commit 19416123ab3e ("block: define 'struct bvec_iter' as packed"),
what we need is to save the 4byte padding, and avoid `bio` to spread on
one extra cache line.
It is enough to define it as '__packed __aligned(4)', as '__packed'
alone means byte aligned, and can cause compiler to generate horrible
code on architectures that don't support unaligned access in case that
bvec_iter is embedded in other structures.

timestamping NAPI poll context
The NAPI poll context is a softirq context. Do not use normal spinlock API
in this context to prevent concurrency issues.

occurs after populating the metadata_map
Just simply reordering the functions mlx5e_ptp_metadata_map_put and
mlx5e_ptpsq_track_metadata in the mlx5e_txwqe_complete context is not good
enough since both the compiler and CPU are free to reorder these two
functions. If reordering does occur, the issue that was supposedly fixed by
7e3f3ba97e6c ("net/mlx5e: Track xmit submission to PTP WQ after populating
metadata map") will be seen. This will lead to NULL pointer dereferences in
mlx5e_ptpsq_mark_ts_cqes_undelivered in the NAPI polling context due to the
tracking list being populated before the metadata map.
