Performing a dummy read ensures that the register write operation is fully
completed, mitigating any potential bus delays that could otherwise impact
the frequency of bitbang usage. E.g., if the JTAG application uses GPIO to
control the JTAG pins (TCK, TMS, TDI, TDO, and TRST), and the application
sets the TCK clock to 1 MHz, the GPIO's high/low transitions will rely on
a delay function to ensure the clock frequency does not exceed 1 MHz.
However, this can lead to rapid toggling of the GPIO because the write
operation is POSTed and does not wait for a bus acknowledgment.

The `nouveau_dmem_copy_one` function ensures that the copy push command is
sent to the device firmware but does not track whether it was executed
successfully.
In the case of a copy error (e.g., firmware or hardware failure), the
copy push command will be sent via the firmware channel, and
`nouveau_dmem_copy_one` will likely report success, leading to the
`migrate_to_ram` function returning a dirty HIGH_USER page to the user.
This can result in a security vulnerability, as a HIGH_USER page that may
contain sensitive or corrupted data could be returned to the user.
To prevent this vulnerability, we allocate a zero page. Thus, in case of
an error, a non-dirty (zero) page will be returned to the user.

net: dsa: b53: assorted jumbo frame fixes
While investigating the capabilities of BCM63XX's integrated switch and
its DMA engine, I noticed a few issues in b53's jumbo frame code.
Mostly a confusion of MTU vs frame length, but also a few missing cases
for 100M switches.
Tested on BCM63XX and BCM53115 with intel 1G and realtek 1G NICs,
which support MTUs of 9000 or slightly above, but significantly less
than the 9716/9720 supported by BCM53115, so I couldn't verify the
actual maximum frame length.

All modern chips support and need the 10_100 bit set for supporting jumbo
frames on 10/100 ports, so instead of enabling it only for 583XX enable
it for everything except bcm63xx, where the bit is writeable, but does
nothing.
Tested on BCM53115, where jumbo frames were dropped at 10/100 speeds
without the bit set.

JMS_MAX_SIZE is the ethernet frame length, not the MTU, which is payload
without ethernet headers.
According to the datasheets maximum supported frame length for most
gigabyte swithes is 9720 bytes, so convert that to the expected MTU when
using VLAN tagged frames.

JMS_MIN_SIZE is the full ethernet frame length, while mtu is just the
data payload size. Comparing these two meant that mtus between 1500 and
1518 did not trigger enabling jumbo frames.
So instead compare the set mtu ETH_DATA_LEN, which is equal to
JMS_MIN_SIZE - ETH_HLEN - ETH_FCS_LEN;
Also do a check that the requested mtu is actually greater than the
minimum length, else we do not need to enable jumbo frames.
In practice this only introduced a very small range of mtus that did not
work properly. Newer chips allow 2000 byte large frames by default, and
older chips allow 1536 bytes long, which is equivalent to an mtu of
1514. So effectivly only mtus of 1515~1517 were broken.

Commit c938ab4da0eb ("net: phy: Manual remove LEDs to ensure correct

removing the LED entry from the LEDs list.
This cause kernel panic on specific scenario where the port for the PHY
is torn down and up and the kmod for the PHY is removed.
On setting the port down the first time, the assosiacted LEDs are
correctly unregistered. The associated kmod for the PHY is now removed.
The kmod is now added again and the port is now put up, the associated LED
are registered again.
On putting the port down again for the second time after these step, the
LED list now have 4 elements. With the first 2 already unregistered
previously and the 2 new one registered again.
This cause a kernel panic as the first 2 element should have been
removed.
Fix this by correctly removing the element when LED is unregistered.

Accessing device registers seems to be not reliable, the chip
revision is sometimes detected wrongly (0 instead of expected 1).
Ensure that the chip reset is performed via reset GPIO and then
wait for 'Device Ready' status in HW_CFG register before doing
any register initializations.

We have recently noticed the exact same KASAN splat as in commit
6cd4a78d962b ("net: do not leave a dangling sk pointer, when socket
creation fails"). The problem is that commit did not fully address the
problem, as some pf->create implementations do not use sk_common_release
in their error paths.
For example, we can use the same reproducer as in the above commit, but
changing ping to arping. arping uses AF_PACKET socket and if packet_create
fails, it will just sk_free the allocated sk object.
While we could chase all the pf->create implementations and make sure they
NULL the freed sk object on error from the socket, we can't guarantee
future protocols will not make the same mistake.
So it is easier to just explicitly NULL the sk pointer upon return from
pf->create in __sock_create. We do know that pf->create always releases the
allocated sk object on error, so if the pointer is not NULL, it is
definitely dangling.

When adding a delayed ref head, at delayed-ref.c:add_delayed_ref_head(),
if we fail to insert the qgroup record we don't error out, we ignore it.
In fact we treat it as if there was no error and there was already an
existing record - we don't distinguish between the cases where
btrfs_qgroup_trace_extent_nolock() returns 1, meaning a record already
existed and we can free the given record, and the case where it returns
a negative error value, meaning the insertion into the xarray that is
used to track records failed.
Effectively we end up ignoring that we are lacking qgroup record in the
dirty extents xarray, resulting in incorrect qgroup accounting.
Fix this by checking for errors and return them to the callers.

There are reports that system cannot suspend due to running trim because
the task responsible for trimming the device isn't able to finish in
time, especially since we have a free extent discarding phase, which can
trim a lot of unallocated space. There are no limits on the trim size
(unlike the block group part).
Since trime isn't a critical call it can be interrupted at any time,
in such cases we stop the trim, report the amount of discarded bytes and
return an error.

Per Qu Wenruo in case we have a very large disk, e.g. 8TiB device,
mostly empty although we will do the split according to our super block
locations, the last super block ends at 256G, we can submit a huge
discard for the range [256G, 8T), causing a large delay.
Split the space left to discard based on BTRFS_MAX_DISCARD_CHUNK_SIZE in
preparation of introduction of cancellation points to trim. The value
of the chunk size is arbitrary, it can be higher or derived from actual
device capabilities but we can't easily read that using
bio_discard_limit().

scx_qmap and other schedulers in the SCX repo are using SCX_ENQ_WAKEUP to
tell whether ops.select_cpu() was called. This is incorrect as
ops.select_cpu() can be skipped in the wakeup path and leads to e.g.
incorrectly skipping direct dispatch for tasks that are bound to a single
CPU.
sched core has been updated to specify ENQUEUE_RQ_SELECTED if
->select_task_rq() was called. Map it to SCX_ENQ_CPU_SELECTED and update
scx_qmap to test it instead of SCX_ENQ_WAKEUP.

was called
During ttwu, ->select_task_rq() can be skipped if only one CPU is allowed or
migration is disabled. sched_ext schedulers may perform operations such as
direct dispatch from ->select_task_rq() path and it is useful for them to
know whether ->select_task_rq() was skipped in the ->enqueue_task() path.
Currently, sched_ext schedulers are using ENQUEUE_WAKEUP for this purpose
and end up assuming incorrectly that ->select_task_rq() was called for tasks
that are bound to a single CPU or migration disabled.
Make select_task_rq() indicate whether ->select_task_rq() was called by
setting WF_RQ_SELECTED in *wake_flags and make ttwu_do_activate() map that
to ENQUEUE_RQ_SELECTED for ->enqueue_task().
This will be used by sched_ext to fix ->select_task_rq() skip detection.

value
This will be used to allow select_task_rq() to indicate whether
->select_task_rq() was called by modifying *wake_flags.
This makes try_to_wake_up() call all functions that take wake_flags with
WF_TTWU set. Previously, only select_task_rq() was. Using the same flags is
more consistent, and, as the flag is only tested by ->select_task_rq()
implementations, it doesn't cause any behavior differences.

interrupt-map number
The driver(drivers/irqchip/irq-ls-extirq.c) have not use standard DT
function to parser interrupt-map. So it doesn't consider '#address-size'
in parent interrupt controller, such as GIC.
When dt-binding verify interrupt-map, item data matrix is spitted at
incorrect position. So cause below warning:
arch/arm64/boot/dts/freescale/fsl-ls1088a-qds.dtb: interrupt-controller@14:
interrupt-map: [[0, 0, 1, 0, 0, 4, 1, 0], [1, 0, 1, 4, 2, 0, 1, 0], ...
is too short
Remove interrupt-map restriction to workaround this warning for
'fsl,ls1088a-extirq', 'fsl,ls2080a-extirq' and fsl,lx2160a-extirq.
Other keep the same restriction.

Since, two suspend-resume cycles are required to enter hibernate and,
since we only need to enable idle optimizations in the first cycle
(which is pretty much equivalent to s2idle). We can check in_s0ix, to
prevent the system from entering idle optimizations before it actually
enters hibernate (from display's perspective). Also, call
dc_set_power_state() before dc_allow_idle_optimizations(), since it's
safer to do so because dc_set_power_state() writes to DMUB.

[Why]
Since the surface/stream update flags aren't cleared after applying
updates, those same updates may be applied again in a future call to
update surfaces/streams for surfaces/streams that aren't actually part
of that update (i.e. applying an update for one surface/stream can
trigger unintended programming on a different surface/stream).
For example, when an update results in a call to
program_front_end_for_ctx, that function may call program_pipe on all
pipes. If there are surface update flags that were never cleared on the
surface some pipe is attached to, then the same update will be
programmed again.
[How]
Clear the surface and stream update flags after applying the updates.
