In case a reporter exists, error message is logged only to the devlink
tracer. The devlink tracer is a visibility utility only, which user can
choose not to monitor.
After cited patch, 3rd party monitoring tools that tracks these error
message will no longer find them in dmesg, causing a regression.
With this patch, error messages are also logged into the dmesg.

Following scenario easily break driver logic and crash the kernel:
1. Add rule with mirred actions to same device.
2. Delete this rule.
In described scenario rule is not added to database and on deletion
driver access invalid entry.
Example:
$ tc filter add dev ens1f0_0 ingress protocol ip prio 1 \
flower skip_sw \
action mirred egress mirror dev ens1f0_1 pipe \
action mirred egress redirect dev ens1f0_1
$ tc filter del dev ens1f0_0 ingress protocol ip prio 1

Unfortunately hardware where this causes a failure is not widely

With these patches reverted nothing fatal happens, TPM is fallbacked

there are no high throughput workloads for TPM).

The 6390 family uses an extended register to set the port connected to
the CPU. The lower 5 bits indicate the port, the upper three bits are
the priority of the frames as they pass through the switch, what
egress queue they should use, etc. Since frames being set to the CPU
are typically management frames, BPDU, IGMP, ARP, etc set the priority
to 7, the reset default, and the highest.

"SAMSUNG" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with

Serdev sub-system claims all ACPI serial devices that are not already
initialised. As a result, no device node is created for serial ports
on certain boards such as the Apollo Lake based UP2. This has the
unintended consequence of not being able to raise the login prompt via
serial connection.
Introduce a blacklist to reject ACPI serial devices that should not be
claimed by serdev sub-system. Add the peripheral ids for Intel HS UART
to the blacklist to bring back serial port on SoCs carrying them.

It turns out that even though endpoints with a maxpacket length of 0
aren't useful for data transfer, the descriptors do serve other
purposes. In particular, skipping them will also skip over other
class-specific descriptors for classes such as UVC. This unexpected
side effect has caused some UVC cameras to stop working.
In addition, the USB spec requires that when isochronous endpoint
descriptors are present in an interface's altsetting 0 (which is true
on some devices), the maxpacket size _must_ be set to 0. Warning
about such things seems like a bad idea.
This patch updates an earlier commit which would log a warning and
skip these endpoint descriptors. Now we only log a warning, and we
don't even do that for isochronous endpoints in altsetting 0.
We don't need to worry about preventing endpoints with maxpacket = 0
from ever being used for data transfers; usb_submit_urb() already
checks for this.

The only clk init function in this driver that register a clk is
fu540_c000_clk_init(), and thus we need to unregister the clk when this
driver is removed on that platform. Other init functions, for example
macb_clk_init(), don't register clks and therefore we shouldn't
unregister the clks when this driver is removed. Convert this
registration path to devm so it gets auto-unregistered when this driver
is removed and drop the clk_unregister() calls in driver remove (and
error paths) so that we don't erroneously remove a clk from the system
that isn't registered by this driver.
Otherwise we get strange crashes with a use-after-free when the
devm_clk_get() call in macb_clk_init() calls clk_put() on a clk pointer
that has become invalid because it is freed in clk_unregister().

Atomic operations that span cache lines are super-expensive on x86
(not just to the current processor, but also to other processes as all
memory operations are blocked until the operation completes). Upcoming
x86 processors have a switch to cause such operations to generate a #AC
trap. It is expected that some real time systems will enable this mode
in BIOS.
In preparation for this, it is necessary to fix code that may execute
atomic instructions with operands that cross cachelines because the #AC
trap will crash the kernel.
Since "pwol_mask" is local and never exposed to concurrency, there is
no need to set bits in pwol_mask using atomic operations.
Directly operate on the byte which contains the bit instead of using
__set_bit() to avoid any big endian concern due to type cast to
unsigned long in __set_bit().

hlos1_vote_mmnoc_mmu_tbu_sf_gdsc status stuck at 'on'
hlos1_vote_mmnoc_mmu_tbu_hf1_gdsc status stuck at 'on'
hlos1_vote_mmnoc_mmu_tbu_hf0_gdsc status stuck at 'on'
hlos1_vote_aggre_noc_mmu_tbu2_gdsc status stuck at 'on'
hlos1_vote_aggre_noc_mmu_tbu1_gdsc status stuck at 'on'
hlos1_vote_aggre_noc_mmu_pcie_tbu_gdsc status stuck at 'on'
hlos1_vote_aggre_noc_mmu_audio_tbu_gdsc status stuck at 'on'
As the name of these GDSCs suggests, they are "votable" and in downstream
DT, they all have the property "qcom,no-status-check-on-disable", which
means that we should not poll the status bit when we disable them.
Luckily the VOTABLE flag already exists and it does exactly what we need,
so let's make use of it to make the warnings disappear.

"IRQ_TIMER", used in the arch/riscv CSR header file, is a sufficiently
generic macro name that it's used by several source files across the
Linux code base. Some of these other files ultimately include the
arch/riscv CSR include file, causing collisions. Fix by prefixing the
RISC-V csr.h IRQ_ macro names with an RV_ prefix.

When enabling ftrace graph tracer, it gets the tracing clock in
ftrace_push_return_trace(). Eventually, it invokes riscv_sched_clock()
to get the clock value. If riscv_sched_clock() isn't marked with
'notrace', it will call ftrace_push_return_trace() and cause infinite
loop.
The result of failure as follow:

[Why]
According to DP spec, it should shift left 4 digits for NO_STOP_BIT
in REMOTE_I2C_READ message. Not 5 digits.
In current code, NO_STOP_BIT is always set to zero which means I2C
master is always generating a I2C stop at the end of each I2C write
transaction while handling REMOTE_I2C_READ sideband message. This issue
might have the generated I2C signal not meeting the requirement. Take
random read in I2C for instance, I2C master should generate a repeat
start to start to read data after writing the read address. This issue
will cause the I2C master to generate a stop-start rather than a
re-start which is not expected in I2C random read.
[How]
Correct the shifting value of NO_STOP_BIT for DP_REMOTE_I2C_READ case in
drm_dp_encode_sideband_req().
Changes since v1:(https://patchwork.kernel.org/patch/11312667/)

When a TID RDMA ACK to RESYNC request is received, the flow PSNs for
pending TID RDMA WRITE segments will be adjusted with the next flow
generation number, based on the resync_psn value extracted from the flow
PSN of the TID RDMA ACK packet. The resync_psn value indicates the last
flow PSN for which a TID RDMA WRITE DATA packet has been received by the
responder and the requester should resend TID RDMA WRITE DATA packets,
starting from the next flow PSN.
However, if resync_psn points to the last flow PSN for a segment and the
next segment flow PSN starts with a new generation number, use of the old
resync_psn to adjust the flow PSN for the next segment will lead to
miscalculation, resulting in WARN_ON and sge rewinding errors:

In the iowait structure, two iowait_work entries were included to queue a
given object: one for normal IB operations, and the other for TID RDMA
operations. For non-TID RDMA operations, the iowait_work structure for TID
RDMA is initialized to contain a NULL function (not used). When the QP is
reset, the function iowait_cancel_work will be called to cancel any
pending work. The problem is that this function will call
cancel_work_sync() for both iowait_work entries, even though the one for
TID RDMA is not used at all. Eventually, the call cascades to
__flush_work(), wherein a WARN_ON will be triggered due to the fact that
work->func is NULL.
The WARN_ON was introduced in commit 4d43d395fed1 ("workqueue: Try to
catch flush_work() without INIT_WORK().")
This patch fixes the issue by making sure that a work function is present
for TID RDMA before calling cancel_work_sync in iowait_cancel_work.

Current code use dma_wmb() to ensure Rx/Tx descriptors are visible
to device before writing to doorbell.
However, these dma_wmb() are wrong and unnecessary. Therefore,
they should be removed.
iowrite32be() called from gve_rx_write_doorbell()/gve_tx_put_doorbell()
should guaratee that all previous writes to WB/UC memory is visible to
device before the write done by iowrite32be().
E.g. On ARM64, iowrite32be() calls __iowmb() which expands to dma_wmb()
and only then calls __raw_writel().

Some adapters need a fence Work Entry to handle retransmission. Currently
the driver checks for this condition, only if the Send queue entry is
signalled. Implement the condition check, irrespective of the signalled
state of the Work queue entries
Failure to add the fence can result in access to memory that is already
marked as completed, triggering data corruption, transmission failure,
IOMMU failures, etc.

A struct that needs to be aligned to 32 bytes has a size of 28. Increase
the size to 32.
This makes elements of arrays of this struct aligned to 32 as well, and
other structs where members are aligned to 32 mixing
ipu3_uapi_awb_fr_config_s as well as other types.

The Advantech PCI-1713 has 32 analog input channels, but an incorrect
bit-mask in the definition of the `PCI171X_MUX_CHANH(x)` and
PCI171X_MUX_CHANL(x)` macros is causing channels 16 to 31 to be aliases
of channels 0 to 15. Change the bit-mask value from 0xf to 0xff to fix
it. Note that the channel numbers will have been range checked already,
so the bit-mask isn't really needed.
