max_brightness is used in ideapad_kbd_bl_brightness_get() before it's set,
causing ideapad_kbd_bl_brightness_get() to return -EINVAL sometimes.

When in the list_for_each_entry iteration, reload of p->state->settings
with a local setting from old_state will turn the list iteration into an
infinite loop.
The typical symptom when the issue happens, will be a printk message like:
"not freeing pin xx (xxx) as part of deactivating group xxx - it is
already used for some other setting".
This is a compiler-dependent problem, one instance occurred using Clang
version 10.0 on the arm64 architecture with linux version 4.19.

The usage count of struct dev_pm_info is an implementation detail that
is only available if CONFIG_PM is enabled, so printing it in a debug message
causes a build failure in configurations without PM:

The print message does not seem essential, so the easiest workaround is
to just remove it.

Modify the internal bind- and unbind-interfaces to take a struct
irq_info parameter. When allocating a new IRQ pass the pointer from
the allocating function further up.
This will reduce the number of info_for_irq() calls and make the code
more efficient.

Instead of having a common function for allocating a single IRQ or a
consecutive number of IRQs, split up the functionality into the callers
of xen_allocate_irqs_dynamic().
This allows to handle any allocation error in xen_irq_init() gracefully
instead of panicing the system. Let xen_irq_init() return the irq_info
pointer or NULL in case of an allocation error.
Additionally set the IRQ into irq_info already at allocation time, as
otherwise the IRQ would be '0' (which is a valid IRQ number) until
being set.

Netpoll will explicilty pass the polling call with a budget of 0 to
indicate it's clearing the Tx path only. For the gve_rx_poll and
gve_xdp_poll, they were mistakenly taking the 0 budget as the indication
to do all the work. Add check to avoid the rx path and xdp path being
called when budget is 0. And also avoid napi_complete_done being called
when budget is 0 for netpoll.

====================
Intel Wired LAN Driver Updates 2023-11-13 (ice)
This series contains updates to ice driver only.
Arkadiusz ensures the device is initialized with valid lock status
value. He also removes range checking of dpll priority to allow firmware
to process the request; supported values are firmware dependent.
Finally, he removes setting of can change capability for pins that
cannot be changed.
Dan restores ability to load a package which doesn't contain a signature
segment.

Use the qcq's interrupt index, not the irq number, to mask
the interrupt. Since the irq number can be out of range from
the number of possible interrupts, we can end up accessing
and potentially scribbling on out-of-range and/or unmapped
memory, making the kernel angry.

The while loop condition verifies 'count < limit'. Neither value change
before the 'count >= limit' check. As is this check is dead code. But
code inspection reveals a code path that modifies 'count' and then goto
'drain_data' and back to 'read_again'. So there is a need to verify
count value sanity after 'read_again'.
Move 'read_again' up to fix the count limit check.

checks for NULL. Also we need to propagate the error pointer back to
the callers in r535_gsp_rpc_get(). Returning NULL will lead to a NULL

If a task completion notification (TCN) is received when there is no
outstanding task, the cqhci driver issues a "spurious TCN" warning. This
was observed to happen right after CQE error recovery.
When an error interrupt is received the driver runs recovery logic.
It halts the controller, clears all pending tasks, and then re-enables
it. On some platforms, like Intel Jasper Lake, a stale task completion
event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set.
This results in either:
a) Spurious TC completion event for an empty slot.
b) Corrupted data being passed up the stack, as a result of premature
completion for a newly added task.
Rather than add a quirk for affected controllers, ensure tasks are cleared
by toggling CQHCI_ENABLE, which would happen anyway if
cqhci_clear_all_tasks() timed out. This is simpler and should be safe and
effective for all controllers.

During CQE error recovery, error-free data commands get requeued if there
is any data left to transfer, but non-data commands are completed even
though they have not been processed. Requeue them instead.
Note the only non-data command is cache flush, which would have resulted in
a cache flush being lost if it was queued at the time of CQE recovery.

With "W=1" and "-Wformat-truncation" build options, the kernel test robot
found a possible string truncation warning in pinctrl-s32cc.c, which uses
an 8-byte char array to hold a memory region name "map%u". Since the
maximum number of digits that a u32 value can present is 10, and the "map"
string occupies 3 bytes with a termination '\0', which means the rest 4
bytes cannot fully present the integer "X" that exceeds 4 digits.
Here we check if the number >= 10000, which is the lowest value that
contains more than 4 digits.

evtchn_from_irq() and irq_from_virq() have a single external user and

The RX max frame size is over 10000 for the Gemini ethernet,
but the TX max frame size is actually just 2047 (0x7ff after
checking the datasheet). Reflect this in what we offer to Linux,
cap the MTU at the TX max frame minus ethernet headers.
We delete the code disabling the hardware checksum for large
MTUs as netdev->mtu can no longer be larger than
netdev->max_mtu meaning the if()-clause in gmac_fix_features()
is never true.

The Gemini ethernet controller provides hardware checksumming
for frames up to 1514 bytes including ethernet headers but not
FCS.
If we start sending bigger frames (after first bumping up the MTU
on both interfaces sending and receiving the frames), truncated
packets start to appear on the target such as in this tcpdump
resulting from ping -s 1474:
23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown),
ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing!
(tos 0x0, ttl 64, id 32653, offset 0, flags [DF], proto ICMP (1), length 1502)
OpenWrt.lan > Fecusia: ICMP echo request, id 1672, seq 50, length 1482
If we bypass the hardware checksumming and provide a software
fallback, everything starts working fine up to the max TX MTU
of 2047 bytes, for example ping -s2000 192.168.1.2:
00:44:29.587598 bc:ae:c5:6b:a8:3d (oui Unknown) > 14:d6:4d:a8:3c:4f (oui Unknown),
ethertype IPv4 (0x0800), length 2042:
(tos 0x0, ttl 64, id 51828, offset 0, flags [none], proto ICMP (1), length 2028)
Fecusia > OpenWrt.lan: ICMP echo reply, id 1683, seq 4, length 2008
The bit enabling to bypass hardware checksum (or any of the
"TSS" bits) are undocumented in the hardware reference manual.
The entire hardware checksum unit appears undocumented. The
conclusion that we need to use the "bypass" bit was found by
trial-and-error.
Since no hardware checksum will happen, we slot in a software
checksum fallback.
Check for the condition where we need to compute checksum on the
skb with either hardware or software using == CHECKSUM_PARTIAL instead
of != CHECKSUM_NONE which is an incomplete check according to
<linux/skbuff.h>.
On the D-Link DIR-685 router this fixes a bug on the conduit
interface to the RTL8366RB DSA switch: as the switch needs to add
space for its tag it increases the MTU on the conduit interface
to 1504 and that means that when the router sends packages
of 1500 bytes these get an extra 4 bytes of DSA tag and the
transfer fails because of the erroneous hardware checksumming,
affecting such basic functionality as the LuCI web interface.

Commit 9eed321cde22 ("net: lapbether: only support ethernet devices")
has been able to keep syzbot away from net/lapb, until today.
In the following splat [1], the issue is that a lapbether device has
been created on a bonding device without members. Then adding a non
ARPHRD_ETHER member forced the bonding master to change its type.
The fix is to make sure we call dev_close() in bond_setup_by_slave()
so that the potential linked lapbether devices (or any other devices
having assumptions on the physical device) are removed.
A similar bug has been addressed in commit 40baec225765
("bonding: fix panic on non-ARPHRD_ETHER enslave failure")

As I was working on a syzbot report, I found that KCSAN would
probably complain that reading q->head or q->tail without
barriers could lead to invalid results.
Add corresponding READ_ONCE() and WRITE_ONCE() to avoid
load-store tearing.

This reverts commit 8a4f030dbced6fc255cbe67b2d0a129947e18493.
Richard says:
The test itself is harmless, but keeping it will make people think,
"oh this pointer can be invalid."
In fact the core stack ensures that ioctl() can't be invoked after
release(), otherwise Bad Stuff happens.

Commit 3cbdb0343022 ("ice: Add support for E830 DDP package segment")
incorrectly removed support for package download for packages without a
signature segment. These packages include the signature buffer inline
in the configurations buffers, and not in a signature segment.
Fix package download by providing download support for both packages
with (ice_download_pkg_with_sig_seg()) and without signature segment
(ice_download_pkg_without_sig_seg()).

The dpll output pins which are used to feed clock signal of PHY and MAC
circuits cannot be disconnected, those integrated circuits require clock
signal for operation.
By stopping assignment of DPLL_PIN_CAPABILITIES_STATE_CAN_CHANGE pin
capability, prevent the user from invoking the state set callback on
those pins, setting the state on those pins already returns error, as
firmware doesn't allow the change of their state.

Supported priority value for input pins may differ with regard of NIC
firmware version. E810T NICs with 3.20/4.00 FW versions would accept
priority range 0-31, where firmware 4.10+ would support the range 0-9
and extra value of 255.
Remove the in-range check as the driver has no information on supported
values from the running firmware, let firmware decide if given value is
correct and return extack error if the value is not supported.

The drm CI scripts for gitlab have a requirements file that makes the
github 'dependabot' worry about a few of the required tooling versions.
It wants to update the pip requirements from 23.2.1 to 23.3:
"When installing a package from a Mercurial VCS URL, e.g. pip install
hg+..., with pip prior to v23.3, the specified Mercurial revision
could be used to inject arbitrary configuration options to the hg
clone call (e.g. --config). Controlling the Mercurial configuration
can modify how and which repository is installed. This vulnerability
does not affect users who aren't installing from Mercurial"
and upgrade the urllib3 requirements from 2.0.4 to 2.0.7 due to two
issues:
"urllib3's request body not stripped after redirect from 303 status
changes request method to GET"
"`Cookie` HTTP header isn't stripped on cross-origin redirects"
The file also ends up not having a newline at the end, that my editor
ends up wanting to fix automatically.

When delaying eoi handling of events, the related elements are queued
into the percpu lateeoi list. In case the list isn't empty, the
elements should be sorted by the time when eoi handling is to happen.
Unfortunately a new element will never be queued at the start of the
list, even if it has a handling time lower than all other list
elements.
Fix that by handling that case the same way as for an empty list.
