QAT devices perform an additional integrity check during compression by
decompressing the output. Starting from QAT GEN4, this verification is
done in-line by the hardware. However, on GEN2 devices, the hardware
reads back the compressed output from the destination buffer and performs
a decompression operation using it as the source.
In the current QAT driver, destination buffers are always marked as
write-only. This is incorrect for QAT GEN2 compression, where the buffer
is also read during verification. Since commit 6f5dc7658094
("iommu/vt-d: Restore WO permissions on second-level paging entries"),
merged in v6.16-rc1, write-only permissions are strictly enforced, leading
to DMAR errors when using QAT GEN2 devices for compression, if VT-d is
enabled.
Mark the destination buffers as DMA_BIDIRECTIONAL. This ensures
compatibility with GEN2 devices, even though it is not required for
QAT GEN4 and later.

Use touch-overlay to support overlay objects such as buttons and a

Some touch devices provide mechanical overlays with different objects
like buttons or clipped touchscreen surfaces.
In order to support these objects, add a series of helper functions
to the input subsystem to transform them into overlay objects via
device tree nodes.
These overlay objects consume the raw touch events and report the
expected input events depending on the object properties.
Note that the current implementation allows for multiple definitions
of touchscreen areas (regions that report touch events), but only the
first one will be used for the touchscreen device that the consumers
typically provide.
Should the need for multiple touchscreen areas arise, additional
touchscreen devices would be required at the consumer side.
There is no limitation in the number of touch areas defined as buttons.

Currently only F23 is correctly mapped for PS/2 keyboards.
According to this table:
https://download.microsoft.com/download/1/6/1/161ba512-40e2-4cc9-843a-923143f3456c/translate.pdf
- F24 and Zenkaku/Hankaku share the same scancode, but since in real world
Zenkaku/Hankaku keys seem to just use the tilde scancode, this patch binds the
scancode to F24. Note that on userspace side the KEY_ZENKAKUHANKAKU keycode is
currently not bound in xkeyboard-config, so it is (mostly*) unused anyway.
* Qt on Wayland and therefore KDE on Wayland can see the keypress anyway for
some reason and it is actually used in a touchpad toggle shortcut, but this is
currently being fixed in both KDE and xkeyboard-config to make this less weird,
so it could directly be fixed to correctly handle the F24 keypress instead.
- The scancodes for F13-F22 are currently unmapped so there will probably be no
harm in mapping them. This would also fix the issue that some of these keys
can't be mapped as the target from userspace using the `setkeycodes` command.

Many controllers these days have started including grip buttons. As
there has been no particular assigned BTN_* constants for these, they've

Since dance pads can have both up/down or left/right pressed at the same time,
by design, they are not suitable for mapping the buttons to axes. Historically,
this driver mapped the D-pad to BTN_TRIGGER_HAPPY1-4 in these cases, and before
that as mouse buttons. However, BTN_DPAD_* exists for this and makes far more
sense than the arbitrary mapping it was before.

A few drivers that use the legacy GPIOLIB interfaces can be enabled
even when GPIOLIB is disabled entirely. With my previous patch this
now causes build failures like:
drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt':
drivers/nfc/s3fwrn5/uart.c:100:14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration]
These did not show up in my randconfig tests because randconfig almost
always has GPIOLIB selected by some other driver, and I did most
of the testing with follow-up patches that address the failures
properly.
Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment
to avoid the build failures. It can be moved back and turned off by
default once all the driver specific changes are merged.

There is no break time in the while() loop, so every time at the end of
igb_xmit_zc(), negative overflow of nb_pkts will occur, which renders
the return value always false. But theoretically, the result should be
set after calling xsk_tx_peek_release_desc_batch(). We can take
i40e_xmit_zc() as a good example.
Returning false means we're not done with transmission and we need one
more poll, which is exactly what igb_xmit_zc() always did before this
patch. After this patch, the return value depends on the nb_pkts value.
Two cases might happen then:
1. if (nb_pkts < budget), it means we process all the possible data, so
return true and no more necessary poll will be triggered because of
this.
2. if (nb_pkts == budget), it means we might have more data, so return
false to let another poll run again.

A negative overflow can happen when the budget number of descs are
consumed. as long as the budget is decreased to zero, it will again go
into while (budget-- > 0) statement and get decreased by one, so the
overflow issue can happen. It will lead to returning true whereas the
expected value should be false.
In this case where all the budget is used up, it means zc function
should return false to let the poll run again because normally we
might have more data to process. Without this patch, zc function would
return true instead.

The existing PowerNV hotplug code did not handle surprise plug events
correctly, leading to a complete failure of the hotplug system after device
removal and a required reboot to detect new devices.
This comes down to two issues:
1) When a device is surprise removed, often the bridge upstream
port will cause a PE freeze on the PHB. If this freeze is not
cleared, the MSI interrupts from the bridge hotplug notification
logic will not be received by the kernel, stalling all plug events
on all slots associated with the PE.
2) When a device is removed from a slot, regardless of surprise or
programmatic removal, the associated PHB/PE ls left frozen.
If this freeze is not cleared via a fundamental reset, skiboot
is unable to clear the freeze and cannot retrain / rescan the
slot. This also requires a reboot to clear the freeze and redetect
the device in the slot.
Issue the appropriate unfreeze and rescan commands on hotplug events,
and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.

When the root of a nested PCIe bridge configuration is unplugged, the
pnv_php driver leaked the allocated IRQ resources for the child bridges'
hotplug event notifications, resulting in a panic.
Fix this by walking all child buses and deallocating all its IRQ resources
before calling pci_hp_remove_devices().
Also modify the lifetime of the workqueue at struct pnv_php_slot::wq so
that it is only destroyed in pnv_php_free_slot(), instead of
pnv_php_disable_irq(). This is required since pnv_php_disable_irq() will
now be called by workers triggered by hot unplug interrupts, so the
workqueue needs to stay allocated.

way of storing timestamp directly in a reserved field inside the PTP
message header is not suitable for use with the current Linux PTP stack
implementation. It is necessary to disable the PTP function to not
interfere the normal operation of the MAC.
Note the PTP driver for KSZ switches does not work for KSZ8463 and is not

KSZ8463 switch is a 3-port switch based from KSZ8863. Its major
difference from other KSZ SPI switches is its register access is not a
simple continual 8-bit transfer with automatic address increase but uses
a byte-enable mechanism specifying 8-bit, 16-bit, or 32-bit access. Its
registers are also defined in 16-bit format because it shares a design
with a MAC controller using 16-bit access. As a result some common
register accesses need to be re-arranged.
This patch adds the basic structure for using KSZ8463. It cannot use the
same regmap table for other KSZ switches as it interprets the 16-bit
value as little-endian and its SPI commands are different.
KSZ8463 uses a byte-enable mechanism to specify 8-bit, 16-bit, and 32-bit
access. The register is first shifted right by 2 then left by 4. Extra
4 bits are added. If the access is 8-bit one of the 4 bits is set. If
the access is 16-bit two of the 4 bits are set. If the access is 32-bit
all 4 bits are set. The SPI command for read or write is then added.
Because of this register transformation separate SPI read and write
functions are provided for KSZ8463.
KSZ8463's internal PHYs use standard PHY register definitions so there is
no need to remap things. However, the hardware has a bug that the high
word and low word of the PHY id are swapped. In addition the port
registers are arranged differently so KSZ8463 has its own mapping for
port registers and PHY registers. Therefore the PORT_CTRL_ADDR macro is
replaced with the get_port_addr helper function.

The first patch is by Khaled Elnaggar and converts the janz-ican3
driver's fwinfo_show() to sysfs_emit().
Vincent Mailhol contributes 3 patches that first fix a warning in the
ti_hecc driver and then add missing COMPILE_TEST more compile
coverage to the ti_hecc and tscan1 driver.
Randy Dunlap's patch let's the tscan1 driver depend on PC104.
A patch by Luis Felipe Hernandez fixes a kernel-doc error in the

libie: commonize adminq structure
Michal Swiatkowski says:
It is a prework to allow reusing some specific Intel code (eq. fwlog).
Move common *_aq_desc structure to libie header and changing
it in ice, ixgbe, i40e and iavf.
Only generic adminq commands can be easily moved to common header, as
rest is slightly different. Format remains the same. It will be better
to correctly move it when it will be needed to commonize other part of
the code.
Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
i40e: use libie_aq_str
iavf: use libie_aq_str

Remote IPsec tunnel endpoint may refer to a network segment that is
not directly connected to the host. In such a case, IPsec tunnel
endpoints are connected to a router and reachable via a routing path.
In IPsec packet offload mode, HW is initialized with the MAC address
of both IPsec tunnel endpoints.
Extend the current IPsec init MACs procedure to resolve nexthop for
routed networks. Direct neighbour lookup and probe is still used
for directly connected networks and as a fallback mechanism if fib
lookup fails.

Rework the read and write code paths in the driver to support operation
in atomic contexts. To achieve this, the driver must not rely on IRQs
or perform any scheduling, e.g., via a sleep or schedule routine.
Implement atomic, sleep-free, and IRQ-less operation. This increases
complexity but is necessary for atomic I2C transfers required by some
hardware configurations, e.g., to trigger reboots on an external PMIC chip.
