Now that obsolete RFC3517/RFC6675 TCP loss detection has been removed, we can remove the somewhat complex and intrusive code to maintain its hint state: lost_skb_hint and lost_cnt_hint. This commit makes tcp_clear_retrans_hints_partial() empty. We will remove tcp_clear_retrans_hints_partial() and its call sites in the next commit.

2025-06-18tcp: remove obsolete and unused RFC3517/RFC6675 loss recovery codeNeal Cardwell1-3/+5
RACK-TLP loss detection has been enabled as the default loss detection algorithm for Linux TCP since 2018, in: commit b38a51fec1c1 ("tcp: disable RFC6675 loss detection") In case users ran into unexpected bugs or performance regressions, that commit allowed Linux system administrators to revert to using RFC3517/RFC6675 loss recovery by setting net.ipv4.tcp_recovery to 0. In the seven years since 2018, our team has not heard reports of anyone reverting Linux TCP to use RFC3517/RFC6675 loss recovery, and we can't find any record in web searches of such a revert. RACK-TLP was published as a standards-track RFC, RFC8985, in February 2021. Several other major TCP implementations have default-enabled RACK-TLP at this point as well. RACK-TLP offers several significant performance advantages over RFC3517/RFC6675 loss recovery, including much better performance in the common cases of tail drops, lost retransmissions, and reordering. It is now time to remove the obsolete and unused RFC3517/RFC6675 loss recovery code. This will allow a substantial simplification of the Linux TCP code base, and removes 12 bytes of state in every tcp_sock for 64-bit machines (8 bytes on 32-bit machines). To arrange the commits in reasonable sizes, this patch series is split into 3 commits. The following 2 commits remove bookkeeping state and code that is no longer needed after this removal of RFC3517/RFC6675 loss recovery.

2025-06-17dt-bindings: HID: i2c-hid: elan: Introduce Elan eKTH8D18Chen-Yu Tsai1-5/+7
The Elan eKTH8D18 touchscreen controller is an I2C HID device with a longer boot-up time. Power sequence timing wise it is compatible with the eKTH6A12NAY, with a power-on delay of at least 5ms, 20ms out-of-reset for I2C ack response, and 150ms out-of-reset for I2C HID enumeration, both shorter than what the eKTH6A12NAY requires. Enumeration and subsequent operation follows the I2C HID standard. Add a compatible string for it with the ekth6a12nay one as a fallback. No enum was used as it is rare to actually add new entries. These chips are commonly completely backward compatible, and unless the power sequencing delays change, there is no real effort being made to keep track of new parts, which come out constantly. Also drop the constraints on the I2C address since it's not really part of the binding.

2025-06-17workqueue: Add new WQ_PERCPU flagMarco Crivellari1-0/+6
Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. This patch adds a new WQ_PERCPU flag to explicitly request the use of the per-CPU behavior. Both flags coexist for one release cycle to allow callers to transition their calls. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default. tj: Merged doc patch.

2025-06-17dt-bindings: gpio: gpio-xilinx: Mark clocks as required propertyMichal Simek2-0/+2
On Microblaze platforms there is no need to handle clocks because the system is starting with clocks enabled (can be described via fixed clock node or clock-frequency property or not described at all). With using soft IPs with SOC platforms there is mandatory to handle clocks as is explained in commit 60dbdc6e08d6 ("dt-bindings: net: emaclite: Add clock support"). That's why make clock as required in dt binding because it is present in both configurations and should be described even there is no way how to handle it on Microblaze systems. There is also need to describe missing axi gpio clock in fpga-region.yaml not to introduce new error when make dt_binding_check runs.

2025-06-17dt-bindings: dmaengine: Add dma multiplexer for CV18XX/SG200X series SoCInochi Amaoto1-0/+51
The DMA IP of Sophgo CV18XX/SG200X is based on a DW AXI CORE, with an additional channel remap register located in the top system control area. The DMA channel is exclusive to each core. In addition, the DMA multiplexer is a subdevice of system controller, so this binding only contains necessary properties for the multiplexer itself. Add the dmamux binding for CV18XX/SG200X series SoC.

2025-06-16ima: add a knob ima= to allow disabling IMA in kdump kernelBaoquan He1-0/+5
Kdump kernel doesn't need IMA functionality, and enabling IMA will cost extra memory. It would be very helpful to allow IMA to be disabled for kdump kernel. Hence add a knob ima=on|off here to allow turning IMA off in kdump kernel if needed. Note that this IMA disabling is limited to kdump kernel, please don't abuse it in other kernel and thus serious consequences are caused.

2025-06-16thermal: intel: int340x: Add throttling control interface to PTCSrinivas Pandruvada1-0/+9
Firmware-based thermal temperature control loops may aggressively throttle performance to prevent temperature overshoots relative to the defined target temperature. This can negatively impact performance. User space may prefer to prioritize performance, even if it results in temperature overshoots with in acceptable range. For example, user space might tolerate temperature overshoots when the device is placed on a desk, as opposed to when it's on a lap. To accommodate such scenarios, an optional attribute is provided to specify a tolerance level for temperature overshoots while maintaining acceptable performance. Attribute: thermal_tolerance: This attribute ranges from 0 to 7, where 0 represents the most aggressive control to avoid any temperature overshoots, and 7 represents a more graceful approach, favoring performance even at the expense of temperature overshoots. Note: This level may not scale linearly. For example, a value of 3 does not necessarily imply a 50% improvement in performance compared to a value of 0.
