2025-07-27crypto: qat - fix seq_file position update in adf_ring_next()Giovanni Cabiddu1-1/+3
The `adf_ring_next()` function in the QAT debug transport interface fails to correctly update the position index when reaching the end of the ring elements. This triggers the following kernel warning when reading ring files, such as /sys/kernel/debug/qat_c6xx_<D:B:D:F>/transport/bank_00/ring_00: [27725.022965] seq_file: buggy .next function adf_ring_next [intel_qat] did not update position index Ensure that the `*pos` index is incremented before returning NULL when after the last element in the ring is found, satisfying the seq_file API requirements and preventing the warning.

2025-07-27crypto: qat - fix DMA direction for compression on GEN2 devicesGiovanni Cabiddu2-5/+5
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.

2025-07-27Input: touch-overlay - add touchscreen overlay handlingJavier Carrasco4-1/+310
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.

2025-07-27dt-bindings: touchscreen: add touch-overlay propertyJavier Carrasco1-0/+119
The touch-overlay encompasses a number of touch areas that define a clipped touchscreen area and/or buttons with a specific functionality. A clipped touchscreen area avoids getting events from regions that are physically hidden by overlay frames. For touchscreens with printed overlay buttons, sub-nodes with a suitable key code can be defined to report key events instead of the original touch events.

2025-07-27Input: atkbd - correctly map F13 - F24Werner Sembach1-6/+6
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.

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.

2025-07-27gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIBArnd Bergmann1-2/+2
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.

At this point, with the other recent MAINTAINERS changes, this should now mean that every memory management-related file has a section and assigned maintainers/reviewers. Finally, we copy across the maintainers/reviewers from MEMORY MANAGEMENT - CORE to MEMORY MANAGEMENT - MISC, as it seems the two are sufficiently related for this to be sensible.
