2025-12-08drm/amd/display: Use GFP_ATOMIC in dc_create_plane_state()Alex Deucher

2025-12-08drm/amdkfd: Trap handler support for expert scheduling modeJay Cornwall
The trap may be entered with dependency checking disabled. Wait for dependency counters and save/restore scheduling mode. v2: Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized. While the trap handler does zero this field before use, a user-mode second-level trap handler could not rely on this being zero when using an older kernel mode driver. v3: Use ttmp11 primarily but copy to ttmp1 before jumping to the second level trap handler. ttmp1 is inspectable by a debugger. Unexpected bits in the unused space may regress existing software.

2025-12-08workqueue: Process extra works in rescuer on memory pressureLai Jiangshan
Make the rescuer process more work on the last pwq when there are no more to rescue for the whole workqueue to help the regular workers in case it is a temporary memory pressure relief and to reduce relapse.

2025-12-08workqueue: Process rescuer work items one-by-one using a cursorLai Jiangshan
Previously, the rescuer scanned for all matching work items at once and processed them within a single rescuer thread, which could cause one blocking work item to stall all others. Make the rescuer process work items one-by-one instead of slurping all matches in a single pass. Break the rescuer loop after finding and processing the first matching work item, then restart the search to pick up the next. This gives normal worker threads a chance to process other items which gives them the opportunity to be processed instead of waiting on the rescuer's queue and prevents a blocking work item from stalling the rest once memory pressure is relieved. Introduce a dummy cursor work item to avoid potentially O(N^2) rescans of the work list. The marker records the resume position for the next scan, eliminating redundant traversals. Also introduce RESCUER_BATCH to control the maximum number of work items the rescuer processes in each turn, and move on to other PWQs when the limit is reached.
