    Pull workqueue updates from Tejun Heo:

     - Rework the rescuer to process work items one-by-one instead of
       slurping all pending work items in a single pass.

       As there is only one rescuer per workqueue, a single long-blocking
       work item could cause high latency for all tasks queued behind it,
       even after memory pressure is relieved and regular kworkers become
       available to service them.

     - Add CONFIG_BOOTPARAM_WQ_STALL_PANIC build-time option and
       workqueue.panic_on_stall_time parameter for time-based stall panic,
       giving systems more control over workqueue stall handling.

     - Replace BUG_ON() with panic() in the stall panic path for clearer
       intent and more informative output.
