    [PATCH] Update ADB drivers in 2.5 · 121c2e79
    Paul Mackerras authored
    This updates the ADB driver and the three low-level ADB bus adaptor
    drivers used on powermacs.  The files affected are all in
    drivers/macintosh; they are adb.c, macio-adb.c, via-cuda.c and
    via-pmu.c.
    
    The main changes in this patch are:
    
    - Remove the use of global cli/sti and replace them with local cli/sti,
      spinlocks and semaphores as appropriate.
    - Use DECLARE_WORK/schedule_work instead of tq_struct/schedule_task.
    - Improvements to the PMU interrupt handling and sleep/wakeup code.
