      [PATCH] ia64: New CMC/CPE polling · 765a8447
      Alex Williamson authored
      Here's a redesign of the CMC and CPE polling for both 2.6.0-test2
      and 2.4.21.  This is roughly the same design I requested comment on
      a while back (BTW, nobody commented...).  Basically, rather than
      flooding all the cpus in parallel, I used some low priority interrupts
      to cascade through the cpus.  This should be much more scalable.  I
      also added a new feature of enabling interrupts for the CMC and CPE
      handlers.  The SAL spec claims these functions are SMP safe and
      re-entrant and even recommends that the corrected error handlers
      should run with interrupts enabled.  It works on HP boxes, others
      might want to double check that their firmware adheres to the spec.
      The combination of these things should keep polling from impacting
      system response time.
