Hi Kaoru,

  I tried your patch on my 2 way Power3 Model 270 RS/6000 just before I
left but didn't have enough time to write this note until now.

  Your patch amazingly booted my box quite a bit further... it still
dies for me but in a new and interesting way, that doesn't appear to be
related to the page_table_lock. (Token Ring and shared memory
...sigh...)

  The part that REALLY REALLY bothers me tho is why does this patch
work? I *HAVE* CONFIG_SMP on... least I think I do... there's two
penguins on my screen ... two processors grinding away ... that's
CONFIG_SMP right??? I'm not losing my mind am I?

  So assuming that CONFIG_SMP is on, this patch shouldn't yeild anything
different what so ever from a codegen perspective with or without the
patch for an SMP kernel build. It doesn't make sense.

He is just commenting out those lines.  They are not "#ifdef CONFIG_SMP".
