[patch] Shared interrupts with fast handlers

[Peter Grehan]

Hi Paolo,

  Not sure if you saw this, but you appear to have collided with some 
work Marcel did:

http://docs.freebsd.org/cgi/mid.cgi?137AEBF1-AB26-4806-AE29-7D05F7BF0CAF

  Would you be able to have a look at Marcel's patch and work with him 
to resolve any differences between his and yours ?

  BTW Marcel, I did a full release build with your patch and also 
verified that vmstat output is OK.

later,

Peter.
