  Excellent.  I'm building code now, and will let you know when I test
it how far I get.  I'll try first on a Ultra2 with dual-USI's.  I have
a pair of 300Mhz USIIs for it too.

  I had a question, though.  First, what is a Spitfire?  What does
this cover?  Also, I notice the code in sparc64_send_ipi() to work
around SpitFire erratum #54.  Should that code be protected either
by the pre-processor macro, or better a run-time test to see if
it's running on a SpitFire?

  Thanks!
