  SVN rev 193154 on 2009-05-31 08:11:39Z by adrian
  
  Fix the MP IPI code to differentiate between bitmapped IPIs and function IPIs.
  
  This attempts to fix the IPI handling code to correctly differentiate
  between bitmapped IPIs and function IPIs. The Xen IPIs were on low numbers
  which clashed with the bitmapped IPIs.
  
  This commit bumps those IPI numbers up to 240 and above (just like in the i386
  code) and fiddles with the ipi_vectors[] logic to call the correct function.
  
  This still isn't "right". Specifically, the IPI code may work fine for TLB
  shootdown events but the rendezvous/lazypmap IPIs are thrown by calling ipi_*()
  routines which don't set the call_func stuff (function id, addr1, addr2) that
  the TLB shootdown events are. So the Xen SMP support is still broken.
