  Fix the problem with the IPI for the lazy context switching of the
  high FP registers. It was not that the IPI got lost due to the
  perceived unreliability of the IPI delivery, but rather that the
  IPI was not assigned a vector (ugh). Sending a 0 vector to a CPU
  results in a stray external interrupt.
  Add a KASSERT to ipi_send() to catch this. The initialization of
  the IPIs could be better, but it's not at all sure what the future
  of the code is. Avoid wasting a lot of time on something that is
  going to be rewritten anyway.
