Log:
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.
