    kernel - Fix early boot interrupt race
    * Fix a null pointer dereference panic due to an interrupt
      race during early boot.  Interrupts are enabled before
      intr_block is allocated, so intr_block can be NULL.
    * Refactor the kmalloc() for intr_block to only allocate the
      space needed for ncpus.
