  It is possible for spurious interrupt(s) to be posted to an AP cpu
  while the cpu is being bootstrapped.  Explicitly enable interrupts
  while still in a critical section near the end of ap_init to allow
  the cpu to issue the interrupt vector(s), then clear the software
  interrupt pending fields in the globaldata structure.
  This stops the single report to the console of a spurious interrupt
  occuring during AP booting.  This problem is unrelated to the multitude
  of spurious interrupts that can be reported during device initialization.
  Those will probably still occur.
