  Log:
  A clean fix for the spl "deadlock before smp_active" problem.
  
  Added a new variable, 'bsp_apic_ready', which is set as soon as the bootstrap
  CPU has initialized its local APIC.  Conditionalize the GENSPLR functions
  to call ss_lock ONLY after bsp_apic_ready is TRUE;  This should prevent
  any problems with races between the time the 1st AP becomes ready and the
  time smp_active is set.
