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.
