New Revision: 214448
URL: http://svn.freebsd.org/changeset/base/214448

Log:
  Use 'PCPU_GET(apic_id)' to determine the BSP's APIC ID on a UP machine
  when routing interrupts instead of cpu_apic_ids[0] since cpu_apic_ids[]
  is only populated for multiple-CPU machines.  This also matches what the
  code does when SMP is not enabled.
